Abstract: Specimens are important teaching resources for experimental teaching of plant diseases and insect pests, in which slide specimens play an important role. Due to the limitations of traditional slides in teaching, the rational use of digital specimens is an efficient way to improve the quality of experimental teaching. The real slide specimens are transformed into digital slide teaching resources by an automatic micro-scanning system and they are stored on a cloud server. Teachers and students can access the database and browse the specimen resources through an online website. As a result of the digital slide specimen resource sharing platform, the teaching resources of plant diseases and insects are further optimized and the quality of teaching is improved.
