Abstract
A crop irrigation method based on a salt leaching fraction disclosed. The method includes: calculating a salt leaching fraction of crops by combining a salt stress and effect of water quality on an irrigation amount of the crops, controlling an irrigation apparatus to perform irrigation and drainage operations by monitoring water and salt in a soil depth corresponding to crop roots, and removing excess salt from the crop roots, thus reducing the salt stress on crop growth, ensuring a crop yield, and reducing waste of water resources while realizing efficient utilization of existing water resources.
