在泰国东北部Phonpisai土壤系列的一帕拉种植园的生长和碳储量进行了调查，包括1，5，10，15和20岁，和天然林。共15个40 × 40 m的样地用于研究橡胶生长，每个年龄级种植园三个样地，天然林一个样地。在每个样地中，测量了树的地上1.3m处的茎围、冠幅和高度。将各龄级种植园中平均生长量的橡胶树各取一株，分离出干、分支、叶、根生物量，建立异速生长方程。每个样地设15个土坑，沿土壤剖面沿着采集土壤样品。室内分析了土壤理化性质。橡胶树密度在80-109株/rai之间（1公顷= 6.25 rai）。干围和树高生长量随种植园的增加而增加。这些增长非常
Growths and carbon stocks in a series of para rubber plantations on Phonpisai soil series in northeastern Thailand were investigated including 1, 5, 10, 15 and 20 years old, and a natural forest. Totally 15, 40 x 40 m sampling plots were used for studying rubber growths, three plots per each aged class plantation and one plot for the natural forest. In each plot, stem girth at 1.3 m above ground, crown width and height of trees were measured. One rubber tree having the mean growth in each aged class plantation was cut and separated to stem, branch, leaf and root biomass for making allometry equations. Fifteen soil pits were made in each plot, and soil samples were collected along soil profile. Soil physical and chemical properties were analyzed in laboratory. Rubber tree densities varied between 80-109 trees/rai (1ha = 6.25 rai). Stem girth and height growths were increased with the plantation ages. The growths were very
