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 6 0cm× 6 0cm× 6 0cm、重施基肥和追肥、造林密度为 16 6 7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。In this paper different soil type,site preparation,density,and fertilization were analysed.Results showed that the optional culture pattern was as follows:in hilly area yellow soil,site preparation standards were 60 cm×60 cm×60 cm,emphatically applying basic and additional fertilizer,and plantation density was 1 667 trees/hm 2,spacing in the trees and rows was 2 m×3 m.When rotation was 6～8 years,its economic results were 3.5 times of Pinus massoniana on the same site.It should be developed spreadly in the suitable site area of E.grandis .
