摘　　要：为取得有关施肥参数,建立超级稻施肥模型,应用"3414"设计方案对超级稻两优培九进行田间肥效试验,研究不同配方施肥对其产量的影响。结果表明,氮、磷、钾配施,以施肥量高的处理产量相对较高;在一定范围内,氮、磷、钾肥的施用量对超级稻的增产作用是氮肥大于钾肥,钾肥大于磷肥。建议玉林市超级稻氮、磷、钾施用量分别为N 240.0kg/hm2、P2O590.0kg/hm2、K2O 255.0kg/hm2。同时要掌握好施肥时期和比例,特别是后期适宜施氮,保证超级稻各个生长期所需氮素。In order to obtain the parameters and model of fertilization for super rice, the fertilizer experiment for the super rice Liangyou Peijiu was conducted by ＂3414＂ design in field. The results showed that, when combined with N, P and K, the yield in the treatments with high amount of nitrogen, potassium and phosphorus was higher, and nitrogen fertilizer had the highest effect on yield increasing when the N, P and K was at a certain level, compared to potassium and phosphorus fertilizers. Application of nitrogen （N） 240. 0kg/hm^2, potassium （KZO）255.0kg/hm^2 and phosphorus （P2O5） 90.0kg/hm^2, respectively, for the super rice was recommended, and the fertilization stage and ratio should be properly controlled. Particularly the nitrogen should be suitably fertilized at later stage to provide the nitrogen needed at all duration by super rice.
