摘　　要：选用3种类型马铃薯品种紫花白、内薯3号、坝薯10号,它们分别为早、中、晚熟和低、中、高淀粉品种,研究了底施生物有机肥、锰肥、锌肥在马铃薯上的施用效果。结果表明,不同品种、不同肥料对马铃薯产量和淀粉含量的影响差异显著,它们对产量和淀粉含量的效应为施肥>品种。其中肥料对马铃薯产量和淀粉含量的效应为生物有机肥>锰肥>锌肥;品种对马铃薯产量的效应为紫花白>坝薯10号>内薯3号,对淀粉含量的效应为坝薯10号>紫花白>内薯3号。The effects of bio-organic fertilizer, Zn fertilizer and Mn fertilizer on the output and starch contents of 3 potato varieties,which are early ripe, middle ripe and late ripe with low,middle and high starch contents, respectively, were studied. The results showed that the effect of fertilizers on yield and starch content of potato was more than that of the varieties; the effect of bio-organic fertilizer was more than that of Mn fertilizer and Zn fertilizer; the yield of variety Zihuabai was higher than that of Bashu 10 and Neishu 3 was the last; the starch content of variety Bashu 10 was the highest and that of Neishu 3 was the lowest
