The 15th China ( Shouguang ) International Vegetable Science and Technology Fair will be opened in Shouguang International Convention and Exhibition Center on April 20 2014 . the reporter went to fair to visit various venues on April 17 2014, the plants growing without sunlight attracted the attention of reporters .The reporter saw that the lettuce with more than a dozen centimeters tall was “quiet ” growing under the purple light in plant factory of 10th Hall of the fair ,.
The plant factory ” completely without sunshine” and was equipped with LED grow lights in each cultivation shelves, irradiating for 24 hours according to the different plants using different LED light , regulating plant growth period . Because the environment can be freely controlled in plant factory , carbon dioxide in cultural environment can be greatly increased, so that the efficiency of photosynthesis in plants is increased , the formation and accumulation of nutrients in plant biomass are times more than that of conventional cultivation.
According to Hall staff, the solar glass laid above the plant factory can absorb the “energy” from the sun, which connected with the network below the factory assembly plant by a few lines , which is called the LED grow lights, “This ecological agriculture greenhouses is just the integrated photovoltaic application, the top of the photovoltaic power generation system consists of solar modules and inverters composition, which can provide reliable power for the greenhouse and fill light according to LED grow lights for the plants. The generated electricity can be used to support the daily operation of agricultural equipment shed , but also to the grid .Browsing http://www.lead-lighting.com/products/bid33-1.htm for more information about LED grow lights.
