Chinese herbal medicine field collection training teaching has the limitations of growth season and growth environment, as well as the dangers of wild animals, poisonous snakes and poisonous bees. In view of the above problems, a teaching method of Chinese herbal medicine field collection simulation training was studied.Using the professional plant modeling software speed Tree to build the field virtual vegetation scene, tree plant and grass plant model can not only simplify the plant model, but also build the LOD plant model. Observe the fine plant model at a close distance and the simplified plant model at a long distance, we not only realized the creation of high realistic vegetation model, but also improved the real-time rendering efficiency of the whole vegetation scene. Combined with the advantage that 3dsmax has a large number of plant model libraries, we reduced the production of many Chinese herbal models. The field interactive training function and simulation scene construction used unity3d rendering engine. Based on the study of the actual process of field collection of Chinese herbal medicine, the system function module was designed, the system development method and process were proposed, the overall structure of the system was designed, and the field plants simulation training prototype system of Chinese herbal medicine was developed.The experiment shows that this training method enables students to be involved in the situation, arouses the enthusiasm of students' practical teaching, and helps them master the knowledge of Chinese herbal medicine.
