Description

Planting light source control system

Technical field

The present invention relates to the field of light source technology, and more particularly to a planting light source control system.

Plant growth requires photosynthesis, and the light source of photosynthesis of conventionally planted plants is mainly from sunlight. Plant growth alternates periodically and periodically with the sunrise, sunset, and night, and these changes affect the growth rate of plants. The external factors affecting the photosynthesis efficiency of plants are mainly the following: (1) illumination; (2) carbon dioxide; (3) temperature; (4) moisture; (5) mineral nutrition; (6) diurnal changes in photosynthesis. In order to improve the growth efficiency of plants, it can be achieved by scientifically adjusting the above six external factors. At present, the commonly used methods are mulch film covering, greenhouse cultivation, regular watering and fertilization, etc. These conventional methods can only solve the problems of temperature, light, water, nutrition, etc., and cannot fundamentally design a standard stable external growth for plants. surroundings.
