摘　　要：2012年在合浦县沙岗镇进行柳城03—182测土配方施肥"3414"肥效试验,以N2P2K2处理的产量最高,为104583.0kg/hm2。根据肥料互作效应分析结果:N、K、P互作效应为NPK>NK>NP>PK;单元素对产量的作用效果是N﹥K﹥P。应用回归方程分析结果:合浦县中低等肥力田块种植甘蔗新品种柳城03—182的最佳施肥量为N 549.3kg/hm2、P2O5143.6kg/hm2、K2O 497.7kg/hm2,最佳产量为106402.1kg/hm2。A fertilizer effect experiment of soil -tested and formula fertilization ＂3414＂ of new sugarcane variety Liucheng03 - 182 was conducted in Shagang Town, Hepu County in 2012. The treatment of N2P2K2 has the highest yield： 104583.0 kg/hm^2. Based on the analysis of fertilizer interaction effect, the interaction effect of N, K, P will be NPK 〉 NK 〉 NP 〉 PK, for single element, the interaction effect order will be N 〉 K 〉 P. For application of Regression Equation analysis results, in middle and lower fertility farmlands, the best application amounts for this new variety in Hepu are N 549.3 kg/hm^2, P205 143.6kg/hm^2 and K20 497.7 kg/hm^2 with the yield of 106402.1 kg/hm^2.
