摘要

蓄水坑灌法是一种适用于我国北方山丘区果林灌溉的新方法。蓄水坑灌条件下的土壤水分入渗是在变水头条件下进行的。本文着眼于研究蓄水坑的侧向水平入渗

通过室内试验

对水平土柱在不同水头作用下的土壤入渗状况进行研究

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。这一研究成果对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具有重要价值。

Abstract

Water storage pitirrigation method is a new method suitable for orchard irrigation in gully area in the North China. Water infiltration is under varying-head condition. Considering the study lateral horizontal inf iltration of water storage pit

the experiments of infiltration in different heads were studied by horizontal column. 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 inf iltration indexes both vary alternately between relative-stable and obvious variation as infiltration head increasing.The research result swill have an important value for studying further vary ing-head infiltration and soil moisture characteristic of water storage pitirrigation.
