摘要： 为了给小麦高产优质育种和栽培提供理论依据，以‘临优7287’为材料，采用连续挂牌标记法，研究播期对小麦主茎及分蘖农艺性状、产量和品质的影响。结果表明：同一品种，播期越晚，分蘖数越少。10月13日和10月18日播种的小麦无分蘖的株数达50%以上；播期对小麦主茎及分蘖的产量性状影响均表现为主茎穗粒数和千粒重高于分蘖。10月13日播种的小麦主茎穗粒数最多达37.2粒，10月3日播种分蘖为1的小麦主茎千粒重最高为45.56 g；不同播期小麦均表现为分蘖麦谷蛋白含量和总蛋白含量高于主茎，10月3日播种分蘖为2的小麦Ⅱ蘖麦谷蛋白含量最高达4.40%，10月8日播种分蘖为2的小麦Ⅱ蘖总蛋白含量最高为12.33%；分蘖加工品质优于主茎。10月3日播种分蘖为2的小麦Ⅱ蘖和10月13日、10月18日播种的小麦Ⅰ蘖评价值最高均为50；不同播期小麦均表现为分蘖淀粉糊化特性优于主茎。因此小麦生产上，应选用多穗型品种，通过必要栽培管理措施，保证低位蘖成穗，不仅高产而且优质。

Abstract: In order to provide a theoretical for high yield and quality of wheat, the study of effect of sowing dates on agronomic character, yield and quality of the main stalks and tillers in ‘Linyou7287’. The results showed that, sowing the delayer, the less tillers of wheat. The wheat had no tilling up to 50% sowing on October 13 and 18. Grains per ear and 1000-grain weight of the main stalks were more than tillers in different sowing dates. When the wheat had one tiller, grains per ear of main stem was 37.2 sowing on October 13, 1000-grain weight of main stem was 45.46 g sowing on October 3. Glutein content and total protein content of tillers were more than the main stalks. When the wheat had two tillers, glutein content of Ⅱ was 4.40% sowing on October 3. Total protein content of Ⅱ was 12.33% sowing on October 8. Processing quality of tillers was superior to the main stalks in different sowing dates. The Evaluation value was 50 in Ⅱ of two tillers sowing on October 3 and Ⅰ of sowing on October 13 and 18. Starch pasting properties of the main stem relatively poor, we should choose a multi-tillering-panicle varieties, cultivation and management, or adopt the necessary measures to ensure that low-tiller into the ear, not only high-yield and high quality.
