摘要
通过马尾松×木荷不同混交类型造林试验 ,及对早期营造的松荷混交林调查研究表明 ,松荷混交不但能改善林地土壤肥力 ,而且能明显促进马尾松的生长 ,提高林分生产力 ,是培育马尾松大径材的有效生物措施之一。但混交比例、配置方式及林分密度控制等是营造松荷混交林能否培育马尾松大径材林的关键技术措施 ;培育马尾松大径材林的松荷适宜混交模式为 :马尾松×木荷— 2松 1荷或 6松 4荷—星状或行带状混交—初植密度 2 5 0 0～ 312 5株·hm-2 —最终保留密度 80 0～ 12 0 0株·hm-2 。
Through the forestation experiment of different mixed type of P massoniana and S superba and investigation of the mixed stands that planted in early time,the results indicate that mixed stands of P massoniana and S superba not only improved soil fertilization but slso accelerated tree growth and raised productivity of forests. Mixed stand is one of efficienty biological way of cultivation big-Diameter timber of P.massoniana. Whereas mixed porportion and configurable fashion and management of forest density and so on, thoes are pivotal technique of cultivation big-Diameter timber of P massoniana by planting mixed stand of P massoniana and S superba. The suitable mixed pattern of cultivation big-diameter timber of P massoniana is P massoniana×S superba -2P :1S Or 6P :4S .-asteroidal or zonal mixedplanting density is 2 500 ～ 3 125 trees/hm 2-final retaining stand numbers is 800～ 1 200 trees perhm.
