There is a scene in the movie "The Martian": Astronaut Mark, who stays alone on Mars, uses technology to make his own fertilizer and grow potatoes on Mars. It is said that movies are derived from life, and it is true. There is also such a scene in Foshan, Guangdong.
Guangdong Modern Agricultural Application Demonstration Base-Plant Factory, located in Luo Village, Nanhai, Foshan City, Guangdong Province. There is a house of about 150m2 in which there are 4 layers of three-dimensionally cultivated green vegetables growing, and a row of LED plants are installed on each layer of the shelf. Lamp, there is no soil under the green vegetables, instead a trough of nutrient solution is used.
Sui Shirong, the person in charge of the small plant factory demonstration base, introduced that this is a feature of modern plant factories. The nutrient solution is more conducive to controlling and supplementing plant nutrition, and it is also conducive to the absorption of nutrients by plants. LED plant lights can help promote plant photosynthesis. The location provides light, and uses LED materials, and the spectrum can be customized output, which means that almost only the light waves needed for plant photosynthesis are emitted, which is energy-saving and environmentally friendly, and can greatly improve plant yield and quality.
According to Yang Qichang, director of the Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences, LED technology is becoming more and more mature, and the wide application of mainstream living lighting and commercial lighting has also driven the development of LED special lamps. LED plant lamps are one of them. First, there are currently more than 100 plant factory experimental bases in China where LED plant lights provide light.
Director Yang also introduced that the plant factory is a concentrated expression of the development of scientific and technological agriculture. Compared with traditional industries, it has many advantages: first, it effectively avoids the influence of external natural factors in the process of plant growth, second, greatly improving the efficiency of space utilization, and third It is easy to manage and has a high degree of automation. The fourth is energy saving and environmental protection, which can effectively avoid industrial pollution from traditional plant lights. The crops grown with LED plant lights are greener and more nutritious.
Chen Sianqiu, director of the Science and Technology Education Division of the Department of Agriculture of Guangdong Province, said: LED plant lights join the big family of science and technology agriculture, accelerate the organic integration of science and agriculture, and use the factory model to develop modern agriculture. Farmers can add value and increase production, and consumers' food safety More security is a win-win development route.
At present, there are still many challenges. First, the emerging industry of LED plant lights is still in the early stage of development, various standards have not been formed, and the market is also uneven. It needs to be polished by the development of market economy. On the other hand, plant factories. The development has just begun. Many technologies are immature and cannot be promoted on a large scale. They just set up test bases across the country. Finally, my country started late in the field of using LED plant lights to realize scientific and technological agricultural plant factories. As a large agricultural country, it takes a long time to complete the transformation.
Based on the current challenges and opportunities in the development of LED plant lights and plant factories, it is believed that the development of scientific and technological agriculture will attract more and more people’s attention, and the suffering will eventually pass. Large-scale plant factories will also bring more life to people’s lives. How convenient.
