For South Downs, complex terrain features of small plots of farmland, This paper attempts to use hollow UAV explore new ways to sow with the appropriate parameters.The UAV body structure with 8 rotors and 12 axis, each 2 rotors and 3 axis as a group support, composed of a typical 4-axis stabilized support structure.In the UAV body there is a self-gravity drainage ways inverted cone seed box, which volume is 3.7L, and has the size of 60 × 13mm rectangular discharge opening in its bottom.The discharge office directly spilled on a rotary blade plate which driven by a DC motor and then spread to broadcast the UAV body.The blade plate diameter of 350mm, a height of 120mm from the ground.In the fixed flight parameters, the sowing operation parameters of the airbone device (the discharge opening corresponding to sowing rate and blade revolution speed corresponding to sow) determines the evenness of the field rice.Use FUTABA T8FG transmitter and receiver system as remote control device used to transmit sowing parameters.The correspondence between the opening size of the area and LD knob channel scale is y=0.00069x2+0.11x+4.2(-66
