The Rise and Development of Plastic Vegetable Shed in China

Plastic vegetable sheds, including plastic medium and small vegetable sheds and plastic vegetable sheds, are simple cultivation facilities. Because of its easy construction, convenient use, small investment and remarkable effect, it is widely adopted by countries all over the world.

Plastic vegetable sheds can make full use of solar energy, have a certain heat preservation effect, and can adjust the temperature and humidity in the vegetable shed within a certain range. In the northern part of my country, it mainly plays the role of thermal insulation cultivation in advance of spring and late autumn, and cannot be used for overwintering cultivation; in southern China, in addition to thermal insulation cultivation and overwintering cultivation in winter and spring, summer and autumn can also be used for shading and cooling Cultivation for protection against rain, wind, and hail.

The use of plastic vegetable sheds for vegetable cultivation in my country began in the mid-1950s. At that time, my country introduced agricultural polyethylene film from Japan, and developed small and medium-sized plastic arch shed cultivation on a large scale based on traditional technologies such as wind barriers, positive borders, and hotbeds. In the early 1960s, Shanghai and Beijing successively produced agricultural polyethylene and polyethylene film, which greatly promoted the rapid development of plastic shed cultivation in my country. In 1965, my country's first bamboo-wood structure plastic greenhouse was built in Changchun City, Jilin Province, which played a positive role in demonstration and promotion. In the 1970s, reinforced concrete structures and steel welded truss structure plastic greenhouse were successively developed; and they were promoted from the north to the south. In the 1980s, the Beijing Institute of Plastics successfully developed low-density long-life polyethylene agricultural film (LDPE); the Ministry of Agriculture developed “Hot-dip galvanized steel pipe assembly plastic greenhouse”, “Plastic greenhouse comprehensive cultivation technology research "A batch of related topics are included in the "Sixth Five-Year Plan" and "Seventh Five-Year Plan" key research projects of the Ministry of Agriculture, forming a number of technical achievements. The China Agricultural Engineering Research and Design Institute has developed a hot-dip galvanized steel pipe assembly plastic greenhouse , And fostered a number of professional designated manufacturers to form a series of products; In 1984, the national standard of "Assembled Steel Pipe Frame for Agricultural Plastic Shed" was issued for the first time, which has been in use ever since. The above factors promote the rapid development of plastic greenhouse cultivation in my country and become one of the mainstream facilities.
