Problems solved by technology

For example, the waste gas discharged from non-ferrous metal smelters contains heavy metals such as chromium, lead, copper, and cadmium, which pollutes the nearby soil; factories that produce phosphate fertilizers and fluorides cause dust pollution and fluorine pollution to the nearby soil
3. Chemical fertilizers: The application of chemical fertilizers is an important measure to increase agricultural production, but unreasonable use can also cause soil pollution
Long-term large-scale use of nitrogen fertilizer will destroy the soil structure, cause soil compaction, deteriorate biological properties, and affect the yield and quality of crops
Excessive use of nitrat

Abstract

The invention discloses a soil conditioner for treating farmland pollutants and a preparation method of the soil conditioner. The soil conditioner is prepared from soy bean meal, peat humic acid, toosendanin, magnesium oxide, potassium nitrate, zinc sulfate, slow-release boron, cortex cinnamomi, a microbial agent, sodium alginate and traditional Chinese medicine raw materials, wherein the traditional Chinese medicine raw materials comprise aizoon stonecrop herb, common achyranthes herb, blumea balsamifera, root and tuber of dysosma majorensis, quercus fabri hance, fruit of embelia oblongifoliaand root of vitex negundo, and the soil conditioner is prepared by selecting, impurity removing, grinding, drying and uniform mixing. By increase of pH of soil, mobility of heavy metal in soil is reduced, the immobilization effect is realized, and the soil conditioner has functions of improving physical and chemical properties of the soil, improving soil fertility, increasing crop yield and improving crop quality.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil conditioner for repairing farmland pollutants and a preparation method thereof. Background technique [0002] Soil refers to the loose surface layer on the land surface that is fertile and capable of growing plants, and its thickness is generally about 2 m. Soil not only provides mechanical support for plant growth, but also provides fertility elements such as water, fertilizer, air, and heat for plant growth and development. Due to the rapid growth of population and the rapid development of industry, solid wastes are continuously stacked and dumped on the soil surface, harmful waste water is continuously infiltrated into the soil, and harmful gases and floating dust in the atmosphere are also continuously falling into the soil with rainwater, resulting in soil pollution. All substances that hinder the normal function of the soil, reduce the yield and quality of ...
