摘要
利用玉米生长观测资料、气象资料、土壤资料、田间管理资料,采用CERES-Maize模型对玉米进行应用研究。首先运用均匀设计进行数值模拟,并对模拟结果进行回归分析,根据模拟及优化结果选取最佳的遗传参数,最后通过模型对玉米的产量、每平方米粒数、生育期模拟值和观测值间的比较,结果表明总体上模型模拟值和观测值之间具有很好的一致性。
Based on maize growth data,weather data,soil information and field management information,using CERES-Maize model,uniform design was used to conduct numerical simulation and the method of regression analysis was used to analyze simulation results.According to the simulation or optimization results,the best genetic parameters were selected.Through comparing simulated value of the production of corn and grains per square meter during growth period with measured value of those,the results demonstrated that the simulated value of the model and observed value fit each other very well in general.
