摘　　要：彭阳县地处黄土丘陵半干旱地区,十年九旱,春旱或春夏连旱时有发生,造成农作物减产。抗旱保水剂具有保温、有效抑制水分蒸发和提高肥料利用率等作用。为验证不同抗旱保水剂在彭阳县的使用效果,选择市面上4种抗旱保水剂进行对比试验。研究结果表明:常规全膜覆盖+施可润保水剂处理产量最高,达12546.1 kg/hm^(2)(P<0.01),对照(不覆膜)产量最低,为9545.9 kg/hm^(2);常规全膜覆盖+耕田乐保水剂处理较对照(不覆膜)、常规半膜覆盖、常规全膜覆盖分别增产25.7%、14.8%、4.49%(P<0.01);常规半膜覆盖+施可润保水剂处理较处理对照和常规半膜覆盖分别增产19.68%和9.28%(P<0.01);常规半膜覆盖+山东润涵水量子和常规半膜覆盖+海瑞达保水剂处理较常规半膜覆盖处理增产效果不明显(P<0.01)。Pengyang County is located in the semi-arid loess hilly areas.Nine droughts in ten years,spring droughts or springsummer droughtsoccured from time to time,resulting in reduced crop yields.The use of drought-resistant and water-absorbent polymer can effectively inhibit water evaporation,have good thermal insulation properties and improve fertilizer utilization.In order to verify the effect of using droughtresistant and water-absorbent polymer in our county,four kinds of drought-resistant and water-absorbent polymer on the market were selected for comparative experiments,the results of the study showed that the conventional full film coverage+Shikerun water retaining agent treatment had the highest yield,12546.1 kg/hm^(2)(P<0.01),while the control yield is the lowest at 9545.9 kg/hm^(2);Compared with the control,conventional half-film coverage,and conventional fullfilm coverage,the conventional full film coverage+Gengtianle water retention agent treatment increased production by 25.7%,14.8%,and 4.49%respectively(P<0.01);The conventional half-membrane coverage+Shikerun water retaining agent treatment increased the yield by 19.68%and 9.28%,respectively,compared with the treatment control and conventional half-membrane coverage(P<0.01);The conventional halfmembrane coverage+Shandong Runhan Water Quantum and the conventional half-membrane coverage+Hairuida water retention agent treatment are not significantly more effective than the conventional halfmembrane treatment(P<0.01).
