摘要
主要研究了采取覆草、覆膜及保水剂等措施的保水效果。在对不同措施下土壤物理性状和入渗性能研究的同时 ,还进行了土壤水分动态变化研究。最后的试验结果表明 :覆膜的保水效果明显优于覆草 ,覆草又明显优于对照 ;适量的保水剂可有效提高土壤含水量 ;在新梯田、老梯田与坡耕地的保水效果研究中 ,保水效果强弱顺序为 :老梯田 >坡耕地 >
The effects of different water retention treatments such as covering with veil, covering with grass and using water retention preparation are studied. The conclusion obtained is as follows: the SWC was significantly increased by using water retention preparation; the sequence of water retention effect in three kinds of land was old terraced field>slope field>new terraced field; the sequence of water retention effect was covering with veil>covering with grass>check.
