A field test on N, P and K fertilizer efficiency was carried out in Huangjingui tea garden in An-xi. The results showed that applying N, P and K could increase the yield of tealeaves of spring tea by 15.4%, 6.1% and 9.3% and eco- nomic benefit by 12.8%, 5.0% and 8.1%, respectively. In addition, the optimal fertilization mode was N 20 kg/667 m2 （300 kg/hm2）, P2O5 7 kg/667 m2（ 105 kg/hm2） and K2O 7 kg/667 m2（ 105 kg/hm2）,and the proportion of them was N： P2O5： K2O = 1： 0.35： 0.35.
