Special multi-span greenhouse with hydroponics system and external shading system for seedling cultivation in multi-span greenhouse
The multi-span greenhouse is an arch-shaped greenhouse with a plurality of greenhouses connected. The span of each multi-span greenhouse is usually between 4 and 12 meters, the height is 3 to 5 meters, and the total area is several thousand square meters, even tens of thousands of square meters. The covered area of multi-span greenhouse is large, and the greenhouse temperature is stable. High-tech intelligent greenhouses are generally equipped with high automation facilities such as external sunshade system, internal covering system, internal thermal insulation system, wet curtain fan forced ventilation cooling system, top ventilation system, heating system, power distribution/control system, etc. During the working process of intelligent greenhouses, managers can input the data and control parameters required for planting crops into the computer, and the intelligent greenhouses can realize unmanned automatic operation, automatically control the greenhouse environment and ensure the growth of crops.
1. The main body of the multi-arch greenhouse:
the skeleton adopts double-sided hot-dip galvanized steel frame structure, and the top and side windows of the greenhouse can be artificially ventilated or closed according to the change of weather.
(1) Roof form: double arc arch type.
(2) skeleton: hot-dip galvanized low-carbon steel.
(3) Greenhouse frame: span 8m, bay 4m, arch bar spacing 1m, shoulder height 3.5m and top height. 5.5 meters, the external shading height is 6 meters.
2. Covering materials for multi-arch greenhouses:
(1) Top: The top of greenhouse is covered with PEP Lide film with a thickness of 0.15mm.
(2) Surrounding: The greenhouse is covered with PEP Lide film with a thickness of 0.15mm.
3. Ventilation system of multi-arch greenhouse:
(1) Ventilation at the top: There is a manual (electric) film rolling window at the top of the greenhouse with a self-locking device, which can stay at any height freely, and the film rolling stroke is more than 1.4m (8 at the top).
(2) Ventilation around: Manual film rolling windows are set around the greenhouse with self-locking devices, which can stay at any height freely, and the film rolling height is more than 1.8 meters. Every window is equipped with a 25-mesh insect net.
4. External sunshade system:
the steel skeleton adopts double-sided hot-dip galvanized steel frame structure, which has strong wind resistance, is driven by steel wire and runs smoothly. The motor adopts domestic products, and the sunshade net adopts black tiled net, with the sunshade rate of 70%. All the steel parts of the multi-arch greenhouse are hot-dip galvanized on the inner and outer walls, and the inner and outer walls are completely galvanized, with a thickness of 0.08mm, and there is no obvious sharp burr on the iron parts. All steel pipes meet the national standards.
5.Wet curtain-fan cooling system is composed of paper porous wet curtain, water circulation system and fan. When unsaturated air flows through the porous and moist wet curtain surface, a large amount of water evaporates, and the sensible heat reflected by temperature in the air is converted into latent heat of evaporation, thus reducing the temperature of the air itself. When the fan draws air, the cold air cooled by the wet curtain is continuously introduced into the room, so as to achieve the cooling effect.
6.Electric internal sunshade system:
1) cooling effect
2) heat preservation function
3) adjust the shading rate
4) Water retention and moisture retention
There are four common hydroponics techniques:
1.Deep flow technology, referred to as DFT(Deep Flow Technique)
2.Nutrient film technique, abbreviated as NFT(Nutrient Film Technique)
3.Floating capillary cultivation technique, abbreviated as FCH (Floating Capillary Hydroponics)
4.Fog culture technology, also known as spray culture and Aeroponics. SEED BEDApplication of hydroponics:
(1) for hydroponic vegetables Cultivating pollution-free green food, which is healthy and safe, is highly valued by people.
(2) used for hydroponics of flowers Hydroponic flowers have the advantages of cleanliness, sanitation and convenient maintenance, especially suitable for indoor decoration, and are deeply loved by consumers.
(3) used to cultivate medicinal plants Many medicinal plants are root plants, and the growth environment of roots is very critical. Hydroponics, especially fog culture, can provide a good growth environment for the roots of medicinal plants, so the planting effect is very obvious.Advantages of hydroponic vegetables:
1. Good product quality, safety and hygiene.
2. It can be quantitatively produced in a plant factory.
3. Regardless of the peak season, it is less affected by the natural environment.
4. Save fertilizer and do not need to change nutrient solution halfway.
5. High economic benefits.Product description of multi-arch greenhouse:Main Products
