Полимеры с высокой впитывающей способностью

(1)SAP can absorb and then keep the rain and irrigative water, which can be released slowly when the crops need water. By this way, it not only guarantees the water needed by the growth of the plant, but also prevents the waste of water by vaporizing, leaking and flowing of water. It can keep the soil wet in a long time and can absorb and release water repeatedly, then is used by the crops slowly. (2)It can ameliorate the soil structure.The repeated shrinking and expanding can make a lot of small holes for soil, enhance the air permeability and water permeability of soil, ameliorate the root environment of the crops, intensify the activity of the microorganism at the root of the plants, and at the same time quicken the decomposition of the organic mineral materials around the root of the soil, promote the growth of the root system and the plants, improve the substrate of the soil and prevent the hardening and salinization of the soil. (3)It can maintain the stability of the molecule structure of all kinds of soil under different climates, and then it can guarantee the ability of the products to absorb, release and keep the water. It also guarantees the repeated usage of the products and prolongs the service period of the products. (4)It can accelerate the growth of the crops, advance the burgeoning rate of seeds, make the young plant come out ahead of time. The SAP can also promote the growth of the root system and make the root system flourish more. (5)It can save the fertilizer and pesticide. If it is used by blending with fertilizer and pesticide, it can keep the fertilizer and release it slowly, at the same time keep the rain and irrigative water. It can prevent the waste of fertilizer and pesticide by vaporizing, leaking and flowing of water, and then improve the usage rate of the fertilizer and pesticide. (6)It is not poisonous, does no harm to the people’s health, and has no side effects. The SAP does not pollute the crops and environment when being used. (7)Even if the SAP is close to the root system and absorbs the water to saturation, it will make the root system of the plant rot and mildew.
