Uav flying prevention operation saves water and labor cost

Two people quickly loaded two plant protection drones into the car, straight to Zigong City Da ‘an District modern agriculture demonstration park drive. On the same day, they prepared to use the plant protection drone to control diseases and pests in the owner He Lanying’s 300 mu citrus garden.

When they arrived about 40 minutes later, He Lanying, standing at the edge of the citrus garden, saw them coming. “I finally wanted you here,” she said.

“Have you got all the liquid?” Yin asked the state.

“I’m ready.” He Lanying had arranged the liquid medicine bucket neatly.

Without taking a sip of water, they removed the drone from the car and quickly poured the liquid medicine into a bucket in the middle of the drone.

“Swish, swish,” under the remote control of Yin Xiangguo and Xie Minchang, the two drones took to the air and shuttled back and forth across the citrus groves, spraying liquid medicine, the whole process fast and efficient.

Although this citrus fruit, but many fruit surface has been sunburned, fruit a lot. He Lanying picked up a fruit in the field and said to the reporter, “Look, this fruit has been sunburned, this is commonly known as the ‘sun fruit’, become a waste fruit.”

In the past, encountered days of high temperature caused by the “sun fruit” increase, have to ask workers spraying, spraying, fertilization, complete pest control, supplement foliar water, foliar fertilizer and other tasks, enhance the drought resistance of fruit trees and crops.

But this year’s heat wave has made the job more difficult.

He Lanying gave the reporter calculate a account: the temperature is too high, on the one hand, it is difficult to invite workers for pest control, workers for a long time outdoor work exposure, easy to heat stroke; On the other hand, if five people work eight hours a day, a 300-acre orchard will take about seven days, and some will fall fruit before they are “cared for”.

Under the guidance of the Agriculture and Rural Bureau of Da ‘an District, the local promotion of UAV flight prevention operations can greatly reduce labor costs, shorten the operation time, and avoid workers from being exposed to the sun for a long time.

“Two UAVs can be used for flying prevention operations in just two days, saving 20 percent of medicine and 80 percent of water compared with manual operations.” “The drones will fly at an equal speed and spray every fruit tree without missing a single tree,” Yin told reporters.

Facing the continuous high temperature fine hot weather, for days, organize agricultural extension personnel into the fields of zigong, vigorously promote new machines and new technology, intensify agricultural machinery technical guidance services, drought-resistant cover production, completes the monitoring in the field of food crops to maturity, organize farmers of mature rice, maize, sorghum and other crops in a timely manner to carry out the harvest, To ensure that spring grain mature a piece, a piece of harvest, grain warehousing, timely clean up corn, sorghum straw, for soybeans, sweet potato and other crops to make space, to ensure the normal growth of crops and yield formation. Appropriate use of straw shade, prevent water evaporation, strengthen the irrigation station maintenance management, multiple measures to pump water, water delivery, to ensure normal production.

In drought-prone areas and areas without adequate water resources, we will appropriately promote drought-tolerant crops such as sweet potatoes and beans, expand the planting area of drought-tolerant crops with strong stress resistance, and increase the supply of seeds, seedlings, fertilizers and pesticides to ensure that they are adequately replenished and properly deployed.
