Smart agriculture shows its talents——
Science and technology "grab the spring" live up to the farming season
【Smart Spring Plowing】

"At the end of the beginning of spring, plan for planting early." At present, preparations for spring plowing have been carried out all over the country.
Looking at the fertile fields in the countryside, smart agriculture is showing its talents - modern agricultural machinery "plays the leading role", agricultural technology experts go to the fields to provide technical guidance, and there are busy scenes of technology "grabbing the spring" everywhere.
Smart agricultural machinery makes spring plowing run faster
In the sky, drones are flying to carry out precision spraying; on the ground, multi-wheeled wheat compactors and truss sprinklers shuttle back and forth... With the help of smart agricultural machinery, spring plowing in various places has accelerated.
On February 8, at the demonstration base for returning to farming in Renmei Town, Danling County, Sichuan Province, 1,600 mu of rapeseed seedlings had entered the bolting stage, and urgently needed treatment to strengthen stalks and prevent and control aphids.
"The drone we use has a drug load of 100 liters, and it can spray 20 acres of rapeseed at a time when flying out." Li Kexue, head of the Danling County Scientific Grain and Oil Professional Cooperative, who is busy in the base, and the drone operator Final communication preparations are underway.
Then, a large UAV rose from the ground and flew at a low altitude at a constant speed. The sprayed pesticides were in the form of mist and evenly sprinkled on the rapeseed seedlings.
In less than 20 minutes, the drone completed the spraying of 20 acres of rapeseed.
"Using drones to disinfect rice diseases and insect pests on a large scale is not only effective, but also saves time, effort and money." Li Kexue calculated a detailed account for the reporter of Science and Technology Daily.
Taking the existing 1,600 mu of rapeseed in the base as an example, in the way of manual spraying, personnel must be arranged in advance according to the weather conditions. Each person can only spray 5 mu of spraying at most per day, and the average salary per mu is 24 yuan. It takes about a week for 50 people. time; while using drones to spray medicine, you only need to set the flight speed and operation trajectory in advance, and the drones will carry out operations according to the set procedures. The average cost per mu is 8 yuan. Spray in place.
On the same day, in the wheat field of Xizhai Village, Tianzhuang Town, Pingdu City, Qingdao, a wheat crushing machine was crushing the wheat field.
"Last year, we purchased a new multi-wheeled wheat suppression machine, which is fast and efficient. In previous years, it took about ten days to suppress wheat, but this year it only took five days to complete it." said Hou Songshan, head of Qingdao Xizhai Agricultural Machinery Professional Cooperative, " Mechanical suppression can resist drought and protect seedlings, and can also promote weak growth and control vigorous growth."
Not far away, a sprinkler device caught the reporter's attention.
Liu Minggang, a farmer in Xizhai Village, is watering the wheat in the field.
"As the temperature rises, the amount of water evaporates. Irrigation in spring is conducive to the turning green and growth of wheat." Liu Minggang pointed to the sprinkler and said, "After the wheat turned green this year, the surrounding farmers have used the reel sprinkler irrigation machine, 24 hours a day. Working hours, the spraying effect is good, it saves water and is uniform, and can save 10% of water per mu.”
The support of science and technology makes spring plowing and preparation strong
Technology is the key to increasing agricultural production and income.
From north to south, agricultural technology experts go to the front line to check the condition of seedlings, pests and diseases, and crop growth, provide technical guidance, and use technology to support spring plowing and preparation.
A few days ago, Shanxi Province held a video conference on spring field management and spring plowing preparation work in the whole province, requiring all departments in the province to plan early and carefully organize, do a good job in spring field management and spring plowing preparation work without missing the farming time, and resolutely lay a good foundation for this year's agricultural production. One battle".
During spring plowing and spring sowing, the Shanxi Provincial Department of Agriculture and Rural Affairs will organize relevant technical units to issue guidance on the production of grain, oilseeds and other crops, set up an expert guidance group for the production of wheat, corn and other crops, carry out the "Technology Helps Harvest Experts Grassroots Tour" activity, organize agricultural technology Extension personnel went to the front line to guide farming and implement technical measures to increase production and income.
"Farming time does not wait for anyone, fertilizer and water can keep up, prevent diseases and insect pests, and ensure a good harvest." On February 8, Chen Bingqiang, senior agronomist of Qingdao Agricultural Technology Center, came to the wheat field in Xizhai Village, Tianzhuang Town, Pingdu City, Qingdao , to impart technology to the folks.
According to Chen Bingqiang, there are currently 3.487 million mu of winter wheat in the field in Qingdao, an increase of 60,000 mu over last year. The wheat seedlings are growing well, and the first and second types of seedlings account for more than 87%, which has set up a "harvest shelf" for summer grain production.
