The first is to use a slightly smaller flowerpot before the spring to germinate to limit the vegetative growth of the plant and promote its sprouting in the root and neck, so as to facilitate the propagation of the branch. The second is to artificially destroy the growing point of the plant. The top bud can be used to pierce the growing point with a thicker veterinary needle after cutting off the flame, or cutting off the top bud with a knife. These two measures can effectively promote the emergence of axillary buds at its base. Pay attention to artificially stab wounds or cut off wounds at the growing point. Don't contaminate the waste water to prevent the wounds from rot, resulting in the failure of axillary buds or partial necrosis of the plants. When two to three leaves of the young shoots to be spawned are grown, the mother plants are removed from the flowerpots in combination with a change of pots, the ion strains are cut with a knife, and pot plants are selected separately. For some species with many stem segments, three to four leaf numbers can be used as a cutting unit because air roots can occur at each node. To promote the emergence of lateral buds in the lower leaf axils, several days before cutting the stem sections, Cutting a depth of 0.5 cm can cause buds to sprout early in the leaf blade above the wounded part;
