摘　　要：通过对郑麦9023晚播不同播期的全生育期的追踪调查研究,综合评价晚播对郑麦9023的茎蘖动态、群体质量、产量构成、籽粒产量及品质的影响。结果表明,当强筋小麦郑麦9023因早播在11月份之前受到大的冻害而需重播时,或为了防止小麦旺长及冻害而进行晚播时,晚播时间最迟不要推迟到11月中旬。Comprehensive Evaluation effects that the late sowing Zhengmai 9023 stem tiller dynamics ,population quality , yield form , grain yield and quality, through the whole growth period studying for late sowing different sowing dates on Zhengmai 9023. The result that,when strong gluten wheat Zhengmai 9023 needs sowing again before November because of heavy freezing damage for early sowing, or wheat needs late sowing that it is prevented prosperous growing and freezing damage, the latest late-sowing didn＇t defer to the time in mid-November.
