Is it really useful to use LED plant fill lights for greenhouse cultivation?
Customers often ask us, is it really useful to use LED plant fill lights for greenhouse cultivation? In fact, this question can be answered in the following two ways.
1. Growth characteristics of greenhouse plants:
The spectrum required for general plant growth is in the range of 288-800nm. The red light (peak value 660nm), which is mainly divided into the blue light band of 400-450nm and 600-800nm, has the greatest contribution to the photosynthesis of plants. The red light and blue light in the spectrum of LED plant fill light can fully meet the light required in the growth process of quality plants. Therefore, LED plant fill light technology will be the new trend and development direction of modern smart agriculture (technical agriculture) and urban agriculture.
The value of the abscissa represents the wavelength band. It is obvious that this spectrogram highlights two wavelength bands of blue light and red light. The blue light part is 400-500NM and the red light part is 600-800NM.
Comparison of the characteristics of traditional plant fill light and LED plant fill light:
The traditional shortcomings are that the light quality in the spectral components is not pure, the light intensity is inconsistent, and the energy efficiency of the light source is low. However, the LED plant fill light has the characteristics of pure spectrum, high light efficiency, energy saving and environmental protection, so it is widely used in the facility cultivation environment. be utilized.
In terms of the supplementary light effect, the LED plant supplementary light technology is probably used, which can significantly promote the development of spinach, radish and lettuce, improve the morphological indicators, and increase the growth rate and photosynthetic rate by more than 20%. It maximizes betalain bioaccumulation in sugar beet and produces the highest accumulation of sugar and starch in hairy roots. It can significantly change the shape of stems and leaves of pepper and perilla, and increase the photosynthetic rate of plants. When used on flowers, it can increase the number of flower buds and flowering, improve the quality of flowers and prolong the flowering period. It can cause an increase in the number of stomata in marigold and sage plants, and the increase in stomata means an increase in photosynthesis.
