| 摘 要： | 为搞清生物活性保水剂对沙化土地治理效果，将植物秸秆制成具有强吸水功能的植物纤维素。同时，引用固氮菌、纤维素降解霉等多种微生物，制成活性保水剂，并将活性保水剂与常规树脂保水剂对模拟沙化土地治理效果进行了分析对比，得出的结果是：活性保水剂可以提高酶的活性，使土壤微生物的生育率提高17．0％，土壤密度降低了2．9％，具有治理沙化土地的效果。

| Abstract: | The effect of Bioactive Water Retaining Agent(BWRA) on the control of desertilized land was studied, and plant straw was decomposed into plant cellulose which has strong ability to absorb water and to develop BWRA with various microorganisms like nitrogen fixing bacteria and cellulosase. The control effect of BWRA and general resin water retaining agent on desertification land is analyzed. It shows that BWRA can raise the production of microorganisms by 17.0%, reduce the soil density by 2.9%. It can control the desertilized land thoroughly. |
