What should be paid attention to in plant lighting

2021-08-05

Plants don't speak, so we need to get answers through scientific methods to study the different needs of plants for light.
 
 
 
There are two kinds of plant factories involved in plant lighting: greenhouse planting with the combination of sunlight and fill light and planting in a completely artificial environment.
 
 
For the greenhouse planting and hybrid plant factory adopting the combination of sunlight and fill light, the accurate method is to do the spectral analysis of the radiation field of natural light to determine the amount of fill light. For the site without conditions for spectral analysis, you can test the average value of the illumination value, divide the average value of the illumination by 55, and then you can get the PPFD value of the planting surface under the sun light This simple method is very useful for project planning and cost accounting. Hybrid greenhouse can reduce or not use green light band. Whether green light supplement is needed needs to be determined by testing the green light radiation of direct sunlight and scattered light.
 
 
 
In the fully artificial environment, although the red and blue band light has obvious effect on the cultivation of leafy vegetables, the taste of hydroponic vegetables is still the key to improve the quality of vegetables. We suggest that the white light and red light spectrum should be used. The spectrum design in the fully artificial environment should take the control of carbon dioxide concentration, ventilation, environmental temperature, substrate or nutrient solution into consideration, In order to increase the number of planting layers and reduce the height of nutrient tank as much as possible, this method will reduce the balance of nutrient solution and affect the absorption efficiency of spectrum. The important goal of spectrum design in a completely artificial environment is to control the quality of planting, but the planting of plant growth process is not competitive in the market.
 
 
 
When it comes to plant lighting, it's just a matter of adding a light bulb. The development of plant lighting in foreign countries has been quite perfect. With the improvement of people's life quality, it is the general trend to let plant planting into the family, and plant lighting will also usher in the upsurge of development.
