火炬松造林密度研究

Study on Afforestation Density of Pinus taeda

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.
