摘　　要：通过对3种不同品种甘肃啤酒大麦叶片的生长过程的连续观测和系统分析，采用Richards方程描述了不同叶位叶片的叶长、叶宽和叶面积的动态生长过程，构建了大麦叶片生长特征的模拟模型，并用不同品种的大麦进行检验．结果表明：模型对不同品种大麦叶片叶长的RMSE值在0．76～2．74cm之间，叶宽的RMSE值在0．013～0．35cm之间，表明模型具有较好的相关性和预测可靠性．Based on the continuous observation and systematic analysis on the leaf growth process of three different barley eultivars in Gansu Province, the dynamic changes of lengths, widths and areas of leav- es at different leaf positions were described by the Richard equation,and a dynamic model was constructed to simulate the growth characteristics of barley leaves. After that, the model was validated by different bar- ley cultivars. The experimental results showed that the root mean square errors（RMSE） of leaf lengths ranged from 0. 76 to 2. 74 cm,and that of leaf widths ranges from 0. 013 to 0. 35 cm,this showed that the simulation model had good correlation and predictability.
