| 摘 要： | 通过室内模拟试验,研究了关中(?)土经PAM处理后,土壤中氮、磷、钾的淋溶状况,试验结果表明,经PAM处理后,土壤淋溶液中N,P,K累积量分别较对照减少了42.40％,43.85％和68.19％。同时,不同浓度PAM的试验结果发现,增加PAM浓度能使土壤淋溶液中N,P,K累积量进一步减少。

| Abstract: | The effect of PAM on the eluviations of N, P and K in the soil is studied. The results showed that the content of N, P and K in the soil soluble liquid decreased strikingly. The accumulative quantities of the N, P and K in soil soluble liquid decreased by 42. 40%, 43. 85% and 68. 19% compared with the accumulative quantity of control. In addition, the accumulative quantity N, P and K in the soil soluble liquid decreased further when the concentration of PAM increased. |
