摘　　要：本文运用相关分析法对2004—2018年北京市昌平区苹果不同生育期气象因子与产量的关系进行研究,结果表明,影响昌平区苹果产量的主要气象因子为3月底至4月(萌芽至开花期)平均最低气温,7月(果实生长后期)平均气温,8月(果实膨大期)平均气温、日照时数、湿度,9月(果实着色前期)气温日较差,10月(果实着色后期)平均气温、平均最低气温、日照时数、湿度。因此,昌平区苹果种植要重点预防萌芽至开花期低温冻害、果实生长期高温、果实膨大期高温以及果实着色期高湿多雨的不利影响。The paper studied the relationship between meteorological factors and the yield of apples in different growth periods in Changping District,Beijing City from2004 to 2018 by using the correlation analysis method.The results showed that main meteorological factors affecting apple yield in Changping District were the average minimum temperature during the end of March to April(from sprouting period to flowering period),the average temperature in July(fruit late growth period),the average temperature,sunshine hours and humidity in August(fruit swelling period),the temperature difference in September(fruit early coloring period),average temperature,average minimum temperature,sunshine hours and humidity in October(fruit late coloring period).Therefore,the cultivation of apple in Changping District should focus on preventing the adverse effects of lower temperature damage or frost from the sprouting period to flowering period,high temperature during the fruit growth period and fruit swelling period,and high humidity and rain during the fruit coloring period in the future.
