摘　　要：针对不同的土壤类型、整地、造林密度、施肥等栽培、管理措施分析,表明栽培巨桉应选择中厚层山地黄壤、整地规格为60cm×60cm×60cm,重施基肥和追肥、造林密度为1667株/hm2,即株行距为2m×3m。在轮伐期为6—8年时,其经济效益是同等立地条件下马尾松林分经济效益的3.5倍。宜在巨桉适生区大力发展。This paper analysed on different soil type,site preparation,density,and fertilization.Results have suggested that the optional culture pattern is as follows:hilly area yellow soil,site preparation standards is 60cm×60cm×60cm, emphatically apply basic and additional.fertilizer,and plantation density is 1667trees/ hm^2,spacing in the trees and rows is 2m×3m.When rotation is 6-8 years,its economic results is 3.5 times of Pinus massoniana On the same site.It should be developed spreadly in the suitable Site area Of E.grandis.
