To study the effects of quality of water on soil and plant, an experiment was conducted at Rudashat Drainage and Reclamation Experiment Station in 1999. Four irrigation water salinities (2, 5, 8 and 11 ds m(-1)) and two sugar crops (sugar beet and sweet sorghum) were used in this experiment. The results showed that under the same water quality, sweet sorghum used 2700 cubic meter per hectare less water than sugar beet. As the quality of irrigation water decreased, the soil salinity and exchangeable sodium percent increased which caused yield reduction for both plants. Sugar beet by accumulating Na and Cl in its leaves tolerated salinity but its usage as a forage crop caused some limitations, whereas sweet sorghum by not accumulating Na and Cl escape salinity and it can be used as a forage crop without any limitation.
为研究水质对土壤和植物的影响，1999年在鲁达沙特排水与垦殖实验站进行了一项实验。该实验采用了四种灌溉水盐度（2、5、8和11 ds m(-1)）以及两种糖料作物（甜菜和甜高粱）。结果表明，在相同水质条件下，甜高粱每公顷用水量比甜菜少2700立方米。随着灌溉水质量下降，土壤盐分和交换性钠百分比增加，导致两种植物产量降低。甜菜通过在叶片中积累钠和氯来耐受盐分，但其作为饲料作物的用途存在一些限制，而甜高粱不积累钠和氯从而避免了盐分影响，并且它可以毫无限制地用作饲料作物。
