摘要
整地施肥试验结果表明，全垦、带垦和穴垦３种整地方式及施肥对尾叶桉造林成活率和保存率均没有明显的影响．这３种整地处理加上施肥，对促进尾叶桉生长均能取得理想的效果，５年生材积，施肥是不施肥的９．８倍．全垦和带垦整地虽然在一定程度上促进了林木的生长，但在贫瘠的立地上，加施肥料才能达到速生丰产经营目的。整地和施肥间的交互作用不明显．施肥对尾叶桉的促进作用可延至５年以后。
An experdrient of the fertilhation and site preparation methods and growth responses for Eucalyptus urophylla was carried out in Huadu, Guangdong Province. The result showed that there were no sighficant effects by the use of different site prepeation methods (complete, belt and spot-ploughing) on the survival. Whilst the growth responses to fertilization with these three method of site prepations were clearly demanstrated in the trials, but at the poor site, only fertilising Could produce a significant growth response. The reciprocity effect between fertilization and site prepeation was hardly detected. The fertilization was responsible to increasing growth for five years or even more.
