10 most common greenhouse greenhouse greenhouse pros and cons analysis, did you choose the right?

Greenhouses for vegetables, fruits, flowers Agricultural production activity cannot leave greenhouse more and more. The greenhouses can not only resist natural disasters, prevent cold and heat, resist drought and flood, but also be cultivated in advance, delayed cultivation, and extend the growing period of crops, so as to achieve the goal of early maturity, late maturity and stable production, which is very popular among farmers. Because the climate of each place and application are different, the specification of greenhouse greenhouse is not same, so cost is different also. Here let's talk about the advantages and disadvantages of greenhouse with the most common types of greenhouse, help each farmer friend more reasonable choice greenhouse greenhouse! Solar greenhouse greenhouse Solar greenhouse greenhouse is mainly divided into earth wall solar greenhouse and brick wall solar greenhouse. Recently, a third new type of solar greenhouse is developed, which is actually improved on the basis of the earth wall solar greenhouse. Earth wall solar greenhouse greenhouse Application: it is very suitable for the use of crops such as high-value vegetables. Specification: the span of earth wall solar greenhouse is usually 10-15 meters, and the wall structure is rolled and built with soil for many times, usually covered with 10-15 filament double-anti-dripping longevity film. Currently, the framework of the canopy is mostly made of all-steel welded structure. Advantages: the advantage of this solar greenhouse is that the greenhouse greenhouse cost is lower, the winter greenhouse insulation and heat storage effect is better, and the maintenance cost is lower in the later period. Disadvantages: the large floor area of the greenhouse greenhouse wall affects the net planting area of the greenhouse, which has certain requirements on soil quality. If the wall is not well protected, it is easy to be washed by rain and snow, which will affect its service life. A greenhouse with brick walls Application: used for vegetable, edible fungus, flower and fruit tree cultivation. Specification: brick wall of sunlight greenhouse span in 8 to 16 meters, the foam brick masonry wall structure of red brick or concrete, general wall thickness of 0.37 1 m, other structure and the basic of the retaining wall greenhouse, are made by full steel skeleton, covering film, heat preservation quilt, shutter mechanism into, if you use a few steel skeleton as support, canopy face greenhouses cost per meter can also reduce some. Advantages: solid and durable brick wall structure, with service life up to 20-25 years; The brick-wall solar greenhouse has high utilization rate of land and strong regional applicability. It is especially suitable for the construction in areas with complex geology, low water level and no masonry earth wall. Disadvantages: due to the brick wall structure, the greenhouse cost is higher than the earth wall solar greenhouse, and the investment return period is longer. New solar greenhouse greenhouse Applicable: such greenhouses are actually upgraded from earth walls and solar greenhouses. It is suitable for scientific research, breeding and seedling breeding, exhibition and other industries with high added value. Specification: the whole structure is consistent with the traditional solar greenhouse, with a span of more than 15 meters. The masonry of the wall part is made of earth wall and reinforced with cement mortar. The frame of the greenhouse is made of hot-dip rectangular tube with spring clamping groove. Advantages: the wall of the greenhouse is reinforced with cement mortar, which reduces the risk of collapse of the wall of the greenhouse, and increases the durability and service life by more than 5-10 years. The film on the surface of the shed is fixed by the clip spring groove, and it is convenient to replace the film in the future. Large span space, mobile seedbed, mobile sprinkler irrigation and other advanced equipment can be configured. Disadvantages: the wall covers a large area, the greenhouse cost is higher, reducing the cost performance of the solar greenhouse greenhouse, and the difficulty of popularizing is higher. To sum up, three kinds of solar greenhouse can be seen from the comparison of the three kinds of solar greenhouse. The cost of the earth wall solar greenhouse greenhouse is relatively low, and the maintenance cost is relatively low in the later period, which is the most cost-effective of the three kinds of solar greenhouse. For places where land is relatively abundant, it should be preferred to build the earth wall solar greenhouse greenhouses. 2. Single arch Single-building arch is also called arch plastic greenhouse and spring and autumn greenhouse. At present, it is mainly divided into three types, namely cement column arch, steel pipe simple arch, and new high-temperature arch. The new high-temperature arch due to the addition of thermal insulation measures such as thermal insulation quilts, the internal thermal insulation and heat storage effect of greenhouse is good, belonging to the high-temperature greenhouse, which can meet the winter production needs of low-temperature crops. Concrete arch Application: it is used for planting vegetables, flowers and other economic crops in spring and autumn. Specification: the span of the arch of cement column is generally 16-24 meters. The framework structure USES a mixture of steel pipe and bamboo pole, with 1 or 1.2 inch hot-dip galvanized steel pipe as the main arch, and USES cement column as the support, and then covers the film of the greenhouse. Advantage: this kind of canopy cost is lower, land use respect is more agile, smaller plot can build a canopy. Disadvantages: due to relatively simple skeleton structure, weak anti-snowstorm ability, indoor with columns, affecting the internal operating space. Steel pipe simple arch Configuration: the span is generally 8-14 meters, the framework is all made of hot-dip galvanized steel tube or rectangular tube assembly and welded, and the greenhouse is equipped with manual film coiler and pest control net on both sides. Advantages: the greenhouse has low cost, high strength and high land use rate. Disadvantages: weak thermal insulation and storage capacity can not meet the needs of winter production. It is suitable for vegetable, fruit, flower and edible fungus cultivation in spring and autumn. New high temperature arch Configuration: new type of high temperature tunnel is developed on the basis of the suggested that steel tube tunnel, span can reach more than 20 meters, reinforced frame structure is used in its general use 1.5 or 2 inches above the hot dip galvanized steel pipe or oval tube processing skeleton, canopy top two roller machine, shed surface heat preservation quilt cover special shelter, improve the greenhouses in winter heat preservation effect. Advantages: large internal space, simple and convenient maintenance operation, a certain thermal insulation effect in winter, able to carry out the production of four seasons. Disadvantages: the greenhouse is expensive and can only meet the growth demand of low-temperature plants. It is suitable for planting crops with low temperature in winter. In conclusion, the arched shed has the advantages of low cost, high land utilization rate and easy management, and is suitable for the cultivation and use of crops such as vegetables, fruits, flowers and edible fungi in spring and autumn. The high-temperature arched shed can also be used for the winter cultivation and protection of high value-added crops such as succulent plants and flowers. Three, even block arch greenhouses It is generally divided into simple jointed arch and high matching arch, which are mainly used in production greenhouse such as breeding and seedling, flower production, aquaculture, medicine and edible fungus cultivation. Simple arch Application: used in the cultivation of high value vegetables, flowers, medicine and edible fungus in spring and autumn. Configuration: its skeleton USES hot galvanization rectangular tube or circular tube, top is provided with gutter, end face is provided with ventilated window, same as the basic structure of the arched shed. Advantages: large internal space, suitable for large-scale factory operations, high land utilization rate. Disadvantages: high cost, low summer cooling efficiency, high requirements for drainage. High matching arch Application: used in three-dimensional cultivation, flower breeding, aquatic seedling, seedling, scientific research and other industries. Specification: high matching arch is an upgraded version of simple greenhouse, which adds internal and external shading, cooling of wet curtain fan, ventilation of side turning window, temperature increasing and heat keeping system on the basis of simple type. Advantages: it overcomes the temperature drop in summer and heat preservation in winter, especially after adding double-layer film, it can effectively improve the heat preservation effect of greenhouse in winter and reduce the operating cost in winter. Disadvantages: relatively high cost of greenhouses, suitable for industries with high economic efficiency; Without adding double layers of film, the heat preservation effect in winter is relatively general. Iv. Wenluo greenhouse Introduced from the city of wenluo in the Netherlands, wenluo greenhouse was initially used for the cultivation and use of high-value crops such as flowers. It is now the main type of greenhouse with facilities for the production and use of industrialized vegetables and flowers in developed countries. The main difference of wenluo greenhouse is the covering material: one is glass, the other is solar panels. Of course, there are also some cases of using film mulch, but the cost performance is not as good as even a building arch, so the number of construction is less, so I won't introduce it here. Glass greenhouse Applicable: it is used in greenhouse such as three-dimensional cultivation, scientific research and seedling breeding, ecological restaurant, leisure and sightseeing. Specification: the span of wenluo greenhouse is generally 9.6-12 meters, and the space is about 4 meters. There are also improved structure with 16 meters span and 8 meters, but the greenhouse cost is higher. Basic configuration should include: the wet curtain cooling fan, will open a window ventilated, side turn window shade in ventilation, external shading, thermal insulation, thermal insulation system, etc., according to the need to increase such as mobile seedbed, mobile sprinkler irrigation, three-dimensional cultivation, water system and photovoltaic system, intelligence control system configuration, system generally USES all electric control, high degree of automation. Advantages: beautiful appearance, high greenhouse class; Whole steel frame structure, advanced design, strong resistance to snowstorm, service life up to 25 years; The operating space inside the greenhouse is large and can be built in large areas, which is suitable for factory and large-scale production. Greenhouse automation degree is higher, can expand choice space is bigger. Disadvantages: greenhouse cost is high, investment cost is high; Thermal insulation facilities should be added in winter; Glass, as a fragile object, has safety risks in the process of use. Sunlight board and greenhouse Application: compared with glass connected greenhouse, the main difference lies in relatively low cost of covering material and skeleton. It is also suitable for use in greenhouse such as three-dimensional cultivation, scientific research and seedling breeding, ecological restaurant, leisure and sightseeing. Specification: the structure of sunlight board connected greenhouse and glass connected greenhouse is basically the same, both belong to intelligent connected greenhouse, the difference only lies in the different strength of covering material and skeleton load. Advantages: compared with glass connected greenhouse, the cost is lower; The sunlight board is lighter in quality and has higher safety. Better heat insulation of solar panels; The whole steel frame structure is strong and durable, with long service life. Disadvantages: sunlight board light transmission efficiency decreases with use time; The solar panels need to be replaced after aging. Winter insulation needs to be added.
