Smart greenhouse has good light transmission performance, high light utilization rate; fast temperature increase and good heat preservation performance; easy to operate and ventilate and exhaust moisture, easy to manage; solid structure, good wind and rain resistance, long service life; easy to build, and relatively low investment. What are the specific performance of intelligent greenhouse construction standards?
Intelligent greenhouse construction should be selected in good geological conditions, moderate water table, drainage and irrigation convenience, no high mountains in front and east and west sides and tall buildings to block. Avoid flooding, flooding, mudslides and hail and wind gusts, pollution and other locations. Supporting the planning and construction of water supply and drainage, roads, electricity and other facilities.
Greenhouse spacing in the Hulbao area is generally between 3 times the height of the building in front, the spacing is too small winter shade easily, resulting in insufficient light, spacing too large land utilization rate decline; greenhouse should be built in the north-south direction, and 3-5 degrees to the west is good. Such a direction, receive sunlight for a long time, high utilization of light energy. If the terrain and other reasons, can not meet the above requirements, should also try to adjust. In the use of gong plate positioning attention to the different magnetic declination around, with the actual angle minus the magnetic declination and then 3-5 degrees to the west.
Greenhouse wall is the more major component of the greenhouse, it can not only support the closed greenhouse, play a role in insulation, but it also has the daytime accumulation of heat, the night release of heat, the role of stable greenhouse temperature at night. Wall structure in general we use thick wall structure way: using brick sandwich earth structure, with two 24cm brick wall in the middle sandwich 1 meter wide earth; machine built wall structure, generally for the lower width of 5-6 meters, the upper width of 2-2.5 meters between the paste earth crushed and made, three walls, one side to the sun. The ground inside the greenhouse is dug down type ground, generally dug down between 0.5-1 meters, greatly improving the insulation effect.
The height and north-south span of the greenhouse should be determined according to the local latitude. Because the height and span determine the angle of the greenhouse lighting surface, the angle of the lighting surface and the size of the sunlight incidence angle. To ensure the sunlight has a large incidence, the angle of incidence should be less than 40 degrees. Because the projection rate of sunlight is closely related to the angle of incidence of light. The angle of the greenhouse light surface should be properly increased by 5-6 degrees is good. The sun height angle is determined by the latitude of its location, and the sun height angle is different in different areas due to the different latitudes in which it is located.
Energy-saving solar greenhouse, its something 60-80 meters long is more appropriate, if the length is shorter than 60 meters, the greenhouse volume is small, insulation performance is reduced, encounter cold weather, indoor susceptible to cold damage or frost damage, and the relative cost is high. If the length of more than 80 meters is not convenient to manage, part of the equipment running problems.
Solar greenhouse skeleton type more, there are bamboo rod skeleton, concrete skeleton, round steel skeleton, flat steel skeleton, a few word steel skeleton, etc.. Through years of practice and summary, the current use of hot-dip galvanized round steel upper and lower using special connectors to connect the skeleton and hot-dip galvanized 3 * 8 flat steel one-time bending skeleton from the cost, strength, service life and beauty is more reasonable.
To use light transmission, drip-free, dustproof, good insulation performance, and has a strong tensile strength, long life of multifunctional composite film. The better ones are polyethylene long-life drip-free film, three-layer co-extruded composite film, polyethylene drip-free translucent film, ethylene - vinyl acetate three-layer co-extruded drip-free insulation and anti-aging film, PVC drip-free film, etc.
