Abstract: This paper reviews the ways to promote interdisciplinary education for graduate students, including setting up specialized organizations or institutions, carrying out multi-field course teaching, strengthening the combination of production and study and the course extension of joint training of schools and enterprises. On the basis, this paper puts forward a new approach to the interdisciplinary education for graduate students of light industry technology and engineering. Interdisciplinary education through project course teaching is not only simple, efficient and low-cost, but also enables graduate students to better accept complete interdisciplinary science and technology knowledge within their limited learning time.
