Abstract: 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 economic 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.
