The invention provides a crop identification method and related equipment. The crop identification method comprises the following steps: acquiring at least one image of a land parcel; determining phenological time and a phenological time interval corresponding to the at least one image by taking the sowing time of the to-be-monitored crop as a zero point of the phenological time; respectively extracting an image feature value corresponding to each pixel point on the at least one image; based on the image feature value corresponding to each pixel point, respectively determining an image feature change curve of the image feature value corresponding to each position point of the land parcel in the phenological time interval; generating a reference growth period curve of the to-be-monitored crops based on a plurality of images containing the to-be-monitored crops in a preset time period before the sowing time; acquiring a crop growth curve in a phenological time interval from the reference growth period curve of
