Problems solved by technology

Continuous cropping and repeated cropping of crops provide a hotbed for the development of pests and diseases. Extensive use of highly toxic pesticides enhances the resistance of pests and diseases while destroying the ecology and increasing pesticide residues. Extensive and irrational use of chemical fertilizers destroys the physical and chemical properties of the soil.

Abstract

The invention relates to a biological pesticide-added fertilizer and a preparation method thereof. The pesticide-added fertilizer is prepared from plant extract residue which comprises one of or a mixture of more than two of lightyellow sophora root extract residue, sophora alopecuroides L. extract residue and black false hellebore extract residue. According to the biological pesticide-added fertilizer, the organic solid waste resources are utilized thoroughly, the production cost is reduced and efficient utilization of the waste resources is realized; in the production process of the biological pesticide-added fertilizer, the environment-friendly effect is achieved, the discharge of wastewater and waste gas can be avoided, and the energy-saving, efficient and low-carbon effects are achieved; the biological pesticide-added fertilizer product is comprehensive and balanced in nutrition without any chemical pesticide and hormone addition, and has a good control effect on a plurality of soil-borne diseases and soil insects; the pesticide-added fertilizer is capable of fundamentally improving the physical and chemical properties of the soil and optimizing the structure of the microflora, and has efficient and lasting fertilizer efficiency and pesticide effect.

Description

technical field [0001] The invention belongs to the field of biomedical fertilizers. In addition to fertilizer effects, it has good effects in terms of drug effects, especially in the field of planting Chinese herbal medicines, preventing and controlling soil-borne diseases in facility vegetable planting, and soil improvement. In particular, it is a medicinal fertilizer and a preparation method. and its application. Background technique [0002] Due to the unreasonable and excessive use of land, there are different degrees of soil compaction and salinization in some areas of our country, resulting in changes in soil physical and chemical properties, and serious soil-borne diseases, especially in the cultivation of vegetables with high added value. Chinese herbal medicine cultivation and other fields. The continuous cropping and repeated cropping of crops provide a hotbed for the development of diseases and insect pests. Extensive use of highly toxic pesticides enhances the ...
