摘  要:
通过室内试验,对水平土柱在不同水头作用下的土壤入渗参数进行研究,结果表明入渗水头对入渗系数有较为显著的影响,对入渗指数有一定的影响,入渗系数和入渗指数均随入渗水头的变化呈现出相对平稳与显著性变化的交替变化趋势。这一研究成果为进一步研究蓄水坑灌条件下的变水头入渗及土壤水分运动特性奠定基础。

摘  要:
Water storage pit irrigation method is a new method suitable for orchard irrigation in Northern China. Water infiltration is under varying-head condition. Through indoor experiment, infiltration parameters in different heads were studied by horizontal column in this paper. The results are shown that infiltration head has significant effect on infiltrate coefficient and has smaller effect on infiltration index, and the infiltration coefficients and infiltration indexes both vary alternately between relative-stable and obvious variation as infiltration head increasing. The research results will have an important value for to study further varying-head infiltration and soil moisture characteristic of water storage pit irrigation.
