根据4年来对湿地松的采脂试验结果,11年生的树木已可用于采脂,24年生的林分具有旺盛泌脂能力和进入正常采脂。林木个体之间产脂量的差异相当大。江西以4～9月采脂为宜,间伐植株采脂割面负荷率可达80％。采脂后愈合能力强,如长期采脂割面负荷率以60％为宜。应选择高产脂优树,在立地条件较好的林地上营建长期采脂基地林。
According to the results of 4 years of experiment on the harvesting of Pinus elliottii, the 11-year-old trees can be used for collecting fat, and the 24-year-old stands have strong capacity of producing fat and enter normal fat-collecting. Differences in the amount of fat produced among forest individuals are significant. From April to September in Jiangxi Province, it is advisable to pick up fat, and the load-cutting rate of cutting fat-cutting face can reach 80%. Lipid healing ability, such as long-term fat cutting face load rate of 60% is appropriate. Should choose high-yielding resinous tree, in the site conditions better woodland to build long-term lipid-collecting base forest.
