Method for evaluating content of heavy metal in vegetables based on soil conditions of production place

The invention discloses a method for evaluating the content of heavy metal in vegetables based on soil conditions of a production place. The method comprises the following steps: (1) planting the vegetables into one group of soil with relative known parameters, and detecting the content of the heavy metal in the vegetables after the vegetables are picked; (2) establishing a relation model between the relative parameters and the content of the heavy metal in the vegetables; (3) detecting relative parameters of soil of the production place of the vegetables to be detected, and evaluating the content of the heavy metal in the vegetables to be detected according to the relation model. By establishing the relation model between the relative parameters of the soil of the production place and the content of the heavy metal in the vegetables, detecting the relative parameters of the soil of the production place of the vegetables to be detected, and substituting the relative parameters into the model, the content of t
