Modeling method for prediction model of cadmium content in vegetables and application thereof

The invention belongs to the field of agriculture and environment, and relates to a modeling method for a prediction model of the cadmium content in vegetables and application thereof. The modeling method comprises the following steps that a soil sample is collected, the iron-extractable (FeDCB-soil) content of sodium hydrosulfite-trisodium citrate-sodium bicarbonate (DCB) in soil, the cadmium-extractable (Cdoxalate-soil) content of oxalic acid/ammonium oxalate (Oxalate) and the aluminum-extractable (AlNaoac-soil) content of acetic acid/sodium acetate (NaOAc) in the soil are measured, and a model relationship among the content of FeDCB-soil, Cdoxalate-soil and AlNaoac-soil and the content of vegetable cadmium (Cdplant) is established. The formula of the established model is shown in the formula. The model is suitable for the prediction of the cadmium content of the vegetables in the soil, can improve the prediction accuracy of the cadmium content of the vegetables, and provide reference for vegetable safety p
