What are the common types of vegetable greenhouses?

1. Simple bamboo shed: Simple bamboo shed is the most extensive type, with a shed width of 5 to 6 meters and a ceiling height of 2 to 3 meters. Its advantages are convenient material acquisition, easy construction and low cost, with a cost of about 3,111 yuan per mu. Its disadvantages are many columns in the greenhouse, high shading rate, inconvenient operation and short service life.

2.8-meter-wide enhanced steel frame greenhouse: This greenhouse is made of galvanized pipes with a diameter of 28 to 32 mm and a thickness of 1.5 mm, and the top is 3.2 to 3.5 meters high. The whole greenhouse has a large space and is suitable for planting tall vines. Its advantages are sufficient height and width, and successful improvement of management efficiency, land utilization rate and thermal insulation in winter. Its disadvantage is high construction cost, which costs about 21 to 45 yuan per square meter and 1.5 to 31,111 yuan per mu. It is more suitable for agricultural demonstration parks and farms with certain economic strength.

3. Steel-bamboo mixed greenhouse: The structure of the steel-bamboo mixed greenhouse is the same as that of the simple bamboo frame greenhouse, and the combination of steel pipes and bamboo frames has the advantages of saving steel, reducing the cost and being convenient to operate. Moreover, this kind of greenhouse is firm and has a long service life.
