| Abstract: | By comparing two models simulated relation between nitrogen fertilizer rate and corn yield under transplanted pattern, the results show that the linear plus plateau model can simulate the relation well. The optimal nitrogen fertilizer rate for transplanted corn and the optimal corn yield then can be obtained from the model. Thereafter, the critical values of corn leaf nitrate concentration and nitrate concentration in 0~30cm-soil layer are determined for nitrogen fertilizer dressing. |
| Keywords: | Fertilization model transplanted corn nitrogen diagnosis |
