LED plant factory "cheat" strawberry rich in summer

Global climate change and extreme weather, resulting in food production, coupled with the urbanization and pollution problems, food security Quanliang red. The United Nations Food and Agriculture Organization (FAO) prepared the Price (Food) in the 20 years from 1993 to 2012, the total index grew by 102%, of which, the price of cereals increased by more than $142%.

Japan's 311 earthquake caused the Fukushima nuclear disaster, a lot of farmland between the waste tillage, Japanese food is not at ease. In this situation, to provide a stable output and safe LED plant, bring a new wave of business opportunities, and may even become a safeguard to maintain the survival of mankind.

Simulated natural cheat strawberry rich summer

Plant factory is a system that makes full use of artificial light source, which can control the humidity, temperature, gas concentration, and almost closed environment. In order to take care of the "rich", the plant factory must set specific spectrum, using LED light source lamp plant said, and perennial maintain suitable for plant growth temperature. In order to reduce electricity costs, some factories will be combined with solar power generation equipment, the production of energy.

Plant through the simulation of nature, trying to deceive the plant, so that plants grow with human needs. Taiwan ITRI industrial service center senior researcher Lin Yi bird said, "in the best condition, plant factory plant growth season does not change completely. In other words, the production of watermelon in the winter, the summer production of strawberries can become the norm.

In recent years, Taiwan area has a number of science and technology industry into plant factory production, billion light and new century, EPISTAR, canyuan etc. have been put into use in plant cultivation LED light source. However, the Taiwan market is small, the high cost of production and plant factory, so that the economic benefit is still difficult to show.

In Japan, in three or forty years ago, the development of plant related technology, the industry has developed a production of transgenic plants, used as a protein drug raw materials. In addition, also can produce the ultra low potassium content of lettuce, can provide the patient with kidney disease, the added value increased significantly.

Food safety and nutrition

Completely artificial light LED plant factory production of hydroponic culture, without soil, plant growth required nutrients from artificial nutrient solution. Such a highly artificial environment, many consumers questioned the safety and nutritional value of products. Experts pointed out that the plant plant in good control, product safety and quality can not lose general agriculture.

Consumers hear the LED plant, the most frequently asked questions include: "do not produce plants under natural environment can eat it? Is the plant organic? "," lack of soil, plant nutrients enough? Fang Wei, director of the Department of mechanical and electrical engineering, said the plant is not organic farming, but under the proper control of safe. People sometimes use pesticides and fertilizers as great scourges, but the real key lies in the amount, but not completely without.

There is no sunshine in the plant factory, and the outside world is suspected of causing the high nitrate content in the plant body to be affected by the residual nitrate. Fang Wei, clarification, and light on nitrate residues in plants, the plant factory vegetables produced through LED light source, to keep nitrate concentration at 2000ppm under field cultivation if no attention, but the content of nitrate can reach more than 5000ppm, not necessarily safer. On the other hand, the human body will naturally be able to metabolize nitrate, as long as the concentration of the following is not a problem for health.

For some people questioned the lack of trace elements or hydroponic vegetable nutrition, Fang Wei pointed out that the mining plant hydroponic factories in order to reverse osmosis plant or pure water, nutrient into the water by manual or automatic mode, if the plants are missing what elements, not the hydroponic fault, but the human factor, which can avoid.
