Description
The organic pesticide fertilizer not only has effective components for preventing and treating crop diseases and insect pests, but also contains organic components required by plant growth, so the organic pesticide fertilizer has the functions of preventing and treating crop diseases and insect pests and promoting crop growth. Such as matrine, allicin, wood (bamboo) vinegar and derris. The registered botanical pesticides contain complex and various components, contain components for killing pests and germs, such as amino acid, tannin, organic acid, alcohol, phenol, quinone trace elements and the like, and the components are usually related to the growth and stress resistance of crops, so the products have the characteristics of stimulating the growth of the crops and improving the immunity of the crops in field application. Recent research and practice shows that the plant-source pesticides show obvious fertilizer effect and yield increase effect. The plant source pesticide with fertilizer effect and yield increasing effect may be also named as organic pesticide fertilizer. (extracted from the Master code of Wangzhongkang, etc. in modern pesticide 100. Wen.), and for example, gingko nut extract soluble agent registered by Xuzhou Jindi biochemistry limited company prevents and treats target cabbage aphid, and the effective component is 24% of ginkgolic acid. Besides the ginkgoic acid with insecticidal and sterilization effects, the ginkgolic acid also contains nutrient components required by plants such as tannin, sugar alcohol, amino acid, phytohormone, trace elements and the like, so that the product not only has the effect of preventing and treating crop diseases and insect pests, but also provides the nutrient components for the crops, stimulates the growth of the crops and improves the stress resistance of the crops in field application. The preparation method comprises extracting semen Ginkgo with 90% ethanol at 80 deg.C, concentrating the extractive solution, recovering ethanol to obtain extract, purifying to obtain mother medicinal material, and emulsifying to obtain water soluble preparation.
The production and popularization of the organic pesticide fertilizer can reduce the usage amount of pesticide and chemical fertilizer, and reduce the amount of the chemical fertilizer and improve the effect. The organic fertilizer plays an active role in replacing the fertilizer, particularly in the action of replacing the fertilizer by the organic fertilizer of fruit, vegetable and tea. The popularization and application of the organic pesticide fertilizer are one of measures for solving the problems of non-point source pollution and food safety.
Although many registered plant-derived pesticides have the characteristics of organic pesticide fertilizers at present, the application of the plant-derived pesticides still accounts for a small proportion in agricultural production, and the reason is that a large amount of natural resources, manpower and financial resources are consumed for producing the organic pesticide fertilizers, so that the cost for producing the organic pesticide fertilizers is increased, the price of the organic pesticide fertilizers is increased, and the investment of agricultural production is increased. For example, matrine production requires planting sophora flavescens, occupies cultivated land, and consumes certain manpower and financial resources. The organic pesticide fertilizer produced by using the sticky paste-shaped waste residue for producing the ginkgo ketone changes the sticky paste-shaped waste residue into valuable, does not need to consume natural resources and solvent for extraction, and can save two links of planting and extraction, thereby saving the fund, manpower and time. The organic pesticide fertilizer prepared by using the sticky paste-shaped waste residue for producing the ginkgones has higher content of ginkgolic acid, can kill insects such as aphids, thrips, cabbage caterpillars, plant hoppers and the like, can also prevent and treat fungal diseases such as cucumber downy mildew, tomato gray mold, rice sheath blight and the like, and has high prevention and treatment effect. The high-efficiency insect prevention and treatment are beyond the reach of other pesticides. The organic pesticide fertilizer contains rich chlorophyllin, sugar alcohol, amino acid, vitamins, carotene, various trace elements and the like, provides rich nutrient elements for crops, is efficient and quick-acting, promotes the growth of the crops to be accelerated, stimulates the crops to generate stress resistance, and enhances the immunity.
The invention aims to utilize the sticky paste-shaped waste residue generated in the production of the ginkgone to prepare the organic pesticide fertilizer which has no toxic or side effect, can efficiently and broadly prevent and treat crop diseases and insect pests, can provide rich nutrient components for crops, promotes the growth of the crops and improves the stress resistance of the crops.
The present invention is thus achieved.
1. And (4) extracting. Adding ethanol (more than 90%) into the pasty waste residue according to the proportion that the pasty waste residue and the ethanol (more than 90%) are = 1: 5, heating to 80 ℃, stirring uniformly, and then continuing stirring for 10 minutes.
2. And (5) filtering. Filtering with 80 mesh filter screen, and filtering the extractive solution.
3. And (5) concentrating. Concentrating the filtrate at 85 deg.C until no alcohol exists, recovering ethanol smell, and collecting the concentrated solution.
4. Preparing the alkali ethanol. Adding potassium hydroxide into ethanol according to the proportion of (90%) ethanol to potassium hydroxide = 10: 1.1 to prepare saturated potassium hydroxide ethanol, namely alkaline ethanol.
5. And (4) saponification reaction. Adding alkaline ethanol at 80 deg.C according to the ratio of concentrated solution to alkaline ethanol = 5: 1, stirring, and maintaining for 5-10 min.
6. And (4) emulsifying. Adding surfactant heated to 80 deg.C into saponification solution heated to 80 deg.C at 80 deg.C according to the ratio of concentrated solution to surfactant = 4: 1, stirring well, and maintaining at 80 deg.C for 10 min.
7. And (4) filtering. The emulsion was filtered through a 100 mesh screen.
The prior other organic pesticide fertilizer production technologies have the following advantages:
1. the raw materials for producing the organic pesticide fertilizer are sticky waste residues for producing the ginkgone, the gingko is not required to be planted, natural resources are not consumed, the process of extracting the gingko leaves is omitted, and the solvent, manpower and time are saved, so that the production cost of the organic pesticide fertilizer is low.
2. The organic pesticide fertilizer prepared by the invention can be used for broad-spectrum and high-efficiency prevention and control of crop pests and fungal diseases, has no toxic or side effect, can be used as an irrigation fertilizer and a leaf fertilizer, has high-efficiency and quick-acting effects, promotes the growth of crops, and improves the stress resistance.
3. The process is simple and easy to operate. No waste water and waste gas are discharged in the production process, and no pollution is caused to the environment.
4. Is convenient for farmers to use. The organic pesticide fertilizer provided by the invention is applied once by farmers, has two effects, can prevent and treat plant diseases and insect pests, can increase nutrient components of crops, and promotes the growth of crops. The peasant saves money, labor and time and is convenient to use.
