通过田间畦灌试验,研究了冬小麦主要生育阶段的需水规律,分析了不同畦灌方式对冬小麦土壤水分及水分利用效率的影响,评价不同畦灌处理下的灌水质量及节水效益。结果表明,冬小麦灌浆期对水分需求量最大;与漫灌(CK )处理相比,冬小麦畦灌小区30 m ×3 m的灌水均匀度与灌溉效率最高,达到93.33%和84.46%,耗水量减少了5.96%,产量增加了25.30%,水分利用效率提高了33.24%,增收1561.61元· hm-2。结合当地实际生产情况,推广适宜的畦灌模式是入畦单宽流量5 L·m-1·s-1,畦宽3 m左右,畦长30 m左右为宜。
通過田間畦灌試驗,研究瞭鼕小麥主要生育階段的需水規律,分析瞭不同畦灌方式對鼕小麥土壤水分及水分利用效率的影響,評價不同畦灌處理下的灌水質量及節水效益。結果錶明,鼕小麥灌漿期對水分需求量最大;與漫灌(CK )處理相比,鼕小麥畦灌小區30 m ×3 m的灌水均勻度與灌溉效率最高,達到93.33%和84.46%,耗水量減少瞭5.96%,產量增加瞭25.30%,水分利用效率提高瞭33.24%,增收1561.61元· hm-2。結閤噹地實際生產情況,推廣適宜的畦灌模式是入畦單寬流量5 L·m-1·s-1,畦寬3 m左右,畦長30 m左右為宜。

Field experiment of border irrigation was conducted , have researched the water requirement of winter wheat during the major growing periods ,and analyzed the effect of different border irrigation methods to the soil water and water use efficiency of winter wheat ,evaluated the irrigation quality and the benefits under different treatment of border irrigation .The results indicated that :The maximal water requirement was at the filling stage of winter wheat .In contrast with the flood irrigation treatment (as CK ) ,the irrigation uniformity and irrigation efficiency of winter wheat by the bor-der irrigation with the plot of 30 m × 3 m was the highest ,reached 93 .33% and 84 .46% ,respectively .The water con-sumtion was decreased 5 .96% ,the yield was increased 25 .03% ,water use efficiency was increased 33 .24% ,and the added profit was 1561 .61 yuan·hm-2 .Therefore ,according to the local production situation of the winter wheat bound-ary irrigation area ,the appropriate border irrigation method was recommended that the inflow rate per unit width and bor-der width and length are 5 L·m-1·s-1 ,3 m and 30 m.
