北美红杉在我国华东、西南几省引种已 2 0余年 ,其适应能力较强 ,在各引种栽培点都能生长 ,但以昆明、贵阳、舟山、都江堰等地生长较好 ,且都已开花结果。根据各引种点不同生态环境与北美红杉生长发育的关系 ,探索了该树种对温度、水分和土壤等环境条件的适应性。北美红杉在我国引种区对年均温 14～ 17℃ ,绝对最高温低于 40℃ ,绝对最低温不低于 - 10℃ ,年降水量 10 0 0～ 130 0mm ,年平均相对湿度 72 %～ 80 %的亚热带温暖和温凉、湿润和半湿润的气候环境比较适应。在红壤、黄壤或棕壤上都能生长 ,且抗病虫害能力较强。生态适应性研究为我国扩大其栽培范围提供了科学依据。
North American sequoia has been introduced for more than 20 years in several provinces of East China and Southwest China and its adaptability is strong. It can grow at all introduced cultivation sites, but it grows well in Kunming, Guiyang, Zhoushan and Dujiangyan, result. According to the relationship between the different ecological environments and the growth and development of Sequoia rubra at each accession, the adaptability of the species to environmental conditions such as temperature, moisture and soil was explored. North American sequoia in the introduction of the region of the average annual temperature of 14 ~ 17 ℃, the absolute maximum temperature below 40 ℃, the absolute minimum temperature of not less than -10 ℃, the annual rainfall of 10 0 ~ 130 0mm, the average annual relative humidity of 72% ~ 80% subtropical warm and cool, humid and semi-humid climate more suitable. In red soil, yellow soil or brown soil can grow, and strong resistance to pests and diseases. The study of ecological adaptability provides a scientific basis for our country to expand its cultivation range.
