Technology empowers to stabilize the "vegetable basket"

Solar greenhouses, plastic greenhouses... All kinds of facility agriculture are not unfamiliar to Chinese people. With the help of facility agriculture, all kinds of vegetables, fruits and flowers enrich people's dining table and life despite the cold and heat.

Facility agriculture makes a significant contribution to vegetable supply

"Facility agriculture is actually a way to optimize and create an environment suitable for animal and plant growth and increase its yield by changing natural resources such as light, temperature, water and soil through artificial technology. By building a solar greenhouse and introducing matrix cultivation, water and fertilizer integration, Network control and other technologies have formed Gobi agriculture of hundreds of thousands of acres. It is precisely relying on facility agriculture that northwest dryland agriculture has become the fastest growing area of grain production in China. Another example is the highly integrated modern facility agriculture - plant factory , which integrates biotechnology, engineering technology and system management, so that agricultural production can be freed from the constraints of resource production.

my country is a veritable nation of facility agriculture. Data show that my country's facility agriculture area reaches more than 42.7 million mu, accounting for more than 80% of the world's total facility agriculture area, of which facility vegetables account for 81%. "The combination of production in these facilities and open-field production, combined with market allocation and transportation and circulation system, basically meets the annual supply of vegetables in my country, and also makes the history of the people in the north who can only eat cabbage, radishes and potatoes in winter is gone forever. contribute.

In terms of layout, my country has gradually formed five advantageous production areas for facility vegetables in the Huanghuaihai and Bohai Rim, the middle and lower reaches of the Yangtze River, the Northwest, the Northeast, and South China. In terms of facility types, my country mainly focuses on solar greenhouses, plastic greenhouses and small and medium-sized arched sheds with less investment, energy saving and cost saving. Among them, the solar greenhouse is an original creation in my country, which can be used for overwintering cultivation of fruits and vegetables without heating in areas with a minimum temperature of -28 °C (43.5 degrees north latitude), providing a "Chinese model" for the world's agricultural energy conservation, emission reduction and green development.

Scientific planning and guidance to strengthen scientific and technological support

With the in-depth integration of modern information technology and agriculture, three major systems should be built with the main line of "data-knowledge-decision-making" to solve the problems of where data comes from, how to deal with it, and how to use it.

The first is to strengthen the innovation of precise perception and data collection technology, and build an agricultural and rural information collection technology system that integrates "sky and earth". By carrying out research on data collection, input, aggregation, application, and management techniques, the ability to acquire and process raw data will be improved.

In addition, accelerate the research and development of professional remote sensing satellites to meet the needs of agriculture and rural areas, make breakthroughs in common key technologies for agricultural applications of drones, and realize cross-regional, all-factor, and multi-level data on important mountain agricultural resources, environment, production, operation, management, and services. collection.

The second is to strengthen the innovation of data mining and intelligent diagnosis technology, and build a technology system for intelligent processing and analysis of agricultural big data. Focus on strengthening the advance layout of strategic cutting-edge technologies such as artificial intelligence, virtual reality, blockchain + agriculture, and big data cognitive analysis.

Adhere to innovation-driven, improve comprehensive production capacity, establish a national facility agricultural science and technology innovation center, and set up a facility agricultural science and technology innovation special project. Strengthen the research and development and promotion of technical equipment such as facility structure, special varieties, agricultural machinery equipment, and green standardized production, and break through the bottleneck of high yield, high quality, and high efficiency.
