Aerial photo taken on April 17, 2021 shows a plant-protection drone operating over a grape plantation at Hongyan Village, Xiaozhaiba Township, Xifeng County, Guiyang City of southwest China's Guizhou Province. Technicians from a local company of specialty agriculture services have been sent out to grape and kiwi fruit plantations throughout Xifeng County to direct farmers on their operation of plant-protection drones. These drones are more efficient tools for pest control, which would result in improved income for farmers. (Xinhua/Yang Wenbin)
