Abstract
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.关键词
