| 摘 要： | 杉木是江西主要速生用材树种之一。通过对吉水县万华山林场20 a生人工杉木林分进行不同抚育间伐措施处理后,调查分析其平均胸径、平均树高、材种出材量、经济效益等存在明显差异。科学适时抚育间伐,经2次抚育间伐的杉木林分,上述因子高于经1次抚育间伐和未经抚育间伐的杉木林分,说明了抚育间伐能有效提高林分质量及经济效益。

| Abstract: | Cunninghamia lanceolata was a major species for fast-growing timber in Jiangxi.Through different thinning measures were made on 20 years old Cunninghamia lanceolata plantation in Wanhuashan forest farm in Jishui.Their average diameter at breast height,average tree height,timber volume of wood species and economic benefits were investigated and analyzed,which have significant differences.Thinning was made scientifically and timely,the land that with thinning for 2 times,the above factor were higher than that... |
