    摘要:

    以常规粳稻徐稻3号为供试材料,设置不同养分管理试验,研究了养分管理措施对水稻产量、叶面积指数、齐穗期株型以及氮素利用效率的影响。结果表明,通过养分优化管理,能有效提高江苏常规粳稻产量和氮素利用率。与当地高产模式相比,高产高效模式(合理投入获得高产)增收效益最为明显,较其增收4 366.5元/hm2,氮素利用率从17.7% 提高到了36.1%。

    Abstract:

    The effects of nutrient management, leaf area index(LAI), the shape of heading stage and the nitrogen use efficiency were studied under different nutrient treatments (4+X) by taking Xudao3 as the material. The results showed that optimizing nutrient management could increase the yield and the nitrogen use efficiency. Compared with the local high-yield mode, the high-yielding and high-N-use-efficiency cultivation mode increased the economic income by 32.7% (4 366.5 Yuan/hm2) and increased the nitrogen use efficiency from 17.0% to 36.1%.
