Problems solved by technology

However, the extensive use of pesticides has also brought about environmental pollution, killing natural enemies and producing resistance to pests and weeds, resulting in increased pesticide residues, decreased soil fertility, and decreased quality of agricultural products. Pesticides are long-term and non-degradable pesticides, which pose a serious threat to human health. Soil safety and agricultural product safety have become hot issues of concern

Embodiment 1

[0025] A soil conditioner that uses microorganisms to degrade pesticides in soil is composed of the following raw materials in parts by mass: organic fermented fertilizer composed of poultry manure, humic acid, bagasse, and peanut meal with a mass ratio of 20:5:8:3 180 parts, 4 parts of micro-fertilizer composed of copper sulfate, borax, ammonium molybdate, manganese sulfate and ferrous sulfate in equal mass ratio, 3 parts of bentonite, 6 parts of phosphate rock powder, 5 parts of amino acid, 0.8 part of microbial flora Composition; Wherein, the mass percent of each bacterium in the microbial flora is Pseudomonas fluorescens 20%, Rhodopseudomonas palustris 15%, Faecal Alcaligenes 5%, Pseudomonas putida 7%, Bacillus licheniformis 12%, Bacillus sphaericus 10%, Bacillus megaterium 13%, Bacillus cereus 18%.

Embodiment 2

[0027] A soil conditioner that uses microorganisms to degrade pesticides in soil is composed of the following raw materials in parts by mass: organic fermented fertilizer composed of poultry manure, humic acid, bagasse, and peanut meal with a mass ratio of 20:5:8:3 150 parts, 4 parts of micro-fertilizer composed of copper chloride, boric acid, sodium molybdate, manganese carbonate, ferrous sulfate in equal mass ratio, 4 parts of bentonite, 6 parts of phosphate rock powder, 4 parts of amino acid, 0.5 part of microbial flora Composition; Wherein, the mass percent of each bacterium in the microbial flora is Pseudomonas fluorescens 30%, Rhodopseudomonas palustris 12%, Faecal Alcaligenes 8%, Pseudomonas putida 10%, Bacillus licheniformis 10%, Bacillus sphaericus 10%, Bacillus megaterium 5%, Bacillus cereus 15%.

Embodiment 3

Abstract

The invention discloses a soil conditioner for degrading pesticides in soil with microorganisms. The soil conditioner is prepared from, by mass, 100-200 parts of organic fermented manure, 3-5 parts of trace fertilizer, 2-5 parts of bentonite, 5-7 parts of phosphate rock powder, 3-5 parts of amino acid and 0.1-1 part of microbial flora, wherein the microbial flora is composed of pseudomonas fluorescens, rhodopseudomonas palustris, alcaligenes faecalis, pseudomonas putida, bacillus licheniformis, spherical lysine bacillus, bacillus subtilis and bacillus cereus. The soil conditioner is prepared by compounding various microbial strains, the organic fermented manure, the trace fertilizer, amino acid, the bentonite and the phosphate rock powder, and can degrade the chemical pesticides in the soil, such as organic phosphorus pesticides, heterocyclic pesticides, phenol pesticides and aromatic pesticides, and remedy the pesticide-contaminated soil.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improver which utilizes microorganisms to degrade pesticides in soil. Background technique [0002] Chemical pesticides play a huge role in the prevention and control of crop diseases, insect pests and weeds to eliminate sanitary pests and diseases, and promote the development of modern agriculture due to their advantages of quick effect, control spectrum, stable properties, convenient transportation, and low price. Of course, the extensive use of pesticides has also brought about environmental pollution, killing natural enemies, and side effects of resistance to pests and weeds, resulting in increased pesticide residues, decreased soil fertility, and decreased quality of agricultural products. Pesticides, which have a long lifespan and are not easy to degrade, pose a serious threat to human health. Soil safety and agricultural product safety have become hot issue...
