| 摘 要： | 通过2个生长季的田间试验,研究了黄淮海平原播前土壤水分对冬小麦生长发育、籽粒产量及水分利用的影响。结果表明,在播前不灌水条件下,越冬期或返青期灌水都可以获得较高的籽粒产量和水分利用效率,表明播前土壤贮存的水分可以满足冬小麦返青以前对水分的需求。在播前储水灌溉条件下,越冬期不需要灌溉,返青期是适宜的灌水时间;在拔节期或灌浆期灌水都会降低冬小麦的产量和水分利用效率。

| Abstract: | Effects of soil moisture before sowing on growth and development,grain yield and water utilization of winter wheat were investigated with field experiments during two growing seasons.Results shown that high yield and WUE(water use efficiency) could be acquired with watering during overwintering or reviving period under the condition of no irrigation before sowing,indicating soil moisture stored in soil before sowing could meet the demand of winter to water before reviving.Under the condition of storage irrigation before sowing,winter wheat didn’t need irrigation during overwintering period;the appropriate irrigation time was the reviving period.Yield and WUE decreased with watering during jointing or seed filling period.The results would help deal with the consecutive winter-spring drought during nearly two years. |
