| 摘 要： | 选用云母粉和丙烯酸单体为原料,通过交联合成方式,合成了一种新型的保(吸)水材料,在探讨了其保水特征的基础上,采用室内培养试验,进一步分析了其对土壤供钾状况的影响.结果表明,云母粉聚丙烯酸交联物具有很好的保(吸)水特性,尤其具有很好的吸含盐溶液的能力;将其施入土壤后在低剂量时就可以明显提高土壤的供钾强度,并在高剂量时提高土壤钾素的缓冲容量.

| Abstract: | In this paper,mica powder and acrylic monomer were selected as raw material and made it into a new water absorption polymer.To explore the basic water absorbing characteristic,its influences on the potassium supply of soil was studied by anindo or training experiment.Results showed that the absorbing char-acteristics of the cross-linked substance of mica powder and poly acrylic acid is desirable,especially the strong saline absorption.When applying it into soil in low dose,the cross-linked substance of mica powder and polyacrylic acid can improve the potassium supplying strength of soil and in high dose,it can raise the buffer capacity of soil potassium. |

| Keywords: | cross-linked substance of mica powder and poly acrylic acid water absorbing characteristics state of potassium supplying |
