　　针对河北平原冬小麦生产中大面积采用秸秆还田和旋耕后直接播种给冬小麦出苗带来的不利影响，在河北藁城市进行了冬小麦抢墒播种（对照）、播前灌溉、抢墒播种后镇压3种处理对冬小麦生长发育及产量的影响试验。结果表明，播前灌溉和抢墒播种+播后镇压的产量分别比对照高6.9%和6.0%，与对照处理的产量达到显著差异(P<0.01)。因此，小麦抢墒播种加镇压可节省冬小麦底墒水，具有很好的节水增产效果，可以大面积推广。

Maize straw returning to the field plus rotary tillage before sowing winter wheat was the main model of winter wheat planting in Hebei Province. This planting model created unfavourable growing condition to the seedings of winter wheat. Field experiment was conducted to study the effects of different sowing practices on the yield of winter in Gaocheng City in Hebei Province. Three treatments were set up: no irrigation before sowing (CK), irrigation before sowing, no irrigation before sowing with rolling after sowing. The yield of the three treatments was in the order of irrigation before sowing > no irrigation before sowing with rolling after sowing > no irrigation before sowing. The yield under irrigation before sowing and no irrigation before sowing with rolling after sowing treatments were significant increased by 6.9% and 6.0% compared that of CK (P<0.01). No irrigation before sowing with rolling after sowing treatment could save the irrigation of pre-sowing and it could be extended as a water-saving practices in this region.
