摘要

为研究农田控制排水措施对土壤水分状况的影响,2010年在湖北四湖工程管理局排灌试验站进行大田控制排水和自由排水对照试验,在棉花生育期内观测土壤含水率,分析了控制排水对土壤含水率的影响,并对几次典型降雨前后土壤含水率进行了对比分析。结果表明控制排水措施能保持土壤水分,减少土壤含水率的波动,尤其在降雨后保持田间水分的效果更为明显,但土壤含水率与控制水位间相关关系不明确。

Abstract

In order to study the effect of controlled drainage on soil moisture, we carried out experiments of controlled drainage and free drainage for comparison in the land for growing field crops at Drainage and Irrigation Station in Jingzhou, Hubei province, 2010. We observed the soil water content in the whole cotton growth period and analysed the coefficient of soil water content variation. Results showed that controlled drainage had an obvious effect on soil water content in the whole growth period by retaining moisture and reducing the fluctuation of soil water content especially after rainfall, but the relation between soil water content and controlled water table was not definite.
