To research the characteristic of soil water and salt transport under subsurface drip irrigation(SDI) in Xinjiang based on the experiment on saline soil and observation on large field under SDI.
为探讨新疆盐碱土地下滴灌条件下土壤水盐运移的特点 ,进行了一定供水条件下地下滴灌入渗实验 ,并观测了大田地下滴灌条件下土壤水分和盐分数据 ,结果表明地下滴灌条件下土壤水盐运移的特点是 :滴头附近含水量最高 ,并向周围湿润锋处逐渐降低 ,对于均质中壤土 ,则均匀降低 ,湿润体近似圆柱 ,垂直方向土壤含水量和含盐量的分布图类似抛物线 ,而含盐量的分布则是在滴头附近最低 ,向周围湿润锋处逐渐升高 ,即含水量和含盐量的分布范围基本相同 ,含量高低相
