Plastic greenhouses are unheated, single-span arch roof greenhouses with plastic film as the covering material. Plastic greenhouses are easy to construct, easy to use, and have low investment. They are a simple protected cultivation facility. With the development of the plastic industry, it has been widely adopted by countries in the world. Plastic greenhouses are generally not heated indoors, relying on the greenhouse effect to accumulate heat. Its minimum temperature is generally 1 ~ 2 ℃ higher than the outdoor temperature, and the average temperature is above 3 ~ 10. The transmittance of the plastic greenhouse is generally 60% ~ 75%. In order to ensure the basic balance of the average light throughout the day, the layout of the greenhouse is mostly in the form of an extension from north to south.
Professional Design
The basic requirements for using a circular arched shed are 8 meters wide, 30 meters long, 1.8 meters high at the shoulders, and 3 meters high at the top. 04m or more. The material is made of hot-dip galvanized steel, and 3 longitudinal tie bars are designed to enhance the wind and pressure resistance. 4 longitudinal film-pressing grooves (2 grooves on each side) are designed. The skirt film is 40cm high, and the upper side is fixed with a film pressing groove, and the lower side is buried in the soil to enhance wind resistance and sealing. The second pass is installed 140cm off the ground, and the roll film and the skirt film repeat 30cm. 6 vertical poles are installed at the ends; a film-pressing rope is installed between the two arches of each raft to increase wind resistance, and windproof braces are installed at the four corners of the shed to increase the stability of the shed Door, door size is 1.8 × 1.4m, each seat total 2 pillar.
