Problems solved by technology

Carry out bark grafting on the main trunk of the jujube tree, because the trunk of the jujube tree has grown and developed for many years, and the cortex is thicker, so it is difficult to use the method of bark grafting; secondly, after the grafting survives, the healing between the scion and the trunk It is more difficult, the growth and development of the surviving scion is relatively slow, and at the same time, due to the insufficient connection strength between the rootstock and the scion after healing, the grafted surviving scion is easy to break from the base under the condition of wind blowing, resulting in graft failure
Therefore, there are the problems of difficult operation, low survival rate, weak growth and development after survival, and low preservation rate in the existing jujube grafting method.

Embodiment 1

[0023] This embodiment provides a kind of method of jujube grafting wild jujube, it comprises the following steps:

[0024] S1, in October before grafting, cut off the trunk of the jujube tree to be grafted during the dormancy period, so as to stimulate the jujube tree to germinate several new jujube heads.

[0025] S2. After the new jujube heads germinate, the new jujube heads with unsuitable growth positions are wiped with buds, and 4 new jujube heads with suitable positions are reserved for cultivation, so as to prepare the number and growth positions of the new jujube heads as the grafted jujube roots branch.

[0026] S3, during the growth and development of the reserved new jujubes, carry out topping treatment to ensure that the reserved new jujubes can grow robustly; then, after the new jujubes have grown and fallen leaves dormant through a growth period, they will be carried out when they germinate in the second year. Grafting jujube can be grafted by split grafting. C...

Embodiment 2

[0028] This embodiment provides a kind of method of jujube grafting wild jujube, it comprises the following steps:

[0029] S1, 14 months before grafting, cut off the main trunk of the jujube tree to be grafted during the dormancy period, so as to stimulate the jujube tree to germinate several new jujube heads.

[0030] S2. After the new jujube heads germinate, the new jujube heads with unsuitable growth positions are degerminated, and 6 new jujube heads with suitable positions are retained for cultivation, so as to prepare the number and growth positions of the new jujube heads as the grafted jujube roots branch.

[0031] S3, during the growth and development of the reserved new jujubes, carry out the tip cutting process to ensure that the retained new jujubes can grow vigorously; then, after the new jujubes go through a growing period of growth and development, after the deciduous dormancy, when they germinate in the second year To graft jujube jujube, specifically, the met...

Embodiment 3

[0033] This embodiment provides a kind of method of jujube grafting wild jujube, it comprises the following steps:

[0034] S1, 12 months before grafting, cut off the main trunk of the jujube tree to be grafted during the dormancy period, so as to stimulate the jujube tree to germinate several new jujube heads.

[0035] S2. After the new jujube heads germinate, the new jujube heads with unsuitable growth positions are wiped and degerminated, and 5 new jujube heads with suitable positions are reserved for cultivation, so as to determine the number and growth positions of the new jujube heads, as Branches of grafted wild jujube.

[0036] S3, during the growth and development of the reserved new jujube heads, carry out topping and cutting tips to ensure that the reserved new jujube heads can grow robustly; Graft jujube jujube when it is sprouting. Specifically, it can be grafted by split grafting. Choose the scion of jujube jujube with the same thickness as the new jujube head, ...

Abstract

The invention is suitable for the technical field of wild jujube production, and provides a method for grafting jujubes with wild jujubes. The method comprises the following steps that before grafting, trunk cutting is performed on a jujube tree to be grafted with the wild jujubes so as to stimulate the jujube tree to germinate a plurality of new jujube heads; after the new jujube heads germinate, the new jujube heads with inappropriate growth positions are treated, and the new jujube heads with appropriate positions are reserved for cultivation and serve as branches for wild jujube grafting; pruning is carried out in the growth and development period of the reserved new jujube heads, and wild jujube grafting is carried out in the germination period of the new jujube heads in the next year. According to the method for grafting the jujubes with the wild jujubes, the grafting difficulty can be reduced, the grafting survival rate and the preservation rate are increased, and a good grafting effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of wild jujube production, and in particular relates to a method for grafting jujube wild jujube. Background technique [0002] Using jujube tree to graft jujube is a method commonly used in the field of jujube cultivation technology, but using jujube tree to graft jujube is the latest a kind of jujube cultivation technology. [0003] However, the jujube tree grafting jujube technology commonly used now is to use the method of inserting the skin to graft on the trunk of the jujube tree, which has great difficulty in grafting, low survival rate of grafting, poor growth and development after grafting survives, and is easy to suffer from wind breaks, etc. shortcoming. Specifically, in recent years there has been a technique of grafting jujube on jujube trees. Generally, the jujube jujube scion is directly grafted on the trunk of the jujube tree by inserting the skin, and then the trunk of the jujube tree is gr...
