摘要
在参照农业气象灾害观测调查资料的基础上,利用苹果气候产量动态相对偏差百分率进行了农业气象灾害的统计分析和研究。结果表明,影响苹果正常生产的主要农业气象灾害是前一年9月干旱、次年苹果花期(4月下旬)高温干燥气候和低温交替危害造成的,冬季12月至翌年2月暖冬虽然不属于农业气象学上定义的农业气象灾害,但随全球气候变暖,暖冬危害明显加重,其危害程度仅次于前一年9月干旱。
Based on the data of agro-meteorological disaster investigation, the dynamic relative percentage of meteorological yield of apple has been analyzed. The results showed that the drought in September of the year before and high temperature and low temperature occurring alternately in April of the current year was the main meteorological disastrous factors for apple. It indicated that although there was no direct effect of the warm winter caused by the meteorological disaster, along with the global weather becoming warmer, the warm winter will be the harmful factor for apples.
