Meanwhile, when the soil contains too much harmful substances and exceeds the self-cleaning capability of the soil, the composition, structure and function of the soil are changed, the microbial activity is inhibited, and the harmful substances or decomposition products thereof gradually accumulate in the soil and pass through the soil, plants and human bodies, or are indirectly absorbed by the human bodies through the soil, water and human bodies, so that great threat is caused to the health of the human bodies.
Soil pollutants can be broadly divided into two general categories, inorganic and organic. The inorganic pollutants mainly comprise acid, alkali, heavy metal, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, and the like. The organic pollutants mainly comprise organic pesticides, phenols, cyanide, petroleum, synthetic detergents, municipal sewage and the like. Therefore, soil amendments are now used to repair soil.
The soil conditioner is also called as a soil conditioner, and is a material which can improve the physical properties of soil, promote the nutrient absorption of crops and does not provide plant nutrients, and the effect principle of the soil conditioner is that soil particles with a lot of years are small, large and stable aggregates are formed, so that the soil conditioner is widely applied to the aspects of preventing soil from erosion, reducing the evaporation or excessive transpiration of soil moisture, saving irrigation water and promoting the healthy growth of plants. The soil conditioner has the functions of preserving soil moisture and increasing temperature, can effectively improve the soil moisture content, increases the soil temperature of a cultivation layer, ensures that the growth period of crops is 2 to 7 days earlier, simultaneously can improve the soil structure, coordinates the relationship among soil water, fertilizer, gas, heat and organisms, prevents water and soil loss, enhances the permeability resistance of channels, inhibits the secondary salinization of the soil, improves the development and utilization of sandy barren lands, and is mainly suitable for areas with insufficient accumulated temperature in the northern arid and semiarid regions of China and the growth period of crops and the soil with poor soil structure, especially for arid lands with serious water shortage, sloping sand lands and saline-alkali lands.
