通过氮肥减量和替代确保水稻稳产,提高氮肥利用效率,实现资源节约和环境友好的双重目的。试验设计不施氮（N0）、3种减氮配施生物有机肥和3种减氮配施钮翠绿有机复合液肥施肥模式,以当地施肥水平为对照,研究生物有机肥或钮翠绿有机复合液肥配施及不同减氮比例处理对水稻产量和氮肥利用效率的影响。结果表明:生物有机肥配施模式平均减氮30%的情况下,早、晚稻的平均产量略低于常规施肥模式,钮翠绿有机复合液肥配施模式表现出类似的趋势;与常规施肥模式相比,生物有机肥或钮翠绿有机复合液肥配施平均减氮30%的情况下,氮肥偏生产力平均提高了34. 3%,表明通过施用生物有机肥或钮翠绿有机复合液肥配施减...

By nitrogen reducing and replacement,the rice grain yield can be maintained and nitrogen use efficiency can be improved,which achieve dual purpose of resource saving and environment friendly.Designing six fertilization modes including nitrogen-free(N0),three nitrogen-reducing combined application of bio-organic fertilizer and three nitrogen-reducing combined application of organic compound liquid fertilizer Niucuilü,using the local fertilization level as the control,this paper study the effects of application of bio-organic fertilizer or Niucu...
