Rejuvenation and fruit bearing method for aging fruit bearing jujube trees

Abstract

The invention especially relates to a method for rejuvenating aging fruit bearing jujube trees without influencing normal fruit bearing. The method comprises following steps: (1) when jujube trees enter aging fruit bearing stage, purposive new branch cultivation is performed on main branches and fruit bearing groups; (2) renewing is performed as well as fruit bearing on the main branches, side branches and fruit bearing branch group of jujube trees which have already entered aging fruit bearing stage and whose output per plant is under 7.5 kg; (3) new main branches are renewed and cultivated for 3 to 5 years; (4) band girdling is performed after the jujube trees enter full flowering stage; (5) pinching is performed on newly cultivated newborn jujube heads according to the growth condition from early July to early August for enhancing the thickening and lengthening growth of second shoots on the jujube heads; (6) base part branch drawing is performed on newborn jujube heads according to growth part and growth space in the middle and late August. The method of the invention solves the problem that girdling tree protecting without output adopting renewing such as light renewing, middle renewing or heavy renewing so that the purpose of continuous high yield is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for rejuvenating and fruiting jujube trees in the senile stage when jujube trees have entered the fruiting period for many years. Background technique [0002] Jujube tree is one of the specialty fruit trees in my country. It has a long history of cultivation, a wide distribution area, rich fruit nutrition, wide use, strong adaptability, early results and long life. It is known as "hardcore crop". Most jujube trees are in the aging period of many years of fruiting. As the age of the trees increases year by year, the age of branches is also increasing year by year, resulting in the aging of the fruiting branch groups and the continuous decline in the fruiting ability. After many years of fruiting, the main branches, side branches, fruiting The front of the branch group often sags year by year due to the heavy pressure of the fruit for many years. In se...

Problems solved by technology

These three kinds of renewal methods all have the jujube regeneration period yield to reduce or have no yield, in order to solve this difficult problem, must explore and be applicable to while rejuvenating and rejuvenating the jujube tree, do not affect the normal result and jujube fruit quality. new technology
