摘要: 根据89个水稻氮磷钾田间试验结果,认为三元肥效模型是否属于典型式取决于模型极值存在与否和极值性质。依据极值判别结果,可将三元肥效模型分为典型式和三种不同类型的非典型式。分析了不同类型三无效模型的施肥意义和极值判别方法,并对非典型式提出了施肥建议

Abstract: According to 89 trials on N,P, K in paddy field, it was suggested that the typicality of three-fertilizer efficiency model was desided by the existence and the character of extreme value.Based on the distinguished results of extreme value,three-fertilizer efficiency model may be clas-sified as typical model and three types of non-typical model,The character of different types of three-fertilizer efficiency model and the distinguish methods were analysed, and the recommenda-tory fertilization for non-typical model was contributed in this thesis.
