摘　　要：采取3因素多水平组合设计,利用2.5～6.0g/L不同矿化度微咸水对冬小麦进行灌溉。试验结果表明:冬小麦产量与微咸水矿化度呈负相关关系r=-0.7411,与微咸水灌溉量呈正相关关系。4.0g/L微咸水灌溉对土壤具有一定的脱盐作用;微咸水矿化度为6.0g/L时土壤中的盐分积累达到0.107个百分点。Irrigated2.5～6.0g /L brackish water under trials designed in combinatorial process with three factors at multilevel.The results showed that wheat yield was in negative correlation with the mineralize concentration of brackish water r=-0.7411and in positive correlation with the irrigation requirement of brackish water.Irrigation4.0g /L below brackish water had a certain wash salt con-tribution to the soil.Irrigation6.0g /L brackish water the salt concentration of soil had increased0.107percent .
