Pilots, take your place, 1, 2, 3... take off!" With an order from Tian Chong, the chief agronomist of the Municipal Bureau of Agriculture, 30 plant protection drones instantly lifted off the ground, and one drone was in the blue sky and white clouds. Hovering over the green wheat fields, strips of thin white mist are continuously sprinkled, intertwined into a three-dimensional colorful picture of modern agriculture. On April 10th, our city held a field meeting on the "Integrated Defense, Rule and Flying Defense" and "Green Prevention and Control" of high-quality wheat in the field of the high-quality wheat and high-yield demonstration zone in Xinqiao Town. Sophisticated plant protection drones and efficient operation scenes attracted waves of admiration and applause from the villagers present. "Look and see, it's flying..." "I didn't dare to think about the plane fighting drugs before. I heard that it can spray hundreds of acres of land a day...Looking at the drone in the sky, the villagers said With excitement and excitement. Accompanied by the buzzing sound of flying, a drone flies back and forth under the control of the pilot. The 8 propellers are spraying pesticides at a uniform speed and flexibly, completing the flight defense mission of 10 acres of farmland in just 10 minutes. . "Today's live meeting made me feel very shocked. With the rapid development of modern agriculture and the implementation of the rural revitalization strategy, I believe that unmanned aerial vehicles will control and rule flying defense operations will become the general trend of wheat field management in the future. Prevention can not only free the peasants from the heavy labor, but also reduce the health hazards of manual spraying. It also has the advantages of precise spraying, high efficiency and environmental protection, lightness and intelligence, simple operation, and time-saving and labor-saving. The next step is to Gradually expand the coverage of unmanned aerial vehicles in the city.†said Bi Jiangyuan, member of the Municipal Party Committee, Director of the Propaganda Department, and leader of the Municipal Agriculture Leading Group. "Usually under the operation of professional pilots, drones can fly against 350-400 acres of farmland every day, and the efficiency is more than 20 times that of labor. Compared with traditional manual spraying, pesticide spraying can save 30%. Compared with the previous introduction by the Municipal Agriculture Bureau Compared with the plant protection robot, it can reduce the crushing rate of wheat. During the flight of the drone, the air flow from the propeller can blow the wheat back and forth, spraying the liquid medicine on all parts of the crop evenly, and the effect is more Good." Tian Chong introduced. "Our company is an investment promotion project of the Municipal Agriculture Bureau. The introduced drone model is the new series of DJI MG1P. The price is 68,000 yuan per unit. The spraying effect is much better than that of manual labor. It can spray to the roots of wheat and is very smart. , The planned route will not have the phenomenon of heavy spray or leaking spray. Generally, after 5 days of training, a pilot can skillfully operate the plant protection drone.†The relevant person in charge of Hasen Agriculture Co., Ltd. told reporters, “At present, the plant protection drone It may be a little unfamiliar to most farmers, but I believe that drones are the future development direction of agriculture and the prospects are promising." Zhou Jiawen, head of the Huitong Farmers Planting Cooperative in Lizhai Town and a large grain grower, said: “I have contracted 500 acres of land and started using plant protection drones for flight control operations two years ago. It used to be more than 10 days to spray pesticides. Now It can be sprayed in more than one day. The price of integrated control of pests and diseases is about 13 yuan per acre, which is cheaper than labor. It can also reduce unnecessary damage to plants and damage caused by long-term contact with drugs. It is too convenient Up." Plant protection drones are so good, why are they not widely accepted by farmers? Tian Chong told reporters that in today's large-scale development of agricultural modernization, labor shortages and high costs, plant protection drones are the theoretically most efficient pesticide application machinery. . However, in the past, many technologies of plant protection drones were not mature. Our agricultural department has been groping and we have eliminated a batch of plant protection machinery while introducing them. The effect and efficiency of long-term spraying operations are the only way to test flight defense. After market testing, the current plant protection drone technology can basically meet the requirements of unified defense, rule, and flight defense of crops. Tian Chong said that in the promotion process, the plots of each family are relatively scattered, and they cannot be concatenated into square operations, which limits the efficiency of operations. He hopes that all towns and townships will cooperate vigorously to promote the advantages of plant protection drones and increase the awareness of farmers. We will jointly promote the prevention and control of diseases and insect pests by plant protection drones for flight control operations, and contribute to agricultural efficiency and farmers’ income. DWDM - Dense WaveLength Division Multiplex DWDM (Dense Wavelength Division Multiplexing) is the ability to combine a group of optical wavelengths with a single optical fiber for transmission. This is a laser technology used to increase bandwidth on existing fiber optic backbone networks. More precisely, this technology multiplexes the tight spectral spacing of a single fiber carrier in a specified optical fiber in order to take advantage of the achievable transmission performance (for example, to minimize dispersion or attenuation). In this way, under a given information transmission capacity, the total number of optical fibers required can be reduced.
