The significance of thermal radiation to greenhouse plants
作者: 时间: 2024-08-01
Thermal radiation is of great significance to greenhouse plants, mainly in the following aspects:
Provide a suitable temperature environment: Thermal radiation is one of the main sources of heat for greenhouse plants. By controlling the level of thermal radiation in the greenhouse, a suitable temperature environment can be provided for plants to promote their normal growth and development.
Affecting photosynthesis: The visible light part of thermal radiation is necessary for plants to carry out photosynthesis. A suitable level of thermal radiation can increase the photosynthetic rate of plant leaves and improve the efficiency of photosynthesis, thereby increasing the yield and quality of plants.
Regulating plant growth cycle: Changes in thermal radiation levels can affect the growth cycle of plants. For example, in winter or early spring, increasing the level of thermal radiation in the greenhouse can extend the growing season of plants and make them bloom and bear fruit earlier.
Controlling plant transpiration: Changes in thermal radiation levels can affect the transpiration of plants. In a high temperature environment, the transpiration of plants will increase, resulting in increased water loss. By controlling the level of thermal radiation in the greenhouse, the transpiration of plants can be reduced, water consumption can be reduced, and water use efficiency can be improved.
Preventing plant diseases: A suitable level of thermal radiation can inhibit the occurrence of plant diseases. The occurrence of some plant diseases is closely related to temperature. By controlling the level of thermal radiation in the greenhouse, plants can be prevented from being in temperature and humidity conditions suitable for the occurrence of diseases, reducing the occurrence and spread of diseases.
In short, thermal radiation has an important impact on the growth, development, yield and quality of greenhouse plants. By reasonably controlling the level of thermal radiation in the greenhouse, a suitable growth environment can be provided for plants, improving agricultural production efficiency.
