LED agriculture may face basic research and cost bottlenecks

Compared with the traditional light source, in addition to energy-saving features, LED also has a narrow wavelength, pure light quality, high efficiency, rich wavelength and spectral energy modulation convenient and low heat generation, small volume, long life and other advantages, to facilitate centralized plant required the implementation of a balanced wavelength brachytherapy.

In recent years, the research and application of LED with various wavelengths in agriculture has been widely concerned and has become a new hot spot in LED lighting applications.

LED as a plant lighting source can be widely used in plant cultivation, greenhouse, plant tissue culture, plant lighting factory, has promoted plant growth and regulation of plant morphogenesis, energy conservation and environmental protection and many other advantages. LED not only can send out light narrow monochromatic light, such as red, orange, yellow, green, blue, and infrared, but also according to the different needs of any combination of plants and animals, but also the low heating characteristics of cold light source, can close distance irradiation plant, improve space utilization.

China Academy of deputy director Chen Hongda stressed that the LED light source can not only provide reasonable light environment for agricultural biological growth, reduction of pesticide, hormones and other chemicals, to ensure food safety, and low energy consumption of green light source, has a broad application prospect, is an important development trend of the future of lighting plant.

Chen Hongda said that despite the current application of LED in the agricultural field of lighting is still in the initial infancy, but with LED as the artificial light growth of intelligent control on crops, has changed the traditional mode of agricultural production, has a very good development prospects.

Basic research and cost issues are bottlenecks

At present, the relevant research is still in the initial stage of the mainland, for the specific needs of plant growth needs to be raised, even if the domestic LED industry with the relevant technology, the hero is also difficult to use. At the same time, the cost of LED is also the bottleneck restricting its large-scale application in agricultural production.

The industry said that the current European and Japanese LED agricultural applications are more developed, mainly because they are on the basis of agricultural research in the front. As a well-known foreign flowering lamp lighting enterprises as an example, because of the need to repeat the experiments in a growth cycle of flowers, so the company with scientific research institutions and farmers together for 10 years before the success of baked products. In addition, some herbs in the course of growth after LED irradiation, the drug will be improved, but it also requires a lot of time for clinical trials.

Agriculture is still a new field of LED lighting applications, on the one hand, the need for agricultural experts, plant experts, optical experts and other joint efforts to complete a large number of scientific experiments and application experiments. Chen Hongda said, on the other hand, the cost of LED is also restricting its large-scale application of agricultural production bottlenecks. "Chen Hongda said, because the cost is too high, not only in domestic, even to promote LED lighting application in agriculture in Holland, Israel, Japan and other countries, LED lighting is also confined to flowers, herbs and other high-value crops. I believe that with the continuous progress of technology and the localization of MOCVD equipment, LED cost reduction will accelerate its application in agricultural production.

"The development of LED agricultural lighting industry requires not only the joint efforts of scientific research institutes and enterprises, but also the support of relevant national policies. Guangdong outrace Technology Co., the relevant responsible person said. At present, China's governments at all levels have introduced a series of policy measures to promote and encourage the development of LED lighting industry, but the LED lighting industry is still very little concern. The responsible person said, centralized planning the construction of a number of vegetables, flowers, tissue culture, Chinese medicine and poultry farming and other agricultural enterprises LED product demonstration base, develop agricultural LED subsidy policy, will be the effective ways to promote the agricultural development of LED lighting industry.
