桐棉马尾松不同密度的间伐强度试验初报
The Preliminary Report on the Intermediate Cutting Intensity Experiment of Different-Density Tongmian Masson Pine
【摘要】 桐棉马尾松密度试验林间伐试验结果表明 ,间伐能显著促进不同密度林分胸径生长 ,随着间伐强度加大 ,胸径定期生长量增大 ,间伐对树高影响不显著 ,蓄积量和总蓄积量均随间伐强度加大而降低
【Abstract】 The intermediate cutting experiment results of Tongmian Masson pine density experiment forest indicate that the intermediate cutting can evidently promote the DBH growth of different density stands;the periodic increment of the DBH increases with the increase of the intermediate cutting intensity;the influence of the intermediate cutting on the height is not obvious;and both stocking and total stocking reduce with the increase of the intermediate cutting intensity.
