摘要：应用广西大青山2～26年生米老排人工林试验样地数据和树干解析木资料，研究其幼林生长节律及与气候的关系，以及成熟林的生长规律。研究结果表明：（1）米老排幼林生长的季节变化呈双峰曲线，5月和9月生长量最大，月生长量与月均气温相关性显著；（2）早期速生特性明显，胸径、树高连年生长和年均生长高峰均在3～4年生时出现，且高速生长期持续较长；（3）材积生长伴随树高和胸径的快速生长后，于6年生时出现第1次生长高峰，连年生长量达0．0234m^3；6～15年生材积年生长量最大，15～17年生平均生长量达最高峰，并与连年生长量曲线相交，因此确定此林龄为材积生长的数量成熟龄。
Based on the data collected from the experimental sample plots and investigation sample plots, including analytical trees at age of 2 to 26 years in Daqingshan, Guangxi, the growth rhythm of young plantation of Mytilaria laosensis and its correlativity to the climate, the growth process of the matured plantation were analyzed. It was indicated that （ 1 ） the monthly rhythm showed two growth peaks respectively in May and September, and monthly increment of height and diameter breast height （DBH） was remarkably correlated with the mean monthly temperature ; （2） the tree species grew quickly in its early stage, with the growth peak of its annual increment of tree height and DBH appearing in 3- 4 years after planting; （ 3 ） there were two peaks of the tree volume increment, one in 6 years after planting with 0.023 4 m^3 ,the other during 6 - 15 years. The tree volume quantitative maturity appeared during 15 - 17 years after planting, at which the annul increment is equal to the mean increment.
