Abstract: In order to investigate the effect of plug and media on the growth of kalanchoe cutting in a solar greenhouse，different plug size and media type were treated to the young and old stems of kalanchoe cutting . The results showed that plug size and media type have significant influence on the plant height, stem diameter, root number, fresh weight and dry weight of the root, stem and foliage. And there is also an interactive effect between the plug size and media type. The ratios of dry weight to fresh weight of the root and stem are enhanced greatly by the flat plug. The plant height treated by the substrate of peat and vermiculite is the highest of all the treatments, and so is the stem diameter by the soil.
