The ordinary LED lamp can replace the plant fill light lamp, but the effect is far worse than the plant fill light lamp.
The light of the wavelength of the plant light supplement lamp is conducive to plant growth, and the full spectrum lamp has ultraviolet and far-infrared spectrum, which is conducive to improving the sugar content of the plant and improving the taste. Greenhouse is widely used to produce anti season flowers, fruits, vegetables, etc. due to the short sunshine time in winter and spring, slow growth of crops and low yield, it is urgent to supplement light. Most of northern China is located in the east of Asia, which belongs to the temperate monsoon climate. In winter and spring, influenced by the cold air of Siberia, sometimes rain and snow are formed due to the convergence of cold and warm air. There were 1-3 days of low temperature and 7-8 days of continuous overcast.
In the spectrum of plant light supplement lamp, there is almost no ultraviolet light, but the ultraviolet light plays a role in improving the brightness of flowers. The reason why the flowers in plateau area are particularly bright is that they have rich ultraviolet radiation.
In addition, UV light can promote the synthesis of sugar and improve the sugar content of plants, especially berries.
Eggplant fruits and melon vegetables have certain requirements for light time and intensity. If the light time of watermelon is less than 11 hours, all young fruits will fall off. Vegetables with moderate light intensity, such as peas, beans, celery, radish, onion, etc. The light intensity of lettuce, spinach, chrysanthemum, ginger and other vegetables with weak light intensity is lower.
