| Abstract: | In this paper, the seasonal growing rhythm of height and diameter breast height (DBH) for Paramirhelia builonii and the growing regularity during the period of the young plantation about 10-year-old were conducted. Growth rhythm during a year is divided into stagnant stage,growing stage and summit. The stagnant stage is front january to March and November to December with monthly increment near zero. The growing stage is from April to October during which the stage of growing summit appears two times for height growth and once for DBH increase front May to August. The two summits for height growth appeared in June and August with monthly increment of 20 cm. The summit for DBH in crease comes during May to August with monthly increment of 0. 11 cm. The summit of the annual increment in height and DBH appeared before the age of 5 years old with an annual increment of 2. 6 m in height and 4. 2 cm in DBH. After the age of 7 years old ,the increment fell below 1. 0 In and 1. 0 cm in the height and DBH respectively in the successive years. |
