Multi-span glass greenhouse construction
The design of the multi-span greenhouse incorporates a new type of water-saving facility that eliminates the need for watering, even in hot seasons. According to experts, this kind of greenhouse is characterized by the use of large-scale spraying, drip irrigation and other technologies. It not only keeps the traditional greenhouse from being deformed or falling off, but also ensures that the vegetables grow fast under high temperature. In terms of fertilization, a new fertilization technology with low toxicity and no pollution has been adopted. The service life of multi-span greenhouses is longer than that of traditional sheds. The management method is to take thermal insulation measures before management. This kind of greenhouse management method mainly adopts some simple thermal insulation measures in the greenhouse, such as erecting the scaffolding in a dark, humid and poorly ventilated place. The management method is to lay a layer of plastic film with a thickness of 5cm on the scaffold. Since the plastic film generates heat after contacting with the air, the scaffolding produces thermal expansion, thereby forming a greenhouse.
Multi-span greenhouses also play a vital role in keeping vegetables growing in winter by utilizing facilities such as artificial ventilation and electricity. The design and construction of the multi-span greenhouse adopts the greenhouse in the form of multi-span. The greenhouse is mm higher than the traditional greenhouse. The greenhouse has good ventilation conditions, which is warm in winter and cool in summer. After the multi-span greenhouse is completed, natural factors such as space and terrain can be used for planting. These facilities can provide farmers with certain economic benefits. At the same time, the management of multi-span greenhouses is more scientific and standardized, and the temperature used is also higher than that of traditional greenhouses. The multi-span greenhouse can take different management methods and technical measures according to the needs, which effectively reduces the cost. The planting mode of the multi-span greenhouse is to set up a small cold storage in the greenhouse. The small cold storage is mainly to provide various biomass and trace elements needed in the greenhouse. Multi-span greenhouses occupy an important position in my country's agriculture.
Its advantages are that, on the one hand, the area of the greenhouse is greatly increased without manual operation; on the other hand, since there are many plants in the greenhouse, it can be planted and cultivated in the air. The multi-span greenhouse can not only make the growth faster and better in the greenhouse, but also make the original house built separately into intensive production and standardized management. This has created a very good condition for the development of modern agriculture in our country. The multi-span greenhouse is an ecological greenhouse with low consumption and low emission, which can not only ensure temperature stability, but also reduce the erosion of temperature on soil. This kind of eco-friendly new building materials is the first time in China. The architectural form and design style of the multi-span greenhouse all reflect the modern people's pursuit of a natural and environmentally friendly lifestyle. There is a kind of super large greenhouse, and here you can see that each room in the greenhouse has a large thermostat that can monitor the indoor air pressure and humidity in real time.
At the same time, the multi-span greenhouse also has good fire prevention, sound insulation and other functions. At the same time, the height of the space used has been greatly improved compared with the traditional greenhouse. Therefore, the multi-span greenhouse is especially suitable for warm in winter and cool in summer. The characteristics of the multi-span greenhouse are used in the environment of warm winter and cool summer; used in the environment of hot summer and cold winter; used in spring and autumn. The height of the multi-span greenhouse is much larger than that of the traditional greenhouse. For example, in the process of greenhouse construction, the following methods are used. The first one is to set up an electronic monitoring system inside the greenhouse. The electronic monitoring system can monitor the whole process of various conditions in the greenhouse, and implement effective management according to the characteristics of the greenhouse and its ecological environment. The second is to use a dedicated greenhouse management program. For example, in the process of greenhouse construction, specific management methods are formulated according to different management measures. The fifth is to use a variety of technical means. The sixth is to set up special greenhouse management personnel.
