Abstract

This invention provides a method for configuring and cultivating grapefruit pollinator trees, comprising the following steps: selecting 1-2 robust main branches of the main variety and making a smooth graft union 3-4 cm long on the main branch; selecting robust branches of the pollinator variety as scions and cutting a smooth slant 3-4 cm long at the lower end of the scion; inserting the prepared scion into the prepared graft union to form a grafted chimera; binding the grafted chimera tightly and then wrapping the scion 1-2 times tightly; after grafting, pruning all branches below the graft union; after the graft has taken and the graft union has fully healed, removing the grafting film or mulch film; after the pollinator branch has spread out, selecting one branch as an extension branch; after the pollinator branch enters flowering and fruiting, selectively removing or retaining the fruit of the pollinator variety after flowering each year. This invention can effectively achieve the purpose of configuring pollinator trees for the main variety, reducing the land area occupied by traditional pollinator tree configurations while effectively improving the marketability rate and stability of fruit quality.

Description

Technical Field

[0001] This invention relates to the field of fruit tree planting technology, and in particular to a method for configuring and cultivating grapefruit pollinator trees. Background Technology

[0002] Pomelos of the same variety or strain have weak self-pollination and fertilization capabilities, so pollinator trees must be planted to achieve high yields. Pollinator trees should be selected from pomelo varieties or strains that bloom at the same time as the main variety, have strong pollen viability, good pollination compatibility with the main variety, and have a positive impact on yield and quality. The fruits produced by pollinator trees are also pomelo varieties or strains with higher edible value.

[0003] To ensure the highest possible yield for the main cultivar, a certain proportion of pollinator cultivars should be present. Traditional pollinator tree planting methods require spacing between cultivars and pollinator trees, resulting in large pollinator tree footprints and poor pollination efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a method for configuring and cultivating grapefruit pollinator trees, which can reduce the land area occupied by traditional pollinator tree configurations while effectively improving the marketability of fruits and the stability of fruit quality.

[0005] According to one objective of the present invention, the present invention provides a method for configuring and cultivating grapefruit pollinator trees, comprising the following steps:

[0006] S1. Select 1-2 strong main branches on the main planted variety, cut them off 80cm-100cm away from the main trunk, and use a grafting knife to make a smooth 3cm-4cm long interface on the main branch.

[0007] S2. Select healthy branches of the pollinating variety as scions. The scions should be 8cm-10cm long. Cut a smooth slant 3cm-4cm long at the bottom of the scion to ensure that there are at least 3 healthy buds.

[0008] S3. Insert the scion prepared in S2 into the grafting interface opened in S1, ensuring that the cambium layer of the scion and the cambium layer of the main branch interface are closely attached to form a grafted chimera, which will become the pollinating branch in the future.

[0009] S4. Use grafting film or mulch to tightly bind the grafted chimera to prevent it from loosening, and make sure that the wound is completely covered; then wrap the scion 1-2 times tightly to prevent moisture loss, while ensuring that only 1 wrap is made at the bud point of the scion.

[0010] S5. After grafting, prune all branches below the grafting point to improve the grafting survival rate.

[0011] S6. After the grafting has taken and the graft union has completely healed, remove the grafting film or mulch film to facilitate the growth of the pollinating branch.

[0012] S7. After the pollinating branch unfolds, select one branch as the extension branch;

[0013] S8. After the pollinating branches enter the flowering and fruiting stage, the fruits of the pollinating varieties should be selectively removed or retained after the flowers wither each year.

[0014] Furthermore, in S4, when binding the grafted chimera tightly, wrap it with grafting film or mulch film from bottom to top 3-4 times.

[0015] Furthermore, in S7, timely pruning of overly vigorous branches is necessary to retain and cultivate as many flowering branches as possible. Beneficial effects

[0016] The pomelo pollinator tree configuration and cultivation method of the present invention can effectively achieve the purpose of configuring pollinator trees for the main cultivar. While reducing the land area occupied by traditional pollinator tree configuration, it can effectively improve the marketability of fruit and the stability of fruit quality. Detailed Implementation

[0020] A method for configuring and cultivating grapefruit pollinator trees includes the following steps:

[0021] S1. Select 1-2 strong main branches on the main planted variety, cut them off 80cm-100cm away from the main trunk, and use a grafting knife to make a smooth 3cm-4cm long interface on the main branch.

[0022] S2. Select healthy branches of the pollinating variety as scions. The scions should be 8cm-10cm long. Cut a smooth slant 3cm-4cm long at the bottom of the scion to ensure that there are at least 3 healthy buds.

[0023] S3. Insert the scion prepared in S2 into the grafting interface opened in S1, ensuring that the cambium layer of the scion and the cambium layer of the main branch interface are closely attached to form a grafted chimera, which will become the pollinating branch in the future.

[0024] S4. Wrap the grafting film or mulch film around the graft union 3-4 times from bottom to top to secure it tightly and prevent it from loosening, and make sure that the wound is completely covered. Then wrap the scion 1-2 times tightly to prevent moisture loss, and make sure that only one wrap is made around the bud of the scion.

[0025] S5. After grafting, prune all branches below the grafting point to improve the grafting survival rate.

[0026] S6. After the grafting has taken and the graft union has completely healed, remove the grafting film (mulch film) to facilitate the growth of the pollinating branch.

[0027] S7. After the pollinating branch unfolds, select one branch as an extension branch, prune the overgrown branches in time, and retain and cultivate as many flowering branches as possible.

[0028] S8. After the pollinating branches enter the flowering and fruiting stage, the fruits of the pollinating varieties should be selectively removed or retained after the flowers wither each year.

[0029] This invention is applicable to the pollinator tree configuration of pomelo and other "one trunk and multiple branches" (i.e., one main trunk and multiple main branches) type fruit trees. Example

[0030] Method for configuring pollinator trees for early-ripening pomelos in Dongshi:

[0031] 1. From November to March of the following year, select 1-2 strong main branches on the Dongshi early pomelo tree, cut them off 80cm-100cm away from the trunk, and use a grafting knife to make a smooth 3cm-4cm interface on the main branch.

[0032] 2. Using Thai Ruby Pomelo as the pollinating variety, take healthy branches as scions, 8cm-10cm long, and cut a smooth slant 3cm-4cm long at the bottom of the scion.

[0033] 3. Using the grafting method, the Thai Ruby scion is grafted onto the selected main branch of the Dongshi Early Pomelo to form the future pollination main branch;

[0034] 4. After pollination is completed on the main pollinating branch, remove the fruit from the main pollinating branch in a timely manner to avoid mixing the Dongshi early pomelo fruit and the Thai Ruby pomelo fruit during harvest.

[0035] Compared with the traditional pollinator tree configuration method (planting cultivars and pollinator trees at a distance), the pomelo pollinator tree configuration method of this invention can effectively achieve the purpose of configuring pollinator trees for the main cultivar. While reducing the land area occupied by pollinator trees in the traditional configuration, it can effectively improve the marketability rate of fruit and the stability of fruit quality. In addition, the pollination rate can reach more than 95% when using the pollinator tree configuration method.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
