摘要
利用田间试验方法，研究了不同水肥条件对冬小麦主要经济性状的影响．结果表明，限制黄土高原沟壑区冬小麦生产的最主要因素是肥而不是水．在任何灌水条件下，施肥对冬小麦的经济性状都有明显的正效应；而只有在施肥的条件下，灌水才有正效应；否则，灌水反而有负作用．
Field experiment shows that in Loess Plateau
galley regions, the most important limiting factor for wheat growth was fertilizer instead of water.
With irrigation, fertilization had a significant positive effect on the economic properties of winter
wheat, while irrigation could have a positive effect only when the fertilizer was applied.
