中文摘要	为了给弱筋小麦田间水分管理提供合理依据，以弱筋小麦品种豫麦50为材料．在池栽防雨务件下研究了两种土壤贮水条件下灌水对小麦籽粒品质性状及产量的影响。结果表明。在底墒充足条件下，豫麦50籽粒主要品质性状优于底墒不足的品质性状。灌水对底墒不足条件下品质性状的影响大于对底墒充足务件下的影响，且各个品质性状受影响的程度不同。在底墒充足条件下以全生育期灌4水的弱筋小麦品质最优，抽穗期灌1水次之；而在底墒不足时全生育期灌4水和全生育期不灌水多数品质性状较优。底墒充足条件下的小麦籽粒产量、耗水量均高于底墒不足的产量和耗水量，而水分利用效率则较低；两种土壤贮水条件下的耗水量均随灌水次数增加而增加，而水分利用效率则降低；产量随灌水次数增加而增加，但灌水过量反而降低。据此提出了麦播前贮好底墒的重要性，以及不同底墒每件下小麦高产优质高效栽培的水分运筹建议。
英文摘要	In order to investigate the effects of different irrigations on grain quality traits and yield of winter wheat cultivar （Yumai 50, a weak gluten）, experiments with shielding from rainfall during all growing stages were conducted for 2002-2003 growing season with poor soil water storage （470.23 mm） in the 2m soil layer before sowing and 2003-2004 witti rich water storage （673.76 mm）at the Luoyang Arid Land Experiment Station of China Academy of Agricultural Sciences. The results indi cated that the wet gluten content, water absorption, stability time, area, extensibility and ratio etc. at the rich soil water storage before sowing were better than that at the poor soil water storage. The effects of irrigation on grain quality traits at the poor soil water storage before sowing were stronger than that at the rich soil water storage. The effects of irrigation on every quality traits were different. The regulating effects of irrigation on quality ,traits were analyzed in two growing seasons with different soil water storage in accord with the quality traits of weak gluten wheat. It was showed that quality traits with 4 time irrigations were better than that with one irrigation at heading under the rich soil water storage before sowing. That quality traits with 4 time irrigations and no irrigation were fine under the poor soil water storage before sowing. The grain yield and water consumption at the rich soil water storage before sowing were higher than that at poor soil water storage, but the WUE（water use efficiency） at the rich Soil water storage before sowing was lower. The water consumption increased and WUE declined with increasing irrigation, the grain yield increased with increasing irrigation but descended with overabundance. The paper showed that it was important to prepare proper soil water content before sowing. Some suggestions were also put forward for harmonizing high yield, quality and high efficiency in wheat cultivation under different soil water storage before sowing.
