Lighting plant factory production LED agricultural era

Mirai Japanese company ( Headquarters in Tokyo) In miyagi, the urban construction all cultivation with a LED lights are all made of artificial light type plant factory. According to the company, this is the world's largest plant are all made of LED lighting factory. Every day can produce 10000 head of lettuce.

Mirai SONY sendai technology center is miyagi Renaissance 'industrial park' in existing buildings converted into plant factory. As Japan's ministry of economy of northeast economy, trade and industry bureau of finance business, one of Mirai after suitable plant cultivation environment technology development and development of LED lighting as the theme of the factory, and GE Japan jointly conducted empirical test. The whole plant design, construction and cultivation of rack kajima corporation is responsible for the development by Japan.

is the biggest characteristic of the plant, using GE Japan for plant factory development of LED lighting, adopted to evenly dispersed high directivity LED light and according to different wavelength of light irradiation plant growth stage. For example, in the early stage after out of the nursery room, light white and red LED light source mixing partial white light to promote the photosynthesis. Then, irradiation by equipped with red and blue LED light source of LED lighting from the partial red light to promote the growth of leaves and roots. Closer to the harvest, again illuminate partial white light to promote the photosynthesis. After using this method, compared with only using fluorescent lamp, not only power consumption reduced by 40%, a 50% increase over the same area yield also. In addition, the Mirai did not disclose specific techniques related to LED lighting light wavelength.

to take advantage of the ceiling as much as 7 m of buildings, the layer also developed a 6 m high cultivation. Will not only lighting appliances and nutrient solution circulation system and is an organic whole to improve the function, also by using the general cultivation of material measures such as reducing the cost. In addition, kajima imported the cultivation environment simulation technology, the use of the company after the cultivation in the process of construction technology in plant factory. According to the company, in order to avoid because of the multilayer of cultivation in the height direction have obvious difference, such as temperature, air velocity and intensity of illumination, the repeated calculation, layout and design of the air conditioning and equipment configuration.

15 layer by using LED lighting and cultivation, increased the yield per unit area, improved the yield of plant factory. According to Mirai, the knot ball lettuce retails for about 200 yen. Although the company did not disclose the wholesale price, but said 'herbs such as there is not much difference, open-air cultivation and sometimes cheaper plant cultivation of plants. Lettuce, etc of the average price is higher than the outdoor cultivation, but when meet with open-air lettuce prices, both will be flat '( Mirai representative directors President island village mau treated) 。

the plant is cultivated upright, endive, lettuce Mosaic water celery, lettuce, and lettuce and other 6 kinds of leafy vegetables, from sowing to harvesting time is 33 ~ 35 days. The factory production in early May 2014, June 20, began to supply. Cultivation of vegetables has begun at the local supermarket. The factory will be in the summer of 2014 formally put into production, annual sales target for hundreds of millions of yen. Mirai experience company also plans to use the technologies such as plant factories for export.
