麻栎 马尾松天然次生混交林生物量结构及根系分布特征调查研究

The investigating and study to the natural secondary mixed forest's biomass and the root system's spreading character of the oak and the horse-tail pine

通过对马尾松、麻栎天然次生混交林林分生物量的测定,对林分生物量积累、根系分布特征的差异进行了研究。结果表明,两类树种混交造林方式能在一定程度上提高树干的生产量,天然次生麻栎较马尾松具有主根、水平根系均发达,且须根分布均匀的特点。

Through measuring the natural secondary mixed forest's biomass ,we studied the diversity of the accumulation of the forest stand biomass and the distribution feature of the root system. The survey indicate that the two different woods were mixed planted together can improve the production of the trunk ,and the natural secondary oak has showed more characteristic than the horse-tail pine such more reasonable etc.
