The Chain Expo is the world's first national level exhibition with the theme of supply chain. Under the name and medium of chain, more than 500 enterprises and institutions from around the world showcase new technologies, products, and services in each link of the chain, seeking new opportunities for cooperation and development. The first Chain Expo set up five major chains and supply chain service exhibition areas, including intelligent automobile chain, green agriculture chain, clean energy chain, digital technology chain, and healthy life chain. Among them, the exhibition area of the green agricultural chain is about 14100 square meters, with 65 enterprises participating, showcasing core technologies, products, and services from the "countryside" to the "dining table" key links. Today's observation of time and space will focus on this chain closely related to the dining tables of ordinary people. Focusing on these issues, what is the green agricultural chain and what aspects are covered? In the green agriculture chain exhibition area, whether it is rice, flour, grains, oil, fruits, or fine wine, the green code of these high-quality agricultural products is hidden in their original appearance: seeds. Seeds are the "chip" of agriculture and the foundation of agricultural modernization. How do seeds affect the development of China's agricultural industry chain? This year's No. 1 central document mentioned that the seed industry revitalization action should be implemented in depth. What impact will the revitalization of the seed industry have on China's agricultural industry chain? As an agricultural powerhouse, China is both a supplier and a demander. What role does China play in the global agricultural supply chain? Follow CCTV reporters from the headquarters to take a look at the Green Agriculture Chain exhibition area. What is the green agricultural chain and what are the links it covers? Strolling through the exhibition area, the Green Agriculture Chain Exhibition Area of the Chain Expo is very different from the agricultural and agricultural product exhibition areas at other exhibitions in the past. What is the green agricultural chain and what are the links it covers? Green Agriculture Chain: From the fields to the dining table, I am a "small farmer" with the full name "Green Agriculture Chain". Your three meals a day are closely related to me. My biggest characteristic is "food at the end of the grain, work at the end of the farm". Simply put, it connects the entire process of food from the fields to your dining table. Agricultural research and development, production, processing, storage and transportation, sales, branding, experience, consumption, and services collectively constitute me. Green is my background color. Take corn as an example, in the sowing process, reduce the application of chemical fertilizers and pesticides, and use more organic fertilizers; The growth stage adopts water-saving technologies such as drip irrigation and sprinkler irrigation; After harvesting, straw can be used as feed or directly returned to the field. The green planting method has enabled us to obtain more green and high-quality agricultural products. Some agricultural products can directly enter the market; Others enter the deep processing stage. Intelligent manufacturing and preservation technology maximize the preservation of the taste and nutrition of agricultural products; In the circulation process, cold chain logistics connects the green channel for agricultural products; In the sales process, packaging reduction and biodegradable packaging will adhere to the concept of "carbon reduction" to the end. The cycle mode of turning waste into treasure has deepened my background. After fermentation, fruit peels and pomace can be transformed into animal feed. The wastewater and waste fertilizer produced by breeding farms can be treated and returned to the field as organic fertilizer. There are also ecological planting and breeding models such as fish vegetable symbiosis, fish rice symbiosis, shrimp rice symbiosis, and duck rice symbiosis. This entire green chain, from farmland to factories, from farmers to consumers, can be traced back to your dining table with the help of digital technology. The participation strung together by me
