Effects of Irrigation Modes on Soil Hydraulic Properties
摘要
Abstract
Effects of different irrigation modes on soil saturated hydraulic conductivity were investigated by the method of measuring and fitting.The results show that,by drip irrigation under mulch,soil water conductivity was improved significantly,soil saturated hydraulic conductivity in the soil layer（0-100 cm） was much better than that by ground flood irrigation,and also better than that of bare and saline land.Under different irrigation modes,unsaturated hydraulic conductivity and unsaturated diffusivity of the soil layer（0-100 cm） were in the order of drip irrigation under mulch ground flood irrigation bare and saline land.Under drip irrigation under mulch,soil hydraulic properties may be influenced by the improvement of soil aggregate structure or the change of chemical composition of soil,rather than by soil texture,soil bulk density,and soil temperature,soil salt.关键词
