From "Knowing how to farm" to "Smart farming", smart agricultural technology helps build the Granary

Since the establishment of the smart unmanned farm here, professional cooperatives and large grain growers have tasted the "sweetness" of smart agriculture. Relying on Beidou satellite navigation, 5G and other technologies, the 

3,000 acres of arable land in the core area of the smart unmanned farm has achieved unmanned operations in the key links of plowing, planting, management and harvesting, and the farmland environment is monitored in real time 

around the clock. In the Changping Agricultural Machinery Operation Professional Cooperative in Xindu District, various agricultural machinery are parked neatly, some of which are hung with cameras and a control panel is mounted 

in the cockpit. This is the unmanned agricultural machinery. "I have seven or eight agricultural machinery that have been transformed into intelligent ones. For example, unmanned tractors, rice transplanters, harvesters, etc., are very 

easy to use." He did some calculations. Taking the unmanned rice transplanter as an example, it used to require one person to drive and another person to place the rice seedling tray, but now only one person is needed. "The route it 

plans is more reasonable than that of our experienced agricultural machinery operators." Grower said happily, "It saves labour, fuel and time, and can save more than 300 yuan a day in total."

The chief planner of the rural revitalization of Agriculture and Rural Affairs said that a customized 5G network transmits images of agricultural machinery in real-time, and then through AI recognition, analysis, and calculation, unmanned 

agricultural machinery can operate freely in the fields. According to expert calculations, compared with manual driving, unmanned agricultural machinery can increase land utilization by 2%, which is equivalent to adding 60 acres of 

cultivated land in the core area. According to reports, this year, the measured rice yield per mu in the core area of the smart unmanned farm reached 730 kilograms, an increase of 50 kilograms year-on-year. Farming costs are reduced 

and ecological benefits are also emerging. Relying on precise meteorological monitoring and agricultural "four emotions" monitoring, smart unmanned farms realize intelligent management and control and precise planting. A big screen 

is more than 2 meters high, and 11 window interfaces continuously update the various "physical conditions" of Datian. This is the "brain" of the smart unmanned farm - " Smart Farm Cloud Platform”. More than 300 sensors are distributed 

in rice fields, irrigation stations and other places in the core area. They collect soil moisture, temperature, light intensity and other data in real-time, and carry out precise pesticide and fertilization, which can significantly save pesticide and 

chemical fertilizer investment. From "knowing how to farm" to "smart farming", the deep integration of science and technology and agriculture can realize "harvesting food in the ground and storing food in technology", and accumulate 

momentum for building a higher-level Granary. The chief planner said that in the future, smart unmanned farms will also realize new business formats such as production-marketing docking and direct agricultural and commercial supply, 

shortening the circulation of agricultural products, and benefiting both growers and consumers.
