荒漠草原植被抗旱保水剂应用技术研究

目的]研究抗旱保水剂对荒漠草原植被生长的改善效果。方法]在野外布置试验小区,采用条撒、面撒覆土和打孔3种不同形式施加保水剂,监测小区内土壤含水量、植被长势,分析不同保水剂施加形式的区别。结果]荒漠草原生长期内,施加保水剂明显提高了0~20 cm层土壤的含水量;3种保水剂施加方式中,打孔及面撒覆土方式的保水效果较为显著。结论]施加保水剂可以有效改善荒漠草原的植被生长情况。

Study on the Application of Water Retaining Agent on Desert Steppe

Objective ] The research aimed to study the improvement of water retai~ning agent~on the desert steppe growth. Method ] The test plots were set in the wild, and water retaining agent was added with strip spreading, surface spreading and drilling. And the soil water con- tent, vegetation growth was monitored between plots, so as to analyze the difference of three addition ways of water retaining agent. Result] The results showed that during growth period, 0 - 20 cm layer of soil moisture increased significantly after the addition of water retaining agent. And among the three addition ways of water retaining agent, drilling and surface spreading owned better effects. Conclusion] The addition of water retaining agent could improve the growth situation of desert steppe.
