调查福建省东南沿海地区23个县市，从1975-2012年每5年甘薯的栽培面积、总产量、品种和栽培技术等变化，研究分析表明，30多年来福建省沿海地区甘薯种植面积虽有一定的下降，但仍保持较大面积，占福建省甘薯种植面积的比例有所上升。期间，甘薯单位产量有较大的提高，但面积和总产量的变化趋势不同于同期我国整体甘薯产业变化情况。本研究认为该区域的甘薯品种更新、栽培技术提高、消费习惯和传统甘薯文化的综合作用等是产生这一趋势的主要原因，为也提出了建立优质种苗基地、推广优质新品种等促进甘薯区域发展的建议。%In order to raising the level of sweet potato industry in Fujian province , the sweet potato in Fujian province′s coastal area has been analyzed in the paper .The analysis was based on the statistic data from twenty-there counties and cities in the province′s southeaster coastal areas ,including planting areas ,yield ,cultivated varieties and cultivation techniques changes every five years from 1975 to 2012. The result showed planting areas had slowly declined during 30 years but held superior area in those regions in 2012 . But unit productions had increased in this period .Planting areas and unit productions change trend differ contemporaneous trend in china .We believe variety renewal ,improving in cultivation techniques ,spending habits of sweet-potato and traditional sweet-potato culture in this area are the mainly reason of change trend described above . Finally , suggests for the improvement recommendations are made ,including constructing high-quality seed tubers base ,strengthening sweet potato breeding and new cultivation techniques research and demonstration .
