Unmanned aerial systems for biological plant protection based on UAV type CE-20

Abstract

The article presents an analysis of the use of UAVs of the CE-20 type as part of unmanned aerial systems for biological plant protection. The relevance of the study is determined by the intensive development of modern unmanned technologies used to combat insect pests and plant diseases. The proposed analysis of modern practice of using UAVs of the CE-20 type for biological plant protection will reveal the relationship of technical characteristics with agrotechnological methods. This will provide effective technical support for unmanned aerial systems applications in precision agriculture. It is important to consider that the characteristics of the UAVs used significantly influence the process of spraying fertilizers and pesticides. The article analyzes the previously obtained results of test flights of the CE- 20 of the Chinese company Wuxi Hanhe Aviation Technology. Testing was carried out taking into account a given field cultivation strip, on which the effective spray width of fertilizers and pesticides was determined and studied. The obtained droplet deposition coefficients of variation showed good deposition uniformity and penetration rate. It is shown that optimization of UAV parameters must be combined with agronomic requirements based on the choice of crop types, growth period, pest and disease characteristics, and environmental conditions.
