A chlorophyll content prediction model for predicting chlorophyll content in the pericarp of Korla fragrant pears was constructed based on harvest maturity and storage time. This model predicts chlorophyll content in the pericarp of fragrant pears after storage by using the error backpropagation neural network (BPNN). generalized regression neural network (GRNN) and adaptive neural fu... https://powerlands.shop/product-category/solar-mounting/
