| 摘 要： | 在田间条件下研究了不同氮肥用量对花生产量和固氮的影响。结果表明,在红安低氮土壤上,施氮使花生产量和氮积累量显著增加,但固氮比例快速降低;在蔡甸高氮土壤上,施氮对花生产量和氮积累量影响不明显,固氮比例变化不大。建议生产上应根据土壤条件确定施氮策略,即低氮土壤上优先考虑增加花生产量来施氮,在高氮土壤上优先考虑发挥花生固氮能力来施氮。

| Abstract: | Field experiments were arranged to study the effect of different nitrogen amount on peanut yield and biological nitrogen fixation(BNF).It indicated that in low nitrogen soil such as Hong’an,addition of N fertilizer increased the yield and nitrogen accumulation of peanut markedly,but the proportion of BNF decreased rapidly.In high nitrogen soil such as Caidian,application of nitrogen had no significant effect on the yield,nitrogen accumulation and BNF.The strategy of nitrogen application should be determined by soil fertility in production.In low fertility soil,the yield should be considered firstly when determining the use of nitrogen,while the BNF potential should be the priority consideration in high fertility soil. |
