Study on the significance and innovation of LED applied in tissue culture seedling plant

Group is a culture, can get a lot of homologous parent gene seedling biological technology, has formed a large scale industrial application market, widely used in agricultural and horticultural production, ecological and economic forest cultivation, is one of the pillars of modern efficient agriculture. Foreign LED is increasing in plant tissue culture and plant tissue culture on the research and application of the promotion, this is because the industry and plant tissue culture seedlings depends entirely on the electric light source, which provides a huge market for electric light sources, LED will be the first in the industry to obtain a breakthrough application.

The new LED light source 1 plant tissue culture and breeding industry in urgent need of high biological efficiency

Electric light source is necessary for the current widespread use of tissue culture, the traditional electric light source. But the traditional electric light source of the plant energy efficiency is only 0.5%, electricity waste is great, the cost of electricity accounts for about 30%~40% of the total cost of tissue culture seedlings. Therefore, the application of a new type of LED light source with high biological energy efficiency will lead to the profound transformation of the plant tissue culture industry, and promote the expansion of the scale of the seedling industry, and promote the application scale of LED.

2.LED light source has remarkable energy saving effect and persistence in plant tissue culture in the consumer market

Electric light source is essential for tissue culture and consumables, so special light source of LED tissue culture has broad lasting consumer market. China is the global production base and export base of plant tissue culture, and also the largest market of tissue culture seedling in the world. Since the middle of 1990s, the Chinese mainland to undertake the global industrial group to cultivate seedlings of industrial transfer, and now this industry transfer process has been completed. According to the Ministry of agriculture statistics, by the end of 2007, annual output of more than 10 million strains of the enterprise culture, more than and 300 nationwide, the total area of the plant tissue culture in more than 20 million square meters, the total output of more than 3 billion lines, the output value of about 20 billion yuan. Tissue culture and daily illumination time is 16h/d, if 300 days a year according to the production date, the total area of 20 million square meters in calculation, is caused by a fluorescent lamp in total power consumption over 107 billion 500 million KW/h; with LED, the annual total power consumption is about 51 billion 800 million KW/h, the total annual energy in more than 56 billion KW/h. The energy saving effect is remarkable.

In the "11th Five-Year" period, Nanjing Agricultural University is in charge of the National 863 high technology research program "semiconductor lighting project" major project, through the implementation of the application of semiconductor lighting source in plant tissue culture "(2006AA03A165), the mechanism of the National Natural Science Fund Project" the effect of environmental regulation on Photosynthetic Characteristics of sugar free tissue culture plant growth and development "(30800764) and Jiangsu Province Natural Science Fund Project" plantlets of large-scale breeding of micro environment optimization regulation model "(BK2004107) research, has mastered the application principle and key technology of LED in plant tissue culture seedling, laid the foundation of application technology, 3 kinds of special light source sample tissue culture has been developed, the principle and the technical reserve for further application. At present the work need to do is to apply the results to the factory and the whole plant tissue culture industry, with special LED 1~2 tissue culture seedling tissue culture light source equipment enterprise, form a demonstration of the display, which can be used for the promotion of demonstration, and for experts, leadership inspection and guidance, to fully market-oriented development lay base.
