Compared with fertilizing NO - 3 alone,EAN significantly increased N concentration and accumulation in leaves,sheaths,and whole plant,but there were not significant effects on roots. EAN had no significant effects on concentration of P and K,but decreased that of Ca and Mg in whole plant. EAN increased accumulation of P,K,and Ca in whole plant,and decreased that of Mg,whereas single NH\++\-4 decreased accumulation of all mineral nutrients. EAN had different effects on accumulation of mineral nutrients in different genotypes. Compared with fertilizing NO\+-\-3 alone,EAN increased accumulation of P,K,and Ca of YM158 and LZ953. For the accumulation of JDM,there was little responsive to EAN. These results indicated that EAN promoted N absorption and increased accumulation of N,P,K,and Ca in whole plant.展开更多
