Bird-driving drones to guard the golden rapeseed fields, Jiangnan water town piece of rapeseed sea swaying with the wind, the golden waves of flowers shuttling between the light mechanical figure.These special devices equipped with the aircraft from time to time low hovering, sometimes hovering vigilance, with scientific and technological means to build up the protection of rape field air defense.This silent guarding action is writing a new story of modern agricultural development in China's vast farmland.
In this land where rape has been grown for thousands of years, farmers have accumulated a wealth of experience in repelling birds.Scarecrows, which can be seen everywhere in the fields, were once the faithful guardians of the farmers. Their faded cloth clothes flutter in the wind, confusing the birds with their still figures.Hanging ribbons and reflective films flicker in the sunlight, creating a visual deterrent with the interplay of light and shadow.There are even experienced farmers who, according to the pattern of the birds' activities, ring the gongs at certain hours to scare off the predators with their crisp sounds.
As the ecological environment improves and awareness of bird protection increases, the traditional methods of bird repelling face a double dilemma.The natural restoration of migratory routes has increased the number of birds in the fields, and the protected birds cannot be driven away by injurious measures.The lack of manpower to look after the fields due to young laborers going out to work has caused the cost of traditional methods such as hanging colorful flags and tying scarecrows to rise.How to balance ecological protection and agricultural production has become a new issue in front of contemporary farmers.
The core of intelligent bird repellent lies in the deep understanding of bird habits.When bird song is monitored, the system automatically plays the call of its natural enemy, creating a precise bio-acoustic repellent.
The multimodal deterrent system shows the humanistic temperature of science and technology.The ultrasonic module generates bird-sensitive acoustic frequency bands, forming an invisible barrier outside the range of human hearing; the bionic raptor model with variable-frequency flashing lights simulates the oppressive feeling of a sudden attack by a natural enemy; and the low-decibel directional acoustic emitters act like trained sheepdogs, guiding the birds away from the protected area.These technical means not only to maintain the deterrent effect, but also to minimize the physiological damage to birds.
The intelligent bird repellent system is deeply integrated with the farmland Internet of Things.Environmental sensors monitor changes in temperature, humidity and light in real time, and meteorological data are linked and analyzed with bird activity models to predict bird movements.Compared with traditional bird repellent methods, scientific and technological means avoid the use of chemicals and physical damage to protect biodiversity.After adopting the intelligent bird repellent system, the podding rate of rapeseed increased significantly, and the ecological landscape of dragonflies reappearing between the ridges of the fields demonstrated the possibility of a harmonious symbiosis between technology and nature.
Agricultural production methods are undergoing profound changes.Drone operators have replaced the janitors who patrol the fields and yell, and digital terminals have replaced ancestral farming calendars, but what remains unchanged is the deep watchfulness over the land.Looking to the future, the intelligent bird-driving UAS will develop in a more refined direction.The rape fields in the morning mist are flooded with golden ripples, and the bird-driving drone skims over the sea of flowers and casts a light trajectory.This is not a cold mechanical cruising, but the idyllic pastoral song played by science and technology and nature.When innovative technology is rooted in the land, what is guarded is not only the fruitfulness, but also the harmonious coexistence of the farming civilization that stretches for thousands of years and the modern ecological concept.In this field full of vitality, what we see is not only the quality and efficiency of agricultural production, but also the vivid practice of scientific and technological empowerment on the road of rural revitalization.
