Plant factory's "light" glow years

" three years from now, china's plant factories will spring up. There will be more commercial plant factories, there will be a huge increase in the variety of plants that can be produced, and prices will be cheaper.
Today, the development of plant factories confirmed Li Shaohua's prediction three years ago: a number of Wanping plant uprooted, vegetables and fruits, medicinal plant quality production, plant factory equipment and technology out of the country, bright "Chinese business card", a period of plant factory "light" years, is ushering in ...
Li Shaohua is a researcher at the Institute of Plant Research (hereinafter referred to as the
Plant Institute) of the Chinese Academy of Sciences and the Director of the Institute of Light Biology of Fujian Province, China Science biology Co., Ltd. (hereinafter referred to as Chinese Science Biology). In a recent interview with China Science Daily, he again stressed: "Plant factories subvert traditional agricultural production, is the highest stage of modern agricultural development, to solve the contradiction between population and resources, to ensure national food security and national defense strategic needs are of great significance."from relying on the world, to the traditional facilities represented by plastic sheds, agriculture, although it has made great progress, still faces serious pests and diseases, excessive use of pesticides, low yield of land, mechanized automation level is limited and so on.
, rising labor costs, frequent natural disasters, and increasingly acute conflicts between population and resources... A "revolution" that subverts traditional agriculture is imperative.
" in the 100,000-level purification workshop, through lighting, temperature, humidity, CO2 and nutrients and other factors of intelligent control, can be efficient, high-quality and safe vegetable production, to achieve a stable, continuous supply of vegetables throughout the year. Li Yang, associate researcher of
Plant Institute and director of the Plant Factory Research and Development Center, told China Science Daily, "The plant factory of Chinese Science and Technology has integrated a series of independently developed cultivation module equipment, professional plant light source system, nutrient solution formulation and control system, intelligent environmental control system, and realized the control of the whole production process."
He further said that based on efficient LED spectroscopy and nutrient fluid regulation technology, a controlled clean environment, plant plants are dozens or even hundreds of times more productive than traditional agriculture: can produce more than 20 times a year, vegetable production and quality is fully controlled, and nutrition is more balanced. The first international 10,000m2 vegetable factory in Hutou Town, Anxi County, Fujian Province, can produce dozens of vegetables, and currently has 8 main varieties, from seeding to harvesting only 35 days, with 1.8 to 2.0 tons of daily vegetables.
" plant factory green pollution-free, vegetable production process does not use any pesticides, to solve the traditional vegetable production process heavy metal pollution and pesticide residues and other food safety problems. Li Shaohua said the vegetables from the plant factory also completed the 2017 BRICS leaders' meeting in Xiamen.
At present, plant factories produce plant species concentrated in leafy vegetables (lettuce, cabbage, ice vegetables, sprouts, etc.), fruit vegetables (tomatoes, bell peppers, cucumbers, etc.), edible flowers and medicinal plants, of which medicinal plants to gold line lotus, rice and other high value-added medicinal plants.
" compared with three years ago, plant factory product variety increased significantly, prices have been stable, in no man's land at an altitude of 4,300 meters to achieve vegetable production container plant factory, for the national strategic needs to provide a guarantee. Li Shaohua said.do you want to replace the sun with the sun? This has to be mentioned as one of the key technologies of plant factories - plant light formulation regulation technology. It's not that simple to combine biology with LED luminescence technology to produce suitable plant lighting fixtures.
different plants require different light formulations, and different stages of plant development require different light. "In the case of lettuce, for example, the nursery stage requires more blue light to make the seedlings strong, and later, more red light to accelerate plant growth. If necessary, special light formulations need to be added before harvesting to improve the quality of the product. Li Yang said.
reporter learned that a mature light formula generally need to study 1 to 2 years, individual medicinal plants need 3 to 5 years or more.
Li Yang, a professor of science, told the China Science Daily about their journey of "making light".
first of all, to study the nature of plants and the need for light in the external environment, and then study dozens of monochrome light in plant growth and development process, which usually takes six months to a year. At the same time, studies are needed on the effects of monochrome light combinations on plant growth and development processes, which can take half a year.
basic study, followed by the photorealic formula (spectral) study. Successful replacement of sunlight requires ensuring that different plants have the right light quality formula for different development cycles, including monochrome light selection, energy distribution, and application effects. In addition, considering the cost of electricity and the output benefit on the basis of the photorealic formula, it is necessary to study the effects of lighting time, light intensity and mode on plants, and obtain the appropriate light formulation.
next, in the technology of photon formulation, the use of different types of LED lamp strains, simulation of the resulting spectrum, combined with LED luminescence efficiency and lamp development costs, the development of energy-efficient plant lighting fixtures.
and lamp production applications are the best way to test the maturity of the technology. Li Yang recalled that in the early stage of the production of gold line lotus, the leaves of the gold line lotus appear to return to green phenomenon, does not meet the high-quality gold line lotus gold line clear, leaf back red production requirements, cultivation technology and production conditions have not changed, only lamps are new, the greatest possibility of problems. However, at that time dedicated to the gold line lotus growth lamp has been stereotyped and large-area layout, the cost of replacement is too great, the pressure came.
is in Xiamen laboratory Li Yang rushed back to the lake head test base, in the plant "squat" for two hours, carefully look at the front of the golden line lotus and the factory corners, from the performance of the gold line lotus in different light, to temperature, humidity, ventilation and other environmental conditions, as well as the cultivation of the gold line lotus substation and other cultivation containers, he found that the cultivation of the upper layer of the gold line lotus leaves than the lower layer of red, away from the air-conditioned air vents at the leaf.
" problem is probably the temperature! With "squatting" thinking, Li Yang wrote a two-page analysis, a detailed analysis of each possible factors, after continuous trial and exclusion, the results confirmed his guess. Through continuous feedback and debugging, they finally solved the production problem of gold line lotus, the first international commercial plant plant (golden line lotus), to produce high-quality gold line lotus products, compared with other production models, the active ingredient content of gold line lotus increased by more than 48.52%. good technology, attract good enterprises, good products, win good markets.
day, the
welcomed a group of special guests, the domestic photoelectrelectr industry leading enterprises Fujian Sanan Group. In a collaboration between Sanan Group and NASA on plant lighting fixtures, the great potential of LED technology in the plant factory market was discovered, and the
Plant Institute was found in the hope of establishing a plant factory.
fact, the United States, the Netherlands, Japan, South Korea and other countries have built a number of plant factories in the early days, some developed countries have begun in China to demonstrate the promotion of the plant factory industry as the goal. Areas with limited natural conditions, such as metropolises and cold droughts, will be potentially competing for markets. Preempting the moment has become urgent.
With the vision of becoming the "leader" of international plant factories,
Plant Institute and Sanan Group jointly built Fujian Province, China Science and Biological Co., Ltd., under the headquarters of Chinese science and technology biological base, plant factory research institute, industrialization base. "The company's industrialization demonstration is carried out at the same time as research and development, combining the development and application of key equipment and technologies for the industrialization of plant plants." Li Shaohua said.
In order to better motivate researchers, China Science and Technology has also formulated the Measures for the Administration of Intellectual Property Rights, which, while protecting intellectual property rights, encourages invention and creation, increases the setting of year-end patent awards, and adopts patents and know-how as reference projects for employee promotion assessment. "The implementation of this system has contributed to a significant increase in the number of patent applications, with the number of patent filings for inventions increasing by 340% year-on-year in 2018 and the number of domestic and foreign patents granted and accepted reaching 189, an increase of 372.5% year-on-year." Li Yang said.
Pointed out that industrialization as the goal is both an incentive and a challenge for the scientific research team. Researchers from doing experimental articles, to drilling technology, patent evaluation, market application-oriented research.
With the support of the "Hongguang Special Project" of the Chinese Academy of Sciences, The Chinese Academy of Sciences has invested in the establishment of a number of direct plant factories, a total area of 80,000 m2 of standardized plant in Lakehead, Anxi County, Fujian Province, products are sold to more than 200 business super, hotels and restaurants.
addition, Cosco will accelerate the development and export of equipment, and take a stake in technology to form a new joint venture to achieve rapid expansion worldwide. In cooperation with Singaporean companies, China Science and Technology has also built a 20,000 m2 plant plant to provide Singapore with state-of-the-art indoor plant plant equipment and planting technology. Regarding the outlook for the future, Li Shaohua said,
"At present, the main cost of plant factories is labor and power consumption, and as labor costs rise, international vegetable prices are likely to continue to rise, and we will increase the level of mechanization and intelligence to further reduce costs." ”
