Abstract: Agricultural Practice as a basic course in agronomy, it is a bridge between the teaching of crop theory, research and production practice, and plays a key role in the training process of agronomy students. In the context of the construction of New Agricultural Sciences, it is of practical significance to design and innovate the teaching reform of the Agricultural Practice from the perspective of online-offline blended teaching construction. The online-offline blended teaching mode of the Agricultural Practice was constructed on the basis of an in-depth integration of digital, information technology and teaching practice. This integration was implemented in three distinct aspects: the integration and construction of online course resources, the reform of offline teaching methods and content, and the optimization and upgrading of the course assessment and evaluation mechanism. It is recommended that the actual crop production and scientific research and innovation process be integrated into practice teaching. Furthermore, the organic integration of ‘production-learning-research’ should be realized, the transformation of the student-centred teaching philosophy promoted, and the quality of teaching improved.

Key words: online-offline, blended learning, Agricultural Practice, teaching reform
