木荚红豆生态学特性及育苗造林技术

Research on bio-ecological characteristics,cultivation and afforestation techniques of Ormosia xylocarpa

通过对武夷山天然木荚红豆(Ormosia xylocarpa)的生态学特性、物候期观察,确定木荚红豆的合理种子采收期,同时开展种子育苗、人工造林和丰产管理技术的研究试验.结果表明:木荚红豆的合理种子采收期应在11月以后;木荚红豆种子播前处理的最佳方法是采用温水浸泡24h;提高造林成活率的技术是让苗木充分本质化并切除过长的主根;丰产管理技术关键在于保护林木顶芽(主干)减少分杈,才能提高阔叶树的出材率.

A reasonable period for harvesting seed of Ormosia xylocarpa was identified by observing bioecological characteristics and flowering phenophase of Ormosia xylocarpa in Mount Wuyi. Research on artificial plantations; nursing of seeding and high-yield management techniques were carried out. The result shows that a reasonable period for harvesting seed of Ormosia xylocarpa was after November. The best way to treat the seeds before planting was immersion of them 24h under warm water. Techniques of improving survival rate were lignifications and removal of long taproot. The key to high-yield management techniques were protecting the trunk and reducing branching. Only in this way can outturn rate of a broadleaf tree be improved.
