摘要
盐分的淋洗是阿拉尔灌区农业生产的重要环节。通过室内垂直入渗试验研究了淋洗水量和土壤初始含水量对阿拉尔灌区土壤脱盐状况的影响。结果表明,土壤含盐量分布和土壤盐分浓度随土层深度的增加呈指数函数增加,随土壤初始含水量的增加而减少,并且Cl-浓度也随土层深度的增加而增加。这为阿拉尔灌区设计合理的淋洗水量提供参考。
Leaching salt is an important part of the agricutural production in irrigation areas in Alar. Through indoor vertical infiltration experiments, research is done on how the leaching water volume and initial soil water content influence the desalting conditions of irrigation soil in Alar and the leaching. The results indicate that salt content distribution and salt concentration distribution increase exponentially with soil layer depth, decreased with initial water content,and the chloride ion concentration increase with soil layer depth. An analysis of the factors influencing water-desalting efficiency serves as a reference to the design of reasonable leaching water volume.
