| 摘 要： | 通过对膜下滴灌棉田施加旱地龙和禾康两种土壤改良剂,研究两种不同化学改良剂对改良盐碱地的应用效果及对棉花生长与产量的影响,为盐碱地改良提供理论依据.结果表明:在滴灌棉田施用旱地龙和禾康后,土体含盐量呈下降趋势,脱盐率分别为30.3%和17.7%,而对照区脱盐率仅为10.4%;借助钠吸附比概念对土壤阳离子组成进行分析,旱地...

| Abstract: | Soil salinization has been the main obstacle for agricultural development in arid area.It has been a focus how to improve saline or alkaline soil.In this paper,the experiments of different ameliorants named Handilong and Hekang under different irrigation ways were carried out to test their respective effects on soil improvement,cotton growth and cotton yield.The experiments show that,after applying the ameliorants,the soil sallinity in cotton field under drip irrigation was decreased,the desalinizalion rati... |
