摘要
对宁夏固原地区引种的19种牧草叶片的形态及解剖学观察,并根据旱生结构特征,将19种牧草分为旱生结构一般,旱生结构比较明显和旱生结构明显3种类型。
Based on the observation of leaf blade of 19 species, these plants may be divided into three groups from the point of view of morpho-anatomy, whose characteristics of xeric structure are oharacterized in ordinary, sub-evidence and evidence respectively. So the results may provide a basis for choosing suitable fine forage grass.
