In actual operation, the ideal flying height of the multi-rotor plant protection drone is 70-80m, and each seed is 150-180kg, and the cost is about 7500 yuan / hour. Because the flying height is too large, a large number of missed broadcasts will be generated, so in actual operation, continuous supplementary broadcasts are required. At the same time, in actual operations, due to the high requirements for the stability of the airflow, the operation can only be carried out when the airflow is gentle during the two periods of 5: 00 ~ 9: 00 am and 5: 00 ~ 7: 00 pm.
At the same time, the existing drone planting afforestation, there is a large amount of wood seeds. Taking Shenmu County as an example, the average amount of seeds used for aerial seeding is 6kg / hm2, and the seedling rate of forest trees is only 10%. The number of seeds used for afforestation by airplane is five times as much as that used for artificial seedlings. Secondly, the local geographic conditions are fully utilized. Airplane seeding can only achieve a wide range of tree species characteristics and natural conditions. It is impossible to select afforestation tree species according to local conditions according to local slope, soil moisture, and vegetation.
With the development of multi-rotor crop spray drone, various manufacturers are also actively expanding into new industries, and drone planting seeds has also begun to enter the horizons of various manufacturers. In view of the shortcomings of the current drone sowing, the flexibility and maneuverability of the multi-rotor plant protection UAV has been fully reflected.
