Pesticide decomposing agent and preparation method thereof

Abstract

The invention relates to a pesticide decomposing agent which comprises the following components: 0.1-10 parts by weight of earthworm dung soil, 0.1-10 parts by weight of earthworm residual body homogenate, 0.1-10 parts by weight of deep sea water, 0.1-10 parts by weight of natural ore, 1-18 parts by weight of milk powder and 800 parts by weight of distilled water; a preparation method of the pesticide decomposing agent comprises the steps of separating earthworms which are cultured into adult earthworm period from the earthworm dung soil, weighing the earthworm dung soil, feeding the weighted earthworm dung soil into a fermentation medium, and carrying out aerated fermentation cultivation for 60 days to obtain fermentation liquor which is the pesticide decomposing agent, wherein the fermentation medium comprises 0.1-10 parts by weight of earthworm residual body homogenate, 0.1-10 parts by weight of deep sea water, 0.1-10 parts by weight of natural ore, 1-18 parts by weight of milk powder and 800 parts by weight of distilled water. After the pesticide decomposing agent is adopted, the residue of harmful substances such as pesticide and the like on the surfaces of fruits and vegetables and in the soil can be effectively degraded, the soil is improved, the crop growth is promoted, the crop yield is increased, and the product quality is improved.

Description

Technical field [0001] The invention relates to a pesticide decomposing agent and a preparation method of the pesticide decomposing agent. 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 in the country 2 ~16 million hm 2 Cultivated land is polluted by pesticides. Every year, various agricultural economic losses caused by soil pollution total about 20 billion yuan. At present, the use of pesticides in my country has reached 1.3 million tons, which is 2.5 times the world average, but the actual utilization rate is less than 30%, and the remaining 70% has caused pollution to the soil and water environment. Pesticide residues lead to a large reduction in the beneficial bacteria in the soil. Without beneficial bacteria, the applied organic fertilizers cannot be effectively decomposed and absorbed. The o...

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.
