摘　　要：以离石王家沟流域官道梁坡地土壤为研究对象,对保水剂以及施加保水剂后土壤的吸水性及保水性进行了测定分析。结果表明:单位重量保水剂的吸水量在152~155 mL/g之间,最大吸水速率在19.63~21.90 mL/s之间。土壤中施加保水剂后,能有效抑制土壤水分的蒸发,提高土壤保水率。Taking guandaoliang slope soil in Lishi Wangjiagou Watershed as the research object,the water absorption and water retention of water retaining agent and soil after applying water retaining agent were measured and analyzed.The results show that the water absorption of water retaining agent per unit weight is 152~155 mL/g,and the maximum water absorption rate is 19.63~21.90 mL/s.The application of water retaining agent in soil can effectively inhibit the evaporation of soil water and improve the soil water retention rate.
