【摘要】 在马尾松林下进行南酸枣、毛红椿、山杜英、青冈、无患子、珊瑚朴、枫香、刨花楠、木荷直播造林试验,调查其发芽率、发芽势、树高与地径,结果表明:不同树种间直播发芽率存在显著差异,南酸枣、青冈、刨花楠比较适合直播造林,木荷、枫香、珊瑚朴直播造林效果不理想;在直播造林情况下,不同树种的树高、地径生长也存在极显著差异,树高生长以刨花楠和青冈较好,地径相对生长量以青冈和无患子效果较好。综合各种因素,青冈、刨花楠和无患子可以作为针叶林下阔叶树直播造林的树种选择。更多还原

【Abstract】 Experiment was carried out on plantation of Choerospondias axillaries,Toona ciliata var.pubescens,Elaeocarpus sylvestris,Cyclobalanopsis glauca,Sapindus mukorossi,Celtis julianae,Liquidambar formosana,Machilus pauhoi,Schima superba by direct seeding under Pinus massoniana forest in Zhejiang province.The result showed that germination rate of the experimented tree species had difference.It showed that Ch.axillaries,C.glauca and M.pauhoi was suitable for the plantation while S.superba L.formosana and C.julianae was not.Meanwhile,seedling height of M.pauhoi and C.glauca and rhizome diameter of C.glauca and S.mukorossi had the best.The experiment showed that C.glauca,M.pauhoi and S.mukorossi could be selected for the direct seeding tree species under coniferous forest.更多还原
