Features： This system is to install a sunshade net inside the greenhouse. In summer, it blocks excess solar radiation indoors and allows sunlight to enter the greenhouse, evenly irradiating the crops, protecting them from strong light burns, and lowering the indoor temperature. If used in conjunction with the wet curtain fan cooling system, it can greatly improve the cooling efficiency, reduce the volume of indoor cooling and ventilation air, and make the air flow smoother. In winter and at night, the system can effectively prevent infrared rays from escaping, reduce heat loss, reduce heating space, and reduce heat energy consumption, thereby reducing the operating cost of the greenhouse. Choosing different sunshade nets and adjusting the opening and closing positions of the sunshade nets can form different sunshade and cooling effects. The system can effectively maintain appropriate indoor air humidity and anti-drip function, reduce irrigation water, meet the requirements of different crops for sunlight and the special requirements of crops in morphological structure and physiological function, thereby improving the quality and benefits of crops. Type of shading system： This system type and basic composition are basically the same as the external shading system, but there are some differences in the selection of shading nets include air-adaptive type and heat-insulating type. The air-adaptive shading net is a heat-insulating shading net with the polyester film strip removed. It is directly woven with aluminum foil strips and yarns to form an open-pore structure. Air can freely pass through the curtain without affecting ventilation. It is mainly used for naturally ventilated greenhouses and greenhouse cooling in hot climates. Its good air adaptability can maintain good effects even when the system is closed, minimizing the indoor temperature.

Why choose greenhouse？ Greenhouses have played an important role in the modernization of agriculture. Traditional planting methods are greatly affected by the natural environment. As the modern planting environment becomes increasingly severe, the application of greenhouses is becoming more and more widespread. So the question is why modern facility agriculture needs greenhouses, and what are the advantages of greenhouses? Ⅰ.Greenhouses can realize the production of out-of-season vegetables At present, the greenhouse can realize the early listing of spring vegetables and fruits, the delay of autumn vegetables harvesting, and the production of winter vegetables. The greenhouse achieves year-round vegetable supply by stagger vegetable production seasons, ensuring that fresh vegetable products can be eaten at the table of ordinary people at any time. Ⅱ. Greenhouses produce healthy vegetables Greenhouse through the creation of their own internal small environmental climate can maximize isolation of pests and diseases (greenhouse vent layout insect-proof net) and reduce outdoor dust, haze and other damage to plants. At the same time, greenhouses can reduce the damage of natural disasters to crops and produce high-quality pollution-free vegetables. Ⅲ. Greenhouse is high efficiency, energy saving Effective use of natural light energy in winter to produce high-quality out-of-season vegetables. The greenhouses use transparent covering materials to heat up fast and have good light. On sunny days, the temperature inside the greenhouse is more than 20 degrees higher than the outside world, and it is 2 to 3 degrees higher in the evening. Since the optimal temperature for most vegetable production is 20 to 30 degrees, and the minimum growth temperature is at least 5 to 8 degrees, winter vegetable production can be completed through greenhouse facilities. The daytime temperature difference in the greenhouse is large, the nutritional production period is long, the quality of the watermelon, melon and fruit vegetables produced is greatly improved, and the output is greatly increased. Ⅳ. Greenhouse can be mechanized At present, the vegetable greenhouses we have built in recent years can be combined with the Internet of Things control software system to achieve intelligent and automatic control of the sunshade, ventilation, cooling, heating, irrigation and fertilization of the greenhouses. The use of mobile phones and computers can really monitor and control the greenhouse in real time, which can save water, fertilizer, electricity and energy consumption while reducing labor.

Consultation and decision-making of early construction First, prior to the commencement of construction, preliminary consultation is essential, including feasibility study, investment evaluation and analysis, technology and practice, etc. The technical consultation of multi span greenhouse includes: cultivation or production mode, construction and operation scheme and design scheme. After technical consultation, the type, scale, structural form, equipment selection and design of heating, lighting, ventilation and cooling of the greenhouse will be determined. Some people will think that the intelligent multi span greenhouse is a widely applicable greenhouse. In fact, it is not. The greenhouse design varies greatly according to different planting needs, such as the environmental parameters required for planting orchids, seedlings or vegetables. The greenhouse can maintain normal operation through the operation of supporting facilities under the outdoor temperature of - 15 ~ 40 ℃, and the average light transmittance of the greenhouse should reach more than 70%; All steel structures must be hot-dip galvanized for surface corrosion protection; The greenhouse maintenance structure shall meet the water tightness requirements; The service life of the main structure of the greenhouse shall not be less than 15 years. Design and construction of greenhouse Foundation At the beginning of foundation, surveying and setting out is a key link. Because the superstructure components of the greenhouse are prefabricated parts, the accuracy of the plane position and elevation of the embedded parts on the foundation top will directly affect the quality of component installation. If it is not handled well, it will even cause rework. The greenhouse generally covers a large area, and the number and density of internal columns are much larger than those of other buildings. In order to improve the wind resistance of the greenhouse, an independent concrete foundation is adopted under the column, and the control of foundation top elevation is very important. Generally, it is required that all foundation top elevations should be measured and positioned continuously at one time, the supervisor's review should also be completed at one time, and detailed measurement records should be made at the same time. In this way, the error caused by instrument calibration and calculation can be avoided to the greatest extent. Main body installation precautions 1. Pay attention to on-site protection when materials enter the site to avoid semi-finished products from being damaged. 2. Strictly follow the construction sequence. The installation steps of superstructure are generally as follows: column (cable-stayed installation) - lattice frame - rain gutter - Roof Truss - purlin and ridge - internal and external sunshade transmission system - skylight - top PC board - facade PC board and side windows - curtain and power distribution system - greenhouse door - external sunshade Network - interna...

The role of shading system 1. Regulating temperature: in hot days, shading nets can effectively reduce the temperature inside the greenhouse and create a comfortable environment for plant growth 2. Control light intensity: reduce direct sunlight overheating burns leaves and plants water evaporation, prolong the survival period of crops, increase yields and improve crop quality 3. Energy saving: reduce the use of cooling equipment, reduce energy consumption and operating costs External shading of greenhouse Can reduce 3℃~8℃, depending on the shading rate and material of shading net Placement method: Horizontal at about 0.5m from the top of the greenhouse Or Directly covered on the greenhouse cover materials Inner shading of greenhouse Can be reduced by 2℃~5℃, depending on the shading rate and material of the shading net Placement method: Horizontally inside the greenhouse Or To be set along the sloping direction of the roof
