The life of the character
1929165438+1October 17. Liu Jun was born in Qingshuping Township, Shuangfeng County, Loudi City, Hunan Province. When I was a child, the whole family relied on his father to do some small business, and his mother knitted hats by hand.
1937, parents took Liu Jun and his younger siblings to Wugang county, and when they graduated from primary school, they were admitted to Hunan private Dongting Middle School (now No.2 Middle School in Wugang City).
At the beginning of 1945, all the teachers and students of Dongting middle school fled to Huitong mountain area at the junction of Hunan and Guizhou. Liu Jun insists on studying under kerosene lamps for more than three hours every day.
1948, admitted to Hunan Normal University for Nationalities.
1949, transferred to the biology department of Hunan University.
1953, graduated from the biology department of Hunan University, and was assigned to the biology department of Hunan Normal University as a teaching assistant and department secretary.
1956, recommended by Dong, then director of biology department of Hunan Normal University, was sent to the Institute of Experimental Biology of China Academy of Sciences to study experimental embryology, under the guidance of Zhuang Xiaohui and Zhu Xian. Since then, he has stepped into the door of fish research.
1956- 1958, majoring in experimental embryology (developmental biology), Institute of Experimental Biology, China Academy of Sciences.
1958, I returned to the biology department of Hunan Normal University from Chinese Academy of Sciences, and met with the "Great Leap Forward" and went to Changsha Comprehensive Farm to "open a school".
1982, joined the China * * * production party.
1995, elected as an academician of China Academy of Engineering.
1On April 8, 1998, Xiangyun Industrial Co., Ltd. was established in Hunan Normal University with the mission of promoting the national "863" high-tech pilot development projects "Xiangyun crucian carp" and "Xiangyun carp".
1999165438+1On October 26th, the lecture hall of the Biology Building of Hunan Normal University held a meeting to celebrate the 70th birthday of Academician Liu Yun.
In 2000, the Key Laboratory of Histology and Developmental Biology in protein, Hunan Province, chaired by Professor Liu Jun and Professor Liang Songping, was officially approved to be included in the key laboratory construction plan of the Ministry of Education.
In 2008, 654.38 million yuan was donated to establish the Liu Yun Scholarship.
2015 65438+1October 2 1 died in Changsha at 5: 07 am at the age of 86.
Major achievements
achievements in scientific research
In theory, Liu Jun has established the systematic reproductive physiology of the main cultured fish (mainly the four major fish), soft-shelled turtle (soft-shelled turtle) and frog (edible) in China, and developed the technical system of artificial breeding and aquatic economic market of cultured fish in practice. Using the comprehensive technology of cell engineering and sexual hybridization, the first tetraploid fish population with stable genetic traits and natural reproduction was established at home and abroad, and high-quality triploid crucian carp and triploid carp were successfully cultivated.
When Liu Jun studied the fertilized cells of herring (female) and Megalobrama amblycephala (male), he found for the first time that the distant hybridization of fish had a process of fertilization cytology, thus denying the view that some foreign experts thought that distant hybridization of fish could only activate eggs and limit fertility. This theory is called "Liu Theorem" by the international fish research community. In the study of crucian carp hybridization, Liu Jun found that the male part was fertile, bred into F 1-F 10 generation, and cultivated tetraploid population with stable genetic traits, which overthrew the view that the male of crucian carp hybrid F generation was completely sterile at home and abroad for the first time. These findings are helpful to clarify academic right and wrong, and to develop reproductive physiology and breeding of fish and aquatic economic animals.
From 1959 to 1963, Liu Yun devoted himself to the research on the reproductive physiology and artificial propagation technology of the four major fishes, and the researchers of the cooperative unit successfully studied the natural spawning and fertilization of grass carp at the earliest. From 65438 to 0960, Liu Jun and his colleagues completed the research project of "Artificial propagation and technical popularization and application of domestic fish such as grass carp". 1September, 1995, the project "artificial propagation and self-spawning technology of herring" solved the problem that ovulation of female fish is not synchronized with sperm ovulation of male fish, and since then, the culture of four major fish in China has entered full artificial propagation.
Up to 20 15 and 1, Liu Jun has published more than 100 papers in China and other domestic and foreign journals. Writing monograph "Reproductive Physiology of Cultured Fish in China".
By the end of 20 15 and 1, Liu Yun's related research achievements had won more than 20 national, provincial and ministerial awards, such as the second prize of national scientific and technological progress, the first prize of State Education Commission and the first prize of Hunan scientific and technological progress. Obtained more than 30 national invention patents.
personnel training
Liu Jun thinks: "It's not only high-level, not only books, but also reality. Practice is the objective criterion for testing truth. Realism is the driving force for development and progress. "
Liu Jun has trained more than 200 doctoral and master students for the country in his life, and many students have been promoted to professors and doctoral supervisors in China.
Honor recognition
social service
Personal life
Liu Jun's wife Hu Yunjin is a teacher of the Academy of Life Sciences. 1959, when Liu Yun's eldest daughter was born, he was studying the artificial propagation of silver carp, so he was named Liu Baizhu. 1960, when his second son was born, he was exploring grass carp, also known as pomfret, and he named his second son Liu pomfret. 1962, when the youngest son was born, he was named Liu Shaojun at the request of his mother that "the whole family can't be fish".
Liu Yun loves sports. He liked swimming in primary school. After entering middle school, he likes running, climbing mountains and playing ball games. At that time, places of interest near Wufeng County, such as Yunshan, Nanshanzhai, Dongta, etc., visited him every year, leaving early and returning late, and often took Qibali Mountain Road one day.
Personality assessment
He (Liu Jun) is a real master. He devoted his life to making people eat fish and eat good fish. He is a respectable elder who loves life as much as a child and is amiable. He devoted his whole life to the study of fish reproduction, and was the main founder of the artificial propagation of the "four big fish" in China, as well as the basic theoretical research of the "four big fish" in China. (Hunan Daily Review)
Academician Liu Jun devoted his life to fishery research in China. After half a century of hard research and struggle, he presided over the development of the world's first amphipathic tetraploid fish strain. A number of important scientific research achievements, such as "artificial propagation and technical popularization and application of domestic fish" presided over by him, have been popularized and applied throughout the country, resulting in remarkable economic and social benefits.
