摘　　要：采用"3414"田间肥效试验研究氮、磷、钾肥对甘蔗新品种海蔗22号(粤糖09-13)产量及经济效益的影响,通过肥料效应模型分析,获得合理推荐施肥量,为推广、指导甘蔗新品种海蔗22号合理施肥提供依据。结果表明:氮肥对海蔗22号产量影响最大,接着为钾肥和磷肥;氮磷钾互作效应表明中等水平更有利于肥效的发挥,N_2P_2K_2为最佳肥效配比;本试验条件下获得海蔗22号最高产量(94.7t/hm^2)施肥方案为N 631.7 kg/hm^2,P_2O_5 276.54 kg/hm^2,K_2O 478.29 kg/hm^2;最大经济效益(39487.09元/hm^2)施肥量为N 414 kg/hm^2、P_2O_5 216 kg/hm^2、K_2O 511.18 kg/hm^2,相应产量为92.3 t/hm^2。The ＂3414＂ fertilization field experiment was conducted to study the effects of different amounts of nitrogen, phosphorus, and potassium on the yield and economic benefits of the cane, and the optimal fertilization was analyzed by one-factor and three-factor fertilizer response model, which could provide the basis for the rational fertilization in the extension of new sugarcane variety Haizhe 22 （Yuetang 09-13）. The results showed that the influence on cane yield from high to low was N, K and P. The pairwise interactions indicated the fertilizer was more effective on the middle level and the best ratio of NPK was N2P2K2. The fertilization combination with the highest cane yield 94.7 t/hm2 was N 631.70 kg/hm2, P2O5 276.54 kg/hm2, and K2O 478.29 kg/hm2. The fertilization program resulting in the best economic benefit （39487.09 yuan/hm2） combination with cane yield 92.3 t/hm2 was N 414 kg/hm2, P2O5 216 kg/hm2, and K2O 511.18 kg/hm2 under the local experimental conditions.
