摘要: 北美红杉在我国华东、西南几省引种已20余年。本次研究对在四川米易县引种的北美红杉无性系苗木的生长性状进行调查,发现植株生长健康,无病虫害,无明显的枯枝、枯梢,在海拔1480 m~1500 m间的萌蘖相对较多。数据分析表明,9 a生北美红杉在1480 m~1540 m的海拔内平均树高为3.35 m,平均胸径为5.52 cm;最好的单株树高为8.4 m,胸径为16.69 cm。将调查的结果与在昆明、贵州及原产地美国的生长状况进行对比的发现,美国红杉适应性强,在多个引种栽培点都能生长,但以昆明、贵阳等地生长较好。引种点不同生态环境(温度、水分和土壤环境)下美国红杉的生长状况分析结果表明,美国红杉不耐干旱的环境,在降雨量适中、湿度较大的温暖气候中的多种土壤上均生长良好,并且抗病性强,几乎没有病虫害。在四川凉山州安宁河流域、攀枝花米易等南亚热带湿润地区可引种栽培,作为园林绿化树种和珍贵工业用材树种培育。

Abstract: Sequoia sempervirens has been introduced for over 20 years in several provinces of Eastern and Southwestern China. In this study, investigations were made of the growth features of clonal seedlings of Sequoia sempervirens introduced in Miyi county, Sichuan province. The results displayed that the plants had a healthy growth, without diseases, insect pests, deadwoods or spike tops. There were more sprouts at the altitudes of 1 480 m~1 500 m. The data analysis result showed that the 9 years old Sequoia sempervirens had 3.35 m tree height and the average DBH of 5.52 cm at the altitude of 1 480 m~1 540 m. The best individual had the tree height of 8.4 m and DBH of 16.69 cm. Compared the growth condition in Miyi with that in Kunming, Guizhou and places of origin at United States, the results showed that the Sequoia sempervirens had a strong adaptability, and could grow in different introduced sites, but growing better in Kunming and Guiyang. According to the analysis of Sequoia sempervirens growth condition at each introduction point with different ecological environment (temperature, water and soil environment), the results showed that the Sequoia sempervirens could not adapt to drought environment, liked the soil in warm climate area with moderate rainfall and larger humidity, and it had a stronger insect resistance and could be introduced in south substropical areas such as the Anling River valleys and Miyi areas in Sichuan, and could be used as a garden greening and precious industrial timber species.
