From 65438 to 0935, Hou Guangjiong, as a representative of the Soil Research Office of the Central Geological Survey, attended the Third International Conference on Soil Science held in Oxford, England, together with Deng Zhiyi and Zhang Naifeng, and read a paper. For the first time, he made a scientific discussion on the occurrence and hierarchical morphology of paddy soil, especially the relationship between hierarchical morphology and productivity. A variety of paddy soil specimens were also exhibited at the meeting, which systematically showed the research results of paddy soil in China and attracted the attention of participating scientists. After the meeting, Hou Guangjiong was invited by representatives from the Soviet Union, the United States, Germany, France, Britain, Italy, Hungary, the Netherlands, Sweden, etc. 10, and was sponsored by the China Education Foundation to conduct visits and cooperative research in various countries. Hou Guangjiong took "What's the difference between the soil in China and the soil in Europe?" And did research abroad for three years. In Sweden, he wrote a paper on the law of soil colloidal activity, and in the Soviet Union, he wrote a paper on the relationship between red soil composition and tea quality.
During his stay in War of Resistance against Japanese Aggression, limited by the research conditions, some of his methods of studying agricultural soil were actually established in China. The daughter helps to collect specimens and the wife helps to test them. The first successful "soil viscosity and toughness determination method" can be conveniently used to determine the properties of soil mineral colloids, which has attracted the attention of colleagues at home and abroad.
From 65438 to 0946, Hou Guangjiong transferred to Sichuan University as a professor, giving lectures on soil fertilizer science, soil chemistry, soil geography and other courses. He is conscientious and responsible in teaching, implements heuristic teaching, and often organizes students to conduct academic discussions, field trips and scientific research. During this period, I cooperated with young teachers to write three papers, namely, the relationship between soil nutrient adsorption and soil viscoelasticity, the identification of soil characteristics by viscoelasticity curve, and the determination of viscoelasticity curve, which were published in the Proceedings of the Fourth International Congress on Soil Science.
After the founding of People's Republic of China (PRC), Hou Guangjiong was invited to attend the first national conference on soil and fertilizer. Comrade Zhu De's call that "soil science must serve agricultural production" left a deep impression on him, and also strengthened his belief that the development of soil science in China should go its own way. 1952 after the adjustment of departments, Southwest Agricultural College was established with Hou Guangjiong as professor. In order to make soil science serve agricultural planning and agricultural production more closely, he undertook the investigation of rubber suitable forest land in Yunnan; Soil surveys in Minjiang River, Tuojiang River, Fujiang River and Jialing River basins in the upper reaches of the Yangtze River, as well as the first and second national soil surveys and agricultural soil zoning in southwest China. While completing these tasks, I wrote "Study on Soil Viscosity and Toughness in China", which was read at the Hungarian National Soil Society, translated into Russian, and reprinted in the journal Soil Science of the former Soviet Union, which aroused the condemnation of foreign experts. The classification and zoning of purple soil in Sichuan basin was written as a paper at the sixth international conference on soil science held in Paris. Write a paper "Study on Evaluating Soil Fertility by Using Soil Layer" and read it out at the 8th International Congress of Soil Science held in Romania. Hou Guangjiong believes that solving the problems in agricultural production will certainly promote the development of soil science.
1956, Hou guangjiong joined China * * * production party. He used to be the director of Chongqing Soil Laboratory of China Academy of Sciences, and devoted himself to studying purple soil. 1960 put forward the viewpoint of "agricultural soil physiology". During the Cultural Revolution, although Hou Guangjiong was in trouble, his wife, who had been ill in bed for a long time, died unfortunately. His family and spiritual experience did not shake his determination to continue studying agricultural soil. From 1973 to 18 years, he has been going deep into the vast rural areas, studying the application of soil science theory in Jianyang Town, Sichuan Province and Xiangling District, Changning County, and putting forward the techniques of "big nest cultivation" in dry land and "natural no-tillage" in winter paddy field. After extensive promotion, the effect of increasing production is obvious, which is valued by the majority of scientific and technological workers and welcomed by farmers.
Hou Guangjiong has been engaged in agricultural education and soil science research for decades. He is diligent in thinking, dare to innovate, and love the motherland and science. 1955 was selected into the Biology Department of China Academy of Sciences. Elected as the first, second, third, fifth, sixth and seventh NPC deputies. 1 May 19861day was awarded the National Labor Medal, and 1989 was awarded the honorary title of National Model Worker in recognition of its contribution to the development of soil science in China.
Soil scientist. Shanghai Jinshan people. 1928 graduated from agrochemical department of Beijing Agricultural University. Professor of Southwest Agricultural University and Director of Natural No-tillage Research Institute. After 60 years of teaching and scientific research in soil science, the fact of daily cycle change of "light-fertilizer balance" was found in the study of soil fertility and soil geography, thus opening up a new field of soil colloid thermodynamics; By the end of 1986, the new technology of natural no-tillage in paddy field had been popularized in 1988, and the yield increase rate exceeded 15%. In order to meet the needs of soil fertility research, soil colloid physics-soil viscosity-toughness ratio and viscosity-toughness curve were established, and soil colloid thermodynamics+combined with pH were used to determine the soil fertility classification system, which provided scientific basis for making land use planning in China. 1955 was elected as a member of China Academy of Sciences.
