在福建尤溪和南平的3种地位指数林地上,对炼山和不炼山的1-5年生杉木幼林生长进行对比研究,结果表明.炼山对不同立地杉木生长的效应是不同的。炼山对14地位指数级林地1-5年生杉木幼林的生长有显著促进作用.但对18以上地位指数级林地杉木幼林的生长没有显著促进作用.
The effects of burning-slash and no-burning-slash treatments on the growth of 1- to 5-year-old Cunninghamia lanceolota plantations in Youxi and Nanping, Fujian Province were studied. The results showed that burning-slash had different effects on the growth of Cunninghamia lanceolota plantation in different site with different site index. Burning-slash could greatly promote the growth of 1- to 5-year-old Cunninghamia lanceolata in the site with 14 of index class, But there is no such effect in the site with over 18 of class.
