Tourists are visiting the Agricultural Modernization Demonstration Zone of Yanjiagang Farm Co., Ltd. of Beidahuang Group. Reporter Zhang Tao photographed the agricultural monitoring system of Puyang Farm in Beidahuang. The modern rice production base established in the Northern Wilderness. Reporter Zhang Duan captured a vast expanse of fertile land, with birds chirping and insects chirping, and green waves surging. In Heilongjiang, the largest grain producing province in China, the summer management work of Beidahuang Group, which has the largest reclamation area in the country, is in full swing. The warm wind blows, and various crops are bathed in sunshine, rain, and dew, growing rapidly. From the Songhua River to the Xingkai Lake, and from the Black Water to the Ussuri, a change of promoting agriculture through science and technology is quietly taking place. A plant protection UAV is spraying liquid fertilizer into the paddy field pool over the plot of Yan Pengjia, a planter in Shuangfengshan management area of Beidahuang Group Baoquanling Co., Ltd. Yan Peng stood on the ground, looking at the drone's flight route with his phone, and smiled to the reporter, Using drones to fertilize and spray rice paddies and ponds is particularly uniform, allowing seedlings to absorb nutrients well and reducing fertilizer waste. Drones have a high efficiency in spraying liquid fertilizers, and by pre planning flight routes on a computer, drones can operate on their own, which is much easier compared to pure manual work. "" One drone operating for one hour is equivalent to five or six hours of work for a worker, "said Yan Peng, By using this drone to spray liquid fertilizer, the overall labor cost has decreased by about 40%. Zhang Lei, Deputy Secretary of the Party Branch of Shuangfengshan Management Zone, calculated with reporters that the entire management zone has a paddy field area of about 21000 acres, which can save about 40000 yuan in costs during the spraying of liquid fertilizer. Nowadays, most of the fertilizer spraying operations in the entire management area are using drones, and manual fertilizer spraying has become a thing of the past. Drone operation can not only improve operation efficiency, reduce labor costs, but also reduce pesticide usage, "adding green" to the black soil. Drone spraying pesticides can complete over 100 acres in an hour, "said Wu Bin, a planter in the birch management area of Beidahuang Group 290 Farm Co., Ltd., pointing to the drone passing overhead. In previous years, during summer management, Wu Bin would hire drones from other families when using pesticides. This year, he and several other planters jointly purchased a new type of plant protection drone, which increased the operating efficiency by about 20% compared to the original. Although purchasing drones increased expenses, pesticide costs were saved significantly. This type of drone is equipped with a brand new navigation system and algorithm software, greatly improving operation accuracy, planning operation paths more accurately, improving operation efficiency, and reducing the amount of medication by 10%. "Chu Changming, director of the Agricultural Technology Promotion Center of 290 Farm Co., Ltd., said that this not only reduces the cost of plant protection for farmers, but also reduces pesticide residues, making the planted grain more reassuring to eat. In recent years, Beidahuang Group has actively implemented the strategy of "storing grain in the ground and storing grain in technology", continuously introducing advanced agricultural modernization technology into various production links, continuously improving operational efficiency, and laying a solid foundation for ensuring national food security. Not long ago, at Sanhetun Airport in Jiamusi City, Heilongjiang Province, accompanied by the roar of engines, agricultural aircraft rushed into the blue sky and transferred to the established farmers in the reclamation area
