生物有机肥在马铃薯上的施用效应

选用3种类型马铃薯品种青薯5号、渭薯8号、青薯2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青薯2号＞青薯5号＞渭薯8号,对淀粉含量的效应为青薯2号＞青薯5号＞渭薯8号.

Effects of Bio-organic Fertilizer on Potato

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,mid-dle 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 Qingshu 5 was higher than that of Qingshu 2 andWeishu 8 was the last;the starch content of variety Qingshu 2 was the highest and that of Weishu 8 was the lowest.
