| 摘 要： | 通过温室模拟试验,研究人工土壤,经不同分子量和电荷密度PAM处理后团聚体水稳性的变化状况。试验结果表明,经PAM处理后土壤团聚体水稳性相对对照有了很大的改善,PAM分子量和电荷密度对土壤团聚体水稳性交互作用经历了由极显著到显著再到不显著的过程,并且分子量为1000万电荷密度为30%的PAM改善土壤团聚体水稳性效果最佳,在农业生态建设中有良好的应用前景。

| Abstract: | The water stability of soil cluster is studied after the treatment of different molecular weight and charge density PAM of artificial soil by way of simulation test in the hothouse.The test result indicates that the water stability of soil cluster after the treatment of PAM is ameliorated.The multiple affect of PAM molecular weight and charge density to water stability of soil cluster is a process from particular notable to not notable.The effect of soil cluster water stability ameliorated by PAM that molecular weight being ten millions charge density 30% is optimum. |
