Recently, several unmanned windrowers were operating in a rice field of Honghe Farm Co., Ltd. of Beidahuang Group. With the roaring sound, the unmanned windrower automatically moves forward, turns and reverses, and the operation is smooth and efficient. (The unmanned harvester of Honghe Farm Co., Ltd. of Beidahuang Group is in operation.) Zhao Huayu, a technician in the first management area of Honghe Farm Co., Ltd., shook his mobile phone and said that this unmanned windrower uses 5G and Beidou satellite navigation technology to design the walking route through the intelligent terminal system, so as to realize the unmanned operation of straight travel, head turning, cutting and header lifting. (The technicians of Honghe Farm Co., Ltd. of Beidahuang Group are using mobile phones to control the unmanned harvester.) In the unmanned smart farm of the agricultural science and technology service center of Beidahuang Group 858 Farm Co., Ltd., an unmanned harvester is harvesting in the paddy field with a "return" route under the guidance of Beidou satellite navigation. In a short time, the body warehouse was full, and the unmanned integrated tractor at the rear loaded and transported the newly harvested rice. The two vehicles cooperated with each other in a coherent manner. In Hongwei Farm Co., Ltd. of Beidahuang Group, Zhang Liangbao, a young "post-90s" farmer, has become an "old hand" in using unmanned agricultural machinery. In the harvest season, Zhang Liangbao stood at the edge of the ground, picked up his mobile phone and kept pressing, so the unmanned harvesters in the ground became busy. "Mobile phones are our 'new agricultural machinery'." Zhang Liangbao said. He continued to expand the use of unmanned agricultural machinery, from planting to harvesting, the whole process has been involved in unmanned agricultural machinery. Beidahuang Group is located in Heilongjiang Province, with a sown area of nearly 46 million mu this year. "Beidahuang Group is accelerating the deep integration of Internet technology and modern agricultural industry." Tang Hao, deputy general manager of Beidahuang Group, said that Beidahuang Group has successively built two batches of 20 digital farms, initially forming a replicable and promotable digital agriculture integrated application solution.
