摘要
调查了粤东沿海第一重山树种现状,结合近年来粤东地区沿海防护林造林树种生长表现情况,初步筛选了大头茶(Gordonia axillaris)、杨梅(Myrica rubra)、樟树(Cinnamomum camphora)、木麻黄(Casuarina equisetifolia)、台湾相思(Acacia confusa)、大叶相思(Acacia auriculiformis)、红荷木(Schima wallichii)和木荷(Schima superba)等8个树种进行了造林试验。结果表明:造林后2年,各树种平均保存率排序为:木荷(90.00%)>木麻黄(87.50%)>大叶相思(86.25%)>大头茶(85.00%)>红荷木(83.75%)>杨梅(81.25%)>樟树(80.00%)>台湾相思(76.25%)。大叶相思和木麻黄保存率高、生长快,可以作为粤东沿海第一重山造林先锋树种;木荷、大头茶、红荷木和杨梅4个树种保存率较高,可以作为伴生树种,适当进行混交造林。
Based on the investigation of the status quo of tree species in the first of mountains in the coast of eastern Guangdong province,this study combined with the growth and performance of tree species in coastal shelterbelt afforestation in Eastern Guangdong Province in recent years.The afforestation tests of Gordonia axillaris,Myrica rubra,Cinnamomum camphora,Casuarina equisetifolia,Acacia confuse,Acacia auriculiformis,Schima wallichii and Schima superba had been carried out for two years.The results showed that the average preservation rate of each tree species was as follows:S.superba(90.00%)>C.equisetifolia(87.50%)>A.auriculiformis(86.25%)>G.axillaris(85.00%)>S.wallichii(83.75%)>M.rubra(81.25%)>C.camphora(80.00%)>A.confuse(76.25%).A.auriculiformis and C.equisetifolia which had high preservation rates and fast growth could be used as the pioneer tree species for afforestation in the first of mountains in the coast of eastern Guangdong province.S.superba,G.axillaris,S.wallichii and M.rubra which had high preservation rates can be used as associated tree species for proper mixed afforestation.
