"LED plant growth light" in Nanjing

Light is essential for plant growth, energy sources, Nanjing Agricultural University has recently successfully developed the sun substitute - LED (light emitting diode) plant growth lamp, the lamp may be different for different plants and plants in different growth stages of tailored light.

South agricultural university professor Dr. Xu Zhigang introduced, they assumed the national "863" high technology research program in the semiconductor lighting application in plant research ", has mastered the knot, application principle and key technology of LED in plant breeding in factory. In other words, with the foundation of industrialization, LED applications in agriculture and biology will be expected to become a new area of development of Nanjing LED industry.

The radish leaves light

There are a variety of ways to increase crop yields, one of which is biotechnology, such as hybrid rice produced by Yuan Longping, a chemical method, such as chemical fertilizers, pesticides and hormones. What we are exploring is a physical way to try to promote the growth of plants through the regulation of light, and gradually reduce the excessive dependence of modern agriculture on chemical technology. Xu Zhigang said.

Light has a magic power, a role in the regulation of plant photosynthesis, growth, morphogenesis and metabolism, and now in the greenhouse, greenhouse cultivation, light up the sun the deficiencies are generally used for fluorescent lamps, high pressure sodium lamp and incandescent lamp, the spectral energy distribution of light source is designed according to the human eye demand for light, and the spectra of the plants to grow and human needs are not the same. According to the special subject of the Agricultural University of South China, LED wavelength type is rich, adjustable room for large, suitable for plant lighting.

Such as carrots and vegetable needed in the process of cultivating the light control is not the same, can according to their own preferences configuration of different LED lamps; in the process of the cultivation of sprouts, leaf size, chlorophyll and carotene and vitamin content, can be achieved through the regulation of illumination.

LED light to reduce the cost of plant cultivation

Factory nursery has been an important support for modern agriculture, but also the development of Agricultural University of South Korea LED lamp first application areas. In the nursery workshop, a variety of flowers, vegetables, seedlings arranged neatly on the shelf, and the top of each shelf are installed LED lights, these seedlings are used for export.

"Traditional light sources need to be equipped with 0.5 kilowatts per square meter of light, while the LED only need to be 0.27 kilowatts, so that the power consumption can be reduced by about half. Xu Zhigang said. Power is on the one hand, the application of this new type of LED light source, more able to restore the original appearance of plant growth, greenhouse cultivation of cucumbers, tomatoes and other taste is not good, there is no reason to shine light.

It is understood that the research direction of this LED lamp there are a lot of space extension, can not only realize the intensive plant production, reduce the use of plant hormones and other chemicals, can also be used for physical control of agricultural pests, LED light source adopts the specific wavelength of killing pests; can also be used in animal breeding, with specific wavelength LED the implementation of light to promote animal production, reduce the occurrence of disease, reduce the use of feed additives and hormones etc..

LED industry to bring billions of dollars to develop space

Only plant factory seedling industry for a LED light source provides a huge consumer market, according to estimates of South Nongda research group, only a seedling reached a huge amount of exports to tens of billions of lines, domestic consumption is larger, if the use of LED in plant nurserying to replace the traditional electric light source, the one-time the total market size will reach 200 billion yuan.

Scientific research projects have come to an end, the next step is the real estate industry. In accordance with the plan of the Agricultural University of South, the key work is to use plant seedlings dedicated LED light source equipped with 1 - 2 plant nursery enterprises, for the promotion of demonstration, and then make the formation of LED plant light industry.

Our R & D results have a series of parameters, in the process of LED industrialization, as long as the application of different parameters can be changed according to the direction of. Xu Zhigang said.

A small forum held on the day before, the parties concerned --

Development of "LED", Nanjing how to do?

Nanjing LED (semiconductor light-emitting diode) industry development forum held recently in Nanjing International Expo center. From the domestic and foreign experts in the LED industry and the Nanjing government departments, representatives of local enterprises are enthusiastic and straightforward dialogue. The development of this emerging industry in the view of the views of the parties to see more clearly.

Nanjing LED industry to achieve sales plan in 2012 more than 15 billion yuan, divided into LCD backlight, lighting, devices, display of the top product groups, including LED lighting sales plan of 2 billion yuan. "This paragraph of words on the screen to play out, the Expo Center 209 meeting room temperature suddenly increased.

On behalf of sitting in the second row of Nanjing Henderson stood up and said that this year is the first year LED industry development, the market is expected to have exploded, is only LED in the lighting lamp market has huge capacity, Nanjing enterprises in terms of lighting output should be far more than 2 billion yuan.

This voice, on behalf of over neiic received the words, agrees, lighting business neiic integration and its original Huadian Sanle lighting, a series of LED in the field of development planning.
