摘要
通过田间试验来检验水稻模拟模型（ＲＳＭ）对不同地区、不同施肥处理、不同生育期遮光４５％处理的适应性．检验结果表明：不论何种处理，ＲＳＭ的模拟值与观察值在光合产物积累、稻株养分含量等方面的吻合程度较高，回归方程的Ｆ值检验大都达到极显著水平，回归载距和回归系数的ｔ测验值大都不显著．这表明ＲＳＭ的模拟变化趋势及大小与田间取样一致．ＲＳＭ也能较满意地重现最后的产量及穗粒构成．
Field experiments in different areas,at different seasons,under different fertilization schemes and under shading condition at different growth stages were conducted tovalidate the adaptability of Rice Simulation Model (RSM) The results show that the simulated values of RSM fit well with the measured values in dry matter accumulation, nutrient content,yield and its components regardless of the treatments The F values of the regression equations are highly significant The general trends of the simulated values fit well with the measured values The t values of both the regression intercept and coefficients are not significant,which indicate the simulated values fits well the measurements Yield components of the RSM fits well with the field data
