摘要
试验研究不同基因型小麦各时期水分变动对产量的影响结果表明,拔节期水分变动对小麦产量的影响较大,干旱减产效应下普通小麦拔节期干旱处理比充分供水处理减产29.45%,而灌浆期水分亏缺处理仅减产12.70%;与水分胁迫处理相比,普通小麦拔节期复水处理增产42.83%,灌浆期复水增产22.29%,而不同基因型间小麦栽培一粒(A1)拔节期复水仅增产8.76%,栽培二粒(A2)拔节期复水产量下降4.38%。
The effects of water alteration on the yield of different wheat genotypes and stage were studied. The results show that water variation at the jointing stage has a great effect on the yield. Under the effect of dropping yield owing to drought, compared with that of the well-watered treatment, the common wheat yield shrinks 29.45 % at jointing stage, but only 12.70% at grainfilling stage. Compared with that of the water stress treatment, the common wheat yield increases 42.83 % after rewatering at jointing stage, while increases 22.29 % at grainfilling stage. Among different wheat genotypes, the yields of Zaipeiyili and Zaipeierli have only a change of 8.76% and 4.38% after rewatering at jointing stage.
