Insecticidal organic fertilizer and preparation method thereof

Abstract

The invention discloses insecticidal organic fertilizer which is prepared from the following raw materials in parts by weight: 70-80 parts of ginkgo leaf extraction residue, 30-40 parts of ginkgo leaf extraction waste liquid, 3-5 parts of a synergist, 50-70 parts of plant ash, 80-100 parts of cattle and sheep manure and 5-8 parts of a composite microbial agent. The invention further discloses a preparation method of the insecticidal organic fertilizer. The ginkgo leaf extraction residue and the ginkgo leaf extraction waste liquid have beneficial ingredients with higher nutritional values; environmental pollution can be removed; wastes are changed into valuables; the fertilizer has multiple effects of fertilizing soil, killing pests and improving the soil; and the nuisance free fertilizer is provided for production of green vegetables, fruits and the like. After applied to the soil, the insecticidal organic fertilizer is decomposed by microorganisms in the soil and forms a granular structure with soil particles; the soil can be loosened; the water permeability of the soil is improved; the moisture and fertility preservation ability of the soil is improved; and besides, the decomposed fertilizer can continuously release various nutrients to be absorbed by crops.

Description

Technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and specifically relates to an insecticidal organic fertilizer and a preparation method thereof. Background technique [0002] my country is a large agricultural country. Pesticides and fertilizers play a very important role in agricultural production. With the improvement of people's living standards and health awareness, people attach great importance to the safety of agricultural products, and the demand for pollution-free and green food is increasing year by year. . [0003] The main substance in organic fertilizer is organic matter, and the application of organic fertilizer increases the organic matter content in the soil. Organic matter can improve the physical, chemical, and biological properties of the soil, mature the soil, and improve soil fertility. The proverb in rural China that "the land depends on manure and the seedlings grow by manure" reflects to a certain extent the ...

Problems solved by technology

[0004] At present, the chemical fertilizers used in agriculture and the pesticides used to control diseases and insect pests are mainly chemical preparations. The use of chemical fertilizers and chemical pesticides year after year leads to the development of drug resistance of pests, soil compaction, pollution of water sources, soil and crops, and the decline in the quality of agricultural products. Excessive pesticide residues seriously affect people's physical and mental health and the competitiveness of my country's agricultural products in the international market

[0005] Ginkgo biloba is a large amount of Chinese herbal medicine for both medicine and food. Our country uses 50,000 tons of Ginkgo biloba annually, mainly using the extract obtained by extraction and purification. However, in the production process of Ginkgo biloba extract (GBE), only less than 3% is retained. effective substances, while other organic and inorganic beneficial nutrients are discharged as waste liquid, which will not only pollute the environment, but also cause a great waste of resources, especially the ginkgolic acid produced in the deacidification process has a good Insecticidal and antibacterial, it is a good biological pesticide raw material. Therefore, the rational use of waste generated in the production process of ginkgo biloba extract can produce great economic and environmental benefits
