Knowledge and Cost Reference of Glass Greenhouse

A glass greenhouse is a type of greenhouse with glass as the main light-transmitting covering material. As an important type of greenhouse, it has significant characteristics such as excellent lighting, strong sealing, and ease of mechanized operation and management. Its service life is among the top in various cultivation facilities, and it can adapt to a variety of regions and climatic conditions, making it a durable and preferred facility in agricultural production.

Structure and Classification of Glass Greenhouses

A glass greenhouse is composed of a main structure and a foundation structure. In the industry, different construction models are usually divided according to the size of the span and bay; according to the use function, it can be divided into vegetable glass greenhouses, flower glass greenhouses, seedling glass greenhouses, ecological glass greenhouses, scientific research glass greenhouses, special-shaped glass greenhouses, leisure glass greenhouses and other categories.

The area and usage mode of the glass greenhouse can be flexibly designed according to the needs of the owner, with the smallest being the courtyard leisure type; large-scale high-tech intelligent glass greenhouses represented by Dutch glass greenhouses can have a height of more than 8 meters, a span of 12 meters, and a maximum bay of 8 meters. The internal space is spacious, and the comprehensive utilization rate is extremely high.

Intelligence and Advantages of Glass Greenhouses

With the advancement of science and technology, the intelligence level of glass greenhouses has been continuously improved, equipped with a comprehensive environmental control system. With this system, it is possible to directly adjust various factors such as temperature, light, water, fertilizer, and gas in the greenhouse, so as to realize the annual high-yield and stable production of vegetables, flowers and other crops, with significant economic benefits.

Intelligent greenhouses have injected strong impetus into agricultural development. Their control systems generally consist of three parts: a signal acquisition system, a central computer, and a control system. They can realize one-key control of the greenhouse's climate environment and irrigation and fertilization, which greatly improves management efficiency.

In addition, glass greenhouses also have excellent energy-saving and heat-insulating effects. It uses a new type of composite material made of double-slope reflective curtain wall profiles as the external sunshade system, which can effectively block direct sunlight from entering the internal shade space in summer, reducing the indoor temperature by 3-5°C every day; at the same time, large arched roofs and outer window frames made of high-quality aluminum-magnesium alloy plates have good heat reflection functions, which greatly reduce heat loss and achieve the purpose of energy saving. To sum up, glass greenhouses are an efficient, energy-saving and environmentally friendly agricultural facility, providing a solid support for modern agricultural production.

Cost of Glass Greenhouses

The cost of a glass greenhouse is affected by many factors such as region, materials, and equipment, and varies greatly. The common cost range is 400 yuan to 600 yuan per square meter. Based on this estimate, the cost of a glass greenhouse for one mu of land (about 667 square meters) is roughly between 260,000 yuan and 400,000 yuan.

It should be noted that the above is only a rough estimate. The specific cost needs to be detailed designed and quoted according to the actual situation and specific requirements. At the same time, when making investment decisions, it is also necessary to comprehensively consider factors such as the construction period, service life, and maintenance costs of the greenhouse to make a comprehensive and reasonable plan.

Main Configurations of Glass Greenhouses

The core configurations of a glass greenhouse mainly include the following systems:

· Frame structure system: Usually made of hot-dip galvanized or aluminum-zinc plated steel, which has good corrosion resistance and sufficient strength, supports the overall structure of the greenhouse, and ensures the stability and durability of the greenhouse.

· Covering material system: Glass is the main covering material, and transparent glass is generally used to ensure that sunlight can fully enter the greenhouse, providing the necessary light conditions for plant growth.

· Ventilation system: It is used to maintain air circulation and temperature control inside the greenhouse. It can be realized by natural ventilation or mechanical ventilation, and the ventilation volume can be adjusted according to the temperature difference and humidity difference inside and outside the greenhouse.

· Sunshade system: Its main function is to reduce the light intensity and temperature inside the greenhouse. There are two ways: external sunshade and internal sunshade. The indoor light conditions can be controlled by adjusting the opening and closing of the sunshade curtain.

· Electronic control system: The various systems of the greenhouse are switched on and off through the electric control cabinet, realizing the electrified management of the greenhouse and improving the convenience of operation.

· Wet curtain and fan cooling system: This is a commonly used cooling equipment in greenhouses. It uses the water circulation system installed on both sides of the greenhouse to make the air blown by the fan pass through the water in the wet curtain, and achieve the cooling effect through water (heat absorption).
