咸水非充分灌溉对春小麦产量及水分利用效率的影响
Effect of Non-sufficient Irrigation with Saline Water on Spring Wheat Yield,Water Consumption and Water Use Efficiency
摘要
Abstract
Underground saline water has became an important source of irrigation water because of water shortage in northwest arid regions.This paper discussed the effect of non-sufficient irrigation with saline water on spring wheat yield、water consumption and water use efficiency through a field experiment in the middle reach of Shiyang River Basin.Results showed that either water stress or salt stress caused a decrease on spring wheat yield.But under slight salt stress,yield of spring wheat only reduced by 1%,while it reduced 6% under slight water stress.Water consumption of spring wheat also decreased under water stress or salt stress.The percentage soil water accounted for water consumption of spring wheat increased under non-sufficient irrigation,which was good for saving irrigation water.The treatment of highest water use efficiency was W2S2,which indicated that irrigation with moderate deficiency or saline water could reach the goal of saving water.关键词
