分析2011～2012年合浦县甘蔗新台糖22号3个“3414”肥料效应试验，结果表明，施肥处理均能显著提高甘蔗的产量和经济效益，产量比不施肥处理1(CK)增长17.0%～64.1%；经济效益增收0.30万～1.43万元/hm2。建立3个试验的肥料效应函数模型，综合得出甘蔗新台糖22号最高产量10.70 t/hm2、最高施肥量氮(N)530.0 kg/hm2、磷(P2O5)116.0 kg/hm2、钾(K2O)340.7 kg/hm2和最佳经济产量10.6 t/hm2、最佳施肥量氮(N)438.6 kg/hm2、磷(P2O5)110.9 kg/hm2、钾(K2O)272.9 kg/hm2。结合当地实际情况，总结出合浦县中低等肥力田块种植甘蔗新台糖22号的科学施肥配方为氮(N)450 kg/hm2、磷(P2O5)120 kg/hm2、钾(K2O)280 kg/hm2，施肥比例为N∶P2O5∶K2O＝1∶0.27∶0.62，产量10.59～10.70 t/hm2。

The effects of three "3414" fertilizer experiments on sugarcane cv. Xintaitang No. 22 in Hepu County in 2011~2012 were analyzed. The results showed that all fertilizer treatments increased significantly the yield and economic benefit. The yield increased 17.0%~64.1% than that of control (non-fertilizer treatment); and the economic benefit increased 3 000~14 300 yuan/ha. The function models of fertilizer effects of three experiments were made, comprehensively showing that the highest yield of sugarcane cv. Xintaitang No. 22 was 10.70 t/hm2, the highest fertilizer application quantities were N 530.0 kg/hm2, P2O5 116.0 kg/ha, K2O 340.7 kg/hm2; the optimum economic yield was 10.6 t/hm2, the optimum fertilizer application quantities were N 438.6 kg/hm2, P2O5 110.9 kg/hm2, K2O 272.9 kg/hm2. Based on the local conditions, the scientific fertilizer formula for sugarcane cv. Xintaitang No. 22 in the fields with medium fertility in Hepu County was N 450 kg/hm2, P2O5 120 kg/hm2, K2O 280 kg/hm2; N∶P2O5∶K2O=1∶0.27∶0.62, the yield was 10.59~10.70 t/hm2.
