Taking Heilongjiang Bayi Agricultural University as an example, this paper analyzes the ways of the Great Northern Wilderness Spirit for cultivating application-oriented undergraduate talents in agricultural and forestry colleges, improving the curriculum system of undergraduate talents through innovation, strengthening the cultivation of students’ innovative ability, leading students’ scientific research and academic level, and enhancing students’ practical ability. To innovate the cultivation mode of application-oriented undergraduate talents in agricultural and forestry colleges under the guidance of the spirit of the Great Northern Wilderness, and to provide a reference mode for the cultivation of undergraduate talents in agricultural and forestry colleges in China.展开更多
