In the grand strategic layout of rural revitalization, the low - altitude economy is emerging with its unique advantages and becoming a new engine for promoting the modernization of agriculture. Among them, drones, as a key carrier of the low - altitude economy, are being increasingly widely used in the agricultural field, injecting new vitality and transformative power into traditional agriculture.

Currently, it is the critical period for the field planting and management of Ligusticum chuanxiong. In recent days, Jiajiang County, Leshan City, has actively utilized drone equipment to carry out pest and disease prevention operations, precisely applying pesticides to repel pests, and fully ensuring the growth of Ligusticum chuanxiong in the middle and late stages.

Walking into the North - City Rice - Medicine Rotation Agricultural Theme Park in Jiajiang County, one can see drone operators adding fertilizers to the drones. Accompanied by the "buzzing" sound of the rotor blades, the drones take off with a "whoosh" and shuttle back and forth, spraying evenly according to the set route, altitude, and amount of fertilizer.

Mr. Chen, an operator who is operating the drone for fertilization, said, "Under good conditions, two or three people helping with the drones can complete the operation on 350 - 400 mu of land in a day, and the spraying is very even. Compared with the traditional manual spraying method, using drones for spraying is faster, has a lower cost, and is more efficient."

Passers - by watching the drone operation sighed, "The times have really advanced. In the past, when we sprayed pesticides and fertilized by hand, it was time - consuming and labor - intensive, and it was also easy to cause harm to the body. Now, with drones spraying pesticides, the contact with pesticides is reduced, and the pollution to the environment is also less."

The application scenarios of drones in agriculture are very extensive. They can be used not only in agricultural plant protection and fertilization but also in the transportation of bamboo and wood in mountainous areas and the transportation of agricultural products in the fields. With their advanced technical means, they can accurately perform various agricultural production tasks, greatly improving the efficiency of agricultural production and injecting new impetus into the development of agricultural modernization.

From "facing the loess" to "looking up at the starry sky". In recent years, Jiajiang County has actively explored new ways to combine agriculture with science and technology, using the power of science and technology to narrow the urban - rural development gap. In this "smart farmland" revolution, each soaring drone is writing a new footnote for food security and rural revitalization.
