The upper part of the leaves is left in the sorghum, and the lower half of the leaves are cut. The general type can be rooted without any treatment. After soaking the lower part of the cuttings with a small amount of sucrose water for 8 to 12 hours, the cutting cutting can promote rooting, and the low concentration of indole butyric acid (10~20 μg/g) soaks the cuttings. The species that are not easy to root have a promoting effect.

5, ramets breeding
The clumped rhododendron old strain can be obtained by the ramets method, but after the ramets, there are more roots, which often affect the growth, and the wounds are perishable, and the survival rate is not so ideal. Therefore, the ramets propagation method is rarely used.
