Study on threshold value of Irrigation with SalineWater and Response function of Cotton Yield to Salt with drip irrigation under mulch

, 2010
本研究以中国科学院阿克苏绿洲农田生态系统国家野外研究站为依托，采用盆栽、测坑试验，研究咸水灌溉条件下膜下滴灌棉田土壤水盐动态规律、灌溉水矿化度对土壤理化性质与棉花生物量及水分利用效率的影响，探求膜下滴灌棉花灌溉水矿化度指标；建立棉花盐分生产函数，推求膜下滴灌棉花耐盐度指标，为棉田水盐综合调控和灌溉管理提供基本技术参数。主要结论如下：（1）咸水灌溉条件下生育末土壤储水量随着矿化度的增加而增大；随着灌溉水矿化度的增加，且盐分在表层积盐越明显。（2）咸水灌溉对土壤容重、田间持水量、饱和导水率影响不大 ...

高矿化度水灌溉条件下土壤盐结皮层与下层土壤盐分特征差异初探/The variability of salt characteristics from salt crust to subsoil in the shelterbelts along Tarim desert highway[J]

, 2014
塔里木沙漠公路防护林生态工程沿线均采用高矿化度咸水灌溉,土壤盐分是该线新人工生态系统可持续面临的主要环境问题之一.为了探讨长期灌溉条件下土壤表层盐分与土体内部盐分差异性,在沙漠公路定点采样的基础上,运用统计分析、相关分析等对土壤盐结皮层与盐结皮层下(0-100cm)土层电导率、全盐量的关系、盐离子含量、各土层盐离子间相关性关系做了比较分析.结果表明:盐结皮层土壤盐分显著高于下层土壤,沿线不同层次土壤pH均呈碱性,处于弱变异程度,相比较盐结皮层更趋向于碱性.长期高矿化度水灌溉下 ...
