摘要
[目的]为了研究有机无机复合保水剂在沙土中的实际保水效果和对沙土理化性质的影响。[方法]在人工气候箱中模拟苛刻荒漠条件,考察不同时间段和不同含量(0.10%、0.25%、0.50%、1.00%)有机无机复合保水剂在沙土中的保水性能和对沙土的改良作用。[结果]复合保水剂具有良好的保水性,经过18次反复使用后,复合保水剂改良沙土效果明显。[结论]复合保水剂适用于沙土中。
[ Objective] The effects of the organic-inorganic superabsorbent composite on water absorbency and physicochemical properties of sandy soil were investigated. [ Method] The water absorbency in sandy soil containing various concentration （0.10% , 0.25% , 0.50% and 1.00% ） of superabsorbent composites was investigated in an artificial climate chest. [ Result] Superabsorbent composites had a good water absorbency maintained and improved the physicochemieal properties of sandy soil after reuse 18 times. [ Conclusion] The superabsorbent composite as water-managing materials had a good property in sandy soil.
