摘要： 研究提出了落叶果树“低量、适量、过量”叶片不同营养状态的隶属函数，定义出散漫化语气算子和判定化语气算子，以最大隶属度原则为依据，建立了落叶果树营养诊断的模糊模型和用于苹果、梨诊断的有关参数。计算分析表明，在用于桃、葡萄等树种时，对有关参数进行修正，此模糊诊断模型适用于落叶果树的营养诊断。

Abstract: In this paper the authors suggested the subordinate function of deficient, normal and excessive nutrition states in the leaves of deciduous fruit tree defined discrete operator and decision operator, and formed fuzzy diagnostic model of mineral nutrient content in deciduous friut tree. according to maximum subordination principle.The result indicated that the model was also suitable for peach and grape by introducing proper parameter,and this fuzzy diagnositic method can be used for other deciduous friut tree.

Key words: Deciduous fruit tree, Nutrient diagnosis, Subordinate function, Fuzzy model, Operater
