The study designed a diversified cultivation path for gardening talents based on the “integration of education and training”. A three-level comprehensive evaluation index system is constructed from the dimensions of the “teaching” path and the “education” path. On this basis, a comprehensive evaluation model based on Bayesian network was established to analyze the role of indicators, construct subjective and objective evaluation sub-Bayesian networks, and form a comprehensive evaluation Bayesian network. After validation, the overall accuracy of the model reached 81.3%. The model was used to analyze the diversified training path of garden talents based on the design of “integration of education and education”, and the overall satisfaction of the path was high, and the probability of evaluation as “excellent” was as high as 92%, but there was still room for improvement in the “teaching” path. For this reason, this paper further optimizes the diversified cultivation path of gardening talents through precise disciplinary positioning, clear guiding ideology and formulation of professional curriculum system.
