The Advantages of An Agricultural Greenhouse
Agricultural greenhouses provide an excellent growing environment for crops.
01
Greenhouse provides an ideal environment for plants to thrive, regardless of the climatic conditions outside. The controlled temperature, humidity, and lighting that a greenhouse offers create the perfect conditions for plants to grow all year round. This means that crops can be grown in any season, giving farmers a consistent and reliable food supply.
02
Greenhouses help to protect plants from harmful insects, pests, and diseases. With proper maintenance and care, a greenhouse can significantly reduce the amount of damage that plants would have otherwise suffered if grown outdoors.
03
In a greenhouse, there is greater control over the soil's nutrients, which allows crops to flourish and produce high yields.
04
Greenhouses also offer a unique opportunity to connect with nature and develop a deeper appreciation for the environment.
In conclusion, the use of a greenhouse has countless advantages, from providing an optimal environment for plant growth to protecting crops from pests and diseases.
The agricultural greenhouse is a structure designed to efficiently trap the sun's warmth and light to create a carefully controlled environment for plants to grow. It typically consists of a translucent roof and walls made of materials such as glass or plastic, which allow sunlight to enter while preventing heat from escaping. The precise regulation of temperature, humidity, and air circulation in a greenhouse provides optimal growing conditions for a wide variety of plants, from tropical fruits to delicate flowers. Greenhouses are an important tool for modern agriculture, allowing farmers to extend growing seasons, increase yields, and cultivate crops in regions with harsher climates.
Components of Agricultural Greenhouse
A large vegetable agricultural greenhouse consists of several key components and systems These systems include:
Greenhouse steel frame as main structure:
Base Foundation
A greenhouse foundation, also known as a greenhouse base, is an essential component for constructing a successful greenhouse. It provides the foundation and stability for the entire structure, thereby ensuring that the greenhouse is durable and functional for years to come. A well-constructed greenhouse foundation is typically made up of sturdy materials such as concrete, brick, stone, or steel. These materials provide the necessary strength and stability to support the weight of the greenhouse and withstand external factors such as wind, rain, and snow. Specific considerations such as location, soil type, drainage, and wind load should be taken into account when designing the foundation to ensure its optimal performance.
The embedded depth of the independent point foundation in the greenhouse is about 0.6m under 0.000, and an independent foundation is adopted in the greenhouse. Around the greenhouse, 0.8 meters 0.8-meter-high brick wall skirt is set, of which 0.50m above ±0.000 and 0.3m below ±0.000 are reinforced concrete ring beams with a height of 300mm and a width of 250mm. The embedded anchor bolt at the top of the foundation and foundation beam is used to connect the superstructure column. The greenhouse is surrounded by 80cm wide concrete to disperse water outside the greenhouse water distribution facilities outside the drain. Greenhouse foundation civil engineering, around the drainage ditch can be built by the owner. The design is based on the national standard "code for design of building foundation" (GB J50007-2002)
Greenhouse Steel Frame
A greenhouse column is a very vital component of the greenhouse structure. It is typically made of sturdy and durable material, the agricultural greenhouse column uses square tubes in common.
All steel structure materials used in the greenhouse are made of national standard high-quality black steel.
All columns, trusses, and other components and joints are processed and welded first, and then hot-dip galvanized;
Site assembly, no welding.Metallic coatings-- Hot dip galvanized steel all other steel parts and fasteners shall be made according to GB/T 13912-2002 Metallic coatings-- Hot dip galvanized steel
The connecting fixed parts are mainly used in line with the GB5782 standard and are treated by hot dip galvanization. The service life of the main structure of the greenhouse is not less than 20 years.
(1) Specifications of main profiles:
Foundation: the strip foundation with a low wall of 0.8 meters high is adopted around the greenhouse, and the independent point foundation is used inside.
(2) The greenhouse framework is a light steel structure, which is made of domestic hot-dip galvanized steel.
The columns adopt 50*100*3.0mm hot-dip galvanized rectangular pipes.
The end columns adopt 50*50*3.0mm hot-dip galvanized rectangular pipes.
The side auxiliary columns adopt 30*50*2.0mm hot-dip galvanized rectangular pipes.
The girders adopt 50*50*2.0.mm hot-dip galvanized rectangular pipes.
The arch pipes adopt 32*1.5mm round pipes
The external awning columns adopt 50*50*2mm hot-dip galvanized rectangular pipes.
The external sunshade bars adopt 50*50*2mm hot-dip galvanized rectangular pipes
The external sunshade longitudinal bars adopt 50*50*2mm hot-dip galvanized rectangular pipes.
The thickness of the galvanized layer of the main frame of the greenhouse is 0.06-0.08mm, GB/ t3091-93 is used for hot dip galvanized.
The gutter is made of B=2.0mm thick cold-bending hot-dip galvanized steel plate, and the slope of the water gutter is 2.5‰ for drainage.
Each connector adopts a hot-dip galvanized bolt.
Greenhouse Shading System
Inside the shading system and thermal insulation system to shade and cool the temperature and regulate the growth of crops in summer, this project is combined with the external shading system.
In summer, because the solar radiation heat load into the greenhouse is too high, although the greenhouse with ventilation, the greenhouse of high temperature, low humidity environment is unfavorable for crops growing.
The indoor temperature can be controlled to only 1 degree higher than the outdoor temperature in the greenhouse with good ventilation. But about the outside shading system, due to blocking some solar radiation from entering the greenhouse, through
high-strength black UV polyester line is used, external shading screen with a shading rate of 75%.
Good shading effect in summer, good heat preservation effect in winter, and low operation cost.
According to the customer's requirements, the inside shading system and the outside system can all be adopted. The customer can also choose between the inner and outer shading systems.
Greenhouse Cooling System
Wet curtain fan cooling system
A wet curtain and fan system is a means of forced cooling in a greenhouse in summer.
In the cooling system of a wet curtain fan, the sensible heat in the air is changed into latent heat when water evaporates. More water evaporates
Less is proportional to the difference in saturated vapor pressure of the air.
The drier the air, the higher the temperature, and the greater the cooling range of air through the wet curtain.
Working principle: the wet curtain is installed on the gable or side wall at one end of the closed greenhouse, and the fan is installed on the gable or side wall at the other end. When the fan draws air, the indoor negative pressure is generated, forcing the outdoor unsaturated air to flow through the wet curtain
When the surface is moistened, a large amount of sensible heat in the air is converted into latent heat, which forces the dry bulb temperature in the indoor air to drop by 4 ~ 12℃, and it is continuously introduced into the room for heat prevention and cooling.
In the gable of the end mountain of the greenhouse, a single fan with a flow of 42000m3/h is used to resist the strong wind, with 1-2 fans per span.
Greenhouse Covering Material
Glass greenhouse cover 4mm glass on the roof and side wall can be 4mm single layer glass or hollow glass on the 4 sides surrounding glass.
Polycarbonate greenhouse always covers 8mm polycarbonate board on the roof and side walls. Polycarbonate with low cost, good warm keep, and 10 years lifetime, etc advantages.
Multi-span film greenhouse always covering film, can be 150-micron film and 200-micron film, PO/PE film is clear or blue, with UV treatment, lifetime is 3 to 5 years.
Drainage System
The greenhouse is made of hot-dip galvanized steel gutter.
Gutter and gutter connection use gutter adhesive.
The greenhouse will be built by the two-way slope. To prevent freezing cracks in water pipes in winter, the rainwater will be drained from the gable columns to the gutters built by users.
The designed maximum displacement is 140mm/h (5min duration).
Pipes: GB 50268-97 code for construction and acceptance of water supply and drainage pipes GB/T 10002.
