摘要
在我国中、北亚热带丘岗地区， 营造工业用材林宜以火炬松为主， 适当兼顾湿地松材、脂兼用林， 造林密度以１ ６６７ 株／ｈｍ ２ 为宜， 部分较优立地或高规格整地区可考虑１３３３ 株／ｈｍ ２， 部分较差立地可考虑２ ０００ 株／ｈｍ ２， 首次间伐宜在１０～１２
In the hilly ground within the middle and north subtropic zone of China,afforestation for industrial timber should be dominated with Pinus taeda,and forest of Pinus ellottii and forest for pine tree resin should be considered appropriately as well.Afforestation density of 1667 plant/hm 2 should be considered for commond ground,1333 plant/hm 2 for some part of high quality ground or high grade prepared zone,and 2000 plant/hm 2 for some part of poorer ground.The first time intermediate cutting can be carried out in 10～12 years.
