摘要: 探究氮、磷、钾施肥量对香葱的影响,建立氮、磷、钾施肥模型,为香葱化肥减施提供理论依据。基于“3414”肥料模型,以“柳江3号”香葱为试验材料,分析不同氮磷钾施用组合对香葱生长农艺性状、产量、品质、肥料效应及利用率的影响。结果表明,氮肥的贡献大于磷肥大于钾肥,综合产量、品质、肥料利用率等各项数据,当氮、磷、钾施用量处于N2P3K2水平(N:276 kg/hm2、P2O5:202.5 kg/hm2、K2O:270 kg/hm2)时,香葱可获得最优效益。通过拟合函数模型以及频率分析法修正氮、磷、钾施用量,当施用氮(N)197.41~255.98 kg/hm2、磷(P2O5)202.50 kg/hm2、钾(K2O)193.12~250.42 kg/hm2(N∶P2O5∶K2O=0.97~1.26∶1.00∶0.95~1.24)时,种植香葱可获得的经济效益及生态效益最优。

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
