Abstract: This paper aimed to explore the effect of N, P and K fertilization on chives, and establish a N, P and K fertilization model to provide a theoretical basis for the reduction of N, P and K fertilizers on chives. Based on the “3414” fertilizer model, the effects of different N, P and K application combinations on the growth, agronomic traits, yield, quality, fertilizer effect and utilization efficiency were studied through analyzing “Liujiang 3 chive”. The results showed that the contribution of N was greater than that of P and K. According to the yield, quality and fertilizer utilization rate, the best benefit of chive could be obtained when N, P and K were applied at N2P3K2 level （N 276 kg/hm2, P2O5 202.5 kg/hm2, K2O 270 kg/hm2）. The application rates of N, P and K were corrected by fitting function model and frequency analysis. When N（N） 197.41~255.98 kg/hm2, P（P2O5） 202.50 kg/hm2, K（K2O） 193.12~250.42 kg/hm2 （N∶ P2O5∶ K2O = 0.97~1.26∶1.00∶0.95~1.24） were applied, the economic and ecological benefits of chive were the best.

Key words: chive, "3414" model, yield, fertilizer effect, utilization ratio
