Experiments and Selection ot Commercial Tree Species in Northern Zhejiang

Abstract: A forestation contrast of 41 tree species had been conducted on Hengfan Forest Farm of Lin'an County for 17 years, with the results that 16 tree species were eliminated because of extremely bad growth and low survival rate: that 5 species grew bushily with a low survival rate and bad growth; that 4 species grew ordinarily with survival rate being above 60% and that 16 species grew well with the survival rate being above 80%. Conifers such as Pinus taeda, P. ellitottii and P. serotina grew well, with the amount of growingstock per unit area for 17-year-old trees being 1.0-1.7 times as large as that of masson's pine. Of 3 varieties of Chinese fir, grey-shoot Chinese fir grew best. Of broad-leaved species Cinnamomum septentrionala, Sassafras tsumu, Choerospondias axillaris, Schima superba and Nyssa sinensis grew well, with the height, diameter at breast height and the amount of timber volume growth surpassing those of masson's pine on the same site, and the amount of annual timber volume growth per unit area being, on average, larger than that of masson's pine by 24.46%-65.96%. From the trial had come the result that the conifers and broad-leaved-species mentioned above showed great promise of development and extension on the hilly ground of northwestern Zhejiang.
