初中植物学教材讲某些植物的营养器官——根、茎、叶都有繁殖能力。根、茎的繁殖实例较多,但学生对叶的繁殖作用往往缺乏感性认识。为此,我们做了常见的盆栽观赏植物——八宝(景天科)叶的繁殖实验,效果较好。具体做法是:从八宝的基部取下叶片数枚,分别平放在备好的花盆内的土面上(以腐殖土为好并有一定湿度),将叶片基部稍微压入土 Junior high school botany teaching materials about the vegetative organs of some plants - roots, stems, leaves have reproductive capacity. Roots and stems breeding more examples, but the students often lack of perceptual awareness of the propagation of leaves. To this end, we do a common potted ornamental plants - Babao (Sedum) leaf propagation experiments, the effect is better. The specific approach is: remove the leaves from the base of Babao a few pieces, respectively, placed in the prepared pots of soil (Humus is better and have a certain humidity), the blade base slightly into the soil
