摘要： 为了探索引进加拿大红枫的可行性，从加拿大引进了加拿大红枫种子，开展了其实生苗繁育、移栽成活率、青枫作砧木嫁接繁殖等研究，测量了1年生实生苗的株高与地径，并对其引种适应性进行了6年观测。结果表明，加拿大红枫种子的出苗率为55.7%，移栽成活率为95.6%。乡土树种青枫与加拿大红枫嫁接的亲和性较好，嫁接成活率达94%，但从第2年开始膨大，产生嫁接瘤，表明青枫不适合作砧木嫁接加拿大红枫。1年生实生苗的平均株高为116.2 cm，平均地径为1.1 cm。加拿大红枫适应性强，能顺利越夏，虫害可防可控。根据气候相似原理和有关引种报告，还论述了在中国长江流域及其以北地区适宜引种加拿大红枫。

Abstract: The seeds of red maple (Acer rubrum L.) from Canada were introduced to study the feasibility of introduction. The breeding technology, including seedling cultivation from seeds, survival percentage of transplant and the rootstock were studied. The plant height and the ground diameter of one-year-seedlings were tested. And more, the adaptability of red maple was investigated for the last 6 years. It showed that the germination rate of red maple seeds was 55.7% and the survival percentage of transplant of one-year-seedlings was 95.6%. If the native Acer serrulatum Hayata acted as the stock of red maple, the grafted tumor came out in the third years. The native Acer serrulatum Hayata was not suitable as the stock of red maple, although the survival percentage was 94% . The plant height and the ground diameter of one-year-seedlings were respectively 116.2 cm and 1.1 cm, respectively. Red maple showed a high adaptability and survives from the summer. The native insect pest of red maple was easily controlled. According to theory of climatic analogues and some introduction reports, it was concluded that Yangtze River Basin and the north of it was suitable for red maple introduction.
