摘　　要：为探明气候变暖背景下湖北省各地小麦适宜播期,同时为鄂北地区小麦亩产千斤提供理论支撑,本研究对2008-2012年湖北省郧西等10个地区的气象数据进行了分析,依据在前期研究基础上提出的湖北省小麦主导品种郑麦9023的叶热间距,运用叶龄积温法推算得出郧西等10个地区的小麦适宜播期。生产上各地可根据此次研究结果,结合当地气象预报、土壤墒情以及小麦品种特性等适当调整小麦播期,确保小麦壮苗越冬、高产稳产。To determine the optimal wheat sowing da te in Hubei province under the background of global climate warming,the meteorological data of ten sites in Hubei province from 2008 to 2012 were analyzed.Based on the meteorological data of last five years with phyllochron intervals calculated in previous study,the optimal wheat sowing dates of ten sites in Hubei province were determined calculated by accumulated thermal time requirements for wheat leaves appearance method.In reality,the sowing dates could be adjusted by local meteorological forecast,soil conditions and the characteristics of wheat varieties based on the our results to ensure the safety of wheat production with high yield.
