桉树适应性广,生长迅速,经济价值高,目前已由一般的四旁植树转为成片上山营造速生丰产林;要使桉树上山造林成功,有几个技术问题值得注意。一、造林地的选择:桉树树干高大,主根深长,属深根性、强阳性树种。在选择造林地时,一定要选择土层深度在一米以上,上质疏松,背风向阳的坝脚缓坡地带造林。二、深耕整地:由于桉树根 Eucalyptus has wide adaptability, rapid growth and high economic value. At present, it has been converted from four-sided tree planting into fast-growing and high-yielding forests. To make eucalyptus afforestation successful, there are several technical problems worth noticing. First, the choice of afforestation land: tall eucalyptus trunks, the main root deep, is a deep root, strong positive species.
