从１９８０～１９９８年已有连续１９个暖冬。暖冬对长江中下游冬麦区小麦生育的影响，总体上看对小麦越冬期的光温配置较为适宜，叶蘖同伴协调，根系发育良好，叶蘖生长偏旺。但暖冬使越冬期和返青期温差不明显，小麦生育进程与季节不同步，适期早播种小麦拔节期可提前达１个 From 1980 to 1998, there have been 19 warm winter months. The effect of warm winter on the wheat growth in the winter wheat region of the middle and lower reaches of the Yangtze River, on the whole, the light and temperature allocation of winter wheat is more appropriate, the coordination of the leaf tiller companion, the root system developed well, and the growth of the tiller tilts. However, the warm winter so that the temperature difference between wintering and returning to green is not obvious, the process of wheat growth and the season is not synchronized, early sowing of wheat can join the early stage of up to 1
