高产冬小麦生育后期0～40厘米土层的适宜土壤含水量指标:开花至完熟期田间最大持水量为60～65%;开花至乳熟期为65～70%;面团至完熟期为50～55%.开花期浇水对提高小麦产量影响最大,其次为灌浆期浇水,麦黄水对提高粒重及产量无明显正作用,在浇足开花水和灌浆水的情况下浇麦黄水对产量不利.一般干旱年份,浇足开花水和灌浆水即可获得最佳产量.小麦开花25天以后应停止浇水.
Suitable soil moisture content of 0-40 cm soil layer of high-yielding winter wheat at later growth stage: 60-65% of the maximum water holding capacity from flowering to maturity; 65-70% of flowering to milky ripening; 50-55% % .Water flowering at the flowering stage has the greatest effect on increasing wheat yield, followed by watering at the filling stage, wheat bran water without any significant positive effect on grain weight gain and grain yield, The yield is unfavorable.Under dry years, the best yield can be obtained by pouring enough flowering water and grouting water.Will stop watering after 25 days of flowering.
