Soil conditioner and water retention agent
Soil degradation mainly includes soil physical degradation, chemical degradation and biological degradation, such as erosion and desertification, compaction and hardening; Soil element imbalance, salinization, alkalizing, secondary salinization and chemical pollution; Low organic matter content and degradation of soil fauna. Soil and soil amendments can be divided into natural amendments, synthetic amendments, natural-synthetic copolymer amendments and biological amendments. They can improve the physical and chemical properties of soil and biological communities, and increase the weight of crops.
Montmorillonite soil amendment is modified and compounded with montmorillonite as the main component. Because montmorillonite has the characteristics of water absorption, expansion, cohesion and cation exchange, it can improve the physical and chemical properties of soil, the utilization rate of fertilizer, and improve and remediate contaminated soil. Montmorillonite soil amendment has the advantages of high cost performance, inorganic mineral components that will transform soil after use, and no secondary pollution.
The water retention agent can absorb tens to nearly a hundred times of salt water or thousands of times of water, and has the ability to repeatedly absorb and release water. This polymer material is widely used in agriculture, forestry and horticulture because of its high water absorption and water retention capacity. Montmorillonite water retention agent is an organic-inorganic composite water retention agent that adsorbs or inserts organic monomers into the montmorillonite layer, and after polymerization and combination, physical crosslinking occurs, and the product has good water retention and salt resistance. At the same time, it overcomes the defects of high production cost of polymer water retaining agent, low gel strength, poor salt resistance, and poor biodegradability after use.
Good water absorption and expansion, can change the proportion of solid, liquid and gas in the soil, so that the soil structure is loose, which not only retains water and fertilizer, but also does not pollute the soil environment;
After modification, soil pollutants can be fixed by physical and chemical adsorption to prevent the migration of pollutants;
The composite water retention agent has strong water absorption capacity, fast water absorption speed, high water retention performance and good water release performance.
