In the process of mechanization of agricultural production, one of the main problems in the research is that machinery cannot effectively adapt to various terrains. If the terrain is rugged and not suitable for mechanical work, or the machinery cannot stop normally during farmland work, it will seriously affect the mechanization of agricultural production. The spraying operation of small plant protection drones is mainly in the air, and the operation process will not be affected by the terrain. At the same time, small plant protection drones are small in size, and there is no need to build a special lifting platform during spraying operations. As long as a square open space of about 2.25 m2 is freed in the field, the small plant protection drones can effectively lift. Therefore, idle roads and open spaces in the field can be used as platforms for lifting small plant protection drones. If the terrain for planting rice is hilly, mountainous, etc., which is not suitable for drones to park, when pesticide spraying operations are to be carried out, a platform can be built manually to ensure that small plant protection drones can rise and fall in these uneven terrain. Normally implement pesticide spraying operations.
In recent years, the main requirements for preventing and controlling rice plant diseases and insect pests are: environmental protection, saving medicine and water, and the effective application of small plant protection drones in the process of preventing and controlling diseases and insect pests can meet these requirements. When spraying pesticides, control the spray volume of small plant protection drones to be between 300 and 1000 mL/mu according to the flight speed, the requirements of the target (that is, pests), and the characteristics of the pesticides used. Compared with conventional sprays, the characteristics of a small agriculture drone spraying are: the sprayed droplets are more evenly distributed and the atomization effect is better. When small plant protection drones carry out spraying operations, pesticides can be added with anti-floating additives, transpiration-inhibiting agents, penetrants and spreaders, etc., so that labor costs and farmers' inputs are reduced to a certain extent, which is effective Improve the economic benefits of rice production. In addition, when using small plant protection drones to carry out pesticide spraying operations, the airflow can also be used to evenly spray the pesticides on the surface of the rice leaves and stems to avoid long-term residual pesticides in the water layer and field soil. It can achieve better environmental protection effect.
When spraying pesticides to prevent and control rice pests and diseases, if the pesticide spraying operator and the medicament is too close, the medicament may be contaminated on the operator, seriously affecting the personal safety of the operator. When using small agricultural UAVs to spray pesticides, the spraying method adopted is remote control. Operators mainly use ground stations to receive satellite signals and remotely control small plant protection drones to effectively prevent direct contact between operators and chemicals, so as to effectively protect the personal safety of pesticide spraying operators.
