Intelligent greenhouses are integrated environmental control systems for facility agriculture. They can directly regulate various factors such as indoor temperature, light, water, fertilizer, and air to achieve high and stable yields of high-quality vegetables and flowers throughout the year, resulting in good economic benefits. Their supporting systems mainly consist of the following three types:
01 Shading System
Generally, there are external and internal shading systems. The shading system is an indispensable part of an intelligent greenhouse and can be flexibly designed according to different regions, crops, and structures. Typically, the shading effect inside the greenhouse depends on the ability of the shading net to reflect sunlight. Different materials used for the shading net often result in significantly different effects. Due to technological advancements, these systems have gradually upgraded. Both indoor and outdoor shading systems have different functions, and using them simultaneously can achieve synergistic effects. Indoor shading systems offer multiple functions such as shading, cooling, heat preservation and energy saving, and condensation prevention, while outdoor shading systems have the characteristics of having no impact on indoor air quality and providing excellent shading effects. Users can choose according to their own needs.
02 Ventilation System
This system is mainly used for cooling greenhouses. Natural ventilation is primarily achieved through windows on the top of the greenhouse, as hot air rises, making top-mounted windows ideal. Windows can also be placed on the sides, and combined with evaporative cooling pads, they can achieve rapid cooling. Greenhouse ventilation mainly relies on making full use of natural conditions. Therefore, before building a greenhouse, users should understand the local natural conditions, including the average annual wind direction. Designing the windows based on these natural conditions is highly valuable.
03 Computerized Intelligent Control System
The greenhouse automated control system is an automatic environmental control system specifically developed and produced for agricultural greenhouses, agricultural environmental control, and meteorological observation. This system includes monitoring ambient temperature, humidity, indoor light intensity, and soil temperature. By acquiring these parameters in real time within the greenhouse and comparing them, it adjusts the greenhouse's supporting systems to ensure plants grow within their optimal growth range, increasing yield. It is the core of the greenhouse system. It can measure agricultural environmental factors such as wind direction, wind speed, humidity, light intensity, air pressure, rainfall, solar radiation, solar ultraviolet radiation, and soil temperature and humidity. Based on the growth requirements of greenhouse plants, it can automatically control environmental control equipment such as window opening, film rolling, fan and wet curtain, biological supplemental lighting, irrigation and fertilization, and automatically regulate the indoor environment of the greenhouse to achieve a suitable range for plant growth and provide the best environment for plant growth.
