To monitor the fate of15N-labeled fertilizer，three microplots（0.4 m×0.5 m×0.5 m；2016–2017）without top and bottom were established within the fertilized plots，with the length perpendicular to the rows at 3–5 cm higher than ground level.15N–labeled urea（46.6%N，20.14 atom%，provided by the Shanghai Chem-Industry Institute）was applied to the microplots in the same doses as applied to the corresponding field trials.The application rates of all other fertilizers（P2O5and K2O）and the application times were the same as those in the field.The number of seeds was calculated according to design in the field and seeds were sown artificially in two rows parallel to the rows in the field.Detailed stages and fractions of15N-labeled fertilizer application are shown in Table 2.
