Drone planting trees began in Henan Province this year

Have you ever seen a tree planted in the sky? Have you ever seen a drone plant a tree? On the high mountains and mountains where manual work is difficult, the drone broke free from the constraints of the terrain and sowed the seeds with precision. A few years later, it will be a scene of "green mountains and white rivers".
In terms of aerial seeding afforestation, our province has adopted a construction operation mode combining helicopters and drones this year. The unmanned aerial vehicle used is the first aircraft in the country with advantages in seed capacity, and this technology is also in a leading position in China. On the basis of this year's pilot work, next year our province will promote the drone flying technology on a large scale.

Afforestation by drones on the banks of the Yellow River in Sanmenxia
At 9:20 a.m. on July 10, a drone slowly took off from the high platform by the Yellow River opposite the Swan Lake Scenic Spot in Sanmenxia, ​​humming and raising dust and blades of grass on the ground.
On both sides of the high platform, the mountains are undulating and the terrain is winding. Beneath the high platform, the Yellow River flows and the atmosphere is majestic. Above the high platform, the clouds are densely covered, and there is rain falling. Looking up and looking into the distance, the city of Sanmenxia on the opposite side is misty and misty, making it even more graceful.
This drone is not for shooting high-altitude footage. Its take-off marks that our province's leading UAV aerial sowing technology has officially entered Sanmenxia.
This drone is very large, with a length of more than 2 meters, a height of more than 60 centimeters, and a weight of 62 kilograms. The wing rotates and rises smoothly, and the green words "flying afforestation" on both sides of the fuselage gradually become blurred as the height rises. Inside the body, 60 catties of tree seeds are loaded, and under the operation of the drone, they will be sown on the mountains on the banks of the Yellow River.
This place is the end point for swimmers to cross the Yellow River. The greening of the mountains here, compared with the Sanmenxia urban area opposite, has long been incomparable, so it has also aroused the opinions of many citizens. To this end, the Sanmenxia Forestry Department decided to increase the green coverage rate here, so that the banks of the Yellow River here will be as green as time.
Luo Xuefeng, director of the Sanmenxia Forestry Bureau, said that due to the close proximity to the Yellow River beach, the slope of the mountains is relatively large, and artificial planting is also very difficult. They researched and decided to use the combination of drone flying and artificial afforestation to make these areas green as soon as possible. Next year, Sanmenxia will increase the area of ​​afforestation by aerial seeding, practice the concept of green water and green mountains as invaluable assets and green development, and make the mountains greener, the sky bluer and the water clearer.
Afforestation
This year, the pilot drone flying this technology is leading in China
The mountains are about to rain, the wind is blowing, and the sound of drones is also loud and quiet. Under the operation of the staff, the drone carrying 60 catties of seeds flew to a relative height of 30 meters and moved forward at a speed of 12 meters per second. This period is the time when there is more rain in our province, and soon the main flood season of "seven down and eight up" will come. The seeds sown in the air will absorb enough water to break through the soil and germinate.
From take-off to landing, it took only 4 minutes before and after the drone to spread 60 catties of seeds evenly on the hillside. In actual operation, the working area of ​​the drone can reach more than 4,000 acres in one working day, which is not only accurate, but also highly efficient.
Huo Baomin, head of the aerial broadcasting station of the Provincial Forestry Survey and Planning Institute, said that since June last year, our province has gradually started to explore drones for precise aerial seeding for afforestation. UAVs are more maneuverable and flexible, do not require fixed airports and runways, and do not have strict technical requirements for temporary take-off and landing sites. They can fly according to pre-designed trajectories, and aerial seeding and afforestation are more accurate. Cluster design.
This year, they plan to carry out 20,000 mu of drone aerial sowing operations in Huixian, Ruyang, Xichuan and other places. At present, the dual-rotor oil-powered UAV is in a leading position in China, with a seed load of about 100 catties, which is equivalent to several times that of ordinary small UAVs.
According to reports, at present, the only drone in China that is used for aerial seeding operations is this drone that is used for aerial seeding and afforestation in Sanmenxia.

Helicopter and UAV joint operations will promote UAV aerial broadcasting on a large scale next year
Dahe News? Dahe client reporter learned that in recent years, aerial seeding afforestation in our province has gradually shifted to low mountains and hilly areas with frequent human activities. This is an important ecological barrier in our province, and it is also the main battlefield for the acceleration of land greening, mainly concentrated in the Funiu and Taihang mountains.
Therefore, the aerial sowing mode in our province has been gradually trying to change from fixed-wing aircraft to helicopters and drones that are mainly flexible since 2015, opening up a new path for aerial sowing afforestation in our province. And this year's 310,000 mu of aerial seeding afforestation is a combination of helicopters and drones to carry out aerial seeding afforestation construction operations.
This drone is fuel-driven, which also frees it from the insufficiency and constraints of electric drive. This year, they will accurately calibrate different parameters such as seed load, speed, flight height, and seed flow rate, to provide technical support for the next large-scale promotion in the province.
Huo Baomin said that the use of new drone technology to carry out aerial seeding afforestation is a new way to implement the speed-up action of national land greening and speed up the construction of forests in Henan, greening the places that are suitable for greening, and gradually solving the remaining difficulties in the Funiu Mountains and Taihang Mountains in our province. The problem of afforestation in afforestation and the ecological restoration of mining areas that are in urgent need of re-greening, increase the vegetation coverage of the land, continue to expand the ecological space, and improve the ecological carrying capacity of our province.
According to Feng Weidong, president of the Provincial Forestry Survey and Planning Institute, the precise aerial sowing of unmanned aerial vehicles (UAVs) in difficult afforestation areas is a concrete manifestation of the Henan Provincial Forestry Bureau's implementation of the central ecological civilization construction concept, as well as the implementation of the provincial party committee and the provincial government's decision to build forests in Henan. The vivid practice of deployment is of great significance.
This year marks the 40th anniversary of aerial seeding afforestation in Henan Province. Over the past 40 years, aerial seeding has been implemented in 39 counties (cities, districts) in 12 provinces and municipalities with a total area of ​​more than 16 million mu, and the cumulative effect area is nearly 5 million mu. The early aerial seeding forests have been closed into forests, forming a large-area aerial seeding forest base, which has created huge economic, ecological and social benefits.
