Full Crown Regeneration of aged Jujube

For the old trees with strong trunk but no natural regeneration ability, the old trees with incomplete crown main branches, rare branches per unit fruit and low yield should be renewed in the dormant period. After the main branch of the senescent plant was re-cut at one time, the adventitious buds could germinate in the spring of the same year, and the new buds in the appropriate position were selected and cultured into the extended branches of the main branches. In order to promote the rapid formation of new crowns, fertilizer and water management should be strengthened, so that backbone branches are generally formed in 2 to 3 years, and a large number of fruits are produced in 4 to 5 years, and the yield of plants is much higher than that of plants before renewal.
