What are the general types of vegetable greenhouses at present?

Growing vegetables in greenhouse has become the most popular way of growing vegetables, and many farmers are not clear about the types, cost, technology and other issues of vegetables in greenhouse. The seemingly simple vegetable greenhouse is not so easy for the first try. A series of questions about vegetables in the greenhouse are summarized here for farmers' reference.

1. Simple bamboo shed

Is a widely used type, the shed type is generally 5-6 meters wide, the top height is 2-3.2 meters, the side height is 1-1.2 meters, and the arch spacing is 1-1.1 meters. The utility model has the advantages of convenient acquisition, easy construction and low cost, with a cost of about 3000 yuan per mu (even thin film).

It is worth noting that there are many columns in the greenhouse, high shading rate, inconvenient operation, and short service life.

2, 6 meters wide prefabricated steel frame greenhouse

This type of shed has been popularized and applied for many years, mainly using galvanized thin-walled steel pipe with a diameter of 22mm and a thickness of 1.2mm as the skeleton material of the greenhouse, with a width of 6m, a top height of 2.2m, a shoulder height of 1.2m, a land utilization rate of 80%, and a service life of more than 10 years. The cost is 10-30 yuan per square meter, and the construction cost is 7000-20000 yuan per mu.

It is worth noting that this kind of shed is suitable for growing vegetables, flowers and so on, but it has the disadvantages of small width, low efficiency of operation and management, and weak insulation in winter.

3, 8 meters wide to improve the section steel frame greenhouse

This kind of Peng is made of galvanized tubes with a diameter of 28-32 mm and a thickness of 1.5 mm, with a top height of 3.2-3.5 meters and a shoulder height of 1.8 meters. It is suitable for growing high vine vegetables and so on. The shed not only increases the height and width of the shed body, but also increases the height and width of the ventilation window on the side of the shed, increases the space in the shed, improves the management efficiency and winter insulation, and improves the land utilization rate.

It is worth noting that the construction cost of this kind of greenhouse is greatly increased, the cost per square meter is about 20-45 yuan, and the cost per mu is 1.5-30,000 yuan, which is mainly suitable for agricultural demonstration parks and farms with certain economic strength.

4. Steel and bamboo mixed greenhouse

The shed structure is the same as the simple bamboo frame greenhouse, and the steel pipe and bamboo pole are used as arch bars at intervals, which has the advantages of saving steel, reducing cost and convenient operation, and has a certain application area; the performance and cost are between steel frame greenhouse and bamboo frame greenhouse.

5. Multi-span greenhouse

The multi-span greenhouse is a kind of upgrade existence of the ordinary greenhouse, in fact, it connects the original independent single-room greenhouse with scientific means, reasonable design and excellent materials, which can be understood as a kind of expansion. it has the advantages of large space and high land utilization rate, but the cost is much lower, 50-100 yuan per square meter.

The above are the five main types of growing vegetables in greenhouse, hoping to enhance farmers' understanding of growing vegetables in greenhouse!
