Crop-soil purifying agent and production method thereof

Abstract

The invention relates to a crop-soil purifying agent and a production method thereof, which belongs to the technical field of purification of pesticide and heavy metal residuals in crop soil. The crop-soil purifying agent disclosed by the invention comprises the following raw materials in parts by weight: 5-20 parts of a flos daturae extract, 25-60 parts of a radix glycyrrhizae extract, 3-15 parts of a henbane extract, 6-25 parts of a scutellaria baicalensis extract, 6-25 parts of a radix sophorae flavescentis extract, 4-20 parts of a graperoot extract, and 0.8-2 parts of sodium thiosulfate. According to the invention, specific Chinese herbal extracts and other specific raw materials are combined in specific proportion so as to prepare the soil purifying agent, the purifying agent does not affect the applications of chemical fertilizers and pesticides during the periods of farming and growing, the farming process is not changed, and the crop yield is not affected, even the income increasing of crops can be achieved. After the soil purifying agent disclosed by the invention is used, crops can completely achieve an effect of zero pesticide residue production, and the heavy metal content is also greatly reduced.

Description

Technical field [0001] The present invention involves a soil purification agent and its production method. More specifically, the invention involves a crop soil purification agent and its production method, which belongs to the field of pesticides and heavy metal residue purification technology in crop soil. Background technique [0002] Green environmental protection, safety and health are the pursuit of people.With the development of social development, agriculture to pursue high yields and high income, and to ensure that the crops are not invaded by pests and insect pests, and the use of chemical pesticides in large quantities, coupled with serious industrial pollution, causing pesticides and heavy metal residues in the soil, and then there will be residues in the crops. At the same time, it will also contaminate groundwater and affect people's health. The environment that people depend on survival are constantly threatened. According to relevant departments, about 60%of my co...
