木荷优质干材培育修枝技术的研究

Study on Pruning Technology for Cultivation of High Quality of Schima superba Timber Forest

对木荷林培育优质干材的修枝技术及效应进行了分析研究。结果表明:木荷早期较耐阴,萌芽性强,易发生副梢,分枝较密集,自然整枝能力差。作为用材林培育,应该采取适当的修枝措施。修枝适宜在5 a生左右进行,在休眠季采取中度修枝(修去冠长的2/6)。合理的修枝,有利于树高、树径和立木材积的生长,能够提高其干材质量。

The pruning technology for cultivation of high quality of Schima superba timber forest was studied.The results showed that it had shade resistance in the early stage.It was easy to sprout secondary shoot.The dense branches led to weak natural pruning.Therefore some measurements needed to be taken to cultivate high quality timber forest.Five years old plant was suitable for pruning.The branches should be moderately pruned during dormant period.The reasonable pruning was benefit for the growth of height,diameter and stumpage volume,and improving the quality.
