Xinli light source uses LED lights to grow the cherry

No need for soil and sunlight, and intelligent plant production at any time and place. The output per unit area can be several tens or even hundreds of times higher than ordinary farmland. This "artifact" that subverts the concept of "all things depend on the sun" is actually LED plant-specific light. LED plant lighting technology, which is indispensable in this plant factory, is a product independently developed by Sichuan Xinli Light Source Co., Ltd.

At present, the company based in Chengdu has not only developed LED plant lighting products, but also established a plant factory experiment base in Changchun, and has successfully planted a cherry that cannot grow in the northeast region.

Rare earth phosphor

Customized "light" for vegetables

On June 1st, LED plant lights developed and produced by Xinli Light Source were officially unveiled in the National Twelfth Five-Year Science and Technology Innovation Achievement Exhibition. Wang Sen is the person in charge of R&D. He introduced that the LED plant lighting at the exhibition site uses the T8 integrated plant lighting lamp developed and produced independently by Xinli Lighting. He said that this technology and product appeared in the national "Twelfth Five-Year" technological innovation achievement exhibition, "because the current technology is unique in the world!"

What is the principle of this technology? "The T8 integrated plant lighting is based on the AC-LED lighting technology independently researched and developed by Xinli Lighting. Through accurate rare-earth phosphor ratio, the light source can provide targeted and accurate light ratio according to different plants, effectively promoting the plant's photosynthetic efficiency. The role is to create more suitable conditions for plant growth." Wang Sen said that the biggest function of LED plant lighting is to tailor the light spectrum of plants to meet the needs of the light, can be customized for different types of plants in different growth stages, light quality Light cycle.

“Rare earth phosphors are unique patents of Xinli light source. Currently, Xinli light source has 1015 national patents, and there are more than 20 patents on plant lighting.” In Wang Sen's opinion, special spectrum is like different ages. People in the segment are equipped with infant milk powder and middle-aged and elderly milk powder, which allow people to absorb useful nutrients. The contents of plants, vitamins, and sugars grown in the LED light environment are almost unchanged. Thanks to ample light sources, the plant's photosynthetic efficiency increases and the plant's potential can be fully realized.

The production technology of plant factories has taken the lead in forming countries with limited land resources such as Japan, Israel, and Denmark. However, in recent years, China has gradually started to build plant factories and continuously promote localized technologies.

Instead of planting in the ground and not using the sun, how does a smart plant factory produce fruits and vegetables using an "assembly line"? At present, Xinli Light Source and the Institute of Geography of the Chinese Academy of Sciences have set up an experiment base, Zhongke Optoelectronics (Changchun) Co., Ltd. in Changchun, and has achieved mass production of lettuce, eggplant, cherry tomatoes, strawberries and other fruits and vegetables.

According to Wang Sen, in addition to the plant's “preference” for different spectra, the corresponding LED light was selected to replace sunlight as a light source, and 24 hours of uninterrupted light was applied, as well as temperature, humidity, light, airflow, and carbon dioxide concentration in the plant factory. Nutritional fluids and other environmental elements are automatically monitored in real time to ensure maximum photosynthesis. Compared with the traditional planting model, the land use rate is high, the operation is labor-saving, the degree of mechanization is high, the product safety is pollution-free, and the nutritional value is greatly improved.

“Through the high-precision control of the factory's environment, the growth of plants is almost unconstrained by natural conditions and the growth cycle is accelerated.” Wang Sen said that lettuce, pakchoi, etc. planted in plant factories can be produced in about 20 days. Harvesting, while in ordinary fields, it takes from one month to 40 days. In the experiment, vegetables such as eggplant only increased yield by more than 2,000 kilos per acre, which greatly increased the income of growers.

The success of the experiment at the beginning of this year is to fill the gap in the Northeast can not grow the cherry. Wang Sen said that in the past, it was impossible to eat the real estate of the cherry in Changchun. Because of the light, the cherry could not grow in the Northeast, and this year's Spring Festival in Changchun experimental successful cherry, although the price reached About 180 yuan, still in short supply.
