摘　　要：为探寻氮素形态对马铃薯生长和块茎品质的影响,进行了田间试验。以‘宣薯2号’为试验材料,设置了100%硝态氮肥、100%铵态氮肥、100%酰胺态氮肥、50%硝态氮肥+50%铵态氮肥、50%铵态氮肥+50%酰胺态氮肥、50%硝态氮肥+50%酰胺态氮肥6个处理,比较不同处理马铃薯生长、产量及块茎品质特性。结果表明:氮肥混合使用比单一施用能提高马铃薯产量及品质,酰胺态氮与铵态氮或者酰胺态氮与硝态氮混合时马铃薯产量较高,而酰胺态氮与铵态氮混合时马铃薯品质更佳。综合考虑多个因素,认为50%铵态氮+50%酰胺态氮更适宜马铃薯栽培。To explore the effects of nitrogen forms on potato growth and tuber quality,a field experiments was conducted.Using'Xuanshu 2'as the experimental material,six treatments were set up:100%nitrate nitrogen fertilizer;100%ammonium nitrogen fertilizer;100%amide nitrogen fertilizer;50%nitrate nitrogen fertilizer+50%ammonium nitrogen fertilizer;50%ammonium nitrogen fertilizer+50%amide nitrogen fertilizer;50%nitrate nitrogen fertilizer+50%amide nitrogen fertilizer;and 50%nitrate nitrogen fertilizer+50%amide nitrogen fertilizer.The study compared the growth,yield and tuber quality characteristics of potatos under different treatments.The results showed that the yield and quality of mixed nitrogen fertilizer were higher than that of single application of potato,and the yield of potato was higher when amid nitrogen was mixed with ammonium nitrogen or with nitrate nitrogen.However,the quality of potatos was better when amid nitrogen was mixed with ammonium nitrogen.Considering multiple factors,it's concluded that 50%ammonium nitrogen+50%amide nitrogen is more suitable for potato cultivation.
