| 摘 要： | 利用1985—2005年锦州大豆物候期及同期气象资料,应用数理统计方法,分析大豆物候期的气候响应。结果表明:大豆生长期的长短主要受积温和降水的影响,出苗期主要受积温和日照的影响。积温、降水和日照在大豆不同物候期内的作用不同,三叶期和成熟期是积温、日照和降水共同作用的结果,分枝期主要是受积温和日照的影响,开花和结荚期主要是受累计积温的影响。

| Abstract: | Based on soybean phenology data and the climate data from 1985 to 2005 in Jinzhou,the soybean phenology and its responses to climatic factors were analyzed by statistic methods.The results showed that the growing stage of soybean was mostly influenced by accumulated temperature and precipitation,the seedling emergence stage and branching stage by accumulated temperature and sunshine.Accumulated temperature and precipitation as well as sunshine played different roles in different phenological stages of soybean.Three-leaf stage and mature stage were affected by accumulated temperature and sunshine as well as precipitation,while full blooming stage and podding stage were mainly affected by accumulated temperature. |
