The best fill light for greenhouse plants LED grow light!
When planting crops in greenhouses, the most worrying about the lack of light for plants. Generally, in winter, or in the north, there will be insufficient sunlight, which will affect the growth, flowering and fruiting of greenhouse crops. Therefore, it is necessary to use plant supplement light to supplement light for plants.
Plant supplement light commonly used in greenhouses mainly include incandescent lamps, fluorescent lamps, high pressure sodium lamps, metal halide lamps, and LED grow lights. Which plant supplement light has the best effect on greenhouse plants? Let’s take a look!
The disadvantages of high-pressure sodium lamps, fluorescent lamps, metal halide lamps, and incandescent lamps are high energy consumption, high operating costs, and high energy costs, which account for a high total cost. LED grow lamps have higher luminous efficiency and consume less power. Energy saving and environmental protection, spectrum Abundant, to give plants better growth, long service life and other advantages, so the greenhouse plant supplement light LED grow light must be the best choice.
LED grow lights are specially developed for plants to supplement light. Its spectrum is in line with the absorption of sunlight by plant growth, and different powers can meet the requirements of crop growth for light intensity. The light source of LED grow light is mainly composed of red and blue light sources, and the main influences on plants are: blue light wavelengths 450-460nm and 460-470nm, red light wavelengths 620-630nm and 640-660nm. Red light can promote the metabolism of stems, and greatly promote the flowering and fruiting of plants. Blue light mainly prevents plants from growing, promotes the formation of plant dry matter, and has a significant effect on the growth of rhizomes.
LED grow lights provide a reasonable light environment for greenhouse plants, promote the growth and development of plants, and have certain requirements for light quality and intensity. LED grow light is an artificial light source used in the photosynthesis growth system of plants to meet the light conditions of photosynthesis. Yaorong's fifth generation plant lamp! In the lack of sunlight, this kind of lamp can play the role of sunlight, so that plants can grow and develop normally or better.
Use LED grow lights to fill light in the greenhouse, but you need to pay attention to:
1. The roof of greenhouses is cleaned regularly to clean the "roof garbage", otherwise the transparency is not enough, it will have a great impact on the light and temperature in the shed, and then affect the photosynthesis and respiration of plants.
2. At the same time, reflective measures can be taken in the greenhouse to improve the effective utilization of LED grow lights. Use reflective materials when setting up the frame, keep the middle bracket upright, and slightly tilt the north and south brackets, which can increase the light utilization rate. 5- -10%, reused by plants.
Use LED grow lights to better supplement light for plants, full-spectrum or customized red and blue ratios to meet all the spectra of plant growth stages, which can effectively shorten the plant growth cycle.
