1. Smart greenhouse structure difference
The main types of smart greenhouses are solar panel multi-span greenhouses and glass multi-span greenhouses. In comparison between the two, the price of glass multi-span greenhouses is higher than that of solar panel multi-span greenhouses, which mainly depends on their materials. The skeleton of the glass multi-span greenhouse is larger than the skeleton of the sun panel, which is quite different in practice. Especially the main column, this depends on the overall supporting force of the greenhouse. The weight of a square meter of glass is much larger than that of a solar panel. The weight of a square meter of solar panel is very light, so glass is different.
2. Smart greenhouse material difference
In the whole construction process, the difference in the assembly of the skeleton is not big. In the installation of the main covering materials and the installation of the glass, first of all the weight of the glass is relatively large, which is basically difficult for one person to operate, especially the installation of the glass on the top requires mechanical equipment. Of cooperation. The installation of the sun board is not necessary, the weight is relatively light, and it is not fragile. Therefore, in terms of the difficulty of the entire greenhouse materials and construction, the price of the glass greenhouse is about 100 yuan/square meter higher than that of the solar panel greenhouse.
3. The main body of the intelligent greenhouse is reflected in those convenient
Basic configuration of smart greenhouse
For ordinary people, everyone has been talking about smart greenhouses, but in fact, few people really understand smart greenhouses. In the eyes of ordinary people, a smart greenhouse is a multi-span greenhouse, and a solar greenhouse is called a vegetable greenhouse, which is simply defined. In fact, this is not the case. The current definition of a smart greenhouse is the use of various sensors in the greenhouse to monitor the planting environment in the greenhouse, and then we use these data to configure equipment that can change the planting conditions through the greenhouse, such as fan wet curtains, external shading, and supplement light. Lights and other equipment, the temperature of the greenhouse is too high, I can use these data to automatically or manually start the fan, wet curtain, external shading and other equipment to cool the greenhouse until it reaches the temperature suitable for growth.
4. Smart greenhouse sensor
The entry of agricultural Internet of Things into smart greenhouses is a new trend in greenhouse production. Although the current agricultural Internet of Things system is simply the monitoring and statistics of greenhouse data, it is also a simple control of the equipment in the greenhouse. The irrigation system in the greenhouse is also determined by the humidity of the soil, which has been very easy to achieve. I believe that early warning of plant diseases and insect pests in the greenhouse will be realized in the near future, and the traceability function of product growth can be traced back to each agricultural product, from seedling raising to mature picking.
5. Smart greenhouse planting costs and profits
In actual places, smart greenhouses are mainly used for growing seedlings. In my country's vegetable production areas, the main greenhouse is the sunlight greenhouse, which is the main force in vegetable production. For smart greenhouses, the main applications are in agricultural demonstration parks and scientific research units. In the greenhouse nursery, its profit is still very considerable, which is what we call the nursery factory.
In short, the development trend of smart greenhouses in my country is still relatively good, and the reason for hindering development is the price of smart greenhouses. If ordinary vegetables are planted, the cost of construction may not be recovered in 10 years, so ordinary vegetable farmers or vegetable growers will basically not choose to build such a smart greenhouse.
