Effects of reclaimed water irrigation on winter wheat growth under different groundwater tables

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.
