Agro Greenhouses

Types of Agricultural Greenhouses:

1. Multi-span film greenhouse
2. polycarbonate greenhouses
3. Venlo glass greenhouse

 

Applications of Greenhouses in Agriculture:

Greenhouses play a crucial role in agriculture by providing a controlled environment with optimal temperature, light, and humidity for the growth of plants. The use of greenhouses allows farmers to grow crops year-round, regardless of the external conditions.

Basic Components of a Greenhouse:

A greenhouse consists of several essential components, including greenhouse framing, covering material, ventilation systems, heating and cooling systems, irrigation systems, and shading systems.
The greenhouse adopts a strip foundation or an independent point foundation, with a depth of 80CM concrete pouring (change according to the actual land conditions), and a 0.5-meter-high brick wall skirt around it. Water distribution and external drainage ditches are designed around the greenhouse.

Greenhouse load values ​​refer to GB50009-2012 "Code for Building Structure Loads".
Design calculation software: China Academy of Construction Sciences PKPMCAD steel structure STS computer-aided design program. 2008 edition.
The main frame of the greenhouse is a light steel structure, which is independently processed by domestic high-quality hot-dip galvanized steel pipes and steel plates. The normal service life is not less than 20 years. The skeleton connections are all connected by galvanized bolts and self-tapping screws, without solder joints, which are both anti-corrosion and beautiful.

covering material
The top of the greenhouse is covered with 8mm solar panels, and the surrounding is covered with 5+6+5 insulating glass, and the surrounding facade structure is in the form.

 Aluminum alloy profiles and sealing strips
The covering material is fixed and sealed by the special aluminum alloy fixture and special rubber strip independently developed by our company, so that the greenhouse has good air tightness and aesthetics.
Aluminum alloy profiles: special for glass greenhouses, aluminum alloy EN AW6061 or EN AW6063, the surface of high-strength aluminum alloy profiles is anodized. Machining tolerances comply with EN-755-9 standard

Top opening ventilation system
Set a rack and pinion electric window ventilation mechanism on the top of the greenhouse. Opening windows at the top enables convection of air inside and outside the greenhouse to achieve the effect of dehumidification and cooling. The system is easy to maintain, economical and practical, and has reached the international advanced level. The top opening window adopts the form of single opening
 

Advantages of Different Types of Greenhouses:

1. Multi-span film greenhouse: Low cost, easy to install and maintain, suitable for a wide range of crops. It is mainly used in subtropical areas with high humidity and rainfall.
2. Linked Greenhouses: Offer a larger growing area and allow for ease of expansion. These are ideal for subtropical and tropical areas with high rainfall.
3. Thin film sunlight greenhouse: Cheap, portable and ideal for hobbyists. These are used primarily in cold regions with short growing seasons.
4. Venlo glass greenhouse: Offers excellent insulation, allows for better control of temperature and humidity, and is aesthetically appealing. They are used mainly in temperate and cold regions.

Common Soilless Cultivation Methods:
1. Hydroponics: In hydroponics, plants are grown in nutrient-rich water, and no soil is used.
2. Aeroponics: In aeroponics, plants are grown in the air with their roots sprayed with nutrient-rich solutions.
3. Aquaponics: In aquaponics, plants and fish are grown together in a closed-loop system where the fish provide nutrients for the plants.

Advantages of Soilless Cultivation:

Soilless cultivation methods offer several advantages, including water conservation, efficient nutrient delivery, and year-round farming in controlled environments.

Suitable Crops for Soilless Cultivation:

Soilless cultivation is suitable for growing a wide range of crops, including leafy greens, herbs, tomatoes, cucumbers, strawberries, and even flowers.
