摘要： 为了研究播期对稻茬强筋型小麦品质性状的影响，以强筋型小麦品种‘豫麦34’为试验材料，在沿黄稻区设置3个播期处理：10月8日、10月18日、10月28日，采用完全随机区组设计，收获后测定籽粒的蛋白质及组分含量、淀粉含量及组分含量、粉质参数值。结果表明：沿黄稻区的稻茬强筋小麦在10月8日至28日期间，随着播期推迟，籽粒蛋白质含量显著提高，最高为14.32%、最低为11.27%；淀粉含量下降，最高为77.63%、最低为62.67%；对蛋白质各组分和淀粉各组分含量的影响结果不尽一致；综合面粉质量参数评价结果，中期（10月18日）播种的较优：形成时间6.70 min、粉质质量指数99.26 mm、吸水率71.06%、稳定时间7.02 min；晚期播种（10月28日）表现较差：形成时间5.34 min、粉质质量指数91.46 mm、吸水率64.94%，稳定时间7.58 min。

Abstract: In order to study the influence of sowing date on the quality trait of strong gluten wheat, taking‘Yumai 34’strong gluten wheat as the experimental material, three completely randomized block designs were conducted in the stubble-field of Yellow River area for sowing dates: Oct. 8th, Oct. 18th, and Oct. 28th, then after harvest, parameters such as protein content and its components, starch content and its components, and farinograph values were measured. Results showed that during Oct 8th to 28th, when sowing date was postponed, grain protein content increased significantly: the highest was 14% and the lowest was 11.27% ; starch content decreased: the highest was 77.63% and the lowest was 62.67%. The effect of sowing date on protein components and starch components differs inconsistently. Taking into consideration of flour quality and the results of parameter assessments, the experiment indicates that mid-time (Oct 18th) sowing was the best: the formation time was 6.70 min, the farinograph quality index was 99.26 mm, the water absorbing rate was 71.06% and the stability time was 7.02 min. Late-time (Oct. 28th) sowing performs worst: the formation time was 5.34 min, the farinograph quality index was 91.46 mm, the water absorbing rate was 64.94% and the stability time was 7.58 min.
