摘  要：
为探明滴灌和施肥对南疆枣园土壤盐分含量的影响,研究了不同水肥处理的土壤电导率分布规律。结果表明,适宜灌溉定额和施肥配比能够达到抑盐脱盐的效果。施肥的单因子效应高于灌溉定额的单因子效应。而氮肥的施用比例对土壤电导率的影响作用显著,当施肥配比中氮钾肥的施用比例达到7∶3时,土壤显著积盐。W4F4处理脱盐率较高,节水控盐效果较好。

摘  要：
This study aims to investigate the influence of drip irrigation and fertilizer on soil salinity of jujube fields in the south Xinjiang. The effects of water-fertilizer coupling on the distribution of soil conductivity are studied under surface drip irrigation. The results show that suitable irrigation quota and fertilization ratio can achieve the effect of soil desalination; the single factor effect of fertilization was higher than that of irrigation quota; the effect of nitrogen fertilizer on soil conductivity is significant; when the ratio of nitrogen fertilizer to potassium fertilizer reached 7 ∶ 3,the soil was obviously salification; the desalinization rate of treatment W4 F4 is higher,thereby the water saving and salinity control effects are better.
