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.

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. Pentad average temperature greater than or equal to 5 degrees C, or effective accumulated temperature (≥5 degrees C) higher than 20 degrees C could be regarded as the temperature index for the period of sap flow, and effective accumulated temperature (≥5 degrees C) of 100 degrees C was the temperature index for leaf flushing period. The temperature requirements for S. chinensis during mature period were the average temperature above 20 degrees C and effective accumulated temperature (≥10 degrees C) above 1500 degrees C. The water critical period of S. chinensis was also the young fruit enlargement period, and precipitation between 70 and 80 mm might meet the needs of plant growth. The correlation between growth rate of S. chinensis and daily average temperature could be described by a conic curve. The optimum temperature for the growth of S. chinensis was daily average temperature of 24 degrees C.
