| 摘 要： | 通过闽中山地 2 1～ 2 2年生的湿地松、火炬松、马尾松生长过程的研究表明 :在一般经营条件下 ,湿地松 2 1年生材积可比马尾松高 2 3 8% ,火炬松介于湿地松与马尾松之间。国外松胸径、树高在 8年生前为速生期 ,材积在前 14年生为速生期 ,持续时间短 ,18～ 2 0年生达数量成熟。马尾松的胸径速生期在 14年生 ,高生长的速生期在 14～ 16年生 ,材积在 2 0年生为速生期。

| Abstract: | The study reveals that under the common management conditions,the volume of 21-year-old Pinus elliottii is 23.8% higher than that of P.massoniana and the volume of P.taeda is between that of P.elliottii and that of P.massoniana.The dbh and height of foreign pines before the age of 8 are in the fast-growing period,their volume before the age of 14 is in the fast-growing period,the time of duration is short and it reaches the quantitative maturity at the age of 18～20.The fast-growing period of P.massoniana dbh,height and volume is at the age of 14,14～16 and 20 respectively. |
