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.
