In this paper,a tractor is used as a power machine.Firstly,the process of hanging ridging,compaction,mulching,drilling,sowing and sand covering is integrated.And then,the technologies of two sides rotary tillage ridging construction,barometric drilling+rotary perforation combined drilling,pressure metering,active sand removal and sand covering of limited switches is elaborated for the working principle of the prototype.Besides,key components of rotary tillage ridging,telescopic commutation power transmission and pressing film drilling are focused on designing.Finally,the multi process celery planting prototype is developed.Experiments for the prototype show that the width of the border is 118.3 cm,the average row spacing is 15.18 cm,the plant spacing is16.27 cm,the short diameter of the soil slot is 31.4 mm,the length is 44.9 mm,and the depth of the hole is 5.75～7.75 mm.All the above parameters meet the needs of celery cultivation.
