为实施非充分灌溉条件下实时预报,通过在山西临汾地区冬小麦灌溉试验,研究了冬小麦在不同生育期、不同施肥条件下的耗水量及对冬小麦产量的影响。研究表明,冬小麦全生育期的耗水量在277~515mm之间,耗水量随灌水量的增加而增加,相应的产量也明显地提高。在相同灌水条件下,不同施肥量处理的耗水量差异不大,施肥量对冬小麦的耗水量影响不明显。
為實施非充分灌溉條件下實時預報,通過在山西臨汾地區鼕小麥灌溉試驗,研究瞭鼕小麥在不同生育期、不同施肥條件下的耗水量及對鼕小麥產量的影響。研究錶明,鼕小麥全生育期的耗水量在277~515mm之間,耗水量隨灌水量的增加而增加,相應的產量也明顯地提高。在相同灌水條件下,不同施肥量處理的耗水量差異不大,施肥量對鼕小麥的耗水量影響不明顯。

For implementation of the real-time forecast with non-sufficient irrigation conditions,,the article is through irrigation of winter wheat in Linfen of Shanxi Province,studied water consumption of the winter wheat at different growth stages and different fertilizer and influence on winter wheat yield.The result shown that the water consumption of the winter wheat growth period is between the 277 ~ 515mm,is increasing with the irrigation recharging,then its production increases correspondingly.Under the same irrigation conditions,the water consumption with different treatment of fertilizer is insignificant,the amount of fertilizer has no obvious influence on water consumption of the winter wheat.
