Main applications of spray drone technology in modern

Using UAV technology can effectively monitor crop growth, pests and diseases, irrigation and so on. With the support of remote sensing technology, UAV technology can comprehensively understand farmland area, crop soil variation, crop types and crop periodic growth changes through aerial photography and images, so as to find out the activity signs of diseases and pests that are invisible to human eyes, timely understand crop growth problems, and take corresponding prevention and control measures in the first time. Uav technology not only covers a wide range of crop monitoring, accurate data, but also effectively saves operation time, these advantages are unmatched by traditional agricultural technology.

When it comes to crop dusting, because the drones fly in the air, the flight path can be set flexibly and the speed can be controlled by themselves. In addition, the UAV is light in weight, small in size and covers a large area of farmland, which can easily realize the pesticide spraying operation in the farmland area with complex terrain. And the liquid spray uniform, pesticide loss less, effectively avoid waste. At present, many pesticide spraying UAVs 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 exhaust gas and less pollution, which meets the requirements of the national development of green ecological agriculture and organic agriculture.

According to the Food and Agriculture Organization of the United Nations, more than 10 percent of the world’s food production has been reduced by pests and diseases, and poor control measures are the main cause of crop pests and diseases. The UAV technology is adopted to install infrared spectrum scanning facilities for the UAV. Through inspection, near-infrared light reflected by crops into the system can be found to form a multi-spectral image, so as to understand the activities of diseases and pests in a certain area of farmland, find out problems in crop growth in time, improve the prevention and control efficiency, and avoid grain reduction. Domestic studies show that the UAV equipped with multi-spectral sensors can successfully discover the information of grape leaf stripe disease, which provides an effective basis for understanding the situation of grape canopy diseases and pests.

The growth of crops cannot be separated from soil with a certain amount of moisture. The UAV technology is used to monitor soil moisture in farmland, mainly by carrying soil moisture detection equipment and obtaining image information related to soil moisture through visible light judgment. Based on the comparative analysis of soil moisture index, the soil moisture level is further deduced through modeling, analysis and calculation, which makes the data more accurate and real, so as to realize the efficient monitoring and management of farmland soil moisture. Based on the vast territory and complex terrain of China, using UAV technology to monitor farmland soil moisture can effectively reduce the monitoring costs. The mode of UAV carrying detection equipment is convenient to operate and flexible, and has high practical value.
