The main application of drone technology in modern agriculture

The use of drone technology can effectively monitor the growth of crops, pests and diseases, irrigation, etc. With the support of remote sensing technology, UAV technology can comprehensively understand farmland area, crop soil variation, crop type and crop cyclical growth changes through aerial photography and images, so as to discover signs of pest and disease activities that are invisible to the human eye, and timely understand crop growth problems. Take appropriate preventive measures as soon as possible. UAV technology not only involves a wide range of crop monitoring and accurate data, but also effectively saves operation time. These advantages are unmatched by traditional agricultural technologies.

In terms of pesticide spraying on crops, because the futurefarming drone flies in the air, the route setting is flexible, and the flight speed can also be controlled by itself. In addition, the drone is light in weight, small in size, and covers a large area of ​​farmland, which can easily achieve pesticide spraying in farmland areas with complex terrain. Moreover, the liquid medicine is sprayed evenly, the loss of pesticides is small, and waste is effectively avoided. At present, many pesticide spraying drones with exquisite design and low vibration not only spray accurately, but also have stable downdraft and high controllability. The spraying process is rarely affected by bad weather, and the spraying process has no waste gas and less pollution, which meets the requirements of the country to develop green ecological agriculture and organic agriculture.

According to the data provided by the Food and Agriculture Organization of the United Nations, the global food production due to pests and diseases has decreased by more than 10%, and poor control measures are the main cause of crop pests and diseases. UAV technology is used to install infrared spectrum scanning facilities for UAVs. Through inspections, the near-infrared light reflected by crops into the system can be found to form multi-spectral images, so as to understand the activities of diseases and insect pests in a certain area of ​​farmland, and timely detect the crop growth. Identify problems, improve prevention and control efficiency, and avoid food production reduction. Domestic research has shown that modern agriculture drone equipped with multispectral sensors can successfully detect information on grape leaf stripe disease, providing an effective basis for understanding the disease and insect pest status of grape canopy.

The growth of crops is inseparable from the soil with a certain amount of moisture. UAV technology is used to monitor the soil moisture of farmland, mainly by carrying soil moisture detection equipment, and obtaining image information related to soil moisture through the method of visible light judgment. Based on the comparative analysis of soil moisture indicators, the soil moisture level is further deduced through modeling, analysis and calculation, so that the data is more accurate and real, so as to achieve efficient monitoring and management of farmland soil moisture. Based on the current situation of my country's vast territory and complex terrain, the use of drone technology to monitor farmland soil moisture can effectively reduce monitoring costs.
