Dong Wei
Dong Wei
Dong Wei, formerly known as Dong Zhankui and Dong Meijun, was born in Guanxian county (formerly Tangyi county) of Shandong Province. Born on August 21, 1923. In 1946, he graduated from the Department of animal husbandry and veterinary medicine of Northwest Agricultural University with a bachelor's degree in agriculture. In 1957, he went to the Reproductive Biology Laboratory of the all Soviet Institute of animal husbandry in Moscow, the former Soviet Union, to study animal reproduction. In 1960, he received an associate doctor's degree in biological sciences.
Life of the characters
Dong Wei was born in a businessman's family. After finishing primary school in his hometown, his father hoped that he would be able to work in agriculture and business in the future and inherit his family fortune, so he sent him to study in Jinan provincial No.1 junior high school. One year later, due to the outbreak of the Anti Japanese War and the Japanese invasion, they had to drop out of school and return to their hometown to study in private schools. In 1939, they came to Jinan again to study in Qilu senior high school. However, due to the Pacific Pearl Harbor incident, Japan and the United States declared war, so that the American church school was also taken over by the Japanese army. After four months of trekking, we finally arrived in Shaanxi. When he was in the difficult situation of no way to study and hard to find a job, Northwest University was entrusted to carry out the unified college entrance examination. He applied for the Northwest Agricultural College in Wugong County, Shaanxi Province, and was successfully admitted to the Department of animal husbandry and veterinary medicine. During his study in University, he was not only interested in natural science, but also in foreign languages, astronomy, geography and history. He chose Russian as his second foreign language, and he never stopped studying even after graduation, which laid a good language foundation for his later study in the Soviet Union. He once drew a constellation map of the sky and compiled a chronology of Chinese dynasties. Even when he was old, he still kept the habit of carrying a atlas every time he went out. His extensive knowledge and rigorous style of study have created conditions for him to advance on the road of science. Four years of college life not only enriched his knowledge of science and culture, but also aroused his admiration for great scientists. At this time, he has chosen a path of strengthening the country by science and saving the country by science. In the autumn of 1946, he successfully completed all his studies and received a bachelor's degree in agriculture. However, at that time, the KMT's political arena was dark, its economy was deteriorating, and it was pessimistic about the future of the country. It once wanted to go abroad for further study, but it was unable to do so because it could not afford it economically. Since then, he has worked in the central animal husbandry Experimental Institute and the Beiping work station. He was greatly inspired by the birth of new China and felt that his life would take a major turn with the great changes of the country. In early 1950, he was transferred to the new North China Institute of Agricultural Sciences (the predecessor of the Chinese Academy of Agricultural Sciences) in Beijing. Thus began his new journey.
In the early 1950s, horses were mainly used in service in China. With the recovery and development of national agricultural production, the number of horses needed has also increased greatly. Obviously, the promotion of artificial insemination is a good way to develop horse production. In order to do a good job in the demonstration, promotion and service of horse artificial insemination technology, Dong Wei and his colleagues set up the earliest horse artificial insemination station in Zhangbei County, Hebei Province. From 1951 to 1955, he went to Zhangbei base point every March for artificial insemination test and promotion. At that time, the living and working conditions were very difficult, but he stayed for half a year. He first used rectal examination to judge the estrus state and pregnancy diagnosis of mares, so as to accurately determine the time of insemination, reduce the number of insemination, reduce the amount of semen, and increase the conception rate of horses from the original 30% - 40% to 50% - 70%, reaching the international advanced level at that time. This technique was widely used in all horse breeding stations in China and has been used up to now.
In 1952, Dong Wei joined the China Democratic League and became a member of it. In August 1956, he was approved as a member of the Communist Party of China.
In 1956, Dong Wei was selected to study in the Soviet Union. After a year of Russian training, he entered the Reproductive Biology Laboratory of the National Institute of animal husbandry in Moscow in the winter of 1957. It was found that there was a close relationship between the fertilization rate of pig eggs and the amount of insemination. It was suggested that the amount of insemination should not be too small and the number of insemination should be twice. During his study in the Soviet Union, he published three academic papers. In November 1960, he successfully passed the thesis defense and obtained the associate doctor's degree in biological science.
In 1989, he often felt unwell and was diagnosed with pulmonary fibrosis by doctors. Since then, due to overwork, he has been sent to the hospital for treatment for many times. Whenever leaders, colleagues and students visit him, he always asks to first listen to the development of the school, college and teaching and research group, and then sigh. In the case of his serious illness, he still edited a 250000 word Chinese English animal husbandry vocabulary with amazing perseverance. As the deputy editor in chief of animal husbandry in Encyclopedia of China Agricultural volume, he personally participated in the writing of three data about livestock breeding in the volume, with a total of 10000 words. Due to his important contribution to the compilation of the book, he received an honorary certificate from the State Press and Publication Administration in December 1993. In addition, he was the editor in chief of animal reproduction in Encyclopedia of Chinese agriculture animal husbandry volume, and wrote 28 data, about 30000 words. The spiritual wealth left to posterity condenses his painstaking efforts.
At the beginning of 1994, his condition worsened. Due to the decline of lung function, he completely lost his ability to take care of himself. He had to endure great pain every step or swallow. At this time, he realized that he could not continue to work. In order to make the materials he has accumulated over the years useful, he asked his family and students to help him sort out a large number of materials and books, and donated them to the university library, the teaching and research group and his students as his last contribution to animal reproduction.
Personal contribution
He has been active in the front line of teaching since he was transferred to the animal husbandry department of Beijing Agricultural University in 1974. In 1978, he edited the unified textbook of animal husbandry in agricultural colleges and universities, which was compiled by the teachers of six agricultural colleges and universities. In 1989, he edited the revised edition, which won the national excellent textbook award issued by the State Education Commission. He also edited the "training program for postgraduates majoring in animal reproduction in National Agricultural Universities". In addition, he also opened and taught two professional required courses: the progress of livestock reproductive physiology and livestock reproductive technology for postgraduates. As there is no fixed teaching material for these two courses, he has to consult a large number of literature before each lecture, and strive to introduce the latest progress of this major at home and abroad to the students. In teaching, he also pays attention to using heuristic teaching methods to mobilize students' learning initiative. At the end of each course, students are required to write professional review articles, which not only improves their reading ability of professional English, but also exercises their comprehensive analysis and writing ability, and achieves good teaching effect. Even after he was diagnosed with pulmonary fibrosis, he still insisted on completing the teaching task with indomitable perseverance and showed his lofty moral character of loyalty to the cause of education. In 1987, his required courses for postgraduates won the excellent award of classroom teaching for Postgraduates of Beijing Agricultural University. He also attaches great importance to the cultivation of graduate students' practical ability and social work ability. In view of the general tendency of emphasizing theory over practice among graduate students, we consciously put some experimental work on the grass-roots level, which not only improves the ability of graduate students to handle and solve practical problems independently, but also gives them an opportunity to contact the society and enhance their understanding of the national conditions and sense of social responsibility. Over the years, he has trained 10 postgraduates, 6 doctoral students and 4 international students. Some of these people have become the professional and technical backbone of various units, and some are still studying abroad.
From 1979 to 1981, entrusted by the Ministry of agriculture, Dong Wei held four national training courses on livestock breeding science and technology, and trained 200 scientific and technological personnel and teachers with intermediate titles or above. It played a positive role in promoting the popularization and improvement of livestock breeding science.
In the case of heavy teaching and research tasks, he also undertook a large number of social activities for a long time, often working late into the night. From 1978 to 1991, he has been the executive director of the Chinese society of animal husbandry and veterinary medicine, participating in the decision-making of major events of the society; since 1980, he has successively served as the director of the reproductive biology branch of the Chinese society of zoology, the vice chairman and chairman of the animal reproduction Research Association of the Chinese society of animal husbandry and veterinary medicine (now known as the branch), and the senior professional title appraisal group of Beijing Higher Education Institutions (animal husbandry and veterinary medicine) He is the scientific consultant of Hebei bovine embryo transfer center and the associate editor and chief editor of Journal of animal husbandry and veterinary medicine. Under his active advocacy and organization, Animal Reproduction Research Association of animal husbandry and Veterinary Society was finally established. The establishment of the society marks a new height of animal reproduction research in China. In recent years, with the joint efforts of him and his colleagues, the annual academic seminar of the Research Association has become better and better, and the level and number of participants have been greatly improved. He was hospitalized because of illness and could not personally preside over the seminar, but he still paid great attention to the seminar. He listened to the reports of the leaders of the seminar many times in front of his bed and discussed the major issues of the development of the seminar. His conscientious spirit deeply moved many colleagues who worked with him. He played an important role in the establishment and development of the society.
Character evaluation
He always adheres to the scientific attitude of seeking truth from facts. Anyone who has contacted him will feel his serious attitude. Under the bad atmosphere of exchanging money for achievements, buying projects with money and asking for professional titles with human feelings, he always insisted on being practical
