Description
Technical Field
The invention relates to the field of agricultural fertilizers, in particular to a fertilizer for planting broccoli, which can reduce plant diseases and insect pests.
Background
Broccoli, also known as cauliflower, is a 1-2 year old herbaceous plant. The broccoli is rich in nutrition, contains protein, sugar, fat, vitamins and carotene, has the nutritional ingredients at the head of similar vegetables, and is known as 'vegetable crown'.
The broccoli is suitable for being planted on loam and sandy loam which are good in irrigation and drainage, deep in plough layer, loose and fertile in soil and strong in water and fertility preservation, and needs sufficient fertilizer in the whole growth process, wherein the nitrogen-phosphorus-potassium ratio of the broccoli is 14: 5: and 8, in the growth process of the flower ball, the broccoli has more requirements on trace elements such as boron, molybdenum, magnesium and the like, so that the yield and the quality can be obviously improved by applying a proper trace element foliar fertilizer before budding.
1. Illumination: the requirements of broccoli on illumination are not very strict, but sufficient illumination is favored in the growth process, the plants grow strongly when the illumination is sufficient, strong nutriments can be formed, photosynthesis and nutrient accumulation are facilitated, the flower balls are compact and compact, the color is bright green, the quality is good, and the growth and development of the broccoli are not facilitated due to excessively strong sunlight in summer.
2. Temperature: in the range of 5-20 deg.C, the higher the temperature, the faster the growth and development of broccoli. The optimum germination temperature is 20-25 ℃, and the optimum growth temperature in the seedling stage is 15-20 ℃. The broccoli has strong cold resistance and heat resistance, the growth temperature in the rosette stage is 20-22 ℃, the development temperature of the curd is 15-18 ℃, the quality of the curd is easy to deteriorate when the temperature is higher than 25 ℃, but the curd can still slowly grow at the low temperature of 5 ℃ or even below as long as the curd is not frozen.
The temperature requirements for vernalization completion of different varieties and different seedling ages are greatly different, so that the selection of varieties in annual cultivation is very important.
3. Water content: the water demand of the broccoli is large in the whole growth process, particularly, the broccoli cannot lack water in the vigorous growth period and the ball formation period, and the yield is reduced even if the broccoli is drought for a short time. Diseases such as black rot, black spot and the like are easily caused by heavy rain in the seedling stage or overhigh soil humidity. The soil humidity in the formation period of the flower ball can meet the growth requirement only when the field water capacity is about 70-80%.
4. Soil: the broccoli has low requirements on soil conditions, but if the broccoli is too lean, the plant is dysplastic, the yield and the quality are low, and if the soil is too fertile, the flower buds are loose and the flower moss is hollow. The broccoli is suitable for being planted on loam and sandy loam which are good in irrigation and drainage, deep in plough layer, loose and fertile in soil and strong in water retention and fertility preservation. The pH value of the soil is adapted to 5.5-8, but 6 is the best. The broccoli needs sufficient fertilizer in the whole growth process, and the N, P, K ratio of the broccoli is 14: 5: 8. the nitrogen requirement is relatively high in the seedling stage, and the P, K requirement is relatively increased after flower buds begin to differentiate.
However, in the field of broccoli planting, different fertilizers are continuously researched to supplement nutrient elements lacking in broccoli, and the influence on illumination, moisture, temperature and the like of the broccoli after fertilization, particularly after foliar fertilizer application, is ignored, and the influence on pest and disease resistance of the broccoli after fertilizer application is not concerned.
Disclosure of Invention
The invention aims to provide a fertilizer for planting broccoli capable of reducing plant diseases and insect pests, and aims to solve the problems that after foliar fertilizer is applied in the prior art, factors such as illumination, moisture and temperature required by growth of broccoli are adversely affected, and improvement of disease and insect pest resistance of products cannot be realized.
In order to achieve the purpose, the invention provides the following technical scheme:
a fertilizer for broccoli planting capable of reducing plant diseases and insect pests comprises the following raw materials in percentage by species:
100 portions of water, 20 to 30 portions of sepiolite, 10 to 15 portions of nano silicon dioxide, 1 to 3 portions of nano titanium dioxide, 1 to 3 portions of graphene oxide, 1 to 3 portions of bacterial cellulose, 0.1 to 0.5 portion of sodium polystyrene sulfonate and 0.1 to 0.5 portion of microcrystalline cellulose.
The technical scheme of the invention introduces sepiolite, nano silicon dioxide, nano titanium dioxide, graphene oxide, bacterial cellulose and microcrystalline cellulose, firstly, the molecular structures of the bacterial cellulose and the microcrystalline cellulose also have a large amount of active polar functional groups such as hydroxyl, when the product is sprayed on the surface of broccoli, the product can be well compatible with the surface of broccoli, and a gelled structure is formed on the surface, meanwhile, the sepiolite, the nano silicon dioxide, the nano titanium dioxide and the graphene oxide all contain polar functional groups such as hydroxyl, carboxyl and the like which can form hydrogen bond acting force with the gelled structure, so that an organic-inorganic composite gel layer is constructed on the surface of the broccoli, the gel layer is transparent and light, the normal photosynthesis of the broccoli can not be blocked, and due to the existence of sodium polystyrene sulfonate, a benzene ring can be mutually attracted and adsorbed with a conjugated region of the graphene oxide, the graphene oxide layers are mutually repelled due to the same negative charges, so that the interlayer spacing is widened, and a diffusion channel of air and water vapor is formed in the composite gel layer, so that the normal respiration of the broccoli cannot be influenced; in addition, the organic-inorganic composite gel layer keeps good mechanical strength, and the effect of plant diseases and insect pests on broccoli can be effectively prevented; the free radicals generated by the nano titanium dioxide under the action of sunlight can also have good effect of resisting microorganisms such as bacteria and the like; with the prolonging of the service life of the product, the bacterial cellulose and the microcrystalline cellulose are gradually degraded and directly absorbed by broccoli as nutrient components, thereby playing a role in fertilizer efficiency; moreover, the composite gel layer can play a good heat preservation and insulation effect, the plants can be maintained at a relatively high temperature at night, the plant metabolism reduction caused by high temperature can be avoided in the daytime, the excessive transpiration effect is realized, an independent small greenhouse is formed, and the broccoli can grow rapidly.
Further, the modified polyallylamine aqueous solution also comprises polyallylamine with the water mass of 1-5%.
The technical scheme of the invention introduces polyallylamine which can absorb carbon dioxide generated by plant respiration at night, and the carbon dioxide is released after sunlight irradiation in the day and can be directly used as nutrient for photosynthesis to play a good regulating role.
Further, the sepiolite is sepiolite in which magnesium ions in the framework are replaced by hydrogen ions.
Further, the sepiolite is sepiolite in which magnesium ions in the framework are completely replaced by hydrogen ions.
According to the technical scheme, the sepiolite with the magnesium ions replaced by the hydrogen ions in the framework is utilized, and Si-O functional groups are converted into Si-OH after the sepiolite is replaced, so that the hydrogen bond acting force between the sepiolite and other components is enhanced, the mechanical performance of the gel is further improved, and the attack of insect pests is avoided.
Furthermore, the humic acid fertilizer also comprises humic acid with the water mass of 1-10%.
Further, the microcrystalline cellulose is microcrystalline cellulose with the limiting degree of polymerization of 100-150.
Further, the microcrystalline cellulose is microcrystalline cellulose with the limiting degree of polymerization of 120-150.
Further, the water-soluble chitosan-chitosan composite material also comprises chitosan with the water mass of 1-5%.
Further, the chitosan is chitosan with deacetylation degree of 85-95%.
Further, the chitosan is chitosan with deacetylation degree of 90-95%.
The invention introduces chitosan and further limits the deacetylation degree of the chitosan so as to control the solubility of the chitosan in water and the strength of formed gel, so that the product has good affinity and insect resistance.
