| 摘 要： | 在陇东旱塬通过人工创造不同的播前底墒，测定冬小麦产量、水分利用效率、关键生育期光合生理指标、主要品质等指标，研究了播前底墒对旱地冬小麦的效应。结果表明，随着播前底墒的增加，冬小麦的产量、水分利用效率、光合速率、光合量子产量显著增加，营养品质、磨粉品质和面粉加工品质明显改善。光合速率和籽粒品质在中底墒时最佳，高底墒略有降低，但仍优于低底墒。

| Abstract: | Based on analysis of the different manufactured soil water at planting stage(SW),the effect of SW on dryland winter wheat was studied,by testing and analyzing the yield,water use efficiency(WUE),photosynthetic physiological criteria in key growth stage and main quality index.The results showed that yield,WUE,photosynthetic rate(Pn),photosynthetic quantum yield significantly increased with the increasing of SW and nutrition quality, milling quality and processing quality of flour enhanced in evidence.The Pn ... |
