对8种热带树木在韶关地区引种适应性的研究初报

摘要

通过对黄花风铃木等八个热带树种在韶关引种后的物候性、抗寒性和适应性进行系统的观察和比较后得知，黄花风铃木、海南红豆、海南黄檀和腊肠树这四个树种引种三年后的成活率可达到60％以上，同时抗性均较强，是适合在粤北地区引种的树种。%The phenology, hardiness and adaptability of 8 species of tropical trees, which were introduced to Shaoguan region in Guangdong Province,were investigated and analyzed. The adaptability of these species were preliminarily evaluated according to actual survival rate after three years planting. Results indicated that the survival rate of Tabebuia chrysantha, Ormosia pinnata, Dalbergia hainanensis and Cassia fistula among these 8 species were above 60%, which means it adapting to or basically adapting to the environment of north area of Guangdong.
