Smart Greenhouse
Smart Greenhouse is a kind of modern agricultural facilities, which combines advanced technical means to achieve precise control and management of crop growth environment.
The temperature, humidity, light intensity, soil temperature and water content in greenhouse play a key role in the growth of crops in greenhouse. With PLC as its core, the automatic control system of greenhouse adopts the computer distributed network control structure to automatically adjust and detect the air temperature, soil temperature, relative humidity, CO2 concentration, soil moisture, light intensity, water flow, PH value, EC value and other parameters in the greenhouse in real time, so as to create the best environment for plant growth. The environment in the greenhouse is close to the ideal value of artificial imagination, so as to meet the needs of the growth and development of greenhouse crops. |

The main purpose of Film greenhouse ventilation is to remove the waste heat and moisture in the greenhouse, adjust the air composition in the greenhouse, remove harmful gases, and make the environmental temperature, humidity and air conditions in the greenhouse suitable for plant growth.
- Natural ventilation
Film greenhouse relies on natural ventilation to regulate the indoor environment most of the time. The structural form of large productive Film greenhouse is generally double-slope multi-span greenhouse, and the ventilation form is to set ventilation windows on the side wall and roof ridge. Its total ventilation area is not less than 15% of the greenhouse area, preferably more than 30%. When the roof wind window is opened, the window sash should be inclined upward beyond the horizontal plane. When it is fully opened, it forms an angle of 100 with the horizontal plane, which can achieve good ventilation effect.

2.Forced ventilation
Film greenhouses rely on natural ventilation to regulate the environment most of the time, when the temperature is high in summer, especially when the outdoor temperature is over 33 ºC, it is difficult to meet the cooling requirements of greenhouses by natural ventilation alone, so forced ventilation and other measures are commonly used in production. Forced ventilation is to use fans to convert electric energy or other mechanical energy into wind energy, forcing air flow to ventilate the greenhouse and achieve cooling effect.

The environment in the greenhouse is close to the ideal value of artificial imagination, so as to meet the needs of the growth and development of greenhouse crops. It is suitable for seedling breeding, high-yield planting, precious and rare flower cultivation and other sites to increase the output of greenhouse products and improve labor productivity.
Smart Greenhouse is a kind of modern agricultural facilities, which combines advanced technical means to achieve precise control and management of crop growth environment.
The characteristics and advantages of intelligent greenhouse are mainly reflected in the following aspects:
1. Environmental control: The intelligent greenhouse is equipped with an integrated environmental control system, which can automatically adjust the indoor temperature, light, moisture, fertilizer, gas and other factors. This meticulous management contributes to the high yield and stable growth of crops throughout the year.
2. Technology integration: Intelligent greenhouses usually adopt industrial integrated design, integrating water supply system, temperature control system, auxiliary lighting system, humidity control system and other subsystems to achieve all-round control of crop growth conditions. |
|
3. Automatic operation: Based on the results of data analysis, the intelligent greenhouse can automatically perform operations such as irrigation, fertilization, adjustment of sunshade nets, opening and closing skylights, etc. To ensure the best growth conditions for plants.
4. Save resources: The efficient management of intelligent greenhouses helps to reduce the waste of resources, such as the use of water and fertilizer through precise irrigation and fertilization.
|
5. Economic benefits: Because the intelligent greenhouse can provide a more stable growth environment, it can improve the yield and quality of crops, thus bringing better economic benefits.
6. Movable structures: Some smart greenhouse designs include movable skylights and other structures to accommodate changes in weather conditions and crop demand.
7. Application of Internet of Things: Intelligent greenhouses usually use agricultural Internet of Things technology to connect the environmental monitoring system of greenhouses with other devices through the network to achieve remote monitoring and management.
8. Environmental protection and energy saving: The design of intelligent greenhouse also pays attention to environmental protection and energy saving, such as the use of renewable energy and efficient insulation materials to reduce energy consumption. |
Generally speaking, Smart Greenhouse represents the development direction of modern agriculture. It not only improves the efficiency and quality of agricultural production, but also provides technical support for the sustainable development of agriculture. With the continuous progress of technology, the application of intelligent greenhouse will be more extensive in the future, and the impact on agricultural production will be more far-reaching.
1.Hot water heating The hot water heating system is composed of three basic parts: hot water boiler, heat supply pipe and heat dissipation equipment.
Its working process is to heat water with the boiler and then pressurize it with the water pump. The hot water is supplied to the radiator in the greenhouse through the heat supply pipe. The radiator is used to heat and raise the temperature of the greenhouse. The cooled hot water is returned to the boiler for reheating and repeated circulation. The hot water heating system is stable and reliable, which is the most commonly used heating mode in Film greenhouse. |

2.hot air heat system
Consists of a heat source, an air heat exchange, a fan and an air supply pipeline. Its working process is as follows: the air exchanger is heated by the heat provided by the heat source, and the fan is used to force part of the air in the greenhouse to flow through the air heat exchanger, so that the greenhouse is heated by continuous circulation. The heat source of the hot air heating system can be oil, gas, coal-fired devices or electric heaters, and can also be hot water or steam. The installation forms of hot air heating equipment are different for different heat sources. |

3.Electric Heating
The more common way of electric heating is to bury the ground heating wire underground |
1. Shading and cooling methods include indoor shading and outdoor shading. The indoor shading system is a supporting system made of metal wires or plastic mesh wires connected to the greenhouse framework, and the shading net is installed on the Film supporting line. Generally, electric control or manual control is adopted. The outdoor shading system is characterized in that a shading framework is additionally arranged outside the greenhouse framework, a shading net is arranged on the framework, and the shading net can be driven by a curtain pulling mechanism or a Film rolling mechanism to be freely opened and closed. The outdoor installation of the sunshade net has good cooling effect, can directly block the solar energy outside the greenhouse, and various types of sunshade nets can be used.
2. Evaporative cooling uses the unsaturation of air and the latent heat of evaporation of water to cool down. When the moisture in the air is not saturated, the moisture will evaporate into water vapor and enter the air. When the water evaporates, it absorbs the heat in the air, reduces the temperature of the air and increases the humidity of the air. In the process of evaporative cooling, it is necessary to ensure the air flow inside and outside the greenhouse, to discharge the high temperature and humidity gases from the greenhouse, and to supplement fresh air, so the forced ventilation method must be adopted. Evaporative cooling methods include wet curtain-fan cooling and spray cooling.
3. The roof spray cooling system is to spray water evenly on the roof of the Film greenhouse to reduce the temperature of the greenhouse. When water flows on the Film greenhouse roof, the water exchanges heat with the Film of the greenhouse roof and takes away the heat in the greenhouse. In addition, when the thickness of the water Film is greater than 0.2 mm, all the energy of solar radiation is absorbed and taken away by the water Film, which is equivalent to shading.
