摘　　要：在福建南平对炼山和不炼山的第2代5年生杉木幼林生长进行对比研究,结果表明,2种处理杉木平均胸径年均生长量均在1.70 cm以上,平均树高年均生长量均在1.00 m以上;炼山处理杉木的生长量略高于不炼山,但它们之间的差异不显著。The effects of slash burning and no slash burning treatments on the growth of 5-year-old, second rotation Chinese fir plantations in Nanping, Fujian Province were studied. The results showed that mean annual increment of DBH was over 1.70 cm, and mean annual increment of tree height was over 1.00 m in both of the treatments. Tree growth in slash burning treatment was slightly higher than that of no slash burning treatment, but the difference was not statistically significant.
