An Effective Precision Afforestation System for UAV

Much agricultural and forestry land in the world cannot be accessed by ground planting equipment because of traffic, terrain, other factors. This not only causes low efficiency waste resources, but also has a negative impact on sustainable development forestry. Therefore, it is significant to develop an accurate, efficient, energy-saving aerial precision seeding system using unmanned vehicle (UAV) technology meet actual needs planting. In this study, UAV afforestation with GUI, UAV, positioning system, information interaction were developed related approaches such as electronic technology. The airborne device added control circuit chip launching speed cylinder seed loading speed, while flight jointly controlled accurately depth spacing. experimental results showed that maximum was 6.7 cm. At same smaller content sand gravel soil, higher sowing qualification index, greater depth. average absolute error dynamic route RTK-automatic position accuracy 7.6 cm, static hovering 7.7 Resulting from separate sown experiments three crops, pitch angle 75° gave highest germination rate. missing index qualified more than 95% at 120 r/min speed. studied paper good effect, can requirements afforestation, provides new technical means for managing forest plant resources.
