Greenhouse

Technical Field

The utility model belongs to farming facility field relates to a warmhouse booth.

Background

Factors influencing the growth of plants include temperature, illumination, humidity, nutrient elements and the like, and in traditional agricultural production, the temperature, illumination and air humidity of the plants completely depend on natural climatic conditions. The reaction curve of the plant growth speed along with the temperature is actually the reaction curve of the enzyme and the temperature, the plant body is a container for chemical reaction, and the reaction speed depends on the activity of the enzyme. Within a certain temperature range, the activity of the enzyme is positively correlated with the temperature, in a linear relationship, until an optimum temperature is reached, above which the activity of the enzyme is reduced and the growth of the plant is thus influenced. The plant growth reference temperature is the lowest temperature at which the plant performs photosynthesis, below which the plant stops growing. Too low or too high a temperature can cause the plant to stop growing. The optimal temperature for plant growth is the temperature at which the plant photosynthesis rate is highest, and decreases with plant maturity. The temperature required by different plants is different, the temperature required by the plants living in the tropical zone is higher, and the most suitable temperature is about 25-37 ℃; the most suitable temperature for the growth of the cold-zone plants is about 11-23 ℃. The temperature requirements of plants living in temperate zones are different between plants living in winter and plants living in summer. Plants grow fastest under optimal temperature conditions, but this is not the temperature at which plants grow most robustly. At the optimum temperature, the organic matter in the plant is consumed too much, and the plant grows slender and weak. Therefore, in production practice, robust plants are usually required to be cultivated at a temperature lower than the optimum temperature, which is called the coordinated optimum temperature. Experiments show that the vegetative growth of plants is best in the cyclic variation of higher temperature in the day and lower temperature at night.

In order to realize the cultivation of vegetables in advance, simple greenhouse cultivation technology is widely used in southern areas.
