First, use a multi-functional remote sensing drone to take remote sensing pictures of crops, and then extract the degree of occurrence of diseases and insect pests from the image information. After generating the prescription map, import the variable spraying system, carry out route planning and variable spraying, and finally, collect different sprays in the prescription map. The droplet test card arranged in the area of the rate is used to analyze the deposition density and coverage, so as to verify the reliability of the variable spraying system.
With the continuous development of China's aerial plant protection technology, my country's requirements for precision pesticide application are also getting higher and higher. The demonstration test data of the chufangagri agricultural UAV variable spraying system has laid a foundation for improving precision agricultural aerial plant protection pesticide application technology.
