《甘薯可持续生产技术与粮食能源安全：第三届中日韩甘薯学术讨论会论文集（英文版）》主要内容Sweetpotato is an important food， forage，industrial raw material crop， and today it is es-pecially attached importance as a new energy resource crop. China，Japan，and Korea arethe worlds main producers of sweetpotato，and the three countries have led the world inmany aspects of this crop such as breeding， cultivation， biotechnology， and processing.Thus，China-Japan-Korea Workshop on Sweetpotato is held at two-year intervals to ex-change the research results and experiences and to promote the research and production ofthis crop.

Organized jointly by，Sweetpotato Specialty Committee， Crop Science Society of China，China Agricultural University，Xuzhou Sweetpotato Research Center，Beijing Daxing District Government & Panggezhuang Town Government.
