簸箕李灌区泥沙颗粒级配对土壤水入渗的影响

Effection of Sediment Particle Level on Soil Water Infiltration in Bojili Irrigation District

浑水灌溉有利于水资源的有效利用,提升土壤肥力,促进农业发展。该研究利用室内物理模型试验的方式,探讨不同土壤类型、初始含水率和浑水含沙量等试验方案下浑水泥沙颗粒级配对土壤水入渗特征的影响,并总结出相应的变化规律,可为灌区灌溉系数的确定和水资源合理配置提供依据。

Muddy water irrigation is beneficial to the effective use of water resources,improving soil fertility and promoting agricultural development.This study used indoor physical model test to explore the influence of soil water and sediment particle levels on soil water infiltration characteristics under different soil types,initial water content and muddy water sediment content test schemes,and summarized the corresponding change rules,which could provide a basis for the determination of irrigation coefficient and rational allocation of water resources in irrigation areas.
