英文摘要	SMCR_N is a recently developed sophisticated model which simulates crop response to nitrogen fertilizer for a wide range of crops, and the associated leaching of nitrate from arable soils. The objective of this study was to investigate the possibility of using SMCR_N model as a research tool to investigate interactions between the amount and timing of N application and effects on vegetable production and environmental impact. In this paper, we used data from 16 field plot experiments to carry out the model calibration and found out that the simulated values of crop dry weight were strongly correlated with the measured values throughout growth in all the experiments with a R-2 of 0.9248. Then we choose the field plot 1 to carry out the model validation. The simulated soil mineral N concentration was less satisfactory, although statistically the simulated values of soil mineral N concentration were still correlated fairly well with the measured values (R-2 = 0.766). This indicate that the model has the potential to optimize N use and assess the impact of N leaching in eggplant production under the temperate continental monsoon climate of the North China Plain.
