| Abstract: | The data from 36 temporary plots and 25 fixed plots of 17~25 years old Cunninghamia lanceolata plantation in the north of Fujian Province were used to study the influence of site,age,and reserved density mean DBH and mean tree beight on the change law of out put of wood sort for C.lancelata.The results showed that the dominant factor influencing the formation of middle and small dimension wood was site,followed by reserved density and cultivation duration.It is suitable to cultivate middle dimension wood when the site index is no less than 16,the reserved density is 1 000~1 400 trees per hectare,and the age of tree is between 20~25 years old. |
