New concept of modern agriculture

Introduction: 1 Urban Agriculture: the concept of "urban agriculture" was first proposed by some American economists in the 1950s and 1960s Urban agriculture in city countryside (hereinafter referred to as "agriculture in city countryside") refers to the operation of agricultural land in the metropolitan area It refers to the use of rural landscape, natural ecology and environmental resources, combined with agriculture, forestry, animal husbandry and fishery production, agricultural business activities, rural culture and rural life, to provide places for people to enjoy leisure tourism, experience agriculture and understand rural areas in the urbanized areas In other words, urban agriculture is an industry that combines the production, life and ecological functions of agriculture The characteristics of urban agriculture are mainly shown in the following aspects: A: the scope it covers refers to the agriculture in the gap between the urban urbanization area and the surrounding areas, which is different from the general suburban agriculture B: the production, circulation and consumption of urban agriculture, the spatial layout and structural arrangement of agriculture, and the relationship between agriculture and other industries must first comply with the needs of the city and serve for this purpose The development of agriculture is determined by the needs of cities, which reflects the dependence of metropolises on agriculture, and then realizes the integration of interdependence, complementarity and mutual promotion C: urban agriculture is not only the development of economic functions, but also the development of ecological and social functions, so as to realize the full function of agriculture D: the mode of agricultural production and operation is obviously a highly intensive mode of operation, realizing the integrated development of production, processing and sales, and then achieving a high agricultural development form and special functions of serving the city 2 Leisure agriculture (or sightseeing agriculture): a comprehensive leisure agriculture area Tourists can not only visit, pick fruits, experience farming, understand farmers' life and enjoy local interests, but also accommodation, vacation and recreation The basic concept of leisure agriculture is to use rural equipment and space, agricultural production sites, agricultural products, agricultural business activities, natural ecology, agricultural natural environment, rural human resources, etc through planning and design, to play the role of agriculture and rural leisure tourism, increase people's experience of rural and agriculture, improve tourism quality, improve farmers' income, and promote agriculture A new type of agriculture developed in villages In addition to the activities of picking, selling, watching, fishing and playing, part of the labor process of sightseeing agriculture can allow tourists to participate in and experience in person The rich local cultural relics, folk customs and historic sites and other cultural resources in rural areas can be visited Through the form of education and entertainment, participants can cherish the natural and cultural resources in rural areas, and arouse people's love of labor The interest of loving life and nature further strengthens people's consciousness of protecting nature, cultural heritage and environment 3 Plant factory: plant factory refers to the system of annual production of plants using high technology of environmental control and automation, including soilless cultivation, plant cloning and other technologies, as well as industrial production system of plant cell and tissue culture In 1957, the world's first plant factory was born in Denmark In 1974, Japan and other countries also gradually developed 4 Agricultural science and Technology Park: It refers to the modern agricultural science and technology demonstration area or the intensive area of modern agricultural science and technology enterprises, which has a strong demonstration and driving effect on regional agriculture and rural economy in a certain region, with the three high-tech agriculture as the goal, the adjustment of agricultural structure as the breakthrough point, the advanced applicable technology as the support, and the extensive participation of the government and other social forces 5 Factory agriculture: The concept of "factory agriculture" was first put forward by the former State Science and Technology Commission when it launched the project of "factory high efficiency agriculture" major science and technology industrial project in 1994 Before that, agricultural experts usually referred to the agricultural production mode of "using artificial facilities and manually controlling environmental factors to obtain the most suitable growth conditions for plants, so as to extend the production season and obtain the best output" For facility agriculture, horticultural experts call it facility horticulture 6 Space plant production: NASA has applied the most advanced soilless cultivation technology in space to produce food necessary for human life in space After more than 20 years of research, it has been successful Its main purpose is to produce enough food in the smallest area under the condition of weightlessness to support the long-term survival of human beings in space The latest technology is: 10000 wheat plants can be planted per square meter (1.2 square meters of wheat is enough for one person to eat flour), the height of corn plant is only 40-50 cm, and the tomato plant is 100-120 per square meter At present, to support a person to live in space, food includes wheat, potatoes, beans, vegetables, etc it only takes 6 square meters for each person These crops generally take 50-60 days from planting to harvest 7 Biosphere 2: the earth where people live is called "biosphere 1"; a special building with a building area of 1.2 hectares will be built in the suburb of Tucson, Arizona, the United States, called "biosphere 2" In Biosphere 2, it imitates the ocean, rainforest, savanna, desert, Bush, temperate grassland and crop intensive cultivation area on earth The building has been built and tested for 7 years People rely on the agricultural facilities here to produce food, which is self-sufficient The food production can be 16 times higher than on the earth "Biosphere 3" and "biosphere 4" will be built in the north and south poles, "biosphere 5" is ready to launch on the moon, scheduled for 2020 (author:) share to feed
