| 中文摘要: |
| 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。 |
| 英文摘要: |
| The effect of water-solubility Potassium-polyacrylate-polypropyleneacylamine 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. |
