Materials of Holland vegetable greenhouses

The Holland vegetable greenhouse is one of the most advanced agricultural technologies in the world. In order to create the best planting environment, the design, material selection and installation of the greenhouse need to be carefully planned and implemented. Here is more detailed information about greenhouse materials:

1. Glass material: Glass is the most widely used type of greenhouse covering material. In the Netherlands, glass greenhouses usually use tempered glass, which is 4-5 mm thick and has high impact resistance and strength. Tempered glass can withstand bad weather such as wind, rain, snow, and prevent strong light exposure. It can also increase the humidity in the greenhouse and provide a comfortable environment for plant growth. Glass materials are more expensive than plastic materials, but their service life is more than 20 years, so it is a viable option for large plantations with long-term use.

2. Plastic materials: Plastic is another widely used material in greenhouse covering materials. Vegetable greenhouses in the Netherlands usually use plastic films such as polyethylene or polyvinyl chloride. These materials have good light transmittance, waterproofness, and UV resistance. They also have the advantages of being light, easy to maintain and replace, and relatively low in price. However, plastic films are not as strong and durable as glass and usually need to be replaced every 3-5 years, so for large plantations with long-term use, replacement costs need to be considered.

3. Metal materials: Vegetable greenhouses in the Netherlands usually use aluminum alloys or steel to make brackets. Aluminum alloy is a lightweight, corrosion-resistant material with high strength and stability. It can withstand weight and various external forces in greenhouse supports and has good durability. Steel is stronger and more durable, but heavier and requires more powerful supports to carry it. Metal supports have a long service life and are a viable choice for large plantations that are used for a long time.

In general, the design of vegetable greenhouses in the Netherlands is very advanced, and the choice of greenhouse materials depends on different factors, such as budget, required light transmittance, thermal insulation, windproof, rainproof, insect-proof, safety, etc. There are many factors to consider, so designers will choose the best materials according to the specific situation.

In addition, the vegetable greenhouses in the Netherlands also use some advanced technologies, such as:

1. Automation system: The temperature, humidity, irrigation, fertilization, etc. in the greenhouse are all controlled and monitored by advanced computers. This automation system can ensure that the environment in the greenhouse is always in the best condition, improving yield and quality.

2. LED lighting: In order to provide sufficient light in winter and at night, the vegetable greenhouses in the Netherlands use LED lighting systems. This light can provide light in different spectral ranges, so that plants can obtain the required spectrum and intensity at different growth stages.

3. CO2 injection system: In order to promote plant growth, the vegetable greenhouses in the Netherlands use CO2 injection systems. This system can increase the CO2 concentration in the greenhouse, thereby improving the photosynthesis efficiency and growth rate of plants.
