在福建省南平峡阳国有林场开展5种不同立地管理措施对1片29年生第1代杉木人工林采伐后营造的5年生第2代杉木人工林生产力影响的研究结果表明,BL3(收获树干和树皮、加倍采伐剩余物)处理的5年生2代杉木林生长最好,其次为SB(收获树干和树皮,炼山)处理和BL2(收获树干和树皮,不炼山)处理,BL1(全树收获)和BL0 (移走地上所有有机残留物)处理杉木生长最差。除了BL3与BL1处理的树高生长量差异显著外,其余任何处理间杉木生长指标的差异均未达到统计上的显著水平。
Five different site management measures were carried out in Xiaoping National Forest Farm of Nanping, Fujian Province. The results of the study on the impact of the second-generation Chinese fir plantation productivity after cutting on a 29-year-old first-generation Chinese fir plantation showed that BL3 Bark and doubled cutting residues), followed by SB (Harvested Trunk and Bark, Refining Hill) and BL2 (Harvested Trunk and Bark, Not Refined), BL1 (Full tree harvest) and BL0 (removal of all organic residues on the ground) were the worst. Except for the significant difference in tree height growth between BL3 and BL1, no significant difference was found between the growth indexes of any other treatments.
