摘要：

以优质丰产杂交中籼稻徽两优898和Y两优900为试验材料开展田间小区试验，钵苗机插条件下设置5个施氮量处理 (0、75、150、225、300 kg ha^-1)，利用不同生育时期水稻地上部干物质量累积和植株氮浓度构建钵苗机插杂交籼稻临界氮浓度稀释曲线，利用该曲线计算NNI和N_and诊断氮素营养状况，进而探究NNI 与N_and和相对产量（RY）的关系。施氮处理显著增加钵苗机插杂交籼稻地上部生物量和植株氮浓度（P<0.05），钵苗机插杂交籼稻临界氮浓度（N_c）与地上部生物量（DM）之间符合幂函数曲线N_c=4.02DM^-0.42（R²=0.97），模型RMSE 和n-RMSE 分别为0.23、10.61%，表明模型具有较好的准确性和稳定性。整个生育期内植株NNI 值范围为0.58~1.31，与之对应的N_and值为-55~109 kg ha^-1。各生育时期NNI与N_and的存在显著线性模型关系（0.53<R²<0.99，P<0.01），而NNI与RY间满足线性平台模型关系（0.73<R²<0.92，P<0.01）。本研究构建模型可用于诊断钵苗机插杂交籼稻氮素营养状况，为定量氮肥管理提供依据。

Abstract:

Field experiments of nitrogen (N) treatment at five different application rates (0, 75, 150, 225, and 300 kg ha⁻¹) were conducted under pot-seedling mechanical transplanting (PMT) in 2018 and 2019. Two high-quality and high-yielding hybrids of indica rice, Huiliangyou 898 and Y Liangyou 900, were used in this study. The N nutrition index (NNI) and accumulated N deficit (N_and), used to assess the N nutrition status in real-time, were calculated for the indica cultivars under PMT with a critical nitrogen concentration (Nc) dilution model based on shoot dry matter (DM) during the whole rice growth stage. The relationships between NNI and N_andwith relative yield (RY) were determined, and accurate N application schemes were developed for hybrids indica rice under PMT. The results indicated that high application rate of N-fertilizer significantly increased the concentrations of shoot DM and N in aboveground organs during the observed stages in the two cultivars for two years (P<0.05). The Nc dilution model of hybrid indica cultivars was N_c=4.02DM^−0.42 (R²=0.97) combining the two cultivars under PMT. Root-mean-square error and normalized root-mean-square error of the curve verification were 0.23 and 10.61%, respectively. The NNI and N_andranged from 0.58 to 1.31 and 109 to –55 kg ha⁻¹, respectively, in the two cultivars for all N treatments. NNI showed a linear relationship with N_andduring the entire growth stage (0.53<R²<0.99, P<0.01). In addition, NNI showed a linear-plateau relationship with RY (0.73<R²<0.92, P<0.01) throughout the observed stages. These results suggest that the models can accurately diagnose the N-nutrition status and support effective N-fertilizer management in real-time for hybrid indica rice under PMT.
