The working principle of greenhouse is mainly based on the radiation, absorption, conduction and storage of solar energy.
The structural design of greenhouses usually includes roofs, walls, windows and other parts, which play different roles in storing heat.
As a building structure that uses solar energy to store heat and regulate temperature, greenhouses play an important role in agricultural production and scientific research.
In order to reduce humidity and replenish sufficient carbon dioxide concentration, excess heat must be released to cool and discharge excess water.
The solar greenhouse generally uses a water recycling system consisting of an endothermic treatment and a water circulation system.
The greenhouse was first invented in the Han Dynasty**. According to the "Book of Han·Biography of Zhao Xinchen", the Han Dynasty official Zhao Xinchen once reported to Emperor Yuan of Han.
Determine reasonable structural parameters. According to climatic conditions and production requirements, choose appropriate structural forms to ensure that the structure is safe and applicable.
Single-slope greenhouse: This type of greenhouse is oriented north-south and generally adopts a single-slope design. The lighting surface is arranged in an east-west direction, and the lighting is uni
In the past two years, in order to expand the urban greening area, the call for rooftop greening is gradually increasing.
CO2 and O2 are the raw materials for photosynthesis and respiration of plants, respectively. CO2 is the "carbon source" for crops to carry out normal physiological activities.
In today's urban soil situation, there is generally no soil for plant cultivation in most cases in home greenhouses.
Water is the basic condition for the life activities of crops. All life activities of crops are carried out with the participation of water, such as photosynthesis, respiration and transpiration of cr
