Irrigation systems in greenhouses
Irrigation systems in greenhouses are critical to ensuring the water needed to grow crops. According to different needs and technological developments, greenhouse irrigation systems can be divided into many types, each system has its own unique advantages and disadvantages.
This system has the advantage of lower cost, but the disadvantage is that it can lead to waste of water because it depends on manual operation and environmental conditions.
Drip irrigation systems: Drip irrigation reduces evaporation and overwatering problems by delivering water directly to the soil near the roots of the crop. Drip irrigation system not only saves water resources, but also reduces labor input, which is an efficient irrigation method.
Sprinkler irrigation system: The sprinkler disperses the water and fertilizer solution in the air in a mist form, and then falls on the surface of the crops and soil. This system has the advantage of lower equipment investment costs and lower water quality requirements, but its disadvantage is that it may increase humidity in the greenhouse, which may not be suitable for some crops.
Micro-irrigation systems: Micro-irrigation is a local irrigation technique that wets the soil near the roots of crops with a tiny flow. This system can effectively control the water supply and reduce water evaporation, while maintaining a low humidity in the greenhouse.
Intelligent irrigation system: The intelligent irrigation system based on the Internet of Things technology uses sensors, wireless networks and other technologies to monitor the environmental parameters in the greenhouse in real time (such as soil moisture, light intensity, etc.), and carries out precise irrigation according to the water requirements of crops. Such systems can significantly improve irrigation efficiency, reduce water waste, and simplify management through remote control.
Integrated water and fertilizer system: The integrated system combining drip irrigation and fertilization functions can automatically irrigate and fertilize according to soil moisture, and further improve the efficiency of water and fertilizer utilization.
Choosing the right greenhouse irrigation system requires consideration of factors such as the specific needs of the crop, the size and layout of the greenhouse, and economic costs. With the advancement of technology, intelligent and automated irrigation systems are increasingly favored because they can provide a more efficient and scientific way of management.
