在甘肃武威通过连续3 a田间试验，研究了不同灌水量对甘啤4号和甘啤7号产量和品质的影响。结果表明，3 a平均生育期灌水3 000 m3/hm2处理比灌水 6 000 m3/hm2处理早熟3 d左右，但在年份和灌水量相同的情况下，甘啤4号与甘啤7号生育期基本相同。3 a基本苗和成穗数甘啤7号均高于甘啤4号，不同灌水量对同一品种的基本苗和成穗数影响不显著，灌水量对两个品种蛋白质含量影响不显著。在不同灌水量下，3 a平均千粒重甘啤4号均高于甘啤7号，两个品种3 a的饱满度灌水3 000 m3/hm2处理均大于灌水6 000 m3/hm2处理。3 a平均折合产量灌水3 000 m3/hm2处理甘啤7号高于甘啤4号，灌水6 000 m3/hm2处理甘啤7号略低于或相当于甘啤4号。

Through a field experiment continuously for 3 years in Gansu Wuwei， the effects of amount of different irrigation on yield and quality of Ganpi 4 and Ganpi 7 is studied . The results shows that the average growing period continuously for 3 years in amount of irrigation 3 000 m3/hm2 is early maturing 3 days than that of 6 000 m3/hm2， but in the same year and irrigation conditions， growth period of Ganpi 4 and Ganpi 7 is basically the same . The basic seedling and panicle number for 3 years of Ganpi 7 is higher than that of Ganpi 4， different irrigation on the basic seedling and panicle number of the same variety is not significantly， the amount of irrigation is not significant for the protein content of two varieties . Under amount of different irrigation， the average 1 000-grain weight for 3 years of Ganpi 4 is higher than that of Ganpi 7， plumpness irrigation of two varieties for 3 years 3 000 m3/hm2 treatment are higher than 6 000 m3/hm2 treatment. The average yield for 3 years 3 000 m3/hm2 irrigation reatment Ganpi 7 is higher than that of Ganpi 4， 6 000 m3/hm2 treatment Ganpi 7 is slightly lower than or comparable to the Ganpi 4 .
