A light source suitable for plant growth

How to use LED semiconductor bulb to configure the most suitable light source for plant growth



The proportionate coloured lights can make strawberries and tomatoes more sweet and nutritious. Using light to irradiate Holly seedlings is to mimic the photosynthesis of plants outside. Photosynthesis refers to the process that green plants use the chloroplasts to convert carbon dioxide and water into organic substances stored in energy and release oxygen through the chloroplasts. Sunlight is made up of different colors of light. Different colors of light play different roles in plant growth.

LED light source is also called semiconductor light source, which has a relatively narrow wavelength and can control the color of light. Using it to irradiate plants individually can improve plant varieties.

The seedlings of holly grown in purple light are the tallest, but the leaves are small and shallow, with a malnutrition. The seedlings under the yellow light are not only dwarf, but also the leaves are lifeless. The growth of holly under red and blue light is best, not only strong, but also highly developed. The red light bulb and blue light bulb of the LED light source are arranged in proportion to 9:1.

The results showed that the red and blue light of 9:1 was the most favorable for plant growth. After this light source, the fruit of strawberry and tomato was full, the content of sugar and vitamin C increased obviously, and there was no hollow phenomenon. Daily exposure to 12— for 16 hours, strawberries and tomatoes grown under such a light source will be more delicious than ordinary greenhouses.
