In the end丨Technology empowers spring plowing What are the "new technologies" in the field?

"One day of spring ploughing and ten days of grain, ten days of spring ploughing of grain full of warehouses." Now is the busy time for spring plowing, but through the short video just now, I don't know if you have found that in today's fields, farmers are working less and less, the rumbling sound of agricultural machinery is increasing, and the motivation of various robots is getting stronger and stronger. New technologies such as Beidou satellites, unmanned aerial vehicles, and field weather stations have helped empower spring plowing, making the current fields full of "science and technology". According to the "2025th Five-Year Plan" National Agricultural Mechanization Development Plan issued by the Ministry of Agriculture and Rural Affairs, by 75, the comprehensive mechanization rate of crop cultivation and harvest in China will reach <>%. How to remotely "take the pulse" of crops? How can new farmers act as "handshakers"? What are the other "technological styles" in the field? Next, let's go to today's question.

New seeder transplanter Beidou navigation is "standard"

At present, a "robot war" is being staged in the farmlands across the country. Let's take a look at what new robots are now in the field?

Let's go to Xinjiang first to see - a seeder with Beidou navigation. At the 50,<>-mu spring wheat planting base in Liuhudi Township, Changjimanas County, Xinjiang, high-horsepower tractors equipped with Beidou navigation systems are sowing spring wheat with improved new seeders. This kind of seeder can be sown precisely according to the pre-set line, and the soil covering and drip irrigation belt are also completed simultaneously, which not only realizes the whole mechanization, but also improves the accuracy and efficiency of operation, and can sow about <> acres more than the traditional seeder every day.

Next, let's go to Jiangxi again. With the application of various intelligent new technologies, spring plowing production in Yongxin County, Jiangxi Province has rushed out of the "acceleration" and entered the early rice planting period in advance. Under the control of agricultural mechanics, rice transplanters move back and forth through the fields, inserting the first seedlings that have just grown neatly into the soil. Each rice transplanter is also equipped with the latest Beidou system, which can realize the whole process management of agricultural machinery operations at the remote end. The use of intelligence and mechanization can increase food production by 10%.

In this year's spring plowing production, the seedling breeding process has also been upgraded to a "new version". In the Huangnidong intelligent seedling breeding factory in Ji'an City, Jiangxi Province, green seedlings are neatly placed on the automatic seedling bed, and rows of automated circular seedling breeding equipment are running around the clock, with the operation of the machine, moving up and down at a uniform speed, so that the seedlings rotate to get better sunlight. The machine can also automatically spray water and fertilize, and with their help, one person can manage 6000,<> acres of seedlings.

Why can tea pickers be "handshakers"?

The use of agricultural technology has opened up a new space for farmers, and we will go to the tea picking plantation. Right now, it's the peak season for picking spring tea, and tea farmers everywhere are busy picking tea buds. But you know what? Now tea pickers can also be "shake-off cabinets". In order to help tea farmers increase production and income, the local cooperative university robot team, after continuous trial and improvement, has developed an intelligent tea picking robot that independently identifies tea buds and leaves. Follow the reporter's lens and go to the tea plantation in Hangzhou, Zhejiang Province to take a look.

Feng Xiaojie: I am now in the tea garden by the West Lake in Hangzhou, and now is before the Qingming Festival, it is a good time to pick spring tea, in this tea garden, in addition to the busy tea picking workers behind me, there is also a special "tea picking worker", which is the intelligent tea picking robot.

To identify young shoots in dense tea branches, tea pickers rely on rich experience, and this intelligent tea picking robot relies on artificial intelligence, through the recognition model equipped with deep convolutional neural network, it can continuously learn to store bud and leaf morphological characteristics to achieve automatic identification of tea plant shoots.

At present, this robot has been updated to the fifth generation, and the team has encountered many technical difficulties.

Professor Wu Chuanyu of Zhejiang Sci-Tech University: Then the biggest problem is that the color of our tea leaves and its background color are almost the same, and there is no obvious distinction. On the other hand, the target is very small, and our smallest picking point is only about 2 millimeters. In addition, this green space of our tea garden may be on the hillside, and there will be relatively less on the flat ground.

It is understood that the fourth generation of tea picking robot developed last year through the track, can be used in alpine areas, this year, the fifth generation of tea picking robot is mainly suitable for tea gardens in hilly gentle slope areas, using crawler mode to move back and forth, the above solar panel can be self-powered in sunny days, at the same time, there are two robotic arms, tea picking in two steps, one cut and one suction, there is a small scissors at the front end of the robotic arm, positioning the petiole of the bud leaf, after cutting the negative pressure straw at the end of the robotic arm will suck the bud leaf into the tea basket. The recognition accuracy rate has increased from 82% to 86% in the fourth generation, and the success rate of tea picking has also increased from 50% in the fourth generation to more than 60%.

Tea picker Zhang Xianqin: I have been picking tea for almost 278 years, and if we pick this young shoot, the fast person (picks) five or six catties a day, and the slow person (picks) more than two catties.

At present, the intelligent tea picking robot is still in the experimental stage, the fifth generation of robots to pick a bud leaf time is about 1.5 seconds, 1 hour can pick about 2400 bud leaves, and manual 1 hour can pick an average of 4000 bud leaves, in the number of manual temporarily ahead of the machine's picking efficiency. In the future, the team will continue to improve the tea picking robot, improve efficiency, etc., and achieve the goal of promoting the application of the tea picking robot.

How to achieve "one-stop" agricultural machinery services?

Agricultural machinery allows farmers to "free" their hands and act as "hands-on cabinets", and agricultural cooperatives have launched "one-stop services". In the past two days, in Xiangtan and Chenzhou and other places in Hunan Province, the local area is promoting an agricultural machinery service, from appointment, order, door-to-door to service, just make a phone call or tap the mobile phone screen, which is greatly convenient for farmers. Let's take a look at the site.

In Qingshanqiao Township, Xiangtan County, Hunan Province, rotary cultivators are carrying out the second round of rotary tillage in rice fields, and a week later, the first batch of early rice seedlings can be planted in the ground. Relying on the newly established Hunan Provincial Supply and Marketing Cooperatives Agricultural Socialization Service Alliance, grain farmers no longer need to buy their own agricultural machinery, and with just a phone call, agricultural machinery can be delivered to the field to provide agricultural machinery services for grain farmers.

Peng Chaoliang, a major grain grower in Qingshanqiao Town, Xiangtan County, Hunan Province: Through this big alliance of supply and marketing cooperatives, we can mobilize seven or eight machines to the edge of the field with only one phone call, which not only saves our farming costs, but also improves our grain cultivation efficiency.

In Kangping Village, Anren County, Chenzhou, grain farmer Xie Yinghui is making online appointments for ploughers and farm mechanics on his mobile phone to prepare for the upcoming ploughing work. This year, Xie Yinghui transferred another 200 acres of land to grow rice, and because his own equipment was not enough, he made an appointment for agricultural machinery and equipment online in advance.

Xie Yinghui, a grain farmer in Kangping Village, Pailou Township, Anren County, Chenzhou, Hunan Province: Now we place orders online, and when it comes to the operation, we are not afraid that we will not find the machine, and we will not delay my sowing season.

At present, the scope of agricultural machinery online appointment service has covered all townships in Anren County.
