摘　　要：为给地下水浅埋区再生水作物安全灌溉提供科学指导,该文利用地中渗透仪控制地下水位,研究不同地下水埋深条件下再生水灌溉对冬小麦生长的影响。结果表明:灌水量相同时,地下水埋深对作物生长影响顺序为:埋深2 m>埋深3 m>埋深4 m;灌水量不同时,地下水埋深为2 m的处理,低水处理较高水处理更能促进冬小麦干物质量和产量的增长;地下水埋深为3 m和4 m时,高水处理较低水处理更能促进冬小麦干物质量和产量的增长。再生水灌溉对冬小麦生长有一定的促进作用。To guide reclaimed water irrigation for winter wheat in the shallow buried groundwater region, the impacts of reclaimed water irrigation on winter wheat growth under different groundwater tables, which were controlled in the lysimeter, were analyzed. Results indicate that, with the same irrigation amount, the influence of groundwater table at 2 m on crop growth are most significant, followed by 3 m and 4 m. While with the different irrigation amounts, for groundwater table at 2 m, the increase of dry matter and yield would be accelerated evidently by low irrigation water comparing with high irrigation water; for groundwater table at 3 m and 4 m, the increase of dry matter and yield would be accelerated evidently by high irrigation water comparing with low irrigation water. Reclaimed water irrigation could accelerate winter wheat growth.
