针对江汉平原小麦过度发展的状况 ,应用数理统计方法 ,分析了阴湿天气对小麦产量的影响。结果表明 :小麦减产的主要原因是阴湿天气危及到小麦产量构成 (有效穗数、穗粒数、千粒重 )。考虑到江汉平原历年多阴雨寡照 ,尚且不能对其进行人工控制 ,因此建议大量减少小麦在江汉平原的种植面积 ,变种植小麦为优质油菜 ,并与优质稻、棉实行连作或套作。
According to the situation of over-development of wheat in Jianghan Plain, mathematical and statistical methods were used to analyze the influence of wet and wet weather on wheat yield. The results showed that the main reason of wheat yield reduction was that the production of wheat was negatively affected by wet and dry weather (effective panicles, grains per spike and 1000-grain weight). Considering that there are many rainstorms in the Jianghan Plain in the past years and still can not control them manually, it is suggested that a large reduction should be made in the planted area of wheat in the Jianghan Plain. The wheat should be planted as high quality rapeseed and continuously or intercropped with high-quality rice and cotton.
