摘要
澳大利亚杂交松(Pinus elliottii×Pinus caribaea)引种区域对比试验表明,杂交松能适应广西的自然条件,并表现出优良的速生丰产性状。杂交松的生长优于马尾松、湿地松和加勒比松,其平均公顷蓄积量分别比马尾松、湿地松和加勒比松大34.93%、82.44%和174.98%。杂交松年均树高和年均胸径生长量都超过了广西马尾松速丰林生长指标,适于在生产中推广。
Regional testing for the hybrid pine introduction showes that it is adapt natural conditions in Guangxi with superior growth trait.Growth of the hybrid pines in Guangxi is better than Masson pine, Slash pine and Caribbean pine. Mean cumulation per hectare of the hybrid pine is more than Masson pine, Slash pine and Caribbeam pine by 34.93%, 82.44%, 82.44% and 174.98% .The annual mean height and DBH growth of the hybrid pine are better than that of Masson Pine fast growing plantation in Guangxi. The hybrid pine is adapt to extension in plantation.
