为探索永安地区桉树速生丰产的营林抚育技术，通过采用随机组合，对2010年造林的巨桉桉树林设计了控草和施肥量不同的抚育组合：试验结果表明，对桉树林实行控草和施放肥料有利于促进林木生长，提高林分生物量和生产力；同时通过经济效益分析表明，在永安地区桉树林的最佳施肥量为底肥施放0.5kg桉树专用肥+0.5kg钙镁磷（永安地区土壤缺磷元素），当年追施一次0.25kg桉树专用肥，次年追施一次0.25kg桉树专用肥；控草方式以人工控草为主，有条件的林地实行化学除草，特别是五节芒等恶性杂草较多的山场优先考虑进行化学除草。

For exploring the forest tending technology of fast-growing and high-yield of Eucalyptus in Yong'an area,by adopting random combinations to design the different nurturing combinations of weed con-trol and fertilizing amount to the afforestation of Eucalyptus grandis in 2010. The results show that artifi-cial control of the weed and fertilizer for Eucalyptus forest is beneficial to promote the growth of trees,im-prove the forest biomass and the productivity. Meanwhile,the further analysis of economic benefit indicate that the best fertilizer rates to Eucalyptus forest in Yong’an area is recommended 0.25kg fertilizer for Eu-calyptus+0.25kg calcium magnesium phosphate(Yong An regional soil are deficiency of phosphorus) as base fertilizer, then the Eucalyptus have to be topdressing 0.15kg fertilizer for Eucalyptus on the same year and 0.25kg fertilizer for Eucalyptus on the second year. Artificial control should be the primary way for the weed control,forest where conditions permit should implement chemical weed control.
