摘要: 对湿地松人工林抚育间伐研究表明:在立地指数为14条件下15年生湿地松短轮伐期纸浆材的最佳经营密度为1800~1650株/hm2;建筑材最佳经营密度为1350~1200株/hm2,15年生后,应立即进行第二次间伐。Abstract: Study on tending and intermediate cutting in slash pine plantation proves that:on the condition of 14 site index, the best management density of short cutting cycle in slash pine plantation for pulpwood is 1 650~1 800/hm2 at the stand age of 15-year-old,and that for construction timber is 1 200~1 350/hm2,15 years later the second intermediate cutting should be carried out in time.
