利用地理信息系统软件，绘制灌区不同土壤层次的盐分分布图，定量评价了灌区内土壤盐渍化程度的分布状况。
The distribution maps of soil salt content were obtained using GIS, which quantitatively assess the distribution condition of saline soil in irrigation area.
通过田间定位试验，研究了水泥硬壳覆盖对盐渍化土壤蒸发、作物蒸腾、土壤盐分变化、作物生长发育状况、产量及水分利用效率的影响。
The effects of concret mulching on evaporation, transpiration, evapotranspiration, soil salt, yields of cotton and corn, water use efficiency were studied by field experiments.
因此灌水方式的改变在不增加灌水量的条件下改善了土壤水盐分布状况。
Changing irrigation method from continuous irrigation to surge flow irrigation can improve water salt distribution pattern under the condition of same precipitation rate.
