Pesticide residue degradation nutrient solution and preparation method thereof

Abstract

The invention discloses a pesticide residue degradation nutrient solution which comprises the following substance components in percentage: 37% of fertilizer, 4% of bacillus subtilis, 3% of white rot fungi, 5% of aspergillus, 4% of photosynthetic bacteria and 45% of underground water. The invention also discloses a preparation method of the pesticide residue degradation nutrient solution. The preparation method comprises the following steps: S1, calculating the weight of the required fertilizer, bacillus subtilis, white rot fungi, aspergillus, photosynthetic bacteria and underground water, and weighing for later use; s2, placing the underground water in a reaction kettle, heating the underground water in the reaction kettle, and keeping the underground water at a constant temperature; and S3, crushing the fertilizer. Fertilizer of the pesticide residue degradation nutrient solution can provide nutritional ingredients for crops and is beneficial to growth of the crops, meanwhile, bacillus subtilis, white rot fungi, aspergillus and photosynthetic bacteria are added into the nutrient solution, pesticides such as trichlorfon and prometryn can be degraded, and guarantee is provided for health of people.

Description

technical field [0001] The present invention relates to the technical field of nutrient solution, in particular to a kind of pesticide residue degradation nutrient solution and preparation method thereof. Background technique [0002] Chemical pesticides play a huge role in the prevention and control of crop diseases, pests and weeds and the elimination of health pests and diseases due to their advantages of quick effect, wide control spectrum, stable nature, convenient storage and transportation, and low price. Side effects such as environmental pollution, killing of natural enemies, and drug resistance from pests and weeds have led to adverse consequences such as increased pesticide residues, decreased soil fertility, and decreased quality of agricultural products. Especially, pesticide residues with high toxicity and stable properties have a long life and are not easily degraded. health poses a serious threat. SUMMARY OF THE INVENTION [0003] The purpose of the pres...

[0002] Chemical pesticides play a huge role in the prevention and control of crop diseases, insect pests and weeds, as well as sanitary pests and diseases due to their advantages of quick effect, wide control spectrum, stable properties, convenient storage and transportation, and low price. However, the extensive use of pesticides also brings Side effects such as environmental pollution, killing natural enemies, and resistance to pests and weeds have led to adverse consequences such as increased pesticide residues, decreased soil fertility, and decreased quality of agricultural products. In particular, pesticides with high toxicity and stable properties have a long residue period and are not easy to degrade. serious threat to health
