【摘要】 温度条件是影响常绿植物能否引种成功的关键因素之一。本项研究通过统计分析太原地区2011年至2019年温度数据,设定平均温度、最高温度、最低温度三个因素分别以天、季度、年为周期对太原地区温度因素进行分析。分析结果表明,太原地区夏季高温普遍在36℃以下,不是常绿植物引种的关键因素,但是冬季最低温度普遍可达到-15℃以下,引种植株的半致死温度应不低于-15℃或采取必要措施防止引种植物冻害是决定引种是否成功的控制因素。结合温度与常绿植物引种条件初步分析当地的活动积温,结果表明,引种植物的积温需求应在4000左右,年生长周期在200天左右,这是决定引种植物能够健康成长,并在冬天到来之前新生枝条能够完成木质化确保安全过冬的关键因素之一。更多还原

【Abstract】 Temperature is one of the key factors affecting the success introduction of evergreen broadleaf plants.The temperature factors of Taiyuan from 2011 to 2019 have been analyzed according to statistics.This study analyzed the temperature factors of Taiyuan region in terms of days,quarters and years,including setting average temperature,maximum temperature and minimum temperature.The data proved that the high temperature in summer was generally less than 36 ℃,which is good for the evergreen broadleaf plants to grow up.The minimum temperature,however,was below-15 ℃ generally.This will be the key factor to limit the introduction plant selection.The semi-lethal temperature of the introduced plant should not be lower than-15℃,or necessary measures should be taken to prevent the frost damage of the introduced plant in winter in Taiyuan.According to the analysis of local active accumulated temperature in Taiyuan,the requirement of accumulated temperature should around 4000,and the annual growth cycle should around 200 days for selected plants,which is one of the key factors to determine the healthy growth of the introduced plants and the lignification of the new branches before the arrival of winter.更多还原
