立地与混交模式对刨花楠幼林生长的影响

Site and Mixed Pattern Effects on Growth of young Plantation of Machilus pauhoi

以营造在建德市寿昌林场五年生刨花楠与杉木不同混交模式林及纯林为研究对象,对刨花楠不同立地条件下人工林生长差异以及与杉木混交后不同模式林分的生长量差异进行了研究。结果表明:不同立地条件下刨花楠幼林生长量差异明显;刨花楠与杉木混交后能促进刨花楠幼林的生长,其中以楠∶杉=2∶1混交模式刨花楠的生长量较高,与刨花楠纯林相比,平均树高和平均胸径分别提高了10.45%和12.71%,是一个值得推广的刨花楠混交造林模式。

Growth difference under different site of Machilus pauhoi plantation,and growth of different mixed pattern of 5-year-old Machilus pauhoi, Cunninghamia lanceolata, of Jiande City in Zhejiang Province were studied.The results showed that the growth difference was significant under different site.The mixed stand of M.pauhoi,C.lanceolata could promote the growth of M.pauhoi,the growth of the mixed pattern of M.pauhoi,C. lanceolata in the ratio of 2 ：1 was higher,at pure M.pauhoi stand for comparing,the average tree height and DBH improved 10.45% and 12.71% respectively,it was a good mixed afforestation pattern and worth to be extenuated.
