Embodiment Construction

[0014] Below in conjunction with describe the present invention in detail

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

[0016]

[0017]

[0018] As shown in Table 1 above, with the increase of jujube branch age, the number of jujube branches, the length of jujube hanging, the number of fruits and the yield after 5 years of age are decreasing year by year.

[0019]This application utilizes the characteristics of jujube latent buds with long lifespan and strong germination ability. When the jujube tree enters the fruiting period, the backbone branches and fruiting branch groups are purposefully cultivated and renewed, and the fruiting branch groups of the whole tree are always maintained. In the robust fruiting stage, a high-yield, stable, high-quality, and efficient cultivation mode is realized.

[0020] For jujube trees that have entered the aging and fruiting period, the main branches, side branches, and fruitin...

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...
