The development of modern agriculture requires the self-development and construction of the undergraduate practice course of plant production.How to organically integrate the traditional teaching contents with the teaching demands of keeping pace with the times through the optimization of teaching methods is an urgent problem to be solved.This paper summarized the characteristics of the undergraduate practical course"Plant Field Technology"of China Agricultural University as an example.We investigated the teaching status for two consecutive years in 2019 and 2020,analyzed the advantages and places for improvement in teaching,and finally discussed how to optimize the teaching methods from six aspects,such as theoretical and practical teaching ratios,online and offline integration,use of multimedia library,digital crop specimens,construction of new teaching materials,and second classroom.This information is important for the construction of the undergraduate practical course of plant production.
