闽楠人工林的经营效果

对闽楠人工林经营效果的研究结果表明:闽楠苛求立地,应选择Ⅰ、Ⅱ级立地的中下坡造林,闽楠适宜营造纯林,但应适时间伐,严格控制经营密度,20 a后经营密度不宜大于900株.hm-2。闽楠与杉木混交造林,种间关系难以调控,闽楠纯林比楠杉混交林中的闽楠生长好,若要营造混交林,应控制经营密度,杉木的混交比例不应大于30%。

Management effect of artificial forest of Phoebe bournie in Fujian

Study on the management effect of artificial forest of Phoebe bournei(Hemsl.) Yang showed that P.bournei was strict with standing condition,so it was proper to select downhill afforestation for the I,II class standing.P.bournei was fit to build pure forest,which must be chopped timely and its management density must be strictly controlled.The management density of P.bournei forest could not surpass 900.If P.bournei was mixed with Chinese fir,it would be difficult to coordinate the inter-species relationship.The pure P.bournei forest grew faster than the mixed one,and suited to build pure P.bournei forest.If mixed afforestation was adopted,the ratio of Chinese fir would be reduced and could not surpass 30 percent.
