Plant overground part and underground part phenotype combined identification method based on root box

The invention relates to a plant overground part and underground part phenotype joint identification method based on a root box, the method is based on a crop phenotype information monitoring device, and the method comprises the following steps: filling nutrient soil into the root box, and placing the root box on a root box bracket; crop seeds are placed in a root box, and phenotypic data of crops are obtained when the seeds grow to a certain degree; the camera is connected to a computer end, and real-time images of crops are displayed on a screen; marking the acquired images of the overground part and the underground part; a Segform neural network training model is used to train the underground part; segmenting the overground part by using a U-Net method; predicting the image after model training to obtain a segmentation map of the underground part of the crop; predicting the image segmented by the U-Net method to obtain a segmentation map of the crop overground part; performing character extraction on the s
