摘  要:
为了应用CERES-Maize模型模拟吉林春玉米生长发育和产量形成,需要确定主栽春玉米品种的遗传参数。采用晚熟春玉米品种‘吉单159’和‘先玉335’多年田间观测数据和同期气象、土壤等数据进行遗传参数调试,并对模型的模拟效果进行验证。结果表明:2个春玉米品种生育期的模拟值和实测值散点均在1:1线周围。‘吉单159’播种至开花天数和播种至成熟天数RMSE值分别为3.78和10.90。‘先玉335’播种至出苗天数、播种至开花天数和播种至成熟天数RMSE值分别为1.12、3.20和4.85。2个品种春玉米的地上部生物量和叶面积指数的模拟值与实测值均在抽雄期接近,三叶期和七叶期差异最大。‘吉单159’和‘先玉335’产量的RRMSE值分别为4.31%和4.81%。说明CERES-Maize模型对吉林春玉米生育期和产量模拟效果较好,地上部生物量次之,叶面积指数一般。总之,CERES-Maize模型能够应用于吉林省气候变化对春玉米影响的评价。

摘  要:
To simulate the growth and yield of spring maize with the CERES-Maize model, main spring maizegenetic parameters of Jilin must be determined. Genetic parameters were debugged and verified based on theobserved experimental data, weather and soil data of main spring maize varieties‘Jidan159' and ‘Xianyu335'. The results showed that the measured and simulated value of the two spring maize varieties at growthstage both scattered around with 1:1 line. The RMSE value of days from planting to flowering and from plantingto maturity of‘Jidan159'was 3.78 and 10.90, respectively. The RMSE value of days from planting toemergence, from planting to flowering, and from planting to maturity of‘Xianyu335'was 1.12, 3.20 and 4.85,respectively. Simulated and measured value of top weight and LAI of the two spring maize varieties were closedat heading stage, followed by the biggest difference at three-leaf and seven-leaf stages. The RRMSE value ofyield of‘Jidan159'and‘Xianyu335'was 4.31% and 4.81%, respectively. It indicated that CERES-Maizemodel was better for simulating the growth stage and yield of spring maize in Jilin, the simulating of the aboveground biomass came the second, and the simulating of LAI was ordinary. In conclusion, CERES-Maize modelcould be applied to evaluating the effect of climate change on spring maize in Jilin Province.
