• 英文摘要： Proceedings of a Symposium on the Causes of Low Yield of the Second Crop Rice in Taiwan and the Measures for Improvement, co-sponsored by the National Science Council of the Republic of China and Taiwan Agricultural Research Institute, and held at the Institute in Wufeng, Taichung, Taiwan from 7-8 June, 1978 will be published by the National Science Council. As the acreage of rice production is 30% higher, but the yield per unit area is 25% lower, in the second than in the first crop in Taiwan, a further advance in rice productivity in the second crop season would be essential for the increasing dependence by an expanding population on relatively limited cropland. The Symposium, attended by experts from Academia Sinica, Council for Agricultural Planning and Development, National Taiwan University, National Chung-Hsing University, Taiwan Agricultural Research Institute and many District Agricultural Improvement Stations, was characterized by the presentation of research papers and a joint proposal of a guideline for future studies. Dr. T. T. Chang, breeder of the International Rice Research Institute in Philippines, was also invited to speak on the application of genetic resources on rice breeding programs. The attendence of over 150 delegates from 26 agricultural research organizations all over the island also marked the great success of the Symposium. The oncoming 'Proceedings of a Symposium on the Causes of Low Yield of the Second Crop Rice in Taiwan and the Measures for Improvement' deals with rice production in many aspects. Contents of this Proceedings include the present status of rice production (3 papers), environmental impacts on yield (3 papers), rice physiology (6 papers), soil and fertilizer studies (4 papers), diseases and insect pests (2 papers), selection method of rice breeding (2 papers), and improvement of the second rice crop (2 papers). It also included a general discussion session. By summarizing the many suggestions provided by the attending delegates, a practical guideline for future studies aimed at improving the second rice crop in Taiwan had been drawn. The Proceedings will contribute valuable informations to rice researchers as well as to rice production in the future.
