中文摘要：

通过肥液（KNO3溶液）室内入渗试验,模拟研究了地下水位埋深150 cm条件下灌水定额对波涌灌溉土壤间歇入渗特性的影响。结果表明,在试验条件下平均入渗速度随灌水定额的增加而减小;灌水定额越大平均周期减渗率越大;土壤含水率增幅随灌水定额的增加而增大;灌水定额越大,土壤水分向下运移越深,进入地下水中的水量越多,越容易造成地下水污染和水资源浪费。

英文摘要：

Based on experiments of fertile solution infiltration, the main effects of irrigation quota on infiltration rate were studied with a 150cm groundwater table. The results indicate that the average infiltration rate reduces with the increase of the irrigation quota. The average infiltration reduction rate increases with the increase of the irrigation quota. The changing of the soil water content increases with the increase of the irrigation quota. The wetting front transport distance and the water enternee in the groundwater increase with the irrigation water quota increasing.
