Problems solved by technology

[0005] According to the above-mentioned current fertilizers that can reduce pesticide residues in my country, they are mainly based on natural extracts and microbial fungi. The main principle is to increase the organic matter and microbial bacteria in the soil to promote microbial activities and improve soil structure. The absorption of nutrients by crops enhances the disease resistance of the crops, but these purposes are all to reduce the amount of pesticides used, thereby reducing the amount of pesticides used

Abstract

The invention belongs to the field of crop fertilizers, and particularly relates to an ecological compound fertilizer for reducing pesticide residue in soil and a preparation method thereof. The main composition of the ecological compound fertilizer disclosed by the invention comprises compound fertilizer, pineapple residue, papaya, grapefruit residue, folium artemisiae argyi, apple residue and lemon residue, and moreover, amino acid trace element complex microelement fertilizer is added. Because the production wastes in the ecological compound fertilizer contain a great deal of protease, the ecological compound fertilizer can promote the decomposition and degradation of organophosphorus in soil, reduce pesticide residue in soil and recover the ecological system of soil; moreover, because the ecological compound fertilizer can provide sufficient organic matters for soil, the ecological compound fertilizer can promote the activity of microorganisms, improve the permeability of soil, promote the nutrient absorption of crops and enhance the disease resistance and stress resistance of crops.

Description

technical field [0001] The invention belongs to the field of fertilizers for crops, and more precisely relates to an ecological compound fertilizer capable of reducing pesticide residues in soil and a preparation method thereof. Background technique [0002] With the vigorous development of the economy, people's demand for food is getting higher and higher. In order to increase food production and meet people's needs, the use of chemical fertilizers and pesticides is essential. However, with the extensive use of chemical fertilizers and pesticides, soil compaction, soil microorganisms and soil organic matter are reduced, which seriously affects the absorption of nutrients by crops, prompting greater use of chemical fertilizers and pesticides, thus forming a vicious circle and destroying the soil. ecological environment, and even caused air pollution and groundwater pollution. [0003] In order to prevent crop diseases and insect pests, the use of pesticides is essential, bu...
