Peng, a famous plant virus expert, is from Panyu, Guangdong, 1925. 1947 graduated from the Department of Agricultural Chemistry, Central University. 65438-0948 worked as a teaching assistant in the Department of Soil Science in Peking University, and as a technical assistant in the preparatory office of Shanghai Institute of Medical Sciences, China Academy of Sciences. 1949, Assistant Research Fellow, Institute of Physiology and Biochemistry, China Academy of Sciences, 1953 joined China. 196 1, associate researcher and researcher, Shanghai Institute of Biochemistry, Chinese Academy of Sciences. 1972, the institute reorganized the virus group, and he served as the team leader.
Peng has been engaged in biochemical research for 30 years, and has made outstanding contributions to the research of enzymes, protein and plant viruses, especially the research and prevention of plant viruses. After being the team leader, he conducted extensive research on viruses in grain crops and cash crops, and solved the problems of virus identification, virus plasmid separation and purification, and preparation of control serum, making this group an important force in plant virus research in China. Its research scope is wide, including citrus Huanglongbing, mulberry dwarf disease, wheat dwarf disease, rice dwarf disease, yellow dwarf disease, barley soil-borne mosaic disease, sweet potato dwarf disease, Hami melon mosaic disease and so on. Especially in the international research on the unsolved pathogen of citrus Huanglongbing, the linear virus was isolated and purified, the existence of bacteroides was observed, and the fine structure of the plasmid of the linear virus was discovered.
Peng's attachment to Xinjiang's scientific research is an accidental opportunity. 1956, participated in the comprehensive scientific desert investigation of China Academy of Sciences and went to Xinjiang for the first time, and offered to support frontier science. 1962 Peng and his colleague Chen Shanchuan were ordered to build the Xinjiang branch of the Chinese Academy of Sciences. After Peng became the president of the branch, he made great efforts to develop into a branch with four research institutes of physics, chemistry, geography and biological soil and desert, and trained a large number of scientific researchers for Xinjiang. In 1963, Peng was rated as a "scientific model".
Xinjiang is dry with little rain, windy and dusty, and plant disasters are very serious. Peng led the staff of the Institute of Chemistry to conduct in-depth field investigation, collect disease samples and research data, and went back to the laboratory for repeated experiments, and successively isolated and purified viruses that harmed corn, wheat, oats, melons, large rainflies, apples, etc., which opened up a broad situation for the study of plant viruses in Xinjiang. Guo Moruo, president of China Academy of Sciences, once wrote a poem praising him: "He is energetic, patriotic, brave and good at fighting, hardworking and complaining, and dares to turn Gobi into fertile land."
Lop Nur is located in Lop Nur depression on the eastern edge of Taklimakan Desert in southern Xinjiang. Since ancient times, it has been a famous "mysterious place" at home and abroad? There were human activities four thousand years ago, and Loulan was once a rich ancient country in the Han and Tang Dynasties. Over time, how can it become an uninhabited wasteland? In the past century, some Chinese and foreign people with lofty ideals have tried to break into it and uncover the mystery. Peng, who is keen on scientific investigation and development of frontier resources, is one of them.
Peng Yu 1964 broke into Lop Nur for the first time and found that there were rich salts and various wild animals and plants, which made him extremely surprised and determined to uncover the mystery of the treasure. Therefore, it is planned to cross Lop Nur basin once from north to south and once from east to west, and then conduct an investigation around the lake basin. According to the information obtained from his many explorations, he came to the conclusion that a large amount of potassium salt has accumulated in this stratum, and there may be precious resources such as rare metals and heavy water. It is ready to open a passage to conduct a comprehensive investigation of its geography, flora and fauna, hydrogeology, soil and archaeology, and thoroughly uncover the mystery of the motherland for thousands of years. /kloc-in the winter of 0/979, he led a reconnaissance team to re-enter and conducted reconnaissance for more than 20 days. After he came back, he made a scientific investigation plan for Lop Nur sag. At the beginning of May 1980, Peng Yiran, then 55, led a team to inspect again, braved the high temperature and dry heat of 45℃ in the desert area in early summer, and finally successfully crossed the center of Lop Nur basin from north to south at the end of May, creating the miracle of uncovering the mystery of Lop Nur for the first time, exploring the face of its natural environment and opening the door for future comprehensive investigation.
It turns out that Peng plans to visit the lower reaches of Shule River from the southern edge of the lake basin, and then bypass the edge of the lake basin and return to the campsite on the northern shore of the lake basin. However, due to the serious water shortage of the scientific research team, it is in urgent need of supplementation. Regardless of his personal safety, he went out to look for water alone on the evening of June 26, and as a result, he lost his way in the vast sand sea and failed to come back. After being searched everywhere by his colleagues, he unfortunately disappeared and suffered greatly, and sacrificed his precious life for the scientific investigation of the motherland.
After Peng's death, the State Council recognized him as an "outstanding scientist" and a "revolutionary martyr".
