Professional greenhouse insulation is recommended. Professional greenhouse insulation is recommended. China is a large agricultural country with a large population. Everyone is inseparable from fresh green vegetables throughout the year. At present, solar greenhouses are increasing rapidly, but the use and pervasiveness of plastic greenhouses have encountered some development problems that need to be solved urgently and scientific research. In order to make them develop more scientifically, we summarize a few questions encountered in the current use: ( 1) Most plastic greenhouse supports throughout the country are made of bamboo, wood layout or steel layout (galvanized steel pipe), but in the high temperature and high humidity environment where the greenhouse insulation is specific, it is easy to be corroded, which severely affects the service life. Usually, the bamboo and wooden supports need to be replaced from the beginning every 2-3 years; coupled with the continuous rise in steel prices, the cost of plastic greenhouses is severely increased, and it takes time and labor.

(2) Due to the randomness of the manufacture of bamboo and wooden greenhouse supports, the center needs to be supported by multiple pillars, which severely affects the operating environment in the greenhouse, making it unable to carry out large daylighting effects, unsuitable for mechanized operation, and increasing labor intensity.

Professional greenhouse insulation is recommended (3) Generally, the angle, slope, height and other conditions of the manufacturing of the bracket can not match the local geographic latitude, which reduces the use of solar energy. Or fire pit auxiliary equipment, so increase the human, financial investment and supporting power costs.

(4) Summarizing the above factors will affect the use and implementation of plastic greenhouses to a certain extent. In addition, the current prices of bamboo and wood steel are rising. Now the vast countryside urgently needs a new type of low price, corrosion resistance, humidity resistance, and aging resistance. In the light of bamboo, wood, and steel materials replaced by pillar-free greenhouse framework, our unit was entrusted by the relevant agricultural departments. Under the guidance of scientific research machinery and relevant professors from all parties, we completed the "Skeleton-free (greenhouse) greenhouse skeleton machine". For the key projects, the machine is equipped with a special formula developed by our unit, and the pillar-free greenhouse framework produced by our unit is of high quality and low price, higher quality than steel frame, and lower cost than bamboo and wood.
