Microbial fertilizer for reducing residues of pesticides and heavy metals and preparation method of microbial fertilizer

Abstract

The invention provides a microbial fertilizer for reducing residues of pesticides and heavy metals and a preparation method of the microbial fertilizer. The fertilizer is prepared from the raw materials by weight: 50kg of carboxymethyl starch, 80kg of flavobacterium oryzae fermentation liquid, 100kg of aspergillus glaucus fermentation liquid, 100kg of bacillus subtilis fermentation liquid, 3kg of chitosan, 2kg of nucleotide, 20kg of potassium nitrate, 20kg of dipotassium hydrogen phosphate, 50kg of potassium humate and 1500kg of water. The microbial fertilizer provided by the invention is simple in preparation method and capable of remarkably reducing the residues of heavy metals and pesticides in agricultural products and improving the qualities of the agricultural products.

Description

technical field

[0001] The invention relates to a microbial fertilizer for reducing pesticide and heavy metal residues, which belongs to the new technology of ecological agriculture. Background technique

[0002] With the improvement of living standards, people pay more and more attention to food safety, among which drug residues and heavy metal residues are key indicators and barriers for agricultural products to enter the market and export. In order to prevent pests and diseases in the process of modern agricultural planting, the use of pesticides, fungicides and insecticides is an essential link. Therefore, heavy metals in pesticides, fungicides and pesticides will remain in the soil and agricultural products, causing environmental and food pollution. At present, there is no economical and feasible method on the market to solve the crisis caused by pesticides and heavy metals to the environment and food safety. Traditional methods are costly and will cause secondary pollu...
