水溶性丙烯酸钾—丙烯酰胺聚合物对土壤水分养分运移的影响

Effect of Potassium-polyacrylate-polypropylene-acylamine Copolymer on increasing available nitrogen of soil

水溶性丙烯酸钾—丙烯酰胺聚合物对土壤水分养分运移的影响进行了实验研究,结果表明:随着时间的延长,水溶性丙烯酸钾—丙烯酰胺聚合物处理在一定时间内能够保持土壤水分在小范围内,使用水溶性丙烯酸钾—丙烯酰胺聚合物对溶于水中的氮素进行吸附后,再注入土壤,使液体中的氮素形成了受约束条件下的扩散,较大幅度地提高了土层的速效氮含量。

The effect of water-solubility Potassium-polyacrylate-polypropylene-acylamine Polymer on increasing the content of available nitrogen of soil was studied. The results showed that the content of soil water diffuse increased with time on different lay with water-solubility Potassium polyacrylate-polypropylene-acylamine Polymer treatment, which retains soil water in small scope; Potassium-polyacrylate-polypropylene-acylamine Copolymer adsorbs the nitrogen dissolving in water, thereafter transfuses it in soil. This lead to that nitrogen in solution diffuses under restricted condition, which greatly increases the content of available nitrogen.
