Recently, the Shanghai Semiconductor Lighting Engineering Technology Research Center under the Shanghai Science and Technology Commission and the Sunqiao Agricultural Park have cooperated to introduce LED lighting systems into vegetable greenhouses and greenhouses to ecologically supplement crops and conduct pest research. Crops grow healthily.
As LED technology becomes more and more mature, LED light sources are gradually introduced in agricultural production. Compared with the current supplemental light system using fluorescent lamps or high-pressure sodium lamps as artificial light sources, LEDs have the advantages of adjustable light quantity, adjustable light quality, low cooling load, and the ability to increase the cultivation amount per unit area. Controlled agricultural production environments (such as plant tissue culture rooms, plant growth chambers, etc.) are a very suitable artificial light source. And LED has begun to be used in agricultural production, such as NASA's first LED application in space agriculture. Experiments have shown that LED monochromatic light of a specific wavelength is particularly attractive to specific pests. The key to the joint research of Shanghai Semiconductor Lighting Engineering Technology Research Center and Sunqiao Park is to find more perfect combinations. By adjusting the light wave to specifically attract insects and eliminate pests, not only the agricultural products are greener and safer, but also the energy-saving effect is quite obvious. According to estimates, the power consumption of LED light sources is only about 20% of ordinary light sources. In the past, factory-based seedlings were most afraid of lack of light in the rainy days, and they had a "high-footed seedling" with low survival rate. Although it is used by ordinary light sources to fill light and open small stoves, it has high energy consumption and high cost. Nowadays, the fill light made of LED light source not only saves electricity, but also can grow plants. According to the blending, not long ago, the Kuwaiti princess came to the Sunqiao Agricultural Park to buy LED eco-filled lights on the spot to return home.
