The fruit-bearing age of pomegranate trees varies with different propagation methods and varieties. It takes 3 ~ 1 years for the real pomegranate to blossom and bear fruit, while the pomegranate with double petals or agate, which is mainly for flower viewing, can blossom in the same year of sowing. The continuous fruiting period of pomegranate trees can be as long as 5 ~ 6 years, and then the yield will gradually decrease and enter the aging period. After entering the aging period, the fruiting period can still be maintained for 2 ~ 3 years. Therefore, the life of pomegranate trees can be as long as a hundred years, and if cultivated and managed properly, it can reach more than 2 years, but the economic cultivation period is only 7 ~ 8 years.

The branches of pomegranate trees are generally thin and thin, with obvious axillary buds, and the tips of the branches are needle-like and opposite; The apex of a long branch, sometimes whorled. In one year, the growth of the particularly vigorous branches can be continuously extended from Zhixia in spring to autumn, and the length can reach 1 ~ 2 meters; Among them, secondary branches and tertiary branches can be sprouted from the upper part. These secondary branches and tertiary branches are almost at right angles to the parent branches and extend horizontally. Therefore, the growth is generally not strong. These secondary branches and tertiary branches, especially the secondary branches, can form mixed buds in the same year and blossom and bear fruit in the second year.

Anyone who has obvious leaf buds, whether it is a twig 4-5 cm long or a twig over 1 meter long, generally has no terminal buds; However, the growth is extremely weak, with several leaves clustered at the base, and there are terminal buds without obvious axillary buds. The terminal buds of these extremely short branches can develop into mixed buds in the same year, and blossom and bear fruit in the second year. If they are malnourished, the terminal buds will still be leaf buds, and they will grow weakly in the second year, and they will still be extremely short branches. However, if they are stimulated, they may sprout long branches.

The fruiting habit of pomegranate trees is to produce fruiting branches on the fruiting mother branches. Results Most of the mother branches were primary branches growing in spring or secondary branches sprouting in early spring. Because these branches were formed earlier, their growth and development were more substantial. In the second year, new shoots of about 6 ~ 2 cm were grown from the terminal buds or axillary buds of these branches, and generally 1 ~ 5 flowers could be planted on these new shoots. This new shoot, which bears flowers and fruits, is called fruiting branch. Among the flowers borne on the fruiting branches, one is terminal, the others are axillary, and the terminal bearing fruit is better. Those who bear two fruits at the same time are called "parallel pomegranate"; When five flowers can bear fruit, they are called "five sons are admitted to the family".

The fruiting branch of pomegranate tree can't continue to grow forward because its apex has borne fruit, so its nutrition is concentrated and its development is robust. In the second year after bearing fruit, its lower branch can still form fruiting mother branch or growing branch.

Pomegranate trees have a large number of flowers, but the flower and fruit drop are serious and the fruit setting rate is very low, so the yield is unstable and the phenomenon of big and small years is serious. According to the investigation in Fengcheng, Zaozhuang City, Shandong Province, pomegranate trees generally enter the full fruit stage when they are about 15 years old, with a plant yield of 2-3 kg, and the highest plant yield can reach 5-1 kg.
