摘要
本文运用具有时迟效应的Logistic修正模型,对上海市早稻、单季稻、后季稻群体密度增长过程进行了动态模拟。结果表明修正模型比原模型更接近实际情况。
On the basis of analysis of the regularity of rice colony density variation, defects of the logistic model in the simulation of the grow.h process of paddy rice colony density are indicated. Therefore a modified logistic model with time-lag effect is used in the dynamical simulation and its biological significance is discussed. Simulation results for the density variation of the early rice, Single-crop rice, late rice show that the revised model is much better.
