摘　　要：以广西10个马铃薯品种为研究对象,比较常规施肥和减施肥20%条件下各马铃薯的株高、茎粗、产量、单株结薯数、商品薯率等农艺性状以及蛋白质、淀粉含量等品质性状。结果表明,减施肥20%条件下,各马铃薯品种的株高、茎粗、地上部鲜重和产量受到抑制,其中,靖薯6号和陇薯7号减产高达35%以上,丽薯6号和03-3-2减产28%左右,12号、桂农薯1号、云薯107和会薯8号减产15%左右,会薯16号和费乌瑞它减产10%左右。12号和桂农薯1号在减肥条件下,产量最高,品质影响较小,更适合广西地区减施肥条件种植。This study took 10 potato varieties in Guangxi as the research object,and compared the agronomic characters of each potato,such as plant height,stem diameter,yield,number of tubers per plant,commercial potato rate and protein content,starch content and other variety characters under the condition of conventional fertilization and 20%reduction of fertilization.The plant height,stem diameter,fresh weight above ground and yield of all potato varieties were inhibited under the condition of 20%reduction in fertilization.Among them,Jingshu 6 and Longshu 7 reduced their yields more than 35%,Lishu 6 and 03-3-2 by about 28%,No.12,Guinongshu 1,Yunshu 107 and Huishu 8 by about 15%,and Huishu 16 and Feiwuruita by about 10%.No.12 and Guinongshu 1 had the higher yield under the condition of reducing fertilizer,and were more suitable for planting under the condition of reducing fertilizer in Guangxi.
