摘要:对山白兰幼林生长规律研究的结果为;(1)季节性生长节律,一年分为3个生长期,即滞生期(1~3月和11、12月),生长量较小或停缓;生长期(4~10月),生长迅速;高峰期出现在速生期中的6~8月,树高生长出现两次高峰(多为6月和8月),高峰期月生长量平均达20cm,胸径生长出现一次高峰,一般在5~8月,峰期生长量达0.11cm。(2)水热条件对树高和胸径生长量的相关关系均达显著程度;月平均温度对树高和胸径生长的影响较月降水量为大。(3)幼林的生长过程规律为;树高、胸径连年生长量高峰多在5a以前出现,高峰期树高连年生长量达2.61m,胸径达 4.2cm;7a后分别为1.0m和1.0cm左右。
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.
