Engineering specialty is one of the pioneers of fruit storage and preservation in China.

Li Peiwen, a natural character. 1906 12 16 was born in Liaoshen Village, Daposhan Market, Cangwu County, Guangxi. His father is Mr. Li, the late famous patriotic democrat and vice chairman of People's Republic of China (PRC). He lived in the countryside when he was young, and his hometown was rich in fruits such as Shatian pomelo and litchi, so he had a perceptual knowledge of fruit trees since he was a child. 192 1 studied at Nanhai middle school in Guangzhou, and then transferred to the high school affiliated to Guangdong Normal University. 1925 was admitted to the preparatory course of Sun Yat-sen University. From 65438 to 0927, he went to study in the United States, studied at Purdue University and the University of Iowa successively, and then transferred to Cornell University to specialize in fruit tree science, and studied citrus cultivation at the University of California, and obtained a master of science degree from 65438 to 0932. 1933 After returning to China, he taught at Zhejiang University. 1935 was hired by Lingnan University as a professor in the Department of Horticulture of the Agricultural College, which was later changed to the Department of Plant Production, with Li Peiwen as the dean. During the period of 1938, the bonfire in War of Resistance against Japanese Aggression spread to Guangzhou, and Lingnan University moved to Hong Kong. 194 1 In the autumn of, Gu Guifen, former dean of the Agricultural College of Lingnan University, passed away, and Li Peiwen took over as dean. Later, because the Japanese invaders invaded Hong Kong, the Agricultural College of Lingnan University moved to Shi Ping, a mountainous area in northern Guangdong. At that time, Japanese planes bombed everywhere. Li Peiwen put his career first, resolutely left his wife and daughter behind, and went to northern Guangdong alone to preside over the work of the Agricultural College, insisting on teaching with the faculty. Many famous professors have been influenced by it and applied for teaching. In the late period of War of Resistance against Japanese Aggression, Japanese invaders invaded northern Guangdong, and Shi Ping was threatened. Teachers and students of Agricultural College headed by Li Peiwen have been wandering in the mountainous areas, but they still insist on teaching and scientific research. Under the influence of his dedication, the teachers and students of the whole hospital were United as one, sharing weal and woe, and finally passed the crisis and ushered in the victory of War of Resistance against Japanese Aggression. Up to now, whenever Lingnan University alumni get together and recall the hard journey of that year, Shi Ping alumni are all proud of it and miss Li Peiwen even more.

After 1945, Lingnan University moved back to Guangzhou, and Li Peiwen was still the dean of the Agricultural College, devoted to resuming teaching and scientific research. He is particularly concerned about the development of citrus in China, and thinks that the quality of citrus in Chaozhou, Guangdong Province is as good as that of foreign varieties. Unfortunately, due to backward cultivation techniques and fatal Huanglong disease, it is declining day by day. Before War of Resistance against Japanese Aggression, he was determined to revitalize Guangdong's citrus industry. First, he conducted an investigation on improving the mother tree and an experiment on pest control. /kloc-0 In the winter of 937, a citrus breeding laboratory was established in Mianchao Township, Chao 'an County, which is rich in citrus. Later, with the support of Chaoshan industrialist Zheng Shouzhi, Chaoshan Citrus Experimental Field was established in Chaoyang County in the spring of 1939. On the one hand, American experts such as Lin Kongxiang, Zheng Tianxi and Huang Changxian are invited to return to China for research work; On the one hand, with the help of Wu, Wang Haozhen, Xie Huang and Chen Huaren, a large number of excellent mother plants were screened out for breeding. This work continued until the establishment of People's Republic of China (PRC), which laid a good foundation for the development of citrus industry in Chaoshan and Boluoyang villages. He has been obsessed with the prevention and treatment of Huanglongbing, which harms citrus in Guangdong and Guangxi, and constantly seeks solutions. After the 1950s, although Li Peiwen turned to the study of fruit storage because of his work needs, he still supported the work of Lin Kongxiang, an expert on Huanglongbing, with great enthusiasm, and made efforts to create conditions for him, winning Lin Kongxiang's admiration and taking Li Peiwen as his mentor.

Li Peiwen deeply felt that domestic agriculture was backward, and thought that the ploughing and harrowing method adopted by China for thousands of years should be mechanized as soon as possible, so as to increase production in a large area. 1948 During May, he took advantage of his position as the dean of the Agricultural College of Lingnan University and managed to win the position of director of Guangdong Agricultural Reclamation Office from Guangzhou Office of the United Nations Relief and Rehabilitation Administration, thus establishing a tractor demonstration farm in Ma 'anling, Dongguan County, Guangdong Province. 1In September, 949, the Nanjing National Government ordered him to transfer all materials to Hainan Island when he left the mainland. Li Peiwen has long been dissatisfied with the rule of the Kuomintang. In order to keep rare equipment, he refused to carry out orders and secretly instructed his men to dismantle tires and important parts of automobiles and agricultural machinery, so that these materials could not be transferred. This angered the Kuomintang authorities and suddenly detained him at a meeting. Thanks to the help of Lingnan University and social celebrities, as well as his high reputation in academia and society, Kuomintang agents dare not do it.

After the founding of People's Republic of China (PRC), he devoted himself to the construction of the motherland with the passion of gaining new life. During the period of 1952, colleges and universities across the country adjusted their departments. He led the teachers and students of the Agricultural College of Lingnan University, merged with the former Agricultural College of Sun Yat-sen University and the Animal Husbandry Department of Guangxi University to form South China Agricultural College (now South China Agricultural University). He served as vice president and vice president. After the adjustment of the department, due to the needs of work, it turned to the research and teaching of postharvest treatment of fruits and vegetables and storage and preservation of fruits. He took the lead in transporting tropical and subtropical fruits from the south to the north and selling them to the Soviet Union and eastern European countries. 65438-0978 edited the textbook "Fruit Storage and Processing". In addition to his busy teaching and scientific research work, he is also in charge of the school's logistics work and works quietly to revitalize the agricultural education in the motherland. Li Peiwen worked hard all his life and died in 1985.

During his stay in the United States, Li Peiwen has noticed the importance of fruit storage and preservation. He witnessed that China's fruit storage technology is backward, and fruit farmers all over the country only rely on ancestral experience to preserve fruits, lacking scientific basis. After returning to China to teach, he began to study citrus storage, and published two papers on citrus storage in Lingnan Agricultural Journal 1936 and 1942. This is an earlier research report on fruit storage in China. From 65438 to 0953, he made many achievements in the research of citrus storage and preservation, and put forward the suitable storage temperature of several main citrus varieties (sweet orange, banana orange, ponkan, etc.). ) In Guangdong, the characteristics of low temperature tolerance of citrus fruits were pointed out, and some laws of "edema disease" of citrus fruits in cold storage were published and confirmed. Fruit companies in Guangzhou, Beijing, Shanghai and Tianjin have adopted this research result to avoid the occurrence of "edema" disease of citrus fruits during storage. For this reason, this achievement won the 1975 fourth prize of Guangdong Scientific and Technological Achievements. 1989, the Ministry of Agriculture awarded the third prize for scientific and technological progress. During the "Sixth Five-Year Plan" period, the Postharvest Physiology Laboratory, presided over by Li Peiwen, undertook the national key project "Fruit Storage and Preservation", studied the chilling injury of citrus fruits during storage from another angle, and put forward that the occurrence of sweet orange brown spot was caused by inappropriate low temperature and its stimulated endogenous ethylene; The methods of pretreatment before storage to prevent diseases were also studied. At the appraisal meeting hosted by the Ministry of Commerce, this achievement was rated as the first in the country.

In the early 1950s, the Ministry of Foreign Trade and the Ministry of Commerce of China jointly proposed to transport goods from the south to the north and export them to the Soviet Union. After accepting the task, he cooperated with Guangdong Fruit and Vegetable Company. First of all, he chose bananas and oranges as export targets, personally held technical training courses in fruit producing areas, and participated in post-harvest treatment such as fruit harvesting and packaging. Li Peiwen has applied its technical achievements in storage and preservation for many years to production, successfully transported bananas and oranges to the Soviet Union and eastern European countries, and created a road for tropical and subtropical fruits in China to be transported to the north for export.

Li Peiwen has devoted more efforts to the storage and preservation technology of litchi, and it is his lifelong wish to transport and sell litchi which can only be stored for 2-3 days after harvest to all parts of the world. Inspired by ancient fruit farmers digging bamboo to hide fruits, he began the study of low-temperature spontaneous controlled atmosphere storage of litchi in 1950s. By 1963, litchi could be kept fresh for one month. Under his guidance, Guangdong Export Corporation exported litchi stored for one month to Hong Kong. Yangcheng Evening News also published an article entitled "Millennium Brothers Meet, Happy", expressing people's approval that litchi and longan with different maturity can be listed at the same time. However, Li Peiwen did not stop there. He went on to study a series of processing techniques such as storability, browning reasons, suitable storage temperature after harvest, and packaging forms of several main litchi varieties rich in Guangdong. In the early 1980s, the storage life finally exceeded 50 days, and the mass production storage and transportation reached 35-40 days. To this end, he won the third prize of scientific and technological progress of the Ministry of Agriculture, Animal Husbandry and Fisheries and the second prize of agricultural scientific and technological progress of Guangdong Province from 65438 to 0985.

In the early 1980s, under the guidance of Li Peiwen, his assistants and graduate students studied the relationship between flower bud differentiation and hormones in litchi, and measured the changes of various hormones during the differentiation and their effects on the differentiation. Applying exogenous hormones can effectively promote the flowering and fruiting of litchi. This achievement played an important role in overcoming the age of litchi and won the second prize of 1990 Guangdong Science and Technology Progress Award.
