Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with

[0015] Table 1 shows the growth results of jujube strands of different branch ages of Jinsixiaozao

[0016]

[0017] As shown in Table 1 above, with the growth of jujube branch age, the number of jujube stocks and the length of jujube hanging after 5 years of birth, the number and output of jujube are decreasing year by year.

[0018] This application takes advantage of the long lifespan of the latent buds of the jujube tree and the strong budding power of the hidden buds. When the jujube tree enters the fruiting period, its backbone branches and fruiting branch groups are purposefully cultivated and renewed, and the fruiting branch groups of the whole tree are always maintained At the stage of robust results, the cultivation mode of high yield, stable yield, high quality and high efficiency is realized.

[0019] For jujube trees that have entered the senescence and fruiting stage, follow the results ...

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 particularly relates to a method for rejuvenating and rejuvenating the jujube in the senescence period after the jujube has entered the fruiting period for many years. Background technique [0002] Jujube is one of the special fruit trees in China. It has a long history of cultivation, a wide distribution area, rich nutrition, wide use, strong adaptability, early results, long life span, and is known as the "iron crop". Most jujube trees are in the period of fruiting and senescence for many years. As the age of the trees increases year by year, the age of the branches also increases year by year, which leads to the aging of the fruiting branch group, and the fruiting ability continues to decline. After years of fruiting, the main branch, lateral branch and fruiting The front part of the branch group often droops year by year due to years of heavy fruit pressure. In severe cases, the bran...
