in addition to aerial photography, in which field is there a rigid demand for UAVs? The answer is agriculture, especially in the field of plant protection in agriculture. Recently, a drone company launched a drone capable of carrying 30 kg of fuel. According to reports, the current agricultural UAV market space has exceeded 50billion yuan. Some agricultural experts said that in the Chinese market, which needs intensive cultivation, distortion free drones are in good use

the spraying efficiency is four times that of tractors

at present, the field of agricultural plant protection UAVs in China has developed rapidly, including 8-rotor, 6-rotor, 4-rotor UAVs, and helicopters, which are all being developed by companies

on December 8, the "Changfeng 30kg oil powered multi rotor plant protection UAV tianma-1" launched by Changfeng UAV company was unveiled in Shenzhen. This UAV is full of "black technology": the oil drug load is 30kg, and the endurance time at full load is up to 1 hour. It can independently plan the spraying path, take-off and landing with one button, and spray independently. Its flight trajectory and spraying accuracy are accurate, and its efficiency is 4 times that of the tractor

according to Zhao Zichao, CEO of Changfeng UAV, the load of traditional UAV is less than 15kg, and it needs frequent charging. The new fuel direct drive plant protection UAV has a load of at least 25kg (excluding oil) and a flight time of 1 ~ 3 hours. According to Zhao Zichao's estimation, the efficiency of electric multi rotor plant protection UAV is 300 ~ 600 mu per day on average, that of tractor is 300 ~ 500 mu per day, and that of Chang Feng's oil multi rotor plant protection UAV is 1000 ~ 2000 mu per day

traditional paddy field operation is expected to be fully mechanized

"carry a spray machine and walk in the field." Xue Xinyu, director of the plant protection and environmental engineering technology center of the Nanjing Institute of agricultural mechanization of the Ministry of agriculture and chief scientist of the plant protection machinery research team of the Chinese Academy of Agricultural Sciences, is an expert with 30 years of research experience. She told that the most difficult part of traditional paddy field operations is the application of pesticides. At present, mechanization can be achieved in both farming and harvesting in China, but the only link of plant protection (plant protection) still depends on labor

with the explosive development of unmanned aerial vehicles in the past three to five years, unmanned aerial vehicles have not only undertaken this equipment in aerial photography and other fields, but also achieved great development in the field of plant protection. "Drones have begun to really undertake agricultural operations." Xue Xinyu said that the operation efficiency of plant protection UAV is more than 50 times that of manpower, and the cost is lower. Moreover, the plant protection UAV does not directly contact crops during plant protection, which will not reduce production

according to Xue Xinyu, the characteristics of UAV include high operation efficiency, convenient transfer, and suitable for operation in places with mixed human settlements. Remote sensing acquisition of low altitude agricultural information, agricultural aerial plant protection, and assisted pollination are the three main applications in the field of unmanned aerial vehicles. These operations are the difficulties of traditional operations, and their efficiency is particularly low. Now, they can be solved at one go through unmanned aerial vehicles

the annual scale of the UAV plant protection market can reach 50billion

it is understood that both China and the United States, the industry has realized the huge prospects of UAVs in the agricultural field. According to Xue Xinyu, according to the prediction released by the UAV Association of the United States, agricultural UAVs will account for 60% of the entire UAV market by 2020, with the resolution r of meize being 1.5% of the variation range and 1 increment. In Japan, agricultural aviation operations account for 54% of the total cultivated land, and drone operations account for 38% of aviation operations

Xue Xinyu said that among the ten breakthrough technologies reviewed by MIT in 2014, agricultural UAVs ranked first, ahead of brain atlas chips. MIT magazine commented at that time: "agricultural UAV is a change to the traditional mode of production, and will play a greater role in the future."

in mainland China, Xue Xinyu said that as early as 2008, the country set up the first 863 project to carry out unmanned aerial vehicles to operate on paddy fields. In 2014, the No. 1 document of the Central Committee put "accelerating the construction of agricultural aviation" in the column of scientific and technological innovation. However, Xue Xinyu said that agricultural aviation operations in China account for less than 2% of the total cultivated land, which is still far from the world average

Zhao Zichao, CEO of Changfeng UAV, said that under the background of land circulation and the gradual reduction of rural labor population, using UAVs for plant protection operations is very meaningful for rural areas, agriculture and farmers. "China has an area of 1.8 billion mu of cultivated land. If the rate of UAV plant protection operation reaches more than 50% in the future, the area of cultivated land using UAV plant protection operation will at least reach 1billion mu." according to the plant protection cost of 50 yuan per mu per year, the scale of UAV plant protection market in the future will reach at least 50billion yuan per year. "

why do UAVs shine in the agricultural field

agricultural technology is more mature

according to Zhao Zichao, CEO of Changfeng UAV, unlike aerial drones driven by batteries, agricultural UAVs are driven by fuel

"for electric UAVs, load and endurance are insurmountable pain points." Zhao Zichao said that after long-term research, it was found that in order to fundamentally solve the problem of load and endurance, we must use fuel power and replace the motor with an engine. Therefore, their team decided to develop the oil powered multi rotor UAV from the beginning, and finally decided to adopt the oil powered direct drive scheme

looser policy control

Zhao Zichao said that UAV, as a new thing, will face many doubts in various fields of production and life, especially safety issues. If the safety problem cannot be solved, the national policy will not be implemented. It was initially used by the automotive industry to determine the anti vibration characteristics. Although many applications of unmanned aerial vehicles face many policy risks, the safety risk of using unmanned aerial vehicles in agriculture is very small because the use environment is basically farmland, the population density is low, and the flight is not high. Therefore, the policy risk of UAV agricultural application is small

artificial intelligence promotes the agricultural revolution

UAV is essentially a "winged robot", which is a part of artificial intelligence and robot industry. With the wide application of artificial intelligence in agriculture, farmers will gradually leave the land and become land operators from land workers

in the future, robots will become real labor and assets. In the future, 10 billion human beings and 1 trillion robots will coexist. In agriculture, all cultivation and management will be done by machines

as laimingzhen, chairman of No.1 capital, said, there will be more and more farmers in the future, not in the traditional sense. Artificial intelligence will liberate farmers from the land and give them more opportunities to go to the outside world
