本文对观光木驯化栽培环节中的采种、育苗、造林、管抚等摸索了一定的经验,并用分层切割法测定10年生样本地上部分各器官的生物量,用壕沟法测定地下部分根系的生物量。结果表明:10年生林分生物量为55.03t/hm~2,其中乔木层为53.035t/hm~2(占96.37%),乔木层中树干、枝、叶和根系分别为37.91t/hm~2、6.17t/hm~2、2.21t/hm~2和6.75t/hm~2。18年生解析木数据表明:胸径、树高和材积速生期分别出现在4—12年、5—7年和第14年。
In this paper, the sightseeing wood domestication and cultivation of part of the mining, nursery, afforestation, pipe stroking and so on to explore some of the experience, and by stratified cut method for determination of 10-year-old plant aboveground biomass of each organ, with trenches method to determine the underground part of the root organism the amount. The results showed that the biomass of 10 - year - old stands was 55.03 t / hm ~ 2, in which the tree layer was 53.035 t / hm ~ 2 (accounting for 96.37%), the tree trunk, branch, leaf and root were 37.91 t / 2, 2.17 t / hm ~ 2, 2.21 t / hm ~ 2 and 6.75 t / hm ~ 2, respectively. The 18-year-old analytical wood data showed that the DBH, And the fourteenth year.
