| 摘 要： | 为了解保水剂施入土壤后对土壤性质的影响，促进保水剂在抗旱节水中的合理应用。在河北农业大学实验基地，对青海“绿宝”公司提供的3种剂型保水剂施入土壤后的混剂土进行土壤水分常数、密度、pH值、土壤膨胀率和土壤硬度等性能测定。结果表明：保水剂能显著提高土壤中的土壤水分常数和土壤孔隙度，但混剂土的土壤密度减小；保水剂能明显提高土壤的膨胀性能65％-170％；保水剂加入土壤后对土壤的pH值影响较小；在土壤大量失水后，保水剂能明显降低土壤坚实度，对照土壤的硬度是混剂土硬度的5．2—32．9倍。 |

| Abstract: | In order to find out the effects of super absorbent polymers(SAP) on physical and chemic characteristics of soil and apply it reasonably on drought resistance and water saving,soil moisture constants,soil density,pH values,soil expansion ratios and soil hardness of SAP-mixed soil were measured at experimental station,Agricultural University of Hebei.The three kinds of SAP were offered by Lvbao Company,Xining,Qinghai Province.Results indicate that SAP can make soil moisture constants and soil porosity increa... |
