greenhouses are mainly divided into three categories according to covering materials: thin-film greenhouses, solar greenhouses, and glass greenhouses. In terms of cost: glass greenhouses>sunlight greenhouses>film greenhouses; the prices of these three types of greenhouses are generally at three basic levels: US$50, US$100, and US$150 per square meter. According to the conditions of each region, the profile and the intelligence of the greenhouse, the price is very high. Big difference.

 

The price of glass greenhouses is mainly consumed on profiles and labor. Except for labor, the profile materials are hot-dip galvanized pipes (current mainstream greenhouse materials), and the cover glass is determined according to the regional temperature difference. If the area is cold, the cover material is the side wall 6+5 +6 ordinary float glass, 5mm anti-reflection glass on the top, 5+6+5 ordinary float glass on the warm side wall of the project, and 4mm diffuse scattering glass on the top. It can effectively ensure the uniform light inside the greenhouse and has a certain heat preservation effect. Compared with other types of greenhouses, glass greenhouses have a crystal clear appearance, sturdiness and durability, strong wind and snow resistance, a life span of more than 20 years, and a lower maintenance cost for the greenhouse.

What are the characteristics of glass greenhouses compared to other greenhouses?

 

1. High planting density

Most of the glass greenhouses are soilless cultivation techniques, vertical planting, covering a small area, and the planting density is about 2-3 times that of ordinary greenhouses.

2. Strong disaster resistance

 

The main covering material on the top and surroundings of the glass greenhouse is tempered glass. Compared with ordinary plastic and PC board greenhouses, it is more resistant to natural disasters and will not affect the growth of crops by severe snowstorms.

3. Long service life

 

The service life of the glass greenhouse is about 20 years, and the covering material does not need to be replaced. Compared with the frequent replacement of the roof covering material in the ordinary greenhouse, it saves 20% of the input cost. Ordinary thin film greenhouses have a life span of six months to one year, solar greenhouses 1.5-3 years, and glass greenhouses start at 15 years.

4. Easy to clean

 

The glass greenhouse is stained and resistant to cleaning. It has a high degree of mechanization and can be washed at will.

At present, the main covering materials for glass greenhouses are: diffuse scattering glass, anti-reflection glass, AR glass, etc. The special cleaning agent for greenhouse glass can keep the light transmittance of the greenhouse glass unchanged, and increase the light intensity inside the greenhouse to extend the light time within a day. Promote plant photosynthesis, extend the average daily light duration by 3 hours, and increase the yield per mu by about 20%.
