| 摘 要： | 研究了不同水分与氮肥形态配比对苋菜养分和产量的的影响,结果表明:同一水分条件下,苋菜的N,P,Fe含量随NH4 -N比例的增大而增加;K,Ca含量随NH4 -N比例的增大而减小。苋菜的产量随NO3--N比例的增大而增加。同一施肥条件下,苋菜N,P,Fe含量随水分的增加而增加;苋菜的K,Ca含量、产量以中水处理最高。

| Abstract: | Pot experiment was conducted to study the effects of different NO-3-N/NH 4-N ratios on nutrient and yield of amaranth in different condition of water.The results showed that the N,P,Fe contents of amaranth increased and the K and Ca decreased with the increasing of NH 4-N/NO-3-N ratio in the same irrigation amount.The yield of amaranth increased with the increasing of NO-3-N/NH 4-N ratio in the same irrigation amount.The N,P,Fe contents of amaranth increased with the increasing of irrigation amount;the K,Ca contents and yield of amaranth were highest in middle irrigation amount. |
