Abstract: In order to study operating performance of vegetable cutting device for grafting and to practice producing seedlings, operating tests of 2JX-M series cutting devices for grafting were conducted to study grafting productivity and success ratio compared with manual work. Results indicated that, with above 90% success rate, 2JC-M cutting device for hole-insertion grafting and 2JP-M cutting device for cleft grafting could perform 1100 cucumber grafts per hour and 640 eggplant grafts per hour respectively, which were 1.64 times higher and 2.90 times higher than that of manual work. Compared with manual work, the cutting device for grafting improved grafting production rate and quality and decreased the effect of grafter’s proficiency, work fatigue and speed on success rate of grafting. This research provides a foundation for reasonable application of cutting devices.
