摘要
该研究使用的土样是彰武县章古台的风砂土，试验设 4个处理， 3次重复。试验表明，各试筒土样含水量随时间而递减，但应用聚丙烯酰胺处理的土样含水量始终高于对照的，聚丙烯酰胺具有保水和缓释的作用。
The test soil sample adopts the wind－ blown sand soil in Zhangwu county Zhanggutai village and sets up 4 treatments and 3 repetitions. The test showed that the water content in test barrel reduces with time and the water content of soil sample treated by polyacrylamide is higher than undisturbed soil sample.
