以pH=7.9的水作为灌溉水源,土壤含水率、土壤密度及滴头流量不同的条件下,对土壤湿润体的变化过程进行试验,确定湿润峰及积盐范围,在积盐范围内混种盐角草和猪毛菜。测定土壤酸碱度及易溶盐离子总量的减少量,并积盐范围内混种的盐角草和猪毛菜与普通土壤中栽培的盐角草和猪毛菜的盐含量进行对比。结果表明,盐角草吸走部分Na+、Cl-离子,猪毛菜吸走土壤中的CO32-、SO42-离子,积盐范围内土深20cm处总含盐量降低了0.26g/kg。
Under the conditions of different pH value of water as irrigation water source, soil moisture content, soil density and dripper flow rate, the changing process of soil wetting body was tested to determine wetting peak and salt accumulation range, Saltwater grass and hairy vegetables. The soil pH and the reduction of soluble salt ions were determined. The salt content of the mixed saltfruits and Salsola populations in the salt accumulation area were compared with that of salt grass and salsola in general soil. The results showed that Salinagrass absorbed a portion of Na + and Cl- ions and Salsola surabilis drank CO32- and SO42- ions from the soil. The total salinity decreased by 0.26g / kg at the depth of 20cm in the salt accumulation area.
