摘　　要：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 article, a certain experience has been gained in the seed collec-tion, seedling raising, afforestation and tending management in the link of domes-tication culture of Tsoongiodendron odorum. The biomass of aboveground organsof 10-year-old was determined by the stratified cutting method while the biomassof underground root system was determined by the ditch method. Results revealthat the 10-year-old stand biomass reaches 55. 03t/hm^2, of which the arboreousstorey reaches 53.04t/hm^2(accounting for 96.37%). In the arboreous storey, thebiomass of stems, branches, leaves and roots reaches 37. 91t/hm^2、6.17t/hm^2、2,21t/hm^2 and 6.75t/hm^2, respectively. The data of the 18-year-old analysis treeshow that the fast growing period of breast-height diameter, height and volumeoccurs in 4--12 years, 5--7 years and the 14th year, respectively.
