Building More New Granaries (People's Current Review), Empowering China with Technology | Food | Technology
Practicing the concept of big food, developing food resources comprehensively and through multiple channels, gathering the driving force of technological innovation, and transforming resource advantages into industrial advantages
In the East China Sea, the world's first 100000 ton smart fishery large-scale breeding factory ship "Guoxin 1" anchored here. Almost all the processes from fish fry entering the cabin, feeding and breeding, catching to processing can be completed on this ship. Under the shipborne cabin farming mode, "Guoxin 1" can raise 3700 tons of fish per year, more than twice the total winter catch in Chagan Lake each year, making it a mobile marine ranch.
There is data indicating that China is the first major fishing country in the world to achieve a production of aquaculture products exceeding the total catch. In recent years, from storm resistant deepwater cages, offshore ecological fences to breeding factory ship, with information and intelligent technology enabling various marine breeding equipment, China has constantly accelerated the pace of farming, breeding and fishing. In terms of development space, expand from nearshore shallow water to deep and distant sea; In terms of production methods, there is a transition from traditional aquaculture to modern industrial production. By continuously building a "blue granary" and a new base for high-quality protein production, more and more high-quality fish are "swimming" on people's dining tables.
Practice has taught us that solving the problem of food cannot simply focus on limited arable land.Scientific development and utilization in protection can help alleviate the shortage of land resources, enrich the dietary structure of residents, and improve the stable and safe food supply level in China.
In summary, as a major aquaculture country, there is still great potential and space for improvement in seeking food from rivers, lakes, and seas. Looking towards the future, we should balance market demand and environmental carrying capacity, and achieve the goal of raising more and better fish. On the one hand, it is necessary to scientifically expand suitable fishing areas, fully utilize inland water resources such as lakes, reservoirs, and rivers, optimize and upgrade production methods, and deeply tap into the production potential of intensive and three-dimensional aquaculture models such as industrialized circular water aquaculture and ecological net cages. On the other hand, we need to increase the selection and breeding of excellent seedlings, increase the research and development of aquatic "chips", and make efforts in practical aquaculture technology, processing and circulation, so that "vegetable baskets" can be filled with more high-quality aquatic products.
In this year's No. 1 central document, "establishing the concept of big food" was included in the "pay close attention to ensuring stable production and supply of grain and important agricultural products". Beyond arable land and the ocean, 231 million hectares of forests and nearly 400 million hectares of grasslands are all sources of confidence that make China's rice bowl more abundant. It should also be noted that stimulating the potential of forest "grain depots" involves precise breeding, ecological cultivation, and deep processing, and urgently needs to cultivate a green supply chain for ecological production; Developing and utilizing grasslands to fill "meat plates" and "milk bottles" requires a particular focus on balancing the contradiction between grass and livestock, and developing and promoting new technologies in feed production, breeding models, and resource utilization of livestock manure, in order to create a virtuous cycle of ecological aquaculture. In short, expanding the agricultural production space and opening up more food sources cannot be achieved without adapting to local conditions and reasonable layout. It is even more necessary to solidly promote the supply side structural reform of agriculture, demand output and production capacity from technological innovation, and play a good combination of punches.
From 80% of the food used to come from staple food, to the fact that meat, eggs, milk, fruits, vegetables, mushrooms, and aquatic products have become the main characters on the dining tables of urban and rural residents, these trends reflect the quietly changing food consumption structure of the people, and provide opportunities for accelerating the development of modern agriculture and creating characteristic industries. By practicing the concept of big food, developing food resources comprehensively and through multiple channels, gathering the driving force of technological innovation, and transforming resource advantages into industrial advantages, we can definitely build more new granaries and secure China's rice bowl.
