Pesticide residue decomposer and preparation method thereof

Abstract

The invention discloses a pesticide residue decomposer. The pesticide residue decomposer comprises the following components in parts by weight: 0.1-10 parts of grub residue homogenate, 100 parts of biogas slurry, 0.1-10 parts of biogas residue, 0.1-10 parts of deep seawater, 0.1-10 parts of activated carbon, 1-18 parts of chlorella and 500 parts of distilled water. A preparation process of the pesticide residue decomposer is simple and rich in multiple beneficial microorganisms, active enzyme and natural nutrient substances, the residue of harmful substances such as pesticides on the surfaces of fruits and vegetables and in soil can be effectively degraded, the soil is improved, the crop growth is promoted, the crop yield is improved, and the quality of a product is improved.

Description

technical field [0001] The invention belongs to the field of organic fertilizers, and in particular relates to a pesticide residue decomposer and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy and society, soil pollution in my country has become increasingly serious. According to statistics, there are at least 13 million hm 2 ~16 million hm 2 Cultivated land is polluted with pesticides. Every year, various agricultural economic losses caused by soil pollution add up to about 20 billion yuan. At present, my country's pesticide usage has reached 1.3 million tons, which is 2.5 times the world's average level, but the actual utilization rate is less than 30%, and the remaining 70% have polluted the soil and water environment. Pesticide residues lead to a large reduction of beneficial bacteria in the soil. Without beneficial bacteria, the applied organic fertilizer cannot be effectively decompose...

AI Technical Summary

Problems solved by technology

At present, the amount of pesticides used in my country has reached 1.3 million tons, which is 2.5 times the world average level, but the actual utilization rate is less than 30%, and the remaining 70% have caused pollution to the soil and water environment.

Pesticide residues lead to a large reduction of beneficial bacteria in the soil. Without beneficial bacteria, the applied organic fertilizer cannot be effectively decomposed and absorbed. The originally fertile soil becomes barren, the soil self-purification ability is weakened, the soil quality and land productivity are reduced, and the crops are affected. Yield and quality, endangering human health, destroying the sustainable development of agriculture, and even the risk of environmental retaliation

[0003] At present, chemical, physical and biological methods are mainly used to control soil remediation. However, chemical leaching repairs soil based on the principle of similar compatibility, with the help of chemical / biological solvents, to dissolve pollutants, and then remove the solution containing pollutants from the soil. Separation and sewage treatment are carried out by extracting from the medium, and there are problems such as cumbersome procedures, high energy consumption, and easy to cause secondary pollution; and many physical methods cannot be applied due to limitations of equipment conditions and operating techniques.
