不同肥料配施对冀张薯8号养分吸收和产量的影响

摘要

This study uses the method of field trials and lab tests to discusses the consistent in the NPK fertilizer application conditions, different biological fertilizer and NPK fertilizer application of Jizhang 8 potato different growth and quality of crops, increase organic fertilizer (T2), soil physical and chemical properties have obvious changes, as well as the economic characters and yield of Ji zhang potato 8 also has the change, the change rule between the three processing T2 > T3 > T1, namely the NPK + Biological organic fertilizer > NPK + Fulvic acid potassium > NPK, but reached the maximum at T3 soil available nutrients, three processing the change rule between the T3 > T2 > T1, namely the NPK + Fulvic acid potassium > NPK + Biological organic fertilizer > NPK, the experimental results show that the combination of organic manure and chemical fertilizer reasonably and effectively on soil fertilizer and potato yield and improving quality has important significance.%采用田间试验和室内测试分析相结合的方法，探讨在氮磷钾肥施用一致的条件下，不同生物肥料与氮磷钾肥配合施用对冀张薯8号养分吸收和产量、品质的影响.结果表明：增施有机肥，土壤理化性质有明显变化，同时冀张薯8号的经济性状和产量也有变化，不同处理的影响程度大小依次为NPK+生物有机肥、NPK+黄腐酸钾、NPK.增施黄腐酸钾对提升土壤速效养分效果显著，不同处理的影响程度大小依次为NPK+黄腐酸钾、NPK+生物有机肥、NPK.有机肥与化肥合理有效地结合起来，对土壤培肥和马铃薯产量及品质的提升有重要作用.
