Guangxi is the province with the largest citrus planting area, its main planting is mandarin orange and sugar orange, mandarin orange planting is mainly concentrated around Nanning, Chongzuo as the southern Guangxi citrus planting area, its temperature is higher, the flowering period is earlier than Nanning. From south to north, the temperature and flowering period are different, and the flowering period is presented in order, from the flowering period to the full flowering period to the first flowering stage.
In the past, when the citrus flowers reach 50%, it needs to be shaken once according to the weather conditions, but usually because of the lack of manpower, fruit farmers will choose to spray and prevent gray mold when the flowers reach 70%-80%, if it encounters rainy weather, it is necessary to manually shake the flowers urgently, but because the manual shaking is time-consuming and labor-intensive, it may not be able to shake the flowers in time, which increases the management cost for the prevention of gray mold in the later stage.
The DJI T50 Agricultural Drone Fruit Tree Set has a 50kg load and 4 sprinkler heads, which can solve this problem for fruit farmers during the flowering period.
With the convenience of drones, fruit farmers will choose to shake the flowers 1 to 2 times during the flowering period, during which thrips and red spiders can be treated, and at the same time, they can also save pesticides and labor costs for the prevention and control of gray mold. Since citrus gray mold is one of the main causes of fruit peel after fruit enlargement, early flower shaking by drones can also improve the appearance and yield of fruits at the ripening stage.
Through the comparison of the effect of artificial flower shaking and drone flower shaking, the efficiency of drone flower shaking is not only much higher than that of manual flowering, but also the effect of flower shaking is equivalent to or better than that of artificial flowers, because of the large wind field of the drone, the petals stuck to the leaves can also be blown off, but it is difficult to shake off the petals stuck to the leaves by artificial shaking.
