微咸水灌溉对河北低平原区土壤盐分及棉花的影响
Effect of Saline Water Irrigation on Soil Salt and Cotton in Hebei Low Plain
摘要
Abstract
Field experiments were conducted to investigate the effects of border irrigation with 2 g/L saline-fresh blending water on soil salt dynamic and cotton yield and quality in 2 experimental stations in Hebei low plain.The results showed that there were not significant differences between the irrigation of fresh water and 2 g/L saline water on cotton yield and quality.The salt content in soil profiles under saline water irrigation was higher compared with fresh water irrigation,but it didn't exceed cotton threshold of salt resistance and could be maintained banlance among different precipitation years in 2 experimental stations.So in Hebei low plain,the irrigation of 2 g/L saline-fresh blending water on cotton is safe and feasible.关键词
