Before germination, cut off the big sprouting tillers in the rhizosphere of the mother tree from the base to promote rooting, and then cultivate the soil for 8 cm to 10 cm to keep the soil moisture. After autumn, the rooted plants are cut off from the mother plant and become seedlings. In spring, the sprouting stick can also be bent and pressed into the soil to 10 cm to 20 cm, several places can be scratched with a knife to promote new roots, and the top end can be exposed to make it stand upright, then the contact with the mother plant can be cut off, and seedlings can be dug and planted by roots. Or in the pomegranate growing season, the branches close to the ground are bent downward, one of them is buried in the soil, the buried part is cut with a knife to promote rooting, and after rooting, it is cut off from the mother plant to form new pomegranate seedlings. It is best to bury in the soil of 15 cm when layering. Too deep and low temperature is not conducive to rooting, and too shallow and easy to air dry is not conducive to rooting.
For rare species, the method of layering in the air can be used to breed. Some branches can be cut off with a knife, and then covered with pots or other containers that can be divided into two halves, filled with substances that are easy to store water, such as marl soil or moss, and bound with plastic sheets after pouring enough water to keep them moist at ordinary times. After rooting, it can be planted by cutting from under the container.
