摘要
本研究以金山27、先玉335、伟科702、郑单958为试材,运用生理发育时间恒定的原理,构建了玉米茎鞘夹角变化的模拟模型.对模型的检验结果表明:不同品种茎鞘夹角的模拟误差在0.0-2.7°,RMSE在0.6-1.2°.模型表现出较好的预测性.
The present study based on field experiment, To Jinshan27、Xianyu335、Weike702、Zhengdan958 as the test material, By using the principle of the physiological development time constant, The research built the simulation mod-el of maize stem sheath blade Angle change. The results showed that the ranges of absolute prediction errors of the stem-sheath angle of maize were 0.0-2.7°, the root mean square errors（RMSE）were 0.6-1.2°.The model reflected an enhanced level of prediction.
