| 摘 要： | 应用2003．2008年静宁气象站、泾川气象站、崆峒区气象站物候资料，1995～2007年苹果产量资料及1951-2007年平凉市气象资料进行统计分析结果表明，不同地域苹果生育期间对降水量需求不同，近几十年来，静宁降水量变化总体呈上升趋势，能满足苹果花芽形成期及新梢加速生长期生长发育的需求，但泾川4月降水变化则呈下降趋势，不利于苹果花期及新梢生长期生长发育；各地年平均气温及生育期间≥10℃积温均升高；平凉市苹果产区全年日照为3000h，8—9月平均日照为330～360h，均可满足苹果生长对光照的要求。春季冻害加重，使苹果气候产量波动较大。

| Abstract: | Based on the phenology data from 2003-2008,output data of apple from 1995-2007,and meteorogical data from 1951-2007 in Jingning and Jingchuan and Kongtong,analysis was made by the statistics method.The result showed that apple's water requirement was different in different region during the growth period.In recent several decades,precipitation in Jing-ning showed an increasing trend,which was positive to the growth and development during apple's budding period and new branches growth,while Jing-chuan's prec... |
