it should be noted that, in order to improve the accuracy of allocation and allocation of water resources, the monitoring analysis performed from the sample water distribution aspect and the weather aspect is based on the data layer, and the actual abnormal state cannot be verified intuitively, so that the visual abnormal state of the crop needs to be further verified, and the corresponding scheduling and allocation of the water resources in the abnormal state need to be performed.
