| Abstract | The water balance in plot- to- plot irrigation for paddy fields was investigated for irrigation management. A field experiment was carried out in order to simulate the two chosen irrigation methods: intermittent irrigation and instantaneous irrigation. A simulation model was developed with reference to the irrigation interval, the maximum allowable ponding depth, the plot size of paddy fields and the relationship between the experiment and the simulation model. The simulation model was realized by two programmes run in FORTRAN 77 based on the climatological data of raining season in the past 30 years. Through analysis of the simulation results, the effects of irrigation interval, plot size and maximum allowable ponding depth on effective rainfall and water deficit were discussed in regard to the plot-to- plot irrigation of paddy fields. The effective rainfall and water deficit in paddy fields are two criteria of evaluating the simulation results. Comparison of the two irrigation methods shows that the advantages of irrigation method depend on the physical components of paddy fields in plot-to-plot system. |
