通过模拟高扬程灌区盐碱土类型，将土壤溶液配制成３～８ｇ／ｋｇ的定量盐分浓度，对大麦、小麦、玉米、蚕豆４种作物进行了盆栽试验，结果表明：以盐分浓度为依据，４种作物的耐盐能力依次为：大麦＞玉米＞蚕豆＞小麦；以Ｃｌ－含量为依据，其耐盐能力顺序为：大麦＞小麦＞玉米＞蚕豆。 Soil samples were prepared into 3 ~ 8g / kg salt concentration by simulation of saline-alkali soil types in high-elevation irrigation area. Pot experiments were conducted on 4 crops including barley, wheat, corn and broad bean. The results showed that: The ability of salt-tolerance of the crops is as follows: barley> corn> broad bean> wheat; the order of salt tolerance of Cl-content is: barley> wheat> corn> broad bean.
