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 34 years after planting;(3)there were two peaks of the tree volume increment,one in 6 years after planting with 0.023 4 m3,the other during 615 years.The tree volume quantitative maturity appeared during 1517 years after planting,at which the annul increment is equal to the mean increment.
