In order to provide the basis for selecting water-saving and high-yielding varieties, a field experiment were carried out to determine the effect of different irrigation patterns on growth characteristics and yield and protein content of winter wheat. Four varieties including tais-han 23, taiahan 223, Shannong 6 and Shijiazhuang 8 were used as test materials, three irrigation patterns were set, namely Wl ( only irrigation before sowing ) , W2 (irrigation before sowing and irrigation between jointing-booting stage) and W3 (irrigation before sowing, irrigation at jointing and anthesis). The production factors, leaf area index, accumulation of dry matter and grain protein content of the four varieties under different irrigation patterns were mainly studied. The result showed that there were significant difference in yield among Wl, W2 and W3 treatments and no significant difference among W2 and W3. Leaf area and dry matter accumulation increased with the increase of irrigation times and different varieties changed the performance differetly, Taishan 23 changed smaller than the other three varieties. All the four varieties showed that as the irrigation times increased while grain protein content reduced, and protein content of Wl were significantly higher than that of W2 and W3. According to the research, Taishan23 variety with yield potential had good adaptability.%为筛选推荐节水高产品种提供依据,研究了不同灌水模式对冬小麦群体动态和产量及蛋白质含量的影响.以泰山23、泰山223、山农6号和石家庄8号为试验材料,设置3种灌水方式,印W1底墒水(生育期不浇水)、W2底墒水+春1水(拔节水-孕穗期)和W3底墒水+拔节水+开花水.主要研究了不同灌水方式下4个品种的产量构成因素、叶面积指数、干物质积累及籽粒蛋白质含量性状.结果表明,W1和W2、W3之间产量差异显著,W2和W3之间产量差异不显著,品种之间产量差异显著.叶面积和干物质积累量随着灌水次数的增加而增加,但不同品种之间表现不同,泰山23较其它3个品种变化较小.不同灌溉模式对试验品种均表现为随着灌水次数的增加蛋白质含量减少,W1显著高于W2和W3.根据本研究结果可知,说明泰山23具有较好产量潜力和品种适应性.
