Eight years of scientific research "bloom and bear fruit", a boletus edulis sold for ten million yuan The
transfer of the results and the transferee each received a million bonus
The delicious and nutritious bolete, due to its unique growth environment and the mysterious germination mechanism of underground hyphae, has long been a problem in artificial breeding.
In the beautiful Xishuangbanna of Yunnan, a group of dedicated agricultural science and technology workers have not only successfully bred a kind of dark brown net-stalked bolete, which is popular on the online shopping platform for fresh food and praised by the public, and obtained a number of patents. The results have been sold for a big price, and the company has a "unique skill" to grow and develop, and it also provides a successful model for the development of the green food industry that Yunnan is vigorously developing.
On November 1, Yunnan Provincial Department of Science and Technology, the scientific research team and the relevant persons in charge of the enterprise introduced the transfer of this achievement to the reporter of Science and Technology Daily.
Built the world's only factory cultivation research and development production base
Dark brown reticulate boletus, commonly known as black boletus, is distributed in Yunnan, Sichuan, Guangxi and Hainan in China; it is distributed in Thailand and Sri Lanka, Vietnam, Indonesia, Brazil, Mexico, etc. abroad.
It is large in size, delicious in taste, and rich in nutritional value. It is one of the most expensive edible mushrooms that are commonly eaten.
"In the 8 years from 2005 to 2013, after unremitting efforts and exploration, we finally developed excellent strain breeding methods, liquid strain cultivation methods, and methods for artificial cultivation of Boletus edulis in mushroom houses." Yunnan Province Researcher Ni Shubang, deputy director of the Institute of Tropical Crop Science, said.
This series of research obtained 3 authorized invention patents in 2010, 2011 and 2013.
"For a long time, Yunnan has lacked scientific and technological innovation resources, high-level, and few transformable scientific and technological achievements. While grasping the scientific research institutes, universities, and scientific and technological enterprises in the province, we should open up new sources and import scientific and technological innovation resources and scientific and technological achievements into our work. The most important of all.” Dong Baotong, Secretary of the Party Leadership Group and Director of the Yunnan Provincial Department of Science and Technology, told reporters.
In 2013, Jinghong Hongzhen Agricultural Technology Co., Ltd., the predecessor of Hongzhen Biotechnology Group (hereinafter referred to as Hongzhen Bio) was established, and focused on the artificial domestication, cultivation and sustainability of rare wild edible fungi in Yunnan Province through scientific and technological means development of.
They invested 60 million yuan to build a preliminary research and development base for industrial cultivation of black bolete that cultivates 5,000 bottles a day; in October 2015, the factory cultivation of bottle planting mode was successful, with a fruiting rate of 90% and an average of fresh cattle per bottle. 90 grams of liver mushrooms; in 2016, 4 invention patents related to Boletus edulis were authorized.
"After 8 years of arduous exploration and unremitting efforts, by 2019, we will invest 220 million yuan to complete the research and development of a complete set of technology systems for artificial domestication, variety improvement, germplasm preservation, improved species cultivation and factory cultivation of wild boletus edulis. , The world’s only black boletus strain preservation and factory cultivation research and development, production base has been built.” said Ji Kaiping, deputy general manager and technical director of Hongzhen Biotechnology, the base produces 4 tons of fresh boletus per day.
“In January 2019, Hongzhen Biotechnology purchased 3 invention patents of Boletus edulis from Yunnan Institute of Tropical Crop Science for 10 million yuan. The current output is stable and the technology is mature, laying a strong foundation for expansion and industrialization. Strong technical support." Ji Kaiping said that at the end of that year, they completed the research and development of a complete set of technology systems for the collection of black boletus, breeding of fine varieties, and industrial cultivation.
"As the transferor and transferee of the scientific and technological achievements of artificially cultivated boletus, in accordance with the implementation opinions of Yunnan Province on financial support and promotion of the transformation of scientific and technological achievements, Yunnan Provincial Institute of Tropical Crop Science and Jinghong Hongzhen Agricultural Technology Co., Ltd. respectively won 100 The 10,000 yuan financial science and technology fund award is supplemented.” said Gao Jun, deputy director of the Yunnan Provincial Science and Technology Department.
In March 2020, Hongzhen Biotech's factory cultivation base for cultivating 200,000 bottles of fresh boletus per day and a daily output of 20 tons of fresh boletus began construction in Damenglong Town, Jinghong City, and will be completed and put into use in 2022.
It is estimated that in early 2023, 26 tons of fresh porcini mushrooms will be supplied to people's tables every day.
In the next few years, it will reach a daily production capacity of 100 tons.
An achievement transformation brings social and ecological double benefits
“The wild bolete that originally only grows in summer can grow in greenhouse mushroom houses and economic forests in subtropical climates throughout the year.” Ni Shubang proudly said that through the transformation of the results, the dark brown reticulate boletus has also become In recent years, the world's edible mushroom industry has developed the only new species that can be cultivated in factories, and it is the only species in the edible bolete family that can be cultivated artificially.
The development of the boletus industry has turned hundreds of thousands of tons of crop straws and rubber wood chips produced in Xishuangbanna and Jinghong every year into treasures, which have become raw materials for cultivation, providing a large number of employment opportunities for the society and helping to fight poverty.
After the mushrooms are harvested, the boletus edulis can be used as organic fertilizer to improve the soil and be used for biomimetic cultivation under economic forests such as grapefruit, phoenix tree, loquat and peach trees, harvesting forest fruits, and realizing multiple benefits of bacteria, fruits and forest trees.
"This three-dimensional cultivation model is a new model of harmony between the development of the edible fungus industry, the utilization of fruit forest resources, and the increase of farmers’ income. It is conducive to promoting agricultural production, increasing farmers’ income, improving the agricultural ecological environment, and achieving sustainable agricultural development. It is of great significance to get rid of poverty and become rich," said Yan San, director of the Science and Technology Bureau of Xishuangbanna Prefecture, Yunnan Province.
Dong Baotong introduced to reporters that in recent years, Yunnan Province has fully implemented the subsidy policies for technology transactions, service organizations, and newly established enterprises for the transfer and transformation of scientific and technological achievements.
Government procurement, research and development subsidies, post-R&D subsidies, release of industrial technology guidance catalogs, demonstration and promotion, etc., shall be adopted to provide financial support for the transformation of scientific and technological achievements.
In 2020, the province has arranged financial awards of 28.3 million yuan for 13 projects with significant achievements in the transformation of scientific and technological achievements; and arranged financial funds of 6.2 million yuan for 11 universities and research institutes that have established institutions for the transformation of scientific and technological achievements.
