不同措施对提高沙地造林成活率的研究

Studies on promoting the survival rate of afforestation by different methods in sandy land

采用固体水、保水剂和覆膜措施 ,对提高造林成活率进行了比较试验。结果表明 ,与对照相比 ,这些措施明显提高了土壤含水量 ,从而不同程度提高了沙区造林成活率。其中覆膜措施效果最佳 ,其次为保水剂 。

Using three methods, namely, solid water, SAP and coverage of plastic film, the experiment which aimed to promote the survival rate of afforestation was arranged. The results showed that: comparing with controls, these methods could increase the water content of soil apparently, and consequently promoted the survival rate of afforestation at different degree in sandy land. Among these methods, the effect of solid water was good, SAP was better, and the effect of coverage of plastic film was the best.
