摘 要:在闽南地区对沉香、桢楠、红锥、闽楠等4种珍贵树种进行造林试验,结果表明:造林9个月的生长量总体表现为沉香>桢楠>红锥>闽楠,在树高生长上桢楠与沉香间不存在显著性差异,其他两者之间均存在显著性差异;而在地径生长量上,红锥与桢楠、红锥与沉香间不存在显著性差异,桢楠与闽楠、桢楠与沉香、红锥与闽楠、沉香与闽楠均存在显著性差异。造林14个月的生长量体现为红锥>沉香>桢楠>闽楠,在树高生长量上红锥与沉香树不存在显著性差异外,其他两者之间均存在显著性差异;而地径生长量,除桢楠与闽楠生长量不存在显著性差异外,其他两两之间均存在显著性差异。红锥在该地区适应性强,生长快;桢楠和沉香生长趋势也较好;作为乡土树种闽楠则在生长量上表现较差。Afforestation experiments on four precious tree species in southern Fujian were conducted.Result shows that the growth of afforestation for nine months is as follows:Aquilaria sp.>Phoebe zhennan>Castanopsis hystrix>Phoebe bournei.There is no significant difference between Phoebe zhennan and Aquilaria sp.in tree height growth,and there is significant difference between the other two.There is no significant difference between Castanopsis hystrix&Phoebe zhennan,Castanopsis hystrix&Aquilaria sp.in growth of ground diameter.Phoebe zhennan and Phoebe bournei,Phoebe zhennan and Aquilaria sp.,Castanopsis hystrix and Phoebe bournei,Aquilaria sp.and Phoebe bournei have significant differences.The growth of afforestation for 14 months is reflected as:Castanopsis hystrix>Aquilaria sp.>Phoebe zhennan>Phoebe bournei.There is no significant difference between Castanopsis hystrix and Aquilaria sp.in growth of tree height;there is a significant difference between the other two.In terms of the growth of ground diameter,there is no significant difference between the growth of Phoebe zhennan and Phoebe bournei,and there are significant differences between the other two.In general,Castanopsis hystrix is highly adaptable in the region,and it grows fast.The growth trend of Phoebe zhennan&Aquilaria sp.is also optimal,while the native tree species--Phoebe bournei performs poorly in growth.
