施肥和灌溉方式对春小麦产量和水分利用效率的影响

Effect of Water-saving Irrigation on the Production and WUE of Spring Wheat

通过田间试验研究了不同的施肥方式和灌水方式对春小麦412产量和水分利用效率的影响。结果表明:中度灌水和中度施肥的处理水分利用效率最高,其产量与采用高度施肥和高度灌水的处理比较,其差异不显著(P>0.05);研究还发现随灌水量和施肥量的增加小麦的生育期延长。

Spring wheat 412 was selected to study the effect of irrigation and fertilization modes on yield and water use efficiency （WUE） of spring wheat with 3 irrigation treatments and 3 fertilization treatments. The results indicated that the treatment of medium irrigation and fertilization had the highest WUE, but the production had no significant difference from the treatment of high irrigation and high fertilization. The research also showed that the growing period of spring wheat 412 was prolonged with the increasing of irrigation and fertilization.
