More crop farmers turning to drone use

URUMQI - An increasing number of drone operators are helping farmers across China harvest their crops, reducing the costs of pesticides and increasing yields.

One drone operator, Ma Yangyang, brought more than 30 drones from eastern China's Anhui province to spray defoliant on cotton fields in the Xinjiang Uygur autonomous region this autumn.

Ma purchased an unmanned aerial vehicle for agricultural plant protection and joined a UAV squad last year. The 25-year-old learned to operate the drone skillfully, and soon became a team leader.

Over the past year, he has traveled to the eastern province of Jiangsu, the northeastern province of Heilongjiang and the Inner Mongolia autonomous region in the north, using drones to spray agrochemicals for different crops, including wheat, corn, soybeans, sorghum, sesame, cotton and even forests. "Everywhere the team arrived, we were warmly welcomed," he said.

Ma and his team spent more than a month in Xinjiang, the most important cotton-producing region in China, with over 2.5 million hectares of cotton fields.

October is when the cotton is harvested. Defoliant must be used in advance to remove the leaves before the cotton is picked.

Zhang Lin, a major cotton farmer in Xinjiang's Yuli county, was skeptical about the small flying machine when several representatives from XAG, a leading agricultural high-tech company with its headquarters in Guangzhou, Guangdong province, introduced the drones to him in 2016.

"They said the drones can spray defoliant, consuming much less water than tractors do. They also promised that there would be no fee if I was not satisfied with the results, and the crops would not be damaged. So I decided to have a go," Zhang said.

An operator positioned himself on the edge of the farm, Zhang said. Manipulating the controls with his fingertips, the drones took off, sprayed chemicals along the route and returned automatically.

"It's amazing," Zhang said. "It costs less than renting tractors. Drones use less water and chemicals. Tractors used to damage around 8 percent of the cotton and also harmed the soil. Now, drones can solve all those problems."

Since new technologies have won the acceptance of cotton farmers in Xinjiang in recent years, more drone operators have come to the region to offer their services.

Statistics from XAG show that more than 4,500 of the company's drones helped local farmers defoliate 866,666 hectares of cotton this year.

The regional agricultural administration said that by the end of this year, the number of UAVs for farm use operating in Xinjiang is expected to exceed 5,000.
