摘　　要：为了解澳大利亚湿加松(Pinus elliottii×P. caribaea)在广西中部引种的生长表现,在桂中地区的三门江林场对澳大利亚湿加松(P. elliottii×P. caribaea)与马尾松(P.massoniana)、加勒比松(P.caribaea)、湿地松(P. elliottii)进行造林对比试验,对其生长量、产脂量进行测定,试验结果表明:17.8a生时各树种的生长量为马尾松>湿加松>加勒比松>湿地松;在松脂产量方面,湿加松>加勒比松>湿地松>马尾松。湿加松早期生长快于其他树种,6.3 a生之后马尾松的生长量超过其它树种,17.8 a生时马尾松生长量显著高于湿加松、加勒比松和湿地松。从生长量和产脂量两个指标综合考虑,湿加松可作为脂材两用林进行培育。A comparing test on afforestation of Pinus elliottii×P.caribaea,P.massoniana,P.caribaea,and P.elliottii was carried out in Sanmenjiang Forest Farm of central Guangxi.Timber and resin yield were determined.The results showed that after 17.8 years of planting the growth ranked from high to low in order was P.massoniana,P.elliottii×P.caribaea,P.caribaea and P.elliottii,whereas the resin yield ranked from high to low in order was P.elliottii×P.caribaea,P.caribaea,P.elliottii,and P.massoniana.The growth rate of P.elliottii×P.caribaea was faster than other kinds of trees in early years.P.massoniana tended to have the fastest growth rate after 8 years of planting,and the growth of P.massoniana was significantly greater than P.elliottii×P.caribaea,P.caribaea,and P.elliottii after 18 years of planting.P.elliottii×P.caribaea could be used as timber and tapping resin forest in view of its timber and resin yield.
