Cotton variable topping method and device, electronic equipment and storage medium

The invention provides a cotton variable topping method and device, electronic equipment and a storage medium, and relates to the technical field of agricultural monitoring. The method comprises the following steps: acquiring multi-stage satellite remote sensing data of a cotton planting area to be topped, wherein the multi-stage satellite remote sensing data comprises satellite remote sensing data in a cotton growth period; based on the multi-stage satellite remote sensing data, comprehensive growth vigor indexes of all sub-regions in the cotton planting region are determined, and the comprehensive growth vigor indexes are used for representing the comprehensive growth vigor level of cotton in the cotton growth stage; based on the comprehensive growth vigor index of each sub-region, determining the chemical topping pesticide application amount of each sub-region; and performing variable topping on the cotton planting area based on the chemical topping dosage of each sub-area. The accuracy of chemical topping
