摘 要:渭北旱原西部冬小麦多因子栽培试验表明,增施肥料是高产优质的主要措施,目前把有限的肥料首先投放在大面积中、低产田是高效的。播期也有重要的作用,适期为9月24日~10月1日,早晚幅度与冬前积温有关。选用良种依然是高产优质的基础和首要条件。Through the cultivation experiments of winter wheat with multifactors inthe west part of Weibei Rainfed Highland,the results showed that an increaseof application of fertilizers was the main measure for high production and be-tter quality of winter wheat.At present,it is better to put the limited fertili-zer resources into the fields with low productivity over a large area.The so-wing time is also so important that September 24 to October 1 are the righttime for sowing winter wheat,and the changeable margin is associated withthe cumulative temperature in winter.Also,selection and utilization of betterwheat cultivars are the base and first importance for high production and goodquality of winter wheat.
