| 摘 要： | 研究了不同肥料组合对马铃薯产量、品质和土壤大量元素有效养分含量的影响。结果表明,与常规施肥相比,各处理仅以在配方肥的基础上增施有机肥和土壤调理剂分别提高马铃薯产量17.7%和12.9%。施用配方肥和在配方肥基础上增施土壤调理剂、中微肥提高了马铃薯VC含量,分别为9.2%,9.6%,9.2%。各配方肥处理均提高马铃薯淀粉、粗蛋白和磷含量,增幅分别为10.5%～13.0%,21.5%～40.8%和3.5%～27.2%。施用配方肥和在配方肥基础上增施土壤调理剂分别降低了马铃薯还原糖含量14.1%和5.6%,施用配方肥的基础上增施有机肥和土壤调理剂增加了马铃薯块茎的钾含量7.0%和10.9%。施用中微量元素肥料、有机肥料、土壤调理剂可提高马铃薯土壤有机质和大量元素有效养分含量,改善土壤肥力水平。

| Abstract: | The effects of different fertilizer combinations on yield and quality and content of available macronutrient in the soil of potato was carried out.The results indicated that compared to the conventional fertilization,soil conditioner and organic manure based on formula fertilization could raise the yield of potato17.7% and 12.9% respectively.The content of vitamin C in potato was raised to 9.2%,9.6% and 9.2% respectively in the formula fertilizer,soil conditioner and secondary and microelement fertilizer treatments based on formula fertilizer as compared with the conventional fertilization.The contents of starch,crude protein and phosphorus were increased by 10.5%-13.0%,21.5%-40.8% and 3.5%-27.2% respectively in all formula fertilizer treatments.The soluble sugar of potatoes was reduced 14.1% and 5.6% by formula fertilization and soil conditioner based on formula fertilization respectively.The content of potassium in potato was enhanced by 7.0% and 10.9% respectively in the organic manure and soil conditioner treatments based on formula fertilization.Application of secondary and microelements fertilizers,organic fertilizers and soil conditioner could increase the content of organic matter and available macronutrient in the soil,and improve soil fertility. |
