The invention provides a stress vegetation indicative information extraction method. The method comprises the following steps: building a stress vegetation indicative information extraction model based on a ViT framework; manufacturing a source domain sample and a target domain sample; dividing a source domain sample into a training set and a verification set as the input of the model; performing preprocessing operation on the input data; processing the preprocessed data through an FOPE module to obtain fragmented data, and performing zero value filling on a feature map; enabling the fragmented data to pass through a Transform encoder to obtain source domain coded data; taking a target domain sample as input data of the model, and repeating the steps of preprocessing, fragmenting, zero filling and coding to obtain target domain coded data; and calculating a difference value between the source domain and the target domain through an adaptive layer, adjusting the model, when the difference value is smaller than
