摘要

通过室内模拟试验

研究了关中塿土经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

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

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.
