摘　　要：采用田间试验和室内分析方法,以新型高效含钾中微量元素肥料——碳酶钾、普通氯化钾和硫酸钾为供试肥料,研究不同类型钾肥对马铃薯生物量、块茎养分与品质、产量及土壤肥力的影响。结果表明:施用碳酶钾较普通肥料显著提高马铃薯的生物量、块茎养分含量、产量及品质,并显著提高土壤养分含量和肥力水平。Using the methods of field experiment and laboratory analysis , the effects of different types of potash fertilizer on potato biomass , tuber nutrients and quality , yield and soil fertility were studied taking Car-bon Enzyme Potassium , ordinary potassium chloride fertilizer and potassium sulphate as tested fertilizers .Car-bon Enzyme Potassium is a new type high -efficiency potash fertilizer with medium trace elements .The results showed that the application of Carbon Enzyme Potassium significantly increased potato biomass , tuber nutri-ents, yield and quality;the soil fertility was also increased significantly .
