摘要
对海拔1100~1200m火炬松人工林生长及生物量的研究结果表明:21年生火炬松人工林生长良好,平均胸径、树高和蓄积量分别达15.8cm、12.8m和252m2/hm2,生长过程表现为速生期早、生长量大、持续期长,其数量成熟龄预计为25~30年,林分地上部分平均生物量为373.52t/hm2.
The studies on growth and biomass of Pinus taeta in area with elevation of 1100-1200m showed that 21-year-old Pinus taeta plantation grew well, its average diameter at breast height, height and volume of stand came to 15.8cm, 12. 8m and 252m ̄3/hm ̄2 respectively, the average biomass of stand above ground came to 373. 52t/hm ̄2. Pinus taeta in this area had such characteristics such as early fast-growing period, high increment and long sustained period, its quantitative maturity was predicted as 25-30 years.
