The "Yancheng" UAV flew to Tian Tou to sprinkle pesticides.

With a roar, a drone rose from the field under the remote control of the operator, spewed milky water mist while flying, and quickly sprinkled the prepared medicine on a patch of green rice. This is the scene that Yancheng Evening News reporter saw at Yuema Village, Yanlong Street, Yandu District at about 4 pm yesterday.

"the drone carries a medicine box containing 10 liters of liquid medicine, which can be sprayed on more than 10 mu of land at one take-off and landing through three pressure sprinklers. The flow rate of the drug is preset. " Ren Zhaokun, a "flying hand" wearing a mask and operating drones, told reporters that drones are routinely spraying rice, flying at a speed and altitude that can be adjusted, usually spraying at an altitude of 3 to 5 meters above crops.

It is understood that the drone in flight is a genuine "Yancheng". "this is a'6-rotor pesticide spraying aircraft', an unmanned plant protection machine specially developed by our company for large-scale planting, which can spray 1 mu of crops in one minute." Lu Hongxiang, general manager of Digital Eagle Science and Technology Yancheng Co., Ltd., who directed the operation at the scene, told the Yancheng Evening News that this unmanned plant protection aircraft uses an advanced spray system, and the atomization effect of the sprinkler is several times that of the ordinary sprinkler, and the pesticide it sprays is almost invisible to the naked eye if it is not against the light.

This unmanned plant protection machine can work about 300 mu of land every day. "you see, the rice is now heading and it will be harvested in less than two months. how hard it will be for farmers to travel back and forth in the rice fields with sprayers on their backs." Lu Hongxiang pointed to the drones flying smoothly from a distance, saying that the use of drones can effectively solve the practical problems commonly existing in the process of crop plant protection, such as low efficiency and inconvenient operation, and the downward airflow generated by drones during flight. it can also enhance the penetration of the liquid and improve the effect of preventing and controlling plant diseases and insect pests.

"this year is the first plant protection test of drones in Yandu District, and we are also following and observing, and so far it seems that the results are really good." Qiu Xueping, director of plant protection in Yandu District, who is directing spraying operations at the scene, affirmed the spraying effect of drones, and he believes that drones will play a more and more important role in agricultural production in the future.

Shen Chun, a major grain grower, contracted a total of 1000 mu of farmland this year, and this time 40 mu of paddy fields were given to Digital Eagle Science and Technology Yancheng Co., Ltd. and the Yandu District Committee of Agriculture to conduct a "flight prevention" experiment, and the application of pesticides in the process of rice growth was handed over to plant protection drones. "Last year, manual medication was time-consuming and laborious, and the effect was not very good. People are also prone to heatstroke and poisoning in summer. Now that labor costs are getting higher and higher, with unmanned plant protection machines, you don't have to worry about not hiring people during the busy farming season! " Shen Chun said he plans to use drones on all 1000 mu of farmland next year.

It is understood that the market price of this model of YM-6160 drone is about 90, 000 yuan, which is indeed expensive for the average grain grower. "the drones produced by our company are not only sold to major grain growers in China and overseas markets such as South Korea, but also rent drones to cooperatives or farmers with small planting scale, who can entrust us to carry out integrated pest control. The whole 'flight defense' of 40 mu of rice for Shen Chun is a form of cooperation. " Lu Hongxiang said that since its establishment nearly a year ago, Digital Eagle Technology Yancheng Co., Ltd. has expanded the market through various forms, and only when users see real results will they recognize and buy drones.

In the company located in Yancheng National High-tech Zone, Yancheng Evening News reporter found that this rotary-wing drone is only one of their research and production models, and the company also has a number of fixed-wing drones in the shape of passenger aircraft. Lu Hongxiang said that in the impression of many people, drones are still "high-end". "however, with the popularization of intelligent technology in daily life, drones are not only used for plant protection, but also widely used in police security, remote sensing mapping, forest fire prevention, electric power patrol lines, search and rescue, film and television advertising, and other uses, the market prospect is very broad."
