驻马店市冬小麦主要气候特征及高产气象因素

经系统分析研究驻马店小麦生长季气候、气象及小麦生育相关资料，并与豫北小麦高产区新乡进行对比分析：驻马店热量资源丰富，能基本满足冬小麦生长发育的需要，但与新乡相比波动性较大，缺乏稳定性。降水时空分布不均，干旱、渍害、连阴雨、雷雨大风灾害频发；与新乡相比，后期连阴雨和渍害是驻马店冬小麦高产的主要限制因子。光照条件虽基本能满足冬小麦生长发育需要，但后期阴雨天气时的低温、寡照对小麦高产影响较大。与新乡相比，驻马店小麦气候主要存在3短一长的特点，即：小麦适宜生长季短、穗分化时间短、灌浆期短、分蘖期时间长。小麦生态表现为：单株分蘖多、群体大成穗多，单株小穗数少、不育小穗多籽粒少，籽粒饱满度差、千粒重低。

The Main Climate Characteristics and High-yield Meteorological Factors of the Winter Wheat in Zhumadian

The main purpose of this study was to seeking mainly climate and meteorological factors of high and steady yield for improving the quality and providing meteorological basis of the local wheat.Simulation analysis was made based on the climate,meteorology and the winter wheat growth data between Zhumadian and Xinxiang.The results showed that heat resource was rich in Zhumadian and it can satisfy the need growth of the winter wheat,but compared with Xinxiang,it was lack of stability.Inequality of the precipit...
