The development of LED lighting plant

With the deepening of the research of semiconductor luminescence material, LED manufacturing technology progress and the development and application of new materials, LED the development of the breakthrough progress has been made, prices also fell sharply, and its application in the studies of plant facilities cultivation by international scholars gradually attention.Especially in the high brightness LED after the success of the development, are widely used in plant physiology or research in the field of culture, as the light morphogenesis, photosynthesis and chlorophyll synthesis, etc.

In the 21st century is the century of ecological agriculture, the physical agriculture is one of the main ways to realize ecological agriculture, in numerous physical discipline knowledge, in which optical plays an important role, therefore, some scholars think that "the century of light" is coming.How in particular artificial light under the sun light regulation of green plants to implement different "light weight", not only promote crop growth and development, also can achieve production, high efficiency, high quality, disease resistance, pollution-free, the purpose of this to promote the development of China's modern agriculture has very important practical significance.

LED by its inherent superiority is attracts the attention of the world, especially in the global energy shortage concerns rise again under the background.Applying LED to plant facility cultivation areas has many advantages: can provide a variety of pure monochromatic light and complex spectrum, can according to different crops and different growth period to provide the corresponding spectral combination;Has the PPFD adjustable features, can be used to simulate the change of the intensity of sunlight;Light frequency and duty cycle adjustable features can provide high frequency interval to light model, is helpful to explore photosynthesis in the Ming period and dark period of control mechanism, and can expand the energy saving space.
