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>新梯田。

Abstract

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 o f water-retention ef fect 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.
