再生水灌溉冬小麦试验研究

对小店区西草寨和汾河灌区中心试验站冬小麦进行再生水和井水灌溉的对比试验研究,认为再生水灌溉比井水灌溉后,氮素在土壤中的含量要高,从而影响冬小麦的株高、叶面积和产量,指出再生水灌溉应适量减小施肥数量,避免农田氮素过量而导致的污染。

Experimental Study on the Irrigation of Winter Wheat with Regenerated Water

This paper makes the comparative and experimental study on the irrigation of winter wheat with regenerated water and well water in Xicaozhai Village of Xiaodian District and the central experimental station of Fenhe Irrigation Area,holds that the content of nitrogen in soil after the irrigation with regenerated water is higher than the content of nitrogen in soil after the irrigation with well water,which influences the stem length,leaf area and yield of winter wheat,and points out that in the irrigation with regenerated water the fertilizing quantity should be reduced adequately for avoiding the pollution caused by excessive nitrogen in farmland.
