Description

An LED light control system for greenhouse seedling cultivation

Technical Field

The utility model belongs to the technical field of modern LED light control, and in particular relates to an LED light control system for greenhouse seedling cultivation.

Background Art

Seedling cultivation is an important part of agricultural production and is very critical. The quality of seedlings has an important impact on its later yield and quality. However, seedling growth is easily affected by environmental factors such as light, temperature, and humidity. Especially in the winter and spring seasons in northern my country, low temperatures often occur due to rain, snow, haze and other weather conditions, which also cause insufficient light intensity and hours. In the winter and spring seasons in the north, the greenhouse has short sunshine time and very low external extreme temperatures. There must be external covering insulation equipment outside the greenhouse. In order to achieve the purpose of greenhouse insulation, the quilt can only be opened late and covered early, which further shortens the sunshine time and reduces the accumulation of crop photosynthetic products, which is not conducive to the growth of the seedling process. In winter seedling cultivation, if the light intensity is insufficient, tomato plants are prone to leggy growth and malnutrition, resulting in fewer flowers in the later stage, serious falling flowers and fruits, and an increase in various physiological diseases, which seriously affects the quality of seedlings.

There are two main methods for traditionally controlling the brightness of LED lamps: one is to change the current flowing through the LED lamp; the other is to change the length of time the LED lamp is powered on. Both methods have some disadvantages and limitations. For example, changing the current will affect the color temperature and stability of the LED lamp; changing the length of time the LED lamp is powered on will cause flickering and frequency interference. In addition, both methods require additional hardware components or complex software programs to achieve the adjustment function, and it is difficult to achieve high precision and high response speed. Most of the supplementary light sources are fixed, and the growth height and light requirements of different plants are different, which requires staff to replace the light source or adjust the height of the light source. This method not only has large errors, is time-consuming and labor-intensive, but also wastes energy and even affects the growth of plants.
