广西国有黄冕林场21年生马尾松生长过程分析

Growth Process of 21-Year-Old Pinus massoniana in the State-owned Huangmian Forest Farm of Guangxi Zhuang Autonomous Region

通过对广西国有黄冕林场马尾松生长量的调查,选取标准木进行树干解析,分析马尾松直径、树高、断面积、材积的生长量,研究其生长规律。结果表明,该林场马尾松在前8年呈快速生长趋势,10~20年期间稳定生长,21年后生长缓慢,但还在生长,尚未达到马尾松的成熟期。

Through the investigation of the growth of Pinus massoniana in the state-owned Huangmian forest farm of Guangxi province , the standard standard wood was selected for trunk analysis, and the growth of the diameter, tree height, sectional area and volume of the Pinus massoniana were analyzed, and the growth law was studied. Result shows that Pinus massoniana shows a rapid growth trend in the first 8 years, stable growth during 10-20 years, slow growth in 21 years, but still growing, not yet matured in the cedar.
