China's greenhouse agriculture has advanced 4 formats, how many do you know?

    Greenhouse (greenhouse), also known as conservatory. A facility that can transmit light, keep heat (or heat) and grow plants. With the development of economy and the advancement of science and technology, plastic greenhouses and solar greenhouses appeared in the 1970s and 1980s. Since the 1990s, China's facility agriculture has gradually developed into a large-scale, intensive and scientific direction, and its technical level has been greatly improved. From the overall development point of view, China's greenhouse agriculture has advanced to 4 formats:

    1. Plastic greenhouse

    Around 1960, plastic greenhouses appeared one after another in the field of agricultural planting in China. Compared with glass greenhouse, plastic greenhouse has the advantages of light weight, less amount of skeleton material, low shielding rate of structural parts, low cost and long service life. Its environmental control ability has basically reached the same level as that of glass greenhouses. The acceptance ability of plastic greenhouse users is much higher than that of glass greenhouses in the world, and it has become the mainstream of modern greenhouse development.

Because the greenhouse has problems such as plastic aging, weak structure, and weak resistance to wind and snow loads, at the same time, the vegetable planting technology is basically in the traditional criticism. It is not the development of modern agriculture.

     2. Solar greenhouse

    Solar greenhouse is the abbreviation of energy-saving solar greenhouse, also known as greenhouse. It is a type of greenhouse unique to northern my country. It is a greenhouse that is not heated indoors. It absorbs solar energy through the rear wall to achieve heat storage and release, and maintains a certain indoor temperature level to meet the needs of vegetable crop growth.

At the same time, the "solar greenhouse" industry, as the main body of my country's facility agriculture industry, has become the most profitable industry in agricultural planting in the past 20 years. Due to the solid structure of the solar greenhouse, it has become the main tool for the transformation of large-scale vegetable cultivation in the north.

       3. Multi-span greenhouse

    The multi-span greenhouse is an upgraded existence of the greenhouse. In fact, it is a super large greenhouse, which connects the original independent single-room greenhouse with scientific means, reasonable design and excellent materials. Many soilless cultivation plants are planted in the "vegetable music tube" soilless cultivation pipeline used in the greenhouse.

      4. Smart Greenhouse

    On the basis of multi-span greenhouses, at this stage, the popularization of artificial intelligence, big data, Internet of Things, traceability systems, soilless cultivation, LED lights and other technologies has improved the advanced speed of smart greenhouses.
