Cut the head and force the bud to breed the back of the tortoise
Choose the larger tortoise-backed bamboo with more than 3 years old, with stem nodes and 10 layers of leaves, cut off the tender head with a leaf, and the tender head can also be cut. If in its vigorous growth period, it will soon sprout new heads in the axils of the uppermost two leaves of the stem, generally at least two new buds at a time. At this time, the aerial roots of the new buds will also grow synchronously. When the new buds grow to more than 3 leaves, the long aerial roots will naturally go into the basin soil, and then they will grow fibrous roots that can absorb nutrients. The two new seedlings are formed naturally, but they are still connected to the mother tree.
