Everything grows by the sun, and light is an indispensable link in the growth and development of agricultural organisms. Many experts from the semiconductor lighting industry and agricultural experts said in an interview on the 3rd that intelligent lighting and precise control of light links are the inevitable trend of modern facility agricultural technology development. LED agricultural lighting will become the next generation of modern facility agriculture. light source.
Agriculture is the foundation of the national economy. With the growth of population, the increase in the quantity and quality of agricultural products, and the continuous reduction of agricultural resources, environmental pollution is deteriorating, posing a real challenge to national food security, food security and the effective supply of agricultural products. Facility agriculture is the main body and pillar industry of modern agriculture. It is a modern agricultural method that uses engineering techniques to carry out efficient production of animals and plants under relatively controllable conditions. Covers planting, facility farming and facilities for edible fungi.
According to media reports, in 2012, China's facilities and horticultural area was more than 57.9 million mu, and the net production value of facilities and horticulture industry was more than 580 billion yuan.
At present, in China's facility agriculture, traditional artificial light sources include high-pressure sodium lamps, fluorescent lamps, etc. These artificial light sources have the disadvantages of high energy consumption and low light efficiency. Dr. Li Tao from the Institute of Agro-Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences introduced that the spectrum required by plants is a blue light portion of 400-500 nm, which is not available in traditional artificial light sources.
Li Tao said that the emergence of LED artificial light source provides a very effective means to achieve the goal of energy-saving and high-efficiency light source. It can be arbitrarily combined according to plant needs, consumes 1/5 of the high-pressure sodium lamp, and does not require preheating. The high-pressure sodium lamp is turned on. After a period of time, it takes a long time to warm up, the LED light source does not need to be preheated, and the service life is long.
Despite the many advantages of LED lamps, high pressure sodium lamps are still the most important artificial light source in greenhouse production systems. Li Tao said that the main reason for this phenomenon is that the price of LED artificial light source is relatively high, and the wide application of LED artificial light source in greenhouse production system is still in the stage of promotion and research and development. However, with the maturity of LED technology, reduced production costs and fierce competition, LED prices will drop rapidly, which is beneficial to the application of LED lighting in future agriculture.
Relevant data shows that since 2010, the annual growth rate of Guangdong LED industry has reached more than 25%. In 2014, the total output value of LED industry in Guangdong Province was 346.06 billion yuan, a year-on-year increase of 23.09%.
