| 摘 要： | 通过系统分析甘肃地区不同株型大麦品种茎秆生长的变化动态,以生理发育时间(PDT)为步长,用Richards方程模拟了甘肃大麦茎秆节间伸长和节间增粗的动态过程,并以不同品种不同播期的大麦对模型进行了检验。结果表明:模型对大麦不同品种不同播期节间长度实测值和模拟值的RMSE范围在0.37~1.62 cm之间,节间粗度的RMSE范围在0.011~0.034 cm之间,模型具有较好的预测性。

| Abstract: | Based on the analysis of different barley varieties in Gansu,using the Richard equation,this article presents a dynamic simulation of internode elongation and thickening process at physiological development time(PDT).The dynamic models were validated in various sowing dates and different genotypes of barley in Gansu.Experimental results showed that the ranges of the root mean square errors(RMSE) of internode length in various sowing dates and different genotypes of barley were 0.37～1.62 cm,and that of internode thickness were 0.011～0.034 cm.The two simulating models showed separately good correlation and predictability. |
