摘　　要：以闽南地区长泰县金公山柚木基地的1a生和2a生柚木及闽南地区的厦门天竺山柚木基地的2a生柚木为试材,分别进行了N、P、K肥效试验和EM肥效试验。结果表明:N、P、K肥效试验中,以每公顷施N 133.3kg、P 333.3kg和K 66.7kg对柚木的生长促进最为明显,以每公顷施N 66.7kg、P 33.3kg、K 66.7kg对柚木生长促进最差;EM微生物复合肥施肥试验中,15%的EM肥浇灌效果最好,其次为10%的EM肥浇灌,5%EM肥浇灌和5%叶面施肥对柚木的生长促进并不明显,但5%叶面施肥优于5%浇灌。在对闽南柚木栽培时,可选用N2P6K1的最佳N、P、K配比进行施肥,并要注意磷肥的施用;施EM微生物复合肥时,可用15%的EM肥进行浇灌。Taking Tectona grandis of 1 year old and 2 years old in the Tectona grandis base of Changtai Jingong mountain in the south of Fujian and Tectona grandis of 2 years old in the Tectona grandis base of Tianzhushan Xiamen in the south of Fujian as materials,N,P,K fertilizer effieiency experiment and EM fertilizer efficiency experiment were tested. The results showed that the treatment N 133. 3 kg,P 333. 3 kg,K 66. 7 kg each hectare had obvious promotion on the growth of Tectona grandis ;the treatment N 66. 7 kg,P 33. 3 kg,K 66. 7 kg each hectare had the worst promotion on the growth of Tectona grandis;in the EM fertilizer effieieney experiment, 15% EM had the best effect,followed by 10% watering,5% watering and 5% foliar fertilization,5; foliar fertilization better than 5% watering. In the cultivation of Tectona grandis in the south of Fujian, N2P6 K1 could be chosen to fertilizer, and adding phosphate; when applying MS microbial compound fertilizer, 15% EM watering was better.
