Development Status Quo and Trends of Low-altitude Unmanned Aerial Vehicles Spraying Technology

Pests and diseases is one of the important factors of restricting sustainable development of agriculture.In the case of lack of effective early warning means and physical control means，chemical control is still one of the most important means of prevention.Low-altitude UAV spraying as a novel means of pest control，which has its unique advantages compared to traditional manned aircraft and ground spraying pesticide.This technology is becoming the new highlights and hotspots in the field of agricultural machinery.Advantages of low-altitude UAV spraying technology were introduced.Type and application status of equipment of low-altitude UAV spraying technology at home and abroad were compared.Current problems of low-altitude UAV spraying technology in china were analyzed.Trends of this technology in China were expounded.Application of low-altitude UAV spraying equipment will increase efficiency of pests control and promote sustainable development of agriculture in China.
