摘  要:
[目的]研究再生水灌溉对冬小麦种植区土壤次生盐渍化的影响。[方法]基于新河灌区的再生水灌溉监测试验,采集再生水灌溉和井水灌溉的土壤样本,对再生水灌溉10年的土壤进行取样分析。[结果]再生水灌溉对土壤Na+的影响最为显著,增加了试验区土壤次生盐渍化的风险。在试验基础上,建立了再生水灌溉条件下土壤水-盐运移模型,采用Hydrus-1D模型模拟了冬小麦一个生长周期内(270 d)再生水灌溉条件下0~120 cm土壤内的水-盐运移状况。[结论]再生水灌溉期内,土壤中盐分累积效应显著。

摘  要:
[Objective]The research aimed to study the effect of reclaimed water irrigation on soil secondary salinization of winter wheat planting area.[Method]Based on the monitoring experiment of reclaimed water irrigation in Xinhe irrigation area,soil samples from reclaimed water irrigation and well water irrigation were collected,and the soil that was reclaimed for 10 years was sampled and analyzed.[Result]The effect of reclaimed water irrigation on soil Na+was the most significant,increasing the risk of secondary salinization in the test area.Based on the experiment,the soil water-salt migration model under reclaimed water irrigation conditions was established.The Hydrus-1D model was used to simulate the water-salt migration in 0-120 cm soil under the condition of reclaimed water irrigation in a growth cycle of winter wheat( 270 d).[Conclusion]Effects of salty accumulation were obvious during the irrigation period of reclaimed water.
