The Research On Ni Dashu's Scientific And Technological Achievement And Its Thought

As we all know, China is a large agricultural country, the development of agriculture has much relation with the national economy and people's lives. Fisheries, as a fundamental ministry of agriculture, its development will have a direct impact on the development of agriculture. In China's long history of 5,000 years, the development of fishery has a decisive position. However, looking back the history of the development of the fishery, we can see that the development has been slow in the long-term, especially before modern China, the development of the fishery had no science to speak of. With the development of technology and the enhancement of overall national strength, the government puts a great deal of effort into the development of fishery, and the fishery has made remarkable progress. The fishery science and technology plays a critical role in the development, and the famous expert Ni Dashu plays a key role as well. Ni Dashu was born Wuxi in Jiangsu province which is a land flowing with milk and honey, he witnessed the modern development of the fishery and the hardships of the fishermen, and determined to make contribution to the development of the fishery. In order to achieve his aspirations, Ni Dashu went abroad and did research on protistolohy in the United States, and made great achievements. After his return, subordinated to the needs of national construction, he determinedly transformed from the research of the protistolohy to the research of fishery, and dedicated all his life. He first brought science into China's fishery development, and created the first fish diseases research work station in China. At his initiative, China opened the first fish diseases course in college. He created nearly 100 species of fish disease control methods, basically solve the difficult problem of fish diseases, His outstanding contribution to the fishery development in China made him deserved to be name, the founder of the fish diseases study in China. Meanwhile, Ni Dashu has also committed to the research of output which troubled the development of fishery, painstakingly developed the scientific methods of improving the fishery output in freshwater, and has made a tremendous contribution to the improvement of the pond breeding system, the traditional thinking of freshwater fishing and so on. Engaged in the practice of the fishery, Ni Dashu created the internationally known "rice and fish culture" , and brought China' s traditional fishing on the rice fields to a new level, thus made inestimable contributions to enhance the output and quality of China's rice and fish.This paper has three parts, based on the compressive study of Ni Dashu' s academic articles and treatises, mainly reflects that Ni Dashu dedicated himself to serve the motherland and initially develop China' s fishery, and reviews his great feats.Partâ… : review the course that Ni Dashu developed China' s fishery, who changed from the study of the protistolohy to the fish diseases; from the general freshwater fish breeding to create of rice and fish culture, thereby show up the glorious technology course during his life.Partâ…¡: From two aspects review Ni Dashu' s technological achievements on the development of the Chinese fishery , including developing the fish breeding technology in freshwater and initiating fish diseases research in china.Partâ…¢: assess Ni Dashu 's value and significance on the development of fishery science and technology ,including his noble character of firmly inspiring to serve the motherland' s cause, the enormous economic and ecological benefits brought by his rice fish symbiotic theory, the theoretical significance that science and technology as the primary productive force have for the development of fishery , the social significance for today's fishery development of Ni Dashu 's thought that theory needs to be related with the practice, and so on.
