The invention discloses a seeding unmanned aerial vehicle. The seeding unmanned aerial vehicle comprises an unmanned aerial vehicle body, wherein a seed bin, a seed input device, a seed launching device, a vacuum pump and a gas tank are mounted on the unmanned aerial vehicle body; the gas tank is sequentially connected with an electromagnetic valve, a pressure stabilizer, an air-gas mixer, a gas fine adjustment valve and a gas inlet pipe. The air-gas mixer is connected with the vacuum pump, the air inlet pipe communicates with a combustion chamber, a high-pressure ignition head is arranged inthe combustion chamber, the outlet of the combustion chamber communicates with a launching pipe, the launching pipe communicates with the outlet of the seed bin, and a seed pushing device for pushingseeds in the seed bin into the launching pipe is arranged at the bottom of the seed bin. According to the seeding unmanned aerial vehicle, the sowing efficiency can be greatly improved. When a principle prototype is used for testing, the measured average transmitting frequency of the prototype can reach 0.7 per second, and when an optimization experiment is predicted to be carried out in the laterperiod, the transmitting frequency is predicted to reach the frequency of 3 times per second.
