摘　　要：对邓恩桉人工林施用腐植酸桉树系列有机专用肥，进行林分生物量和生产力的试验研究，结果表明：在同等投入水平和基本相同立地条件下与施用常规化肥相比，施用专用肥的林分树高、胸径生长量分别提高了6．3％～26．6％，14．7％～37．2％，林分生产力提高了21．2％～44．1％。其中以每株施用腐植酸桉树基肥专用肥500g配合复合微生物菌剂10g作基肥＋腐植酸桉树追肥专用肥2号500g作追肥的林分生物量和生产力为最大，上述组合是适合福建北部地区邓恩桉林分的较佳施肥模式。We have approached the effects of Humic acid（HA） as organic fertilizer specially used in Eucalyptus on Eucalyptus dunnii stand biomass and productivity. The result showed that application of HA, compared with that of normally used chemical fertilizer, could get the tree height and OBH increased by 6. 3% - 26. 6%, 14. 7% - 37. 2% respectively, and the stand productivity increased by 21.2% - 44. 1%. Among several treatments, the combination of 500 g HA special basal munure, plus 10 g compound microbial inoculum with 500 g HA special additional munure （No. 2） each tree for 4 months after the former dressing could get the stand biomass and productivity maximal, suggesting its optimal dressing process in the Northern areas of Fujian.
