澳大利亚湿加松F_2代在广东早期生长表现

The Early Growth of Slash Pine × Honduras Caribbean Pine F_2 Hybrid from Australia in Guangdong Province

对广东省西江林场、银盏林场、通门林场、浸潭大树墩和龙坪林场等利用澳大利亚昆士兰F2代种子营造的湿加松幼林的生长状况和立地条件进行调查,分析幼林树高、地径或胸径生长与立地条件的关系。结果表明:在高温多雨的广东地区,F2代湿加松具有广泛的适应性。3年生时的树高及胸径分别比同年龄的湿地松大20.26%和27.27%。坡位、坡向、表土层厚度等因素对湿加松幼林的生长起着重要的作用。广东省的地理环境和气候状况适宜湿加松的生长。澳大利亚引进的F2代湿加松在广东省种植后生长情况较好,有着良好的发展前景。
