【 摘 要 】

The amount of carbon dioxide (CO2) fixed by the perennial tea thee during the growth period was estimated from actual measurements and from data in the literature. CO2 fixed by 2-year-old young trees was 28.8 g per plant and 53.5 kg per 10 a. The amount of CO2 fixed by adult trees varied depending on whether the stems welle cut off for rejuvenation or not, and immediately after cutting, the amount was 3.9 kg per plant and 7.3 t per 10 a. In the year of usual tea picking, the amount was 6.3 kg per plant and ll.6 g per 10 a. Compared with fruit trees such as peach and pear trees, the planting density of tea trees was higher suggesting that the amount of CO2 fixed by the tea tree was larger than that fixed by fruit trees, but the amount was less than that fixed by a forest of equal area.
