Abstract
A biological preparation for reducing organophosphorus pesticide residue and promoting crop growth is prepared by concentrating waste liquid containing tea polysaccharide obtained by processing tea polyphenols and caffeine with tea leaves or brown algae oligosaccharide obtained by processing herba Zosterae Marinae with mannitol and sodium alginate, adjusting pH value directly or by adding rare earth, concentrating to obtain liquid foliar fertilizer, and drying to obtain solid foliar fertilizer; or dissolving solid tea polysaccharide, herba Zosterae Marinae waste or dextran, and adding agricultural rare earth nitrate. The biological preparation prepared by the method can ensure that the degradation rate of the organophosphorus pesticide in the crops is more than 80 percent after several days, and the crop yield is increased by 3-20 percent. The biological preparation is a natural preparation or contains a small amount of rare earth, so that the use amount of the rare earth is greatly reduced, the agricultural safety of the rare earth is improved, and rich tea and brown algae resources in China are fully utilized at a high value. And the method has the advantages of no waste gas, environmental pollution caused by waste water, easily available raw materials, simple process and low investment, and is suitable for the technical improvement requirement of brown algae processing enterprises for improving benefits.
Description
Technical field
The present invention relates to the short plant growth biologic product preparation method of a kind of decreasing organic phosphorous pesticide residue.
Background technology
China has a large population in a small area, and how to guarantee that size of food safety and quality safety are long-term and difficult task.With regard to plant resource food, no matter be large grain-production, or the production of vegetable and fruit, their growth busy season is also mostly to be that the busy season takes place in insect pest.Present stage, the peasant also needed to use the chemical pesticide control insect pest in order to improve their output and quality.Along with the complete prohibition use and the pyrethroid pesticide of organo-chlorine pesticide easily makes insect develop immunity to drugs, organophosphorous pesticide has accounted for 70% of insecticide total amount at present.But long-term large-scale production and use organophosphorous pesticide not only causes severe contamination to environment, residual in food and feed people and cultivated animals is also seriously influenced.And the superseded use or reach in food hygienic standard of construction, biopesticide and organophosphorous pesticide development of substitutes and some organophosphorous pesticide of carrying out research, the pollution-free food production base of transgenic pest-resistant, disease-resistant crop does not have and detects requirement etc. and all need very strong science and technology and funds support, apply from developing to as a kind of agricultural chemicals, need multi-disciplinary cooperations such as chemistry, agronomy, medical science and environment, go through 10 surplus year.According to the national conditions of China, present stage is the use of impossible total ban organophosphorous pesticide also.Therefore, develop a kind of can the degraded and do the residual of the interior organophosphorous pesticide of object, the biologic product that can promote plant growth again is current and presses for from now on.
Rare earth application is China's initiative, and has become one of major measure of agricultural production and income.At present relevant RE microbial fertilizer (as " Chang Le ") and relevant patent (as: 96109036.7, manufacture method of solvay-type RE microbial fertilizer and products thereof; 96117083.2, serial compound rare-earth trace element fertilizer and production method thereof; 98103155.2, a kind of solubility compound powder as fertile medicine) and the main purpose of its developments such as other foliage fertilizers and biologic product be to promote plant growth and raising quality, and existing promotion plant growth has the product for agriculture of decreasing organic phosphorous agricultural chemicals to have not yet to see patent report.We find to the physiological and biochemical research of rare earth, sea-tangle and tealeaves isoreactivity composition the time, natural tea polysaccharide and algal polysaccharide are combined with rare earth element, this natural malt sugar soil compound and tea polysaccharide, brown alga oligose class and glucan are that part and rare earth element ligand complex are prepared the polysaccharide RE composite, and the phosphide key is all had very strong splitting action.Organophosphorous pesticide contains the phosphide key mostly, and therefore, the polysaccharide RE composite has degradation to organophosphorous pesticide theoretically, but has not yet to see the patent of invention report.
Summary of the invention
One of purpose of the present invention is to overcome the deficiency of prior art, and the preparation method of the short plant growth biologic product of a kind of decreasing organic phosphorous pesticide residue is provided.
Another object of the present invention is to promote the higher value application of tealeaves and brown alga industrial enterprise discarded object.
The preparation method 1: do not add the preparation method that rare earth directly utilizes tealeaves and brown alga industrial enterprise discarded object (often including rare earth usually): A, directly utilize contain tea polysaccharide waste liquid and B behind Tea Processing Tea Polyphenols and the caffeine to utilize the brown alga oligose waste liquid that contains behind sea-tangle processing mannitol, the sodium alginate to concentrate the back and regulate pH value to 4～7, filter, and further concentrate liquid biologic product, dry solid-state biologic product
The preparation method 2: add the preparation method that rare earth utilizes tealeaves or brown alga industrial enterprise discarded object: A, utilize behind Tea Processing Tea Polyphenols and the caffeine contain the tea polysaccharide waste liquid and B utilizes sea-tangle processing mannitol, contain the brown alga oligose waste liquid behind the sodium alginate, after concentrating, add in advance with the rare earth of dilute nitric acid dissolution or directly use agricultural nitric acid rare earth, the percentage that rare earth adding quantity accounts for tea polysaccharide or sea-tangle discarded object weight is controlled at 0.00%～0.5%, react 5～24h down at 10～35 ℃, transfer reacting liquid pH value to 4～7 with acid or alkali, filtering and concentrating gets liquid biologic product, or dry solid-state biologic product.
The preparation method 3: add in advance solid-state tea polysaccharide or the sea-tangle discarded object dissolving back that contains brown alga oligose with the rare earth of dilute nitric acid dissolution or directly use agricultural nitric acid rare earth, the percentage that rare earth adding quantity accounts for tea polysaccharide or sea-tangle discarded object weight is controlled at 0.00%～0.5%, react 5～24h down at 10～35 ℃, transfer reactant liquor pH value to 4～7, filter, concentrate liquid biologic product, or dry solid-state biologic product.
With the biologic product of said method processing, application can make organophosphorous pesticide reach more than 80% at degradation rate after a couple of days on the crop that has sprayed organophosphorous pesticide, and the crop yield rate is 3～20%, and the crop yield probability is about 85%.In addition, this biologic product is a kind of natural medicine or contains more a spot of rare earth, thereby not only greatly reduced the usage amount of rare earth, improved the safety of rare earth application, and made the tealeaves of China's abundant and brown alga resource obtain abundant higher value application.
The present invention also has production process not have distinguishing features such as waste gas, contaminated wastewater environment, raw material are easy to get, technology is simple, investment is very little, therefore the technological transformation needs that not only are fit to existing Tea Polyphenols factory and brown alga processing enterprise, improve its benefit, and can produce and be applicable in rural area medium-sized and small enterprises, be a kind of new technology that current pollution-free food production presses for.
