"What I dreamed of five years ago has finally come true today. Drones are really a good helper." During the spring ploughing season, liu rui, director general of jingsong agricultural machinery service cooperative in Suzhou city, anhui province, was in a good mood. On the one hand, he enjoyed the growth of wheat, on the other hand, his work efficiency was greatly improved.
His "good helper" is a DJI T20 agricultural plant protection drone he just purchased. The drone has come in handy this year for wheat disease control and fishpond spraying.
"We are spraying the medicine to prevent wheat scab these days. It is not a problem to spray 600-800 mu a day. This couldn't have happened in the past three or five days." Liu rui told reporters.
Anhui is a major agricultural province, with a total grain output of more than 40.5 billion kilograms last year and about 43 million mu of wheat in the field. In recent years, large agricultural households and cooperatives have adopted "dark technologies" such as uas and robots for pesticide spraying. The upgrading of agricultural production technologies and equipment has provided a prerequisite for the transformation and development of agriculture. How is the actual application effect of agricultural high-tech, what kind of policy support is needed for technology promotion, and how does talent training meet the actual demand? With these questions in mind, recently, the reporter of China youth daily · China youth net went to the main grain producing areas of anhui province to conduct an in-depth investigation.
Pesticide spraying is an important part in the process of crop planting. In the early years, the electric spray machine was used to spray the medicine manually, and later the machine was used to spray the medicine with a spray rod, but "people walking in the field are easy to step on the wheat, the machine is easy to press the wheat, people also have the risk of poisoning," they were worried about this.
Since 2015, Liu rui tried to use drones to sow seeds, but the drone flight control system was not perfect at that time, requiring high professional level of operators. Now, the drone can automatically navigate, sowing path deviation within 2.5 cm, reducing replay, missed sowing, work efficiency is greatly improved.
"After setting the flight path, the error of the machine will be within 0.5 meters, and the machine will fly for 20 minutes at a time. It can be used to spray pesticide to ensure the uniform dosage at different speeds." Liu said the use of drones can save pesticides, just in line with the country's requirements to reduce pesticide use.
"As far as I know, there are about 200 drones used by agricultural cooperatives in Suzhou. As the control system becomes more high-precision and intelligent, drone technology will have wider application space." He added.
At the same time, in the Anhui Fuyang city and Huainan city wheat control rule operation site, anhui qiyao aviation technology co., LTD.
Company director wang Yadi to calculate a reporter account: compared with artificial spraying, each plant protection drone work efficiency equivalent to 60 labor force, and can save 30% of pesticides and 90% of water resources, but also has convenient and efficient, environmental conditions wide adaptability and other advantages.
It is understood that since 2004, China began to research and promote uavs for industrial exploration. In recent years, with the upgrading of uav equipment function, technology and system, plant protection uav is gradually popularized. According to data, China's industrial drone application scenarios are relatively diverse and broad, but the most widely used field is agricultural plant protection, accounting for 42%.
