摘要：

通过盆栽实验，探究秸秆、膨润土和PAM的共同作用对砂质土壤有机质和阳离子交换量的影响，寻找改良剂的最佳配方，为秸秆沙质土壤改良剂与产业化示范提供数据基础。结果表明，秸秆、膨润土和PAM共同作用显著提高了沙质土的有机质的含量、腐殖化系数以及阳离子交换量。当秸秆预产物、膨润土和PAM的比例按900：100：30，施加量为10g/kg时，处理60天后达到了最好的效果，使沙质土有机质、腐殖质含量以及阳离子交换量分别较对照提高了28%、25%、36%。

Abstract:

In order to provide the data foundation for the demonstration of the straw stalk sandy soil ameliorating materials, the pot experiments used to inquire into the interacted function of the straw stalk and Bentonite and PAM (Polyacrylamide) were designed. The results indicate that it obviously raises the content of the soil cation exchange capacity and the contents of the soil organic matter and humus. The best formula respectively improves the content of the soil cation exchange capacity and the contents of the soil organic matter and humus by 36%, 28%, 25% compared with the contrast in 60 days.
