中文摘要	[目的]土壤盐渍化是影响干旱区绿洲农业生产的主要障碍因素,在膜下滴灌条件下对比研究不同处理水灌溉对土壤水分渗漏及淋盐作用的影响,旨在提出一种高效降低土壤盐分的新技术.[方法]通过田间小区试验,设置常规滴灌对照(CK),一次磁化(T_1),二次磁化(T_2)3个处理,在不同土层埋设原位土壤溶液提取器和2m深土层接渗漏液,分析测定土壤水分渗漏量与含盐量.[结果]渗漏液的全盐含量、Cl~-和Na~+含量均呈现出CK
英文摘要	【Objective】Soil salinization is one of a major obstacle factors affecting crop yield in arid region. In this study, a field plot experiment was conducted to investigate the effects of magnetized water irrigation on soil water infiltration and soil salt leaching under the drip irrigation condition. The purpose of our research is to find a novel method to reduce soil salt content and prevent soil secondary salinity in water - saving agriculture.【Method】Using in situ soil moisture sampler and collecting soil leachate in 2 m soil layer, a field experiment was set up, and three treatments including Control (CK)., one times magnetized water irrigation (T_1)., two times magnetized water irrigation (T_2 )., soil water leachate, soil solution salt content and soil salt content were determined.【Result】Total salt content, and the content of Cl- and Na~+ of soil leachate variation trend was found as CK < T_1 < T_2. Soil solution salt content in 60 - 100 cm layer was greatly higher under magnetized water irrigation treatment than that of the CK, suggesting that magnetized water irrigation played a significant role in soil infiltration and soil salt leaching. Moreover, in contrast to one time magnetized water irrigation treatment, an more obvious soil salt leaching effect was found under the treatment of two times magnetized water irrigation. For instance, the amounts of soil water leachate were 80.27 kg, 91.39 kg and 87.99 kg, respectively, under CK, T_1, T_2 treatment, compared with control (CK)., the amounts of soil water leachate were increased by 13.9 % with T_1 and increased by 9.6 % with T_2 treatment. After the last water irrigation, soil Cl- concentration and soil Na~+ concentration in 0 - 100 cm soil layer decreased markedly, and the salt decreased degree order was CK
