摘要
河西走廓各县市盐渍化土地较多。在张掖市东北郊开发区盐碱低洼地建植草坪的试验表明,通过 铺设双层暗管、施用磷石膏并灌溉技术等配套技术,能诱发与防除盐生杂草,改造盐荒地、重盐碱地,从而 种植出优质的草坪并大大降低土壤盐碱程度。
There are a lot of salinized lands across all counties in Hexi Corridor. This kind of lands could be improved and used properly. The experiments on planting turf in the saline-alkali lowland have been done in the northeastern suburban development zone of Zhangye City. The high quality turf lawn in the severe saline-alkali land could be established and mitigate the status of land salinization by the burying the hidden pipe of two layers and fertilizing phosphate gypsum in soil, which can induce growth of halophilous weeds and remove the weeds as well as employing the improved irrigation.
