摘　　要：Fertilizer effect model such as ternary quadratic, unary quadratic, straight line and platform model was respectively used to analyze the two-year ＂3414＂ test data collected from banana garden in Fushan Town of Hainan Province. The results showed that the optimal fertilizing amount of ternary quadratic model simulation was0.374 kg/plant of N, 0.289 kg/plant of P2O5 and 0.891 kg/plant of K2 O. According to the yield trend characteristic, the optimal fertilizing amount of unary quadratic model was 0.400kg/plant of N, 0.214 kg/plant of P2O5 and 0.901kg/plant of K2 O. Thus it can be seen that only partial indices of the optimal fertilizing amount of ternary quadratic model simulation were higher than that of unary quadratic model. Considering the results, the optimal fertilizing amount of Brazil banana was 0.374-0.400kg/plant of N, 0.214-0.289 kg/plant of P2O5 and 0.891-0.901 kg/plant of K2 O.分别采用三元二次、一元二次和直线加平台等肥料效应模型,对海南省福山镇蕉园2年的＂3414＂试验数据进行分析。结果表明,三元二次模型模拟的最佳施肥量为：N 0.374kg/株、P2O50.289 kg/株、K2O 0.891 kg/株。根据产量趋势特点,对一元二次模型最佳施肥量为：N 0.400 kg/株、P2O50.214 kg/株、K2O0.901 kg/株。可见三元二次模型模拟的最佳施肥量只有部分指标高于一元二次模型。综合考虑试验结果,初步确定巴西香蕉最佳施肥量为：N 0.374~0.400 kg/株、P2O50.214~0.289kg/株、K2O 0.891~0.901 kg/株。
