Abstract

Abstract:

Under the background of “new agricultural science”, combing with the common problems existing in the teaching of phytochemical laboratory course in forestry colleges and according to the specialty characteristics of students, the improvement and practice are carried out from the aspects of teaching material construction, teaching content, teaching methods and laboratory construction. This can improve the teaching level and quality, further improve the comprehensive ability of students, and lay the foundation for the cultivation of application-oriented talents.

Key words: Phytochemical laboratory, Forestry universities and colleges, Teaching reform, Teaching practice
