“Field Day” no one goes to the field, unmanned agricultural machinery opens “a door” to smart agriculture

There is no one in the cab of the tractor. After the steering wheel turns by itself, a straight rotary tillage track is left on the farmland; no one is working in the green winter wheat field, and the remote control is flicked lightly, and the drone flies into the sky. , Complete 280 acres of plant protection work per hour. On April 13, in Cuicun Town, Changping District, Beijing, continuously variable speed tractors, agricultural machinery equipped with Beidou navigation system, and drones gathered in the field. This is the “Field Day” activity held by the Changping District Agricultural Mechanization Technology Promotion Station. A reporter from the Beijing News learned at the scene that some of the agricultural machinery operations displayed on the Field Day may not be the normal state of field operations in the suburbs of Beijing, but it is already the future that agricultural mechanized production can see.

Technological update, agricultural machinery operation further liberates labor force
Accompanied by the roar of the engine, the tractor on the field ridge started slowly, and the rotary tillage gear rotated round and round, leaving traces showing several straight lines in the field. Near the border of the field ridge, the machine quickly turned around and adjusted its direction. A new round of field work has begun. This time, the tractor driver did not sit in the cockpit. He stood far away and watched the whole process of the tractor.

“This is my country’s first large-scale continuously variable transmission tractor with 220 horsepower. It is still a prototype and can be transformed into electronic control, intelligence and wire control.” Zhao Xin, a doctoral student at the School of Information and Electrical Engineering, China Agricultural University, told Beijing News reporter, unlike automobiles, high-horsepower tractor CVT technology has always been a difficult point in the field of domestic agricultural machinery. “If CVT cannot be realized, it means that tractors still need manual shifting, which cannot truly liberate the labor force. It used to be an obstacle to our realization of unmanned driving.” Now, with the breakthrough of this technology and its combination with the Beidou navigation system, it means that tractors are entering a new era of unmanned driving.
On the other side of the cultivated land, the winter wheat that has turned green is almost knee-high, and the drone loaded with plant protection chemicals soars into the air, jumping about three meters into the air. With the remote control of the staff, the fine chemicals are evenly sprinkled like water mist, In ten or twenty seconds, the drone can complete the plant protection operation of an acre of wheat.

Of course, drones for plant protection are nothing new. In my country’s contiguous cultivated land and grain production areas, drones have become an inseparable helper for large planters and cooperatives. “The drone can not only carry chemicals, but also fertilize and sow seeds. One machine can be used for multiple purposes, and can complete 280 mu of field operations per hour. At the same time, compared with traditional plant protection methods, it can save 30% of pesticides.” Jifei According to Liu Danping, director of government affairs for science and technology, in fact, although drone flying is subject to certain policy restrictions in Beijing, it has been gradually popularized over the years, and companies will also provide training for buyers on flight reporting and maintenance.
