Vegetable Greenhouse

 

The vegetable greenhouse is a laminated frame structure with excellent thermal insulation properties, and its appearance allows people to eat off-season vegetables. Generally, vegetable greenhouses use a bamboo structure or a skeleton of a steel structure covered with one or more layers of insulating plastic film, thus forming a greenhouse space. The outer membrane is a good way to prevent the loss of carbon dioxide produced by the growth of internal vegetables, so that the shed has a good insulation effect.

Vegetable greenhouse development history

China is an ancient agricultural country. Not only has vegetables have a long history of cultivation, but people have long used natural resources and environmental regulation. According to the literature, about 2,000 years ago, China had cultivated vegetables in protected areas, but the control technology at that time was very backward and the effect was poor. In the late 1980s, especially in the early 1990s, with the establishment of the Chinese market economic system and the adjustment of the rural planting structure, vegetables greenhouse have developed rapidly.

The most common types of arched skeleton greenhouses are classified according to arch materials
1.Bamboo raft skeleton greenhouse

Advantages: easy to draw material, easy to build, low cost.

Disadvantages: low arch frame strength, poor wind and snow resistance, easy to rot, need to be repaired and replaced every year, operation management is not convenient.

2.Composite skeleton greenhouse

Advantages: high shading rate.

Disadvantages: Poor pressure resistance, easy to break, difficult to use and promote.

3.Cement skeleton greenhouse

Advantages: moderate cost, easy to promote.

Disadvantages: insufficient span, limited ridge height, not suitable for mechanical in-line operation, current development slows down.

4.Steel pipe arch greenhouse

Advantages: high strength, strong wind and snow resistance, good anti-corrosion performance, high light transmittance, suitable for mechanical in-plant farming, convenient operation and management, and long life of 10-15 years.

Disadvantages: high cost, big investment in one time.

Choice of greenhouse location
1.Meet the standard production requirements

The greenhouse base must meet the requirements of pollution-free or green food and organic food production, avoiding some pollution sources to ensure the quality and safety of its products.

2.Sunward leeward

The terrain is open and the terrain is flat. There are no tall trees, buildings or mountain shading to ensure adequate illumination. Avoid the tuyere, the wind tunnel, the valley, the mountains and rivers. It is better to plant windbreaks or build houses to protect against leeward.

3.Deep soil layer

The soil layer should be deep, the soil should be fertile, and there is no salting; The groundwater level should be low. If the groundwater level is high, the soil moisture content is large, and the relative humidity in the shed is increased, which is likely to cause disease.

4.Easy drainage

The newly built greenhouse base is close to the water source, the water quality is good, the power supply should be normal, and the irrigation and drainage facilities should be complete to ensure that irrigation and drainage can be carried out all the time.

5.Convenient transportation

Convenient transportation is conducive to product distribution and establishment of the production market.
