Introduction to the main systems of greenhouses and their functions and uses

The so-called modern greenhouse is based on the traditional greenhouse and adds some temperature, light and humidity that can control the growth parameters of plants to achieve the best environment for plant growth, so that the plants can achieve the highest yield. Today, I will introduce the common systems of multi-span greenhouses.

The heating system in the greenhouse is to select appropriate heating equipment to meet the heating load requirements of the greenhouse. It is generally composed of heat source, indoor heat dissipation equipment and heat medium delivery system. Related equipment includes: boiler, delivery pipeline, circulating water, radiator and various control and regulating valves.

The function of the greenhouse irrigation system is mainly to extract irrigation water from the water source, and after appropriate pressurization, purification, filtration and other treatments, it is sent to the field irrigation equipment through the water pipeline, and finally the irrigation device in the greenhouse field irrigation equipment irrigates the crops. A complete set of greenhouse irrigation system usually includes five parts: water source project, head hub, water supply network, field irrigation equipment, automatic control equipment, etc. In actual production, due to different water supply conditions and irrigation requirements, the greenhouse irrigation system may only consist of some equipment. The irrigation system used in the greenhouse is classified according to the form of the sprinkler used, mainly divided into pipeline irrigation system, drip irrigation system, micro-sprinkler irrigation system, micro-sprinkler belt micro-irrigation system, infiltration irrigation system, walking sprinkler irrigation system

The greenhouse control system is based on the information collected or observed by the temperature and humidity sensors, light sensors, CO2 sensors, outdoor weather stations, etc. installed inside and outside the greenhouse, and controls the drive/actuator (such as fan system, window opening system, irrigation and fertilization system, etc.) through control equipment (such as control box, controller, computer, etc.), and regulates and controls the environmental climate (such as temperature, humidity, light, CO2, etc.) and irrigation and fertilization in the greenhouse to meet the growth and development needs of cultivated crops. Greenhouse control systems can be divided into manual control systems and automatic control systems according to the control method. Greenhouse automatic control systems are divided into digital controller control systems, controller control systems and computer control systems.
