To improve the quality of field practice teaching in Botany, this paper proposed a teaching strategy integrating plant identification APP with pre-designed taxonomic keys by teachers. Based on the pre-designed taxonomic keys compiled by teachers in combination with the characteristics of plants in the practice area, this strategy covered representative groups such as pteridophytes, gymnosperms, and angiosperms, and clarified key diagnostic features as well as differences between easily confused species. During the practice, through the integrated model of “preliminary identification by APP + accurate verification by taxonomic key”, students were guided to cross-compare species characteristics. Meanwhile, practical activities such as self-made taxonomic keys, specimen preparation, and plant photography were supplemented to construct a multi-dimensional teaching system. The results of the pilot application in 2024 showed that the accuracy of students' plant identification was significantly improved, and their abilities in knowledge application and problem-solving were effectively transformed. The achievement degree of the course objectives of Biological Field Practice for the 2023 grade reached 0.84, an increase of 0.04 compared with the 2022 grade; the average score of field practice report (botany section) was 87.3 points, 4.46 points higher than that of the 2022 grade, indicating that the teaching effect of field practice was significantly optimized. This paper provided a reference for the teaching reform of similar courses.
