2021年度，山东发生极端涝害，小麦播期整体延迟。本研究以超强筋小麦济麦44为材料，设置5个播期，分析极端涝害条件下不同播期对济麦44产量和品质性状的影响。结果表明:冬前分蘖随播期推迟而明显减少;产量随播期推迟而降低，W1处理(10月25日播种)的最高，为8 359。05 kg/hm2;穗粒数随播期推迟整体呈减少趋势;单位面积穗数和千粒重整体均呈先增加后减少趋势，W1、W2处理(11月5日播种)显著高于其他处理。W3处理(11月15日播种)小麦籽粒各项品质指标整体较好;产量最高时(W1)，籽粒中各矿质元素含量均最低;籽粒品质较好时(W3)，各矿质元素含量相对也较高，尤其是K、Na、Zn、Se、Cu的含量均最高。综上得出，如遇极端天气，鲁中地区超强筋小麦济麦44的播期控制在11月15日之前时，晚播对其产量和品质的影响较小，可实现一定程度上的优质高产，并且对矿质元素含量的影响较小。
Effects of Late Sowing on Yield and Quality of Super Strong Gluten Wheat Jimai 44 under Extreme Waterlogging Conditions
Under the conditions of extreme waterlogging in 2021,the sowing date of wheat was postponed as a whole.In this study,the super strong gluten wheat Jimai 44 was used as material,and five late sowing dates were set to study the impact of different late sowing date on yield and quality of Jimai 44.The results showed that the tillering before winter obviously decreased with the delay of sowing date,resulting in the de-crease of yield.Under the W1 treatment(sowing on 25th October),the maximum yield was obtained as 8 359.05 kg/hm2.The number of grains per spike decreased with the delay of sowing date.The number of ears per 666.7m2 and thousand-grain weight showed the trend of firstly increasing and then decreasing,and those of W1 and W2(sowing on 5th November)treatments were significantly higher compared to the other treatments.The overall quality parameters of the grains were better under W3 treatment(sowing on 15th November).When the yield was the highest(W1),the content of various mineral elements in grains were the lowest.When the grain quality was better(W3),the content of various mineral elements were relatively higher,espe-cially that of K,Na,Zn,Se and Cu,which were the highest.Therefore,in case of extreme weather,the lat-est sowing date for the super strong gluten wheat Jimai 44 in the central region of Shandong Province was rec-ommended to before 15th November to make sure the lowest impact on its yield and quality,which could a-chieve a certain degree of good quality and high yield,and has relatively small impact on the content of miner-al elements.
