摘　　要：在不同试验地开展杉木(Cunninghamia lanceolata)与红锥(Castanopsis hystrix)、闽楠(Phoebe bournei)、刨花润楠(Machilu spauhoi)和马褂木(Liriodendron chinense)混交林早期生长效应研究。结果表明,杉木生长量在贝江河林场和山口林场的不同混交模式间差异显著,在同一混交模式下不同试验地间亦有差异。初步筛选出红锥为适合与杉木混交的阔叶树种。在杉木+红锥混交模式中,杉木年均树高和胸径分别为1.33 m和2.06 cm,红锥年均树高和胸径分别为1.14 m和1.19 cm。Early growth effects of Cunninghamia lanceolata-Castanopsis hystrix,C.lanceolata-Phoebe bournei,C.lanceolata-Machilus pauhoi,C.lanceolata-Liriodendron chinense mixed plantations in different test sites were analyzed.Results showed that there were significant differences on growth of C.lanceolata in Beijianghe forest farm and Shankou forest farm among different mixed patterns,and there were also significant differences on growth of C.lanceolata in the same mixed pattern among different test sites.C.hystrix was suitable to plant with C.lanceolata.In C.lanceolata-C.hystrix mixed plantation,annual average tree height and DBH of C.lanceolata were 1.33 m and 2.06 cm,respectively,and average annual tree height and DBH of C.hystrix were 1.14 m and 1.19 cm,respectively.
