| Based on the experiment data of 2004 and 2005, and the theories of peanut physiology and ecology, following the thoughts of the RCSODS and the CERES model, a series of dynamic simulation models to describe the main processes for peanut, such as phenology, leaf age, biomass accumulation and yield formation, are developed in this study.1. Phenology model for peanutIn the research, days, effectively accumulative temperature and average temperature for the several phenology courses are educed. Compared with Big-pod varieties, the days are less in Emergence phase for Little-pod variety, the same as effectively accumulative temperature. In the phenology model q, parameters and physiological day for the varieties are gained.Parameters, k and p, for Fenghua 1 are 2.428 and 0.173 respectively in Emergence phase, 2.982 and 0.984 in Young seedling phase, 2.900 and 0.869 in Flowering and pegging phase, 3.718 and 0.613 in Pod-setting phase, 3.779 and 0.297 in Pod-maturing phase. Those for Fenghua 3 are 2.487 and 0.173 in Emergence phase, 2.987 and 0.980 in Young seedling phase, 2.907 and 0.612 in Flowering and pegging phase, 3.719 and 0.531 in Pod-setting phase, 3.780 and 0.281 in Pod-maturing phase. Those for Fenghua 2 are 2.279 and 0.167 in Emergence phase, 2.846 and 1.151 in Young seedling phase, 2.688 and 0.799 in Flowering and pegging phase, 3.561 and 0.777 in Pod-setting phase, 3.636... |
