摘要
研究旨在寻找制约本地小麦高产、稳产、优质的主要气候和气象因素,为提高小麦产量和品质提供气象依据。选取驻马店市小麦生长季气候、气象及小麦生育相关资料,并与豫北小麦高产区新乡进行模拟对比分析。经研究,驻马店市热量资源丰富,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本地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。驻马店小麦气候存在三短一长的特点,小麦生态表现为:群体大成穗多,单株小穗数少、不育小穗多,籽粒饱满度差。
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 precipitation time-space distribution brought about drought and wet injury,reverse,thunderstorm winds frequently.Later reverse and wet injury were the major limiting.Factors in high-yield of the local wheat compared with Xinxiang.Although the light was enough in general,but inadequate illumination had great influence on the wheat during rainy and low temperature.Winter wheat climate had characteristics of three short and a long,large groups,more grain,less panicles per plant,more infertility spikelet,low grain plumpness are the growth characteristics of the local winter wheat.
