摘　　要：以水稻品种“辐优17”为试材,于2018年3月—2020年9月在合肥市农业气象试验站开展大田分期播种试验,试验设置4个播期。将由实测气象数据进行计算得到的光温效应(ATIE)、辐热积(TEP)和积温(GDD)与测定的干物质分配比例参数进行拟合,建立大田水稻干物质分配动态模拟模型,并比较各模型拟合效果。结果表明:ATIE模型模拟效果较好,R2均>0.90,与传统的辐热积法和积温法相比,ATIE显著提高了水稻干物质分配预测精度,可为大田种植作物营养生长和生殖生长指标模拟提供参考。The rice variety“Fuyou 17”was used as the test material,a field phased sowing experiment was conducted at the Hefei Agricultural Meteorological Experimental Station from March 2018 to September 2020,with four sowing dates set for the experiment.Fit the light temperature effect(ATIE),radiant heat product(TEP),and accumulated temperature(GDD)calculated from measured meteorological data with the measured dry matter distribution ratio parameters,establish a dynamic simulation model for dry matter distribution in rice fields,and compare the fitting effects of each model.The results showed that the simulation effect of the ATIE model was good,with R2 greater than 0.90.Compared with the traditional radiation heat accumulation method and accumulated temperature method,the ATIE model significantly improved the prediction accuracy of dry matter distribution in rice,and can provide reference for the simulation of crop nutritional growth and reproductive growth indicators in the field.
