| 摘 要： | 采用物候与气象因子相结合的同步观测方法,对长春地区北五味子的生长特性和影响其生长率的气象因子进行研究.结果表明:北五味子返青前候平均气温在-5℃时可视为返青期即将开始的温度指标.日平均气温在-2℃时枝条开始返青.候平均气温≥5℃或≥5℃的有效积温高于20℃可作为进入树液流动期的温度指标.≥5℃的有效积温100℃是进入展叶期的温度指标.北五味子果实发育到成熟要求平均气温20℃以上,≥10℃有效积温1500℃以上.幼果膨大期是北五味子的水分临界期,此间降水量在70～80mm就可以满足植株生长的需要.日平均温度24℃为北五味子生长的最适温度. |

| Abstract: | A synchronous observation on phenological characteristics and meteorological factors was conducted in order to study the growth characteristics of Schisandra chinensis in Changchun region and the influencing factors on growth rate.Result showed that,the pentad average temperature of 5 degrees below zero Celsius could be regarded as the initial temperature for the returning green stage of S.chinensis,and the branches began to turn green when the daily average temperature reached 2 degrees below zero Celsius.... |
