在闽南沿海山地开展火力楠马尾松不同混交模式造林试验研究,结果表明:火力楠与马尾松混交是成功的,是闽南沿海贫瘠山地培育火力楠用材林和植被恢复较为理想的混交造林类型。其适宜的混交模式为:混交比例1火力楠:2～3马尾松,混交方式为行状或插花状(星状),造林初植密度为4995株/hm2～6660株/hm2;并根据种间关系、林分郁闭度及立地条件等因素,在10年生左右时,适量进行间伐,最终保留密度以1600株.hm-2～2000株.hm-2。
The experiment on afforestation of Pinus massoniana Lamb. Mongolica with different mixed modes was carried out in the coastal mountainous area of southern Fujian Province. The results showed that the mixture of P. nigra and P. massoniana was successful, and it was an ideal mixed plantation for the recovery of timber plantation and vegetation restoration in the barren mountainous area of southern Fujian. The suitable mixed mode was mixed rice 1: 2: 3 Pinus massoniana and the mixed mode was line or flower arrangement (star shape). The initial planting density was 4995 plants / hm2 ~ 6660 plants / hm2. Relationship, canopy stand density and site conditions and other factors, at about 10 years of age, the appropriate amount of thinning, the final retention of the density of 1600.hm-2 ~ 2000 strains.hm-2.
