In the field of plant lighting, as one of the fastest growing agricultural lighting fields in recent years, LED has obvious advantages in plant lighting because of its high luminous efficiency, low heat generation, small size and long life. Plant lighting and other LED lighting With the maturity of technology, companies have moved from the general lighting market to the field of plant lighting, and plant lighting has broad prospects.
So, what problems exist in LED plant lighting in the process of development? What is the current proportion of LEDs in plant lighting? What is the future trend of LED plant lighting compared with other light sources in plant lighting? At the plant lighting conference held a few days ago, the guests discussed this in detail.
1. How to treat the current development of the entire plant lighting industry?
Fang Wei: The future of the plant lighting industry should be very optimistic. From the current sales volume of plant products, whether it is the leaf of the entry or the ingredients of health, it will even become the medicine of the future trend, whether it is domestic or Taiwan. The prices of these products are getting higher and higher, and the future of plant lighting must have a bright future. The premise is that your product must be distinctive.
The product has its own characteristics. The next step in determining whether the industry is successful is to see who can successfully execute the commercial marketing model. The life cycle of plant products is very short, but many people will not sell, and the products cannot be sold. In fact, products need different routes. From fresh vegetables to processed products, from semi-finished products to finished products, when products become diversified, the channels of sales become diversified. Sales naturally go up.
2. At present, LED accounts for the total market share of plant lighting fixtures?
Lun Lun: At present, the plant lighting fixtures used in greenhouses are mainly high-pressure sodium lamps. The domestic products are mainly fluorescent lamps. LED lamps are practically few. In recent years, the growth rate of applications in the cannabis field has accelerated. Some plant factories also have LEDs are used, but in general LEDs currently account for a small percentage.
3. What are the advantages of vegetables grown with plant lighting compared to ordinary vegetables?
Jiang Jingjing: There are several characteristics. The first biggest feature is that the vegetables grown in the plant factory are very safe. Only in a controlled environment, it is illuminated with LED lights, and its environment and nutrient solution are controlled by hand. This is Beyond green vegetables, and do not need to use any pesticides or herbicides in the plant, our nutrient solution avoids heavy metal pollution in traditional soil. The second feature, because we are artificially created shortcuts, the air is filtered, the water is purified, and the dust and bacteria are very low. The third characteristic is that the products of the plant factory are very fresh. Compared with the losses caused by long-distance transportation of other traditional agricultural plants, the plant factory is placed around the big city. It can be completed within 12 hours from the receipt of the table, and the effect of planting vegetables at the door of the house. it's the same.
In addition, compared with traditional agriculture, plant lighting factories can be customized. Traditional agriculture is limited by the fact that climate and temperature change all year round. Although greenhouse greenhouses can now eat anti-season products, plant factories have no concept of season. The products are the same throughout the year and are highly efficient.
Fang Wei: We should have this kind of thinking: the value of the vegetable factory and the ordinary vegetables are different. In Taiwan, the plants of the plant factory only need to be verified by rigorous scientific standard data. Indoors, the detection of air dust is a technical standard of one cubic centimeter of dust content of 100,000. If this standard is met, it is identified as clean. The standard of clean room is 10,000 dust per cubic centimeter, while the average food processing plant is 100,000. The plant factory is not a clean room, so it is enough for the plant to meet the environmental requirements of the food processing plant. The dishes that have come out have reached the standard of raw food.
4. Are there any studies on the plants grown in plant factories that have defects in function or performance? Will artificial planting change the structure of the dish, or other similar genetically modified problems?
Fang Wei: Artificial light is basically the same as sunlight, and there is no difference in the growth of plants. The only difference is that if the plant is reddish, you will use the exact spectrum, it will produce lettuce with normal coloration of red leaves, but you said that the lack of anthocyanins in vegetables will be different, but less nutrients. The dishes that may be planted by the water culture system will be tenderer. Some people like it very much. Some people say that it is unnatural. People are the only animals that wear clothes, but we don’t feel unnatural when we wear clothes, so don’t take the word nature. Unlimited magnification.
Plant factories use data to speak. We adjust the light to produce a beneficial component. The ratio of blue light to red light in the sun is fixed, but the lighting can make more of the ingredients we need, but it does not change the vegetables. Genes, this is the ability of the plant itself, we have not changed the genes of plants.
Nutritional ingredients are the end use of vegetables. Some nutritional values are higher. Some nutrients are not what we need. When we need a certain component of plants, we can regulate them through physical conditions. This is the benefit of plant factories. The growth of beneficial components of the human body, or by changing the growth environment of the vegetables to adjust different tastes.
