Method for diagnosing plant diseases and plant disease diagnosis system

A method for diagnosing plant diseases, comprising:

• acquiring plant images;
• determining identification information according to the plant images, which are acquired, wherein the identification information comprises at least one of species information and disease information;
• and
• extracting diagnostic information from a content management system according to the identification information, which are determined, and outputting the diagnostic information, the diagnostic information comprises a descriptive content of plants and their diseases, with regard to different plant images, if the identification information, which are determined, is all the same, at least part of the diagnostic information changes along with the different plant images, the at least part of the diagnostic information comprises reference images, the reference images at least correspond to the disease information, and the reference images are similar to the plant images;
• wherein the step of extracting the diagnostic information from the content management system according to the identification information, which are determined, and outputting the diagnostic information comprises:
• in the content management system, determining a candidate reference image library, which is corresponded, according to the disease information;
• in the candidate reference image library, determining one or more the reference images to be extracted and a priority corresponding to each of the one or more the reference images based on a similarity with the plant images and/or a consistency with the species information;
• and
• outputting one or more the reference images, so that one or more the reference images are arranged according to the priority in a descending order.
