Abstract: Cultivating high-level composite applied professional postgraduates with master's degree is not only an inevitable need for building first-class universities and disciplines, but also a significant way to actively serve the implementation of rural revitalization strategies. As a backbone of the development of "agriculture, countryside and farmers", it is particularly important to explore the collaborative training mechanism for professional postgraduates in the context of "rural revitalization" in the new era. Based on the new requirements of higher education reform and the guidance spirit of the national agricultural professional postgraduates of education guidance committee for the master's degree related agriculture, this article explores the collaborative training mechanism of food related master's degree. On the basis of analyzing the differences and promotion channels of connotation construction in the current professional master's education, it is proposed to take "rural revitalization" as an opportunity currently, which is an important manifestation of the "sublimation" of food professional master's education. Meanwhile, combined with the approach of collaborative innovation training, a leapfrog "one-three-three" collaborative training system is proposed, and a collaborative training mechanism of "practice driven, multi-dimensional integration, and innovation leading" is further constructed with the "four modernizations" to serve as the main line. This collaborative training mechanism fully integrates educational resources in the new era which plays a vital role in leveraging the human resource value of food postgraduates, assisting rural revitalization, and achieving multidimensional development of education and society.
