CCTV News: With the in-depth application of the Beidou satellite navigation system, the harvest of grain on the mainland has begun to be closely related to "looking up at the starry sky". Next, we will follow the reporter of the main station to visit the field, how Beidou technology helps science and technology to grow food.
Upgrade UAV "Iron Bull" automatic obstacle avoidance busy debugging
At present, the autumn grain harvest across the country is in full swing, and there is also a group of young people in the Beidou Building, who are undergoing a special autumn harvest. Why is it special? There is no one on this tractor, this is Beidou's unmanned technology is being debugged on site.
The yellow "Iron Bull" seen now is a Beidou unmanned agricultural machinery that can automatically avoid obstacles, the so-called automatic obstacle avoidance is that the unmanned agricultural machinery can automatically avoid obstacles, avoid unnecessary risks, and ensure the safety of field work. The reporter noticed that this time it was a real person participating in the obstacle avoidance test, is this safe?
Xu Ding, a field tester of Wuhan Exsun Beidou, said that the safety of this drone is still high. From last year to this year, 8 hours of uninterrupted testing in different farmland environments will make its safety more accurate and reliable.
The "small food truck" is more accurate in feeding and feeding
Reporter: "Add vegetables, add vegetables, let's see, this car is not like a common small food car, but it is for the Beidou agricultural drone to "feed", but the "material" it adds is not ordinary. ”
Xu Ding: "This set of equipment uses the perception terminal of Beidou, which is equivalent to installing "eyes" and "ears" on Beidou unmanned agricultural vehicles. The use of inertial navigation, laser, vision and other technologies, similar to the installation of a small WiFi near the farmland to receive signals, within the controllable range is more accurate. ”
Reporter: "Why do you pick so finely?" ”
Xu Ding: "Food security is cut out of every inch of land and every grain of grain. ”
"One map" dispatching agricultural machinery services are fully covered
Let's unveil the support of the "smart brain" behind the unmanned agricultural machinery, and let's see that the reason why they can operate efficiently and intelligently depends on the Beidou agricultural service management cockpit in front of them. Through this system, Hubei agricultural machinery "one network" can realize emergency dispatch. For example, if a certain place encounters continuous rainfall during the critical period of autumn harvest, you can look at the area where agricultural machinery is concentrated according to this map, and schedule it in time to avoid the situation that there is no agricultural machinery available for autumn harvest and autumn planting, and ensure the smooth development of autumn harvest and autumn planting.
Hubei Chibi: The Secret of Increasing Yield in Smart Farms
The harvest of more than 30 million mu of medium rice in Hubei Province has come to an end, and rapeseed sowing has been carried out simultaneously. In Chibi City, Xianning, Hubei Province, agricultural machinery equipped with Beidou terminals shuttles through the fields. In addition to the smart field management system, what new measures will be taken to improve grain yield? According to the "one map" of Hubei agricultural machinery we just saw, we went to the field to make a visit.
The reporter came to the thousand-acre smart farm in Yangloudong Town, Chibi City, Hubei Province, and the farmland behind him had just finished harvesting rice, and now he was sowing rapeseed, and the agricultural machinery running in the field was equipped with the Beidou terminal. Through the Hubei Beidou Smart Agriculture Management and Service Platform, we can see the movement trajectory of these three agricultural machines and the number of acres of operation. It is understood that the accuracy of agricultural machinery after being equipped with Beidou terminal has reached the centimeter level, and the sowing is more accurate, which can save seeds and fertilizers. The reporter learned from the local agricultural and rural departments that the rice yield of this demonstration field reached more than 1,100 catties this year, an increase of 200 catties compared with last year. For mountainous land, this increase in yield is hard-won.
"Metamorphosis" is staged by Oda and Ota
In addition to smart management, there are also a series of measures such as "small fields and large fields" and "comprehensive management of small watersheds". This farmland in the aerial perspective is a pastoral beauty with fields in squares, roads into networks, and canals connected, which was not the case in the past. The two pictures in the reporter's hand, above are the appearance before "Oda and Ota Field", and you can see that the fields of each family are extremely irregular, with triangles and many irregular shapes. And through the "small field and big field" initiative, the irregular fields were put together into regular fields. One of the great advantages of this is that it can be planted in a concentrated and continuous manner, which is conducive to mechanized operations. Local farmers told reporters that in the past, a plot of land here could only be rented for 180-200 yuan a year, but now the rent can reach up to 440 yuan, which increases the rent of the land and increases the income.
The "crop rotation model" has high benefits, and the comprehensive management of small watersheds is the key
This is also the first time that the local rice is harvested, and then rapeseed is sown, realizing the rotation mode of planting one season of rice and one season of rape a year, which also benefits from the comprehensive management of the small watershed of "Yanglou Donggang" in the past two years. In the past, due to the old water conservancy facilities, the farmland here could not be watered by drought and drained by waterlogging, so only one season of rice could be planted, and in winter it became an idle field. Today, thanks to the integrated management of small watersheds, connected ditches and abundant irrigation water, the conditions for growing two crops a year are now met.
Crop breeding in mainland China has officially entered the stage of intelligent breeding
The reporter learned from the Chinese Academy of Agricultural Sciences that a few days ago, the mainland's first intelligent field plant phenotype accurate identification platform was completed in Hainan, marking the mainland's crop breeding officially entered the stage of intelligent breeding.
"Plant phenotype" simply refers to the various characteristics of plants, including the appearance of plants, as well as some internal physiological characteristics, such as resistance to drought and disease. The large-scale equipment that is shuttling in the experimental field in front of you is the accurate identification platform for the phenotype of plants in the field, which can be moved remotely according to the preset track. It has 6 sensors like "eyes" to scan plants at the same time, which is equivalent to a "CT machine" of plants.
Although the appearance of the frame looks simple, it contains six kinds of high-precision image acquisition equipment such as multispectral, thermal infrared, and chlorophyll fluorescence, which can be collected at regular intervals and fixed points according to the experimental needs, and the collection of germplasm materials can be completed within 30 seconds.
After the data collected through this platform is transmitted to the data analysis center, researchers can screen germplasm resources with excellent traits more quickly and accurately, laying the foundation for subsequent crop breeding work.
