马尾松天然林更新容易.由于林分密度大,郁闭时间早,自然分化严重,应及时进行经营调节,促使林分质量提高.我们对不同密度的马尾松天然次生林的间伐强度进行试验,经3年观测,得出密度在4000——6000株/ha的林分间伐强度以株数的40—50%时,效果最佳的初步结论. Masson natural forest regeneration easier.As the density of the forest, the early canopy closing time, the natural differentiation is serious, should be timely adjustment of management, to promote the quality of the stand.We have different density of natural secondary forests of Masson pine thinning strength test, the 3 years of observation, come to the initial density of 4000 - 6000 plant / ha in the thinning intensity of the number of trees to 40-50%, the initial results of the best.
