Light is one of the most important environmental factors in plant growth. It not only provides radiant energy for plant photosynthesis, but also provides signal transduction for plants to regulate their developmental processes. The biological law of LED light quality is applied to the field of vegetable planting, group cultivating seedlings and other facility plant production fields. Through the regulation of the light environment, the production cycle is controlled, so as to prevent the plants from growing, promote growth, increase freshness, enhance quality, and stabilize yield effect.
1. Adjust the shape of plant seedlings
Different plants have different needs for light. At different growth stages, plants have different needs for light. In the plant seedling stage, preventing the phenomenon of leggy and stiff seedlings and cultivating strong seedlings at the right age are the basis for high quality and high yield, so pay attention to the time of light during this period. For some flower crops that like sunshine, if it is cloudy weather, you should pay attention to supplementing the light for about 12 hours to ensure that the plant seedlings have sufficient light to promote their internal energy, adjust the shape of the plant seedlings, and prevent the problem of flower bud differentiation and deformed fruit. Therefore, if the light is not enough, artificially use the plant supplementary light to adjust the light to ensure the growth of the seedlings.
2. Realize high quality and high yield of crops
Increase the transmittance of the lighting surface of greenhouse facilities, improve the lighting conditions, and make full use of light energy. This is because light is the energy source for photosynthesis of horticultural plants, and the intensity of light in the greenhouse and the length of time it sees light are the main factors that determine the level of photosynthetic yield. Through light regulation, the maximum use of light energy can not only provide an energy source for the photosynthesis of plants, but also provide an appropriate temperature for the growth of plants. Indoor light intensity is not only affected by seasonal changes, but also affected by factors such as the shape and angle of the light-transmitting surface of the greenhouse, the type and condition of the plastic film, the greenhouse support and the group structure. The light regulation makes the light-receiving area of the crop uniform, and the quality is guaranteed.
3. Realize energy-saving production
The introduction of LED light quality control can save agricultural resources, protect the environment, and reduce pollutant emissions. Integrated application of LED lighting, soilless cultivation, and environmental control. It is also a new growth point for my country’s LED semiconductor lighting industry. This is favored by LED lighting companies, and lighting companies have already set foot in plant lighting, especially in artificial light plant plant plant lighting. By forming a horticultural crop industry system of LED light sets, it is helpful to reduce costs and labor.
Fourth, solve the lack of light caused by various environmental factors
The traditional greenhouse is affected by the weather such as cloudy, rainy and foggy, and the plant is exposed to uneven illumination area. With the help of the intelligent control LED system, it implements real-time and dynamic provision of light signals and photosynthetic energy to the plants. In terms of space, it breaks through the limitation of one-way lighting and realizes multi-directional three-dimensional lighting.
Therefore, at present, through the regulation of light environment, LED light source can be intelligently controlled according to needs, accurately benchmarking the light environment needs of plants at each growth stage, promoting the maximum utilization of light energy by plants, converting them into biomass and quality substances, and greatly improving the quality of crops. grow.
