Detailed ways

The present invention will be further described in detail below in conjunction with the performance and mechanism of action of the plant ecological protection agent and the examples given by the inventor.

1. Performance of plant ecological protection agent

The plant ecological protection agent is sprayed on the surface of the plant after compounding the high-fat film agent, and naturally forms a transparent ultra-thin film, which has the functions of preventing drought, cold, disease, insect, growth, stability, ripening, and ground growth. It has functions such as temperature preservation and moisture preservation. It is harmless, non-toxic, pollution-free and non-toxic. It is safe for humans, animals and plants, and belongs to the ecological protective agent.

2. Mechanism of action

The plant ecological protection agent is a modern biomimetic membrane technology and release control technology. The imitation membrane structure is chimerized with a special functional agent, which is released slowly and has a long-term effect. The mechanism of action of plant ecological protection agents belongs to the category of physical control, which can change the physiological activities of parasitic plants, prevent diseases and insect pests, and directly or indirectly achieve the purpose of disease prevention and production increase.

The plant ecological protection agent forms a transparent film on the surface of the plant, which is a closed film structure, which is closed and long-lasting, and is not easily washed away by rain. According to the principle of biofilm, particulate matter is embedded in the ultra-micro film, which is microporous and semi-permeable. To ensure the normal respiration of plants, while the water is kept on the surface of the plants, the invasion of pathogens is blocked, and the micro-ecological balance is adjusted to improve the physiological activities of plants. The ultra-micro film is compounded with a variety of biologically active substances, functional agents, etc., and evaporates water during metabolism. The functional elements and components of the inner layer of the film are separated out, so that the film has various functions such as antibacterial, coloring, rust removal, disease spot, smooth fruit surface, drought prevention, cold prevention, prevention of leggy growth, stable ripening surface, heat preservation and moisture preservation.

The plant ecological protection agent of the present invention, the chemical composition is mainly higher fatty acid or higher fatty alcohol, after chemical synthesis, it is milky, fragrant, white, neutral, non-polluting, non-volatile, and can be used with general sterilization, insecticides, nutritional agents Mixed use. It can be used for grain, cotton, oil, melon, fruit, vegetable, garden and other plants.

When using the plant ecological protection agent of the present invention, attention should be paid to spraying in the morning and evening, and the whole plant should be sprayed as much as possible during spraying, and mixed use with strong pesticides or alkaline substances should be avoided, so as not to cause hydrolysis and failure of the plant ecological protection agent.

When in use, put the plant ecological protection agent in warm water, heat and shake well, then dilute with water, and spray 25kg to 30kg per mu. Ground spraying type plant ecological protection agent, spray 50kg-75kg per mu. dosage form Applicable crop types main effect Dilution factor Spray time season Drought type various crops Drought and heat release 150～200 High temperature period, hot and dry wind period, drought period Cold type various crops Cold and low temperature protection 100～150 cooling period, cold period disease prevention type various crops 150～200 The whole growth period of plants and the early stage of disease onset Insect-proof various crops Small insects such as aphids, Lepidoptera, Coleoptera, Hemiptera pests 150～200 The whole growth period of plants and the early stage of insect development Facilitating various crops Promote the growth of roots, stems and leaves 150～200 Early and mid-plant growth Stable type Various crops and three types of fields control prosperity 150～200 Plant flourishing long term Ripening type Cotton and other late crops Ripening, fallen leaves, fallen flowers, fruits, bells 200 late plant growth Ground spray type various plants open field Increase temperature and keep moisture 50～200 After sowing, during growth

The following are application examples given by the inventors according to the above technical solutions.

1. Drought resistance and heat resistance and improve the survival rate of seedling transplanting

1.1 Anti-dry hot air

The experiment of using high-fat film to prevent and control the damage caused by dry and hot wind in the mature stage of wheat, sprayed the area once before wheat harvest (June 5), sprayed the area twice (May 25 and June 5) and sprayed the area three times (May 15) Day, May 25, June 5) thousand-grain weight increased by 1.4g, 1.8g and 2.1g respectively compared with 41.7g in CK area (spraying water). According to tests conducted by the Plant Protection Station of Luancheng County, Hebei Province, Shaanxi Plant Protection Institute, Cotton Institute, Hanzhong, Baoji Agricultural Science Institute, and Plant Protection Station, the thousand-grain weight of wheat sprayed with a high-fat film 150 times in the early flowering stage is 2g-3g higher than that of CK. Yield increased by more than 10% per ^hm2 . From 1998 to 2000, ^5.3hm2 was demonstrated in Zhangtun Village, Yunyang Town, Jingyang County, Shaanxi Province. The thousand-grain weight of spraying 200 times high-fat film was 2g higher than that without spraying, and the yield of wheat was increased by 600kg per ^hm2 . The input-output ratio is 1:30.

1.2 Improve the survival rate of seedling transplanting

When transplanting biennial citrus seedlings in Beipei, Sichuan, 400 citrus seedlings were sprayed with high-fat film one day before the seedlings were raised. After two days of transportation, and several exposures to the sun after planting, only 4% of the branches of the plants were dry and there were no dead plants. However, 35% of the plants that were not sprayed with high-fat film showed dry branches and a few plants withered leaves. Guangdong Province introduced high-fat film for multiple applications. Vegetable seedlings sprayed with high-fat film and then transplanted can reduce dead seedlings by 50%-80%. , Significantly improve the survival rate, the average increase of 30% -50% than the unsprayed. Seedlings in Xiqi Village, Dongqi Township, Dali County, Shaanxi Province were transplanted to plant watermelons. Before planting, they were sprayed with high-fat film 150 times liquid. After planting, it was observed that new leaves grew three days earlier.

1.1.3 Reduce water transpiration and improve plant drought tolerance

In the research on the application of high-fat film in the cotton system where the cotton is located in Shaanxi Province, on July 23, the cotton plants were sprayed with 150 times of high-fat film and CK, and by August 4, the transpiration intensity was measured by weighing method. CK and sprayed with high-fat film 1.21gH ₂ O/dm ² /h and 1.03gH ₂ O/dm ² /h respectively; the whole day is counted as 10h, the water transpired by leaves per hm ² cotton field per day, the sprayed high lipid film is more than the unsprayed CK It can reduce 7500kg; and it is observed that the top leaves of the cotton plants sprayed with high-fat film do not wilt (lower rim) at 2-3 hours in the afternoon, and the cotton plants that are not sprayed with high-fat film appear wilting phenomenon, which proves that high-fat film can enhance plant tolerance Drought ability is beneficial to maintain normal physiological activities, significantly reduce the shedding of bells, and play a role in increasing production.

2. Anti-cold and anti-freeze

2.1 Overwintering experiment of protected trees in citrus northward migration area

In Xinxiang, Henan Province and other places, the lowest winter temperature was -11.5°C, and the 400 citrus trees protected by high-fat film had no fallen leaves and dead branches, and only the leaves turned slightly yellow, but they could still survive the winter safely; The control citrus trees all lost their leaves, and some branches died.

2.2 Prolong the growth period of crops

The Shaanxi Provincial Cotton Research Institute used high-fat film to protect the early sowing period of mulched cotton for 10d-15d, avoiding the climatic factors of severe boll rot caused by autumn rain, and increased the yield of mulched cotton by 10.3% on average in 3 years. A simulated test of using 2 pieces of true-leaf cotton seedlings sprayed with high-fat film and CK cotton seedlings without spraying and placing them in a household refrigerator at 1°C-2°C (natural frost temperature), taking them out for observation after freezing for 24 hours, and the total plant rate of frostbite The spraying rate is 40% for the sprayed high-fat film, 80% for the non-sprayed, and 50% of the antifreeze effect; the difference in frostbite rate between the growth point and the true leaf is more obvious, the sprayed high-fat film protection is zero, and the non-sprayed is 12.5.

2.3 Protect melon and fruit seedlings to survive the cold spring

Shaanxi Provincial Cotton Research Institute experimented that spraying high-fat watermelon seedlings after mulching watermelon seedlings can reduce freezing death by 80%. %, increase production by 30%-50%.

2.4 Prevent crops from low temperature and wind chill during the ripening period

In Guangdong Province, it is widely used in late rice to prevent cold dew and wind damage, and the seed setting rate is increased by 10%-25%, the thousand-grain weight is increased by 3%-5%, and the yield per ^hm2 is increased by 10%-25%.

3. Prevention and treatment of diseases

3.1 Diseases of fruit trees

Apple anthracnose control experiment: The School of Plant Protection of China Agricultural University used high-fat film to conduct a control test in Nankou Farm, Beijing, where apple anthracnose is relatively serious, and the control effect was good. The diseased fruit rate was 9.1%, and its control effect was 87.9%.

Apple rust and its crop disease control test: In order to confirm the effect of high-lipid film on disease control as soon as possible, an apple rust control test was carried out on fruit trees in Tiantan Park, Beijing. Chemical agents such as tuzet and chlorothalonil are better. This success shows that the effect of high lipid film on controlling apple anthracnose is reliable. In addition, in order to fully affirm the control effect. It also has a certain "curative" effect on the parasitic powdery mildew; the powdery mildew spots on the leaves in the early stage will deform and dissolve after spraying the high-fat film. Following the success of the above tests, extensive tests and large-scale applications have been carried out in different regions, different crops and different diseases.

Grape anthracnose control test: This test was carried out in Dangshan, Anhui. There were four treatments of conventional chemical pesticides (Bordeaux mixture, tuendazim) and high lipid film biological control blank CK. The control effect of high lipid film was equivalent to that of chemical pesticides. High-fat film control of grape white rot has also been successful, with a control effect of 98%, compared with 97% for conventional chemical pesticides, and 82.2% for ground spraying with high-fat film, which is close to the control effect of plastic film covering the ground.

The test of replacing bagging with high-fat film to prevent and control grape fruit diseases: This test was jointly researched by Changli Fruit Tree Research Institute of Hebei Province and Hebei Banong No. 6 Branch Field. The three control effects of spraying are all above 80%, which is higher than that of the chemical pesticide (tuzet). Use it three times on a large area, and the effect can reach 76%-81%. At the same time, it was observed that the fruit ears close to the ground sprayed with high-fat film did not suffer from diseases, while most of the fruit ears close to the ground bags were diseased. The investment of bagging and spraying high-fat film is also quite different. The former is 41.00 yuan in total, and the latter is 13.75 yuan, which can save 27.25 yuan.

Control test of citrus rootstock seedling blight: the study of the Citrus Research Institute of the Chinese Academy of Agricultural Sciences spraying soil with high-fat film, the disease rate of rootstock seedlings was reduced by 78.4%, and the emergence rate was increased by more than 30%.

Citrus anthracnose: In Zhaoqing City, Guangdong Province in 1988, a trial of high-lipid film was sprayed with 200 times of liquid (for the first time) at the beginning of the disease, and then sprayed again after 10 days, and the control effect could reach 30%-84% again, which could basically suppress the disease.

3.2 Diseases of grain and cotton

Control of Wheat Powdery Mildew and Scab

The test and application results from Sichuan Province, Shanghai City, Beijing City and Hebei Province show that the effect of high lipid film on disease prevention and production increase is remarkable. For example, in the control test of wheat powdery mildew in Sichuan Province, spray 100-200 times of liquid 2 -88.6%-97.6% of the control effect of 3 times. It is significantly higher than the disease prevention effect of lime sulfur mixture (80%) and tuzet (68%), and has the effect of promoting wheat spikelet number, grain number and grain weight. As a result of the test, the number of spikelets in CK area was 17, and the number of grains per spike was 35. The thousand-grain weight is 30.4g; the number of spikelets in the high-fat film area is 24, the number of grains per panicle is 20.5, the number of grains per panicle is 45.5, and the thousand-grain weight is 32.1g; the number of spikelets in the Tuzete plot is 21, the number of grains per panicle is 43.5, and the thousand-grain weight is 30.5 g, The results of the wheat head blight control experiment in Baoshan County, Shanghai: the disease index of the high-fat film, carbendazim and clear water control areas were 1.33, 1.13 and 2.33 respectively, indicating that the disease-prevention effect of the high-fat film was equivalent to carbendazim. The experimental demonstration results of Hanzhong Agricultural Science Institute of Shaanxi Province, Baoji Plant Protection Station of Shaanxi Province, Shaanxi Provincial Plant Protection Institute and Cotton Institute from 1988 to 1990 show that the disease prevention effect and production increase effect of high lipid film are roughly the same as the above situation.

Prevention and control of rice blast: The results of experiments in Zhuanghe County, Liaoning Province, the effect of rice blast is similar or equal to Fuji No. 10 is the best, followed by carbendazim and high lipid film, while thiophanate and Kewensan are worse. In the past two years, Shaanxi Hanzhong Institute of Agricultural Sciences and Guangdong Province have used high-fat film to control rice blast. The effect is similar to or equal to that of Fuji No. 1 and Jinggangmycin, which has a good effect on reducing grain rate and increasing production.

Prevention and control of rice sheath blight: According to the test data of Shaanxi Hanzhong Agricultural Science Institute and Hainan Province, the disease prevention and protection effect of high lipid film is basically the same as that of special pesticides such as tricyclazole and Jinggangmycin. In the control tests of corn purple spot, large and small spot, etc., the effect of high-fat film is also very ideal.

Cotton boll disease prevention and control: Shaanxi Cotton Research Institute conducted a test on the control of rotten bolls with high-fat film. The ground was sprayed with high-fat film once and twice, and the rotten bolls (caused by boll blight) on the lower 1-2 fruit branches and the blank CK In comparison, the control effects are all 100%, and the measures of ground spraying add new content to the prevention and control of diseases, and play the role of enriching physical control methods. According to the results of the anti-rotten boll test conducted by the Shaanxi Cotton Research Institute, among the six treatments of manual peach picking, ground spraying of high-fat film 200 times, 40% ethyl phosphorus aluminum 200 times, and mancozeb 125 times The highest control effect of picking peaches is 100%, and the number of high-fat film under chemical control is 0.53-1.09 less. At the same time, the plot test results show that the control effect of spraying high-fat film on the ground is equivalent to the effect of spraying film on plants, and the average boll per plant is rotten. The number of rotten bolls per plant was 0.6 and 0.4 respectively. The plant and the ground were sprayed with the best control effect. The average number of rotten bolls per plant was 0.1, and the average number of rotten bolls per plant in the clear water control area was 2.7. The control effect is very obvious. Cotton Research Institute of Shaanxi Province cooperated with Liaocheng Agricultural Science Institute of Shandong Province to conduct a large-scale demonstration of high-fat film treatment seeds (soaked seeds). As a result, the root disease rate of seedlings was 24.5%, and that of seedlings without seed dressing was 36.8%. 31.7, the actual harvested number of plants with seed dressing was 45855 plants/hm ² , 23.8 bolls per plant, estimated lint yield per hm ² was 1364.25kg, and the number of plants without seed dressing was 43575 plants/hm ² , with 21.7 bolls per plant. Compared with the high-lipid film seed dressing, the yield-increasing effect was 11.9%. In Jingyang County, Saosong Township demonstration 3.3hm ² sprayed 200 times high-lipid film and no high-lipid film leaf disease index were 25.0% and 30.9%, the control effect reached more than 20%.

3.3 Melon and vegetable diseases

Control of downy mildew of Chinese cabbage: Experiment of control of downy mildew of Chinese cabbage by Vegetable Institute of Zhoukou City, Henan Province, using phosphonium aluminum and water as CK. The control effect of phosphonium aluminum is good, the disease index is 11.8%, the high lipid film is 13.9%; the blank CK is 22.3%, the disease prevention effect of the high lipid film is not as good as phosphonium aluminum, but it has a good effect of increasing production. In the high-lipid film area, the adult plant rate, clean vegetable rate and average weight per plant of Chinese cabbage were higher than those in the B-aluminum and Qingshui CK areas, and the yield was 39% higher than that in CK, and 17% higher than that in the B-aluminum area.

Control of tomato leaf spot: Experiments in Sichuan and Henan have shown that high-fat film can prevent disease and increase production. For example, in Baxian, Chongqing, high-fat film was used to control tomato spot blight for 15 hm ² , and the average control effect was 77 %, while the control effect of mancozeb is 61.9%, and the high lipid film increases the output by 34.6kg-35kg per hm ² , which is very significant.

Melon (watermelon, muskmelon, cucumber) powdery mildew prevention and control: The control of cucumber powdery mildew has been repeated many times. In the experiment in Zhoukou City, Henan Province, the control effect of the high-fat film secondary spraying area was 27.8%, and the yield increased by 5%. The separation effect is 75%, and the yield is increased by 13.8%, and the control effect in the four-spray area is 100%, and the yield is increased by 20%. In Kuitun, Xinjiang, a high-fat film was used to control watermelon and muskmelon (Harney melon) powdery mildew test, the control effect was about 80%, and the yield was increased by 17.3% and 21.7% per ^hm2 ; the sugar content could also be increased to about 2 degrees of sweetness, nearly In recent years, the effect of Guangdong's high-fat film on melons is generally 20%, and the highest can reach 50%.

Prevention and control of flower and plant diseases: the effect of using high-fat film to prevent rose powdery mildew is 86.2%. The disease index of flag vine powdery mildew in the high-fat film control area in June, when the precipitation is concentrated, is 27.9%, while the disease index in CK area is as high as 87.2%. The control effect on cotinus powdery mildew is 68.0%, and the control effect on cotinus powdery mildew is 100%. The research on leaf spot of Euonymus euonymus in Qingdao shows that the control effect of using high-fat film is more than 90%. The high-fat film can reduce environmental pollution and is beneficial Advantages of viewing.

Prevention and control of special crop diseases: Hunan uses high-fat film to prevent and control camellia anthracnose, Jilin province to prevent and control ginseng leaf disease and Guangdong province to prevent and control asparagus stem blight, all of which have significant effects on disease prevention and production increase.

4. Pest control

High-fat film has obvious effect on the control of some small pests and eggs. For example, in the experiment of rice thrips control by Anwei County Plant Protection Institute, there were 3.096 insects per leaf in the pre-prevention seedlings, and only 0.045 insects per leaf after spraying with high-fat film. The pest effect is 98.54%. Sichuan Citrus Research Institute has tested that the high-lipid film has a good effect on controlling citrus yellow spiders and rust ticks. In Beijing, the tests on apples and rose spider mite were all effective. Shaanxi Provincial Cotton Research Institute observed that after spraying two true leaves of cotton seedlings with high-fat film for 7 days, the rate of cotton seedlings with rolled leaves was 5.1%, while that of cotton seedlings with blank CK areas was 40.8%, and the effect was remarkable. Indoor aphid control effect verification, the cotton seedlings were inoculated with aphids first, and then the aphids sprayed with high-fat film all died, and the cotton seedlings sprayed with high-fat film first, and then inoculated with aphids were 31.6% less than CK (no treatment) after 8 days . The anti-freeze damage test was sprayed with high-fat film on the day when the film cotton seedlings were released (April 18), and the investigation was conducted on May 28 (after planting). The rate of broken-headed plants damaged by thrips in the high-lipid film area was 0, while the rate of broken-headed plants damaged by thrips in the CK area without spraying high-lipid film was 7.5%. The control effect was very obvious, and the effect reached 100%.

5. Antiseptic preservation

5.1 Potato seed sprout transportation and preservation

The Agricultural College of Southwest Agricultural University soaked the seed buds in high-fat film and cut them into pieces, then packaged and transported for 15 days. CK (unsoaked) seed bud cuts lost more than 70% of water, while the cuts treated with high lipid film lost 30% of water. To achieve the purpose of antiseptic preservation. 1.5.2 Storage and preservation of citrus fruits: Institute of Plant Protection of Southwest Agricultural University and other units use high-fat film to soak fruit for preservation (penicillium and green mold). Storage 1d). Stacked in the brick ventilated storage, with carbendazim and boric acid plus 2, 4-D and water soaked fruit as CK. The storage test results show that: the average control effect of 50-200 times liquid of high lipid film (4 treatments) is 72.9%, wherein the control effect of 150 times liquid of high lipid film is 83.54%, the control effect of carbendazim is 31.01%, boric acid plus 2 , The control effect of 4-D is 47.04%. The Sichuan test site where the citrus of the Chinese Academy of Agricultural Sciences is located stores about 5000kg of citrus and obtains good results.

5.3 Antiseptic preservation test of green pepper

The College of Horticulture of China Agricultural University treated green peppers with different substances and hormones, 6-7 kinds of drugs, and among 14 kinds of treatments, the fumigation effect of sec-butylammonium was remarkable, and the high-fat film (150 times liquid) had a good antiseptic and fresh-keeping effect; The film plus 2, 4-D treatment is the best, and it has the effect of continuously inhibiting the aging of green peppers ^[1] .

6. Coordinate physiological activities

Tests in Beijing, Liaoning, Shaanxi, Hebei, Hunan and other places have shown that the high-fat film has the function of preventing physiological damage, such as preventing and controlling physiological cracking of Xiaoguoguang apples in the late growth period (the control effect is 87%) and significantly reducing cotton, oil, tea, etc. The general effect of the shedding of vegetative organs (rui, flowers, fruits) is 20%-50%.

7. Improve quality

Experiments in Xinjiang and Liaoning have proved that spraying high-fat film can increase the sugar content of melons by about 2 degrees, and can also prevent bituminous coal disease on the surface of the fruit, resulting in better coloring of the fruit and increasing the output value.

8. Early development

In the large-scale demonstration in Saosong Township, Jingyang County, Shaanxi Province, the number of true leaves was 1-2 more than that of spraying 200 times liquid high-fat film, and the fresh and dry weight of seedlings increased by 10% and 18% respectively. Flowering and boll opening was 7-10 days earlier, and the amount of flowers harvested before the end of August was 10.61% higher than that of spraying with high lipid film, and the yield increased by 8.04%.

9. Instead of mulch

In the demonstration of Shaanxi Cotton Research Institute in Xiqi Village, Dongqi Township, Dali County, the comparison and observation results of mulched cotton, direct seeded cotton sprayed with high-fat film on the ground and direct seeded cotton without spraying high-fat film, the average true leaf of the surveyed plants on May 17 The number, mulch cotton, live spraying with high-fat film and live broadcast without high-fat film were 2.7, 1.95, and 1.55. The growth of cotton seedlings sprayed with high-fat film was equivalent to 35% of the effect of plastic film on cotton growth. September 10 The number of plants and bolls investigated was 14.5, 9.9 and 3.5 for mulched cotton, direct seeding sprayed with high-fat film and direct seeding without spraying high-fat film. The increase rate of mulched cotton and live cotton sprayed with high-fat film is 30.1% and 7.1% respectively compared with direct-broadcast without spraying high-fat film, but the actual economic benefits are the same, (because mulched cotton is 600 yuan more per hm ² than direct-direct sprayed with high-fat film -750 yuan, after subtracting the investment difference of 750 yuan, there is no difference).

In addition, in the cultivation of watermelon plastic film (double film), the effect is also remarkable when the plastic film on the ground is changed to spray high-fat film and not sprayed with high-fat film. According to the survey, the emergence rate of spraying high-fat film is 80%, but not 50% of high-fat film.

10. As a spreading agent

High lipid film is an excellent emulsifier. Its spreading performance is very strong, it is not easy to be washed away by rain, it has the effect of drought resistance and heat protection, and it can be used in combination with other pesticides and fertilizers to have synergistic effects.

The plant ecological protection agent of the invention can prevent pathogens from spreading, invading or changing the physiological activities of parasitic plants, and enhance disease resistance. Limiting the expansion of germs to cause damage, directly or indirectly achieving the purpose of disease prevention and increasing production, can no longer replace heavily polluting chemical pesticides, improve the ecological environment, and have broad application prospects.
