摘要
本文根据田间入渗试验，分析了间歇积水入渗周期减渗率和平均周期减渗率等减渗特点，在此基础上，提出了沟道间歇积水入渗的减渗率模型，并进行了验证．
Field experiments are conducted to investigate the reduction of infiltration form the furrow under intermittent irrigation.Analysis of the cyclic filtration reduction ratios as well as their average value measured in the experiments reveals that the infiltration reduction characteristics of furrow intermittent infiltration can be simulated by a model proposed in this paper.
