When the most grounded agriculture meets the "above the cloud" meta universe technology, what changes will it bring? Recently, at the 2022 World VR Industry and Metauniverse Expo held in Nanchang, the Metauniverse Agriculture Exhibition Area attracted many people to stop and visit. The Yuan Universe Mall, the aerospace plant factory, and the robot collecting data... all these scientific and technological elements make people look bright. Not far from the Expo is the Yuanuniverse · VR Digital Agriculture Demonstration Base in Honggutan District, Nanchang City. The staff told the reporter that there is a similar base in the virtual space. "Through 3D modeling technology, the base covering an area of 346 mu has been copied in a 1:1 scale in the virtual world." Zhang Nandi, the chief engineer of the base, introduced that the meta universe is a new type of Internet application and social form that integrates a variety of new technologies, and its essence is to virtualize and digitize the real world. At present, this technology has been applied to the whole process of agricultural research, production, management and operation. It may take up to 14 years for a rice seed of space breeding to be industrialized from the start of space flight, but the process can be completed as soon as 4 years by using the technology of the meta universe. Zhang Nandi said: "We process, sort out and model the space breeding data for many years. If agricultural researchers need breeding experiments, they can set up various kinds of data in the meta universe laboratory, so that the data can 'run' in the model until the desired results are obtained. Planting offline according to the experimental data can further improve the model, so that the cycle can greatly shorten the experiment time and reduce costs." Through the integration and application of digital twins, digital traceability and other new technologies, agricultural greenhouses are changing greatly. In the No. 3 greenhouse where strawberries are planted, the reporter saw that some strawberries were turned over on the small "Ferris wheel", and some were "looped" on the hanging device. "Different strawberry varieties have different requirements for light, dormancy time and other growth conditions, so different equipment and environment are selected." Zhang Nandi explained that, for example, the strawberry varieties on the Ferris wheel need to supplement water and nutrients every three and a half turns. It is reported that the output of strawberry, tomato and other agricultural products grown in the greenhouse with fine control is more than 5 times higher than that in the ordinary greenhouse. At the agricultural product sales end, the meta universe technology has also brought changes. This base has been built into the Yuanuniverse Mall, which is different from the traditional e-commerce and the virtual farm in the game. It is a deeply immersive shopping environment. Meng Fanming, the person in charge of the base, said that the Yuan Universe Mall interacted with all the greenhouses of the base in real time. When you enter the mall, you can choose a suit of dress up, follow the digital people around the farm, click the camera to see the production scene, and deliver the goods home after purchase. "In the meta universe, agriculture can be used not only for recreation, but also for learning." Luo Juan, the person in charge of the research tutor of the base, said that she has received many groups of research teams to visit, further expanding the agricultural function and increasing the added value. "With the integration of virtual and reality, the space of imagination brought by the meta universe technology to agriculture is huge, and the future is worth looking forward to." Meng Fanming said.
