Abstract
The invention provides a soil purifying agent and a preparation method thereof and belongs to the field of a soil conditioner. The soil purifying agent comprises the following raw materials in parts by weight: 25-35 parts of active humic acid, 25-35 parts of medical stone, 15-25 parts of zeolite, 7-13 parts of citric acid, 1-3 parts of trace elements, 1-3 parts of chitin and 1-3 parts of calcium cyanamide. The preparation method comprises the step of mixing the raw material according to parts by weight. The soil purifying agent disclosed by the invention, compared with the prior art, has the advantages of simple production, convenience in application, significant effect and environment friendliness; the soil can be well improved and purified and heavy metals, nitrites and pesticide residues in the soil are degraded and adsorbed to create conditions for the growth and development of the root system; the soil purifying agent has the effects in improving the disease resistance of crops, promoting the growth of crops and increasing both production and income and is quick-acting and high in input-output ratio; the soil purifying agent is suitable for being popularized and applied.
Description
technical field [0001] The invention relates to a soil improver and a preparation method, in particular to a soil purifier and a preparation method. Background technique [0002] With the development and progress of society, agriculture pursues high yield and high income, a large number of chemical fertilizers and pesticides are used, and industrial pollution is serious. The environment on which people live is constantly threatened, especially soil and water resources. According to statistics from relevant departments, about 60% of my country's groundwater is affected. Pollution, about 90% of the soil is polluted, and it is getting worse. [0003] At present, the fertility level of cultivated soil in my country is low, the soil physical and chemical properties are poor, and the low-yield soil with low crop yield accounts for about 30% of the total. Therefore, transforming low-yield soil is of great significance to achieve a balanced increase in agricultural production and acc...
