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。
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 an indoor 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 poly acrylic acid can improve the potassium supplying strength of soil and in high dose, it can raise the buffer capacity of soil potassium.
