| 摘 要： | 选用15个春小麦品种(系),设3个灌溉处理,通过田间试验研究了不同灌溉模式下春小麦在产量和水分利用效率方面的差异。结果表明:在适度灌水条件下春小麦产量和水分利用效率最高。生育期2次灌水处理(T2)产量和水分利用效率分别比1次灌水处理(T1)和3次灌水处理(T3)高4.47%,15.76%和10.24%,25.31%。随着灌水量的减少,春小麦生育期缩短,各品种平均生育期T1比T2和T3分别缩短1.33~6.33 d和5~11.33 d,但对不同品种的影响有所不同,张96-49和选920-1生育期对水分差异的反应较其它品种敏感,在3个水分处理间的差异比较大。 |

| Abstract: | Field experiment was conducted to investigate yield and water use efficiency(WUE) of spring wheat under different irrigation schedule. 15 spring wheat varieties and 3 different irrigation models were selected in this study.The results indicated that the yield and WUE of spring wheat under twice irrigated treatment(T2) were the highest although there were differences between different varieties.The former increased by 4.47% and 10.24% and the later did by 15.76% and 25.31% respectively,compared with that under once irrigated(T1) and three times irrigated ones(T3).With the decrease of irrigation quota,process of spring wheat shortened and that under T2 was shorter by 1.33 to 6.33 days and 5～11.33 days respectively,compared with that under T1 and T3. The processes of Zhang96-49 and Xuan920-1 had sensitive reaction on water schedule that had significant different between different treatments. |
