Abstract

A method for grafting multiple rootstocks of fruit trees is to plant more than two rootstocks in pots, and form more than two grafting ends on the tops of more than two rootstocks for grafting side branches of a fruit tree to form a mother tree, and plant it in another pot For two or more leaning rootstocks, cut at the top of the two or more leaning rootstocks to form an abutting end. Use the side branch of the mother tree as the second scion, and cut around the middle section of the second scion to form more than two abutment To complete the abutment preparation by fixing two or more abutting ends close to two or more abutting portions; by the above method, after the two or more abutting rootstocks have healed with the second scion, cut off The lower part of the second scion completes another mother tree. Because the second scion still receives nutrients from the original mother tree when docking, and the mother tree has the roots of two or more rootstocks, the mother tree is strong and not easy to be damaged when docked, and grows fast. The success rate of cultivating other mother trees is high.

Description

Docking method of multiple rootstocks of fruit trees

The invention relates to a method for docking plant branches, in particular to a method for docking multiple rootstocks of fruit trees.

Since the fruit trees grown from the fruit have different genes, they have different characteristics in physique and fruit quality. Some fruit trees have good physique and produce more fruits with good quality, and some may not have such excellent gene performance. .

In the past, in order to cultivate fruit trees with strong physique and high juicy and sweetness, the side branches of the fruit tree were used as the grafting of the scion and the single rootstock to replicate fruit trees with the same excellent genes. However, because the scion and the rootstock are one-to-one Grafting relationship, therefore, the roots of a single rootstock are not efficient enough to transport water and nutrients, so the growth rate is slow, and the structure of the scion connecting the stock is fragile. When encountering strong winds, it is easy to break or pull the side branches. The slow growth rate will also make The scion taken from the mother tree has the disadvantage that it is not easy to mass produce when it is grafted again to the mother tree that replicates the same excellent gene.

Because the existing method of grafting the scion of fruit trees onto a single rootstock has the problems of slow growth rate, fragile root structure of the scion, and difficulty in mass production. For this reason, the present invention uses two or more rootstocks to graft the scions of fruit trees to form a fruit tree with multiple rootstocks, and uses its side branches to bridge two or more rootstocks to form a mother tree with the same gene. It is difficult to achieve a strong root structure of the mother tree. The effect of breaking and growing faster, which is conducive to mass production.

In order to achieve the above objective, the present invention provides a method for abutting multiple rootstocks of fruit trees. The steps of the method include: preparing rootstock pots: planting two or more rootstocks on the soil of one rootstock potting, and planting two or more rootstocks at the same height at the top of the rootstocks. The inner side is cut to form a grafted end exposing the cambium; the grafting to form a mother tree: Take a fruit tree with a branch bud or leaf side branch as the scion, and cut two or more grafting ends around the scion to form two or more exposed forms The grafting part of the layer, the two or more grafting ends are fixed to the two or more grafting parts in a manner of mutual cambium close to each other. After two or more rootstocks and the scion are healed, a mother tree is formed. After the mother tree grows, it has One main stem and one or more side branches connected to the main stem; prepare another rootstock potted plant: plant two or more adjacent rootstocks in the soil of the other rootstock potting, each on the inner side of the top equal heights Cut to form an abutting end that exposes the cambium; complete the abutment preparation: use one of the branches of the mother tree as the second abutting scion, and cut around the middle section of the second scion to form two or more abutments that respectively expose the cambium Part, the second scion is drawn closer to the two or more abutting rootstocks, and the two or more abutting ends are fixed to the two or more abutting roots of the second scion in a manner that the cambium abuts each other. Finish the docking preparation.

Furthermore, the present invention performs a healing cutting step after completing the step of docking preparation, which is after the two or more docking rootstocks and the second scion are healed, the second scion is cut below the healing site. Complete another mother tree in the next section.

Furthermore, in the present invention, after the step of grafting and forming the mother tree, a step of pruning the trunk is performed, which is to cut the upper section of the trunk of the mother tree so that the height of the mother tree after growth is always lower than 80 cm, and only the mother tree is allowed The branches grow naturally.

Preferably, the present invention is based on the surroundings of the two or more grafting ends and the two or more grafting parts, as well as between the two or more abutting ends and the two or more abutting parts. Wrap a grafting tape around each of them to fix.

The present invention also provides a mother tree potted plant, in which a pot is provided with a soil, two or more rootstocks are planted in the soil, and a scion is healedly connected to the inner side of the top equal heights of the two or more rootstocks. The scion is derived from The fruit tree also includes a main trunk and one or more side branches connected with the main trunk after growth.

Furthermore, the present invention forms a shearing portion at the bottom end of the scion lower than the healing site.

Through the method of the present invention, two or more rootstocks can be grafted with scions from fruit trees with excellent genes to form a mother tree with the same excellent genes, and the mother tree can be used repeatedly with rootstock potted plants with more than two rootstocks. Form another mother tree of the same gene. The effect of the present invention is that no matter the parent tree after grafting or docking is completed, there are more than two rootstocks to supply water and nutrients, the foundation is stable and not easy to break, it can resist strong winds, and it is beneficial to pull the side branches and abut two or more docking rootstocks when docking. Sufficient and even supply of nutrients and water not only allows the mother tree to grow at a better speed, it is also not easy to cause the trunk to skew, and the original mother tree still supplies the second scion nutrient when docking, which can improve the success of docking healing Rate, better mother tree growth speed and higher docking success rate enable the implementation of this method to have better mass production of mother trees.

In order to understand the technical features and practical effects of the present invention in detail, and implement it according to the content of the specification, the preferred embodiment shown in the figure is further described in detail as follows.

Please refer to the step flowchart of the preferred embodiment of the present invention as shown in FIG. 1. The present invention provides a method for docking multiple rootstocks of fruit trees. The steps of the method include:

(S01) Preparation of rootstock potted plants: as shown in Figure 2, prepare a rootstock potted plant A, the rootstock potted plant A is provided with a pot 10, a soil 11 is provided in the pot 10, two rootstocks 12 are planted on the soil 11, and the two rootstocks The top ends of the two rootstocks 12 are trimmed to the same height, and the two rootstocks 12 are cut to form a grafting end 13 that exposes the cambium B on the opposite inner sides of the tops of the two rootstocks 12 at the same height.

(S02) Grafting to form a mother tree: Take a fruit tree with branch buds or leaf side branches as the scion 14. Preferably, the scion 14 comes from a fruit tree with good genetic quality, and the two grafting ends 13 are placed on opposite sides of the scion 14 The side cutting forms two grafting parts 15 respectively exposing the forming layer B. Each grafting part 15 is cut into a shape corresponding to the size of each grafting end 13 and corresponding to the respective forming layer B. The two grafting ends 13 are mutually formed into layer B. Affix to the two grafting parts 15 in a close manner, and use a grafting tape C to wrap around the two grafting ends 13 and the two grafting parts 15 for fixation. The grafting tape C seals the surrounding and fixes to prevent rainwater and mosquito bites from healing The position D affects the healing quality of the two rootstocks 12 and the scion 14. When the two rootstocks 12 and the scion 14 are healed, a mother tree 20 is formed. After the mother tree 20 grows, it has a main stem 21 and more than one side branches connected to the main stem 21 22. The aforementioned side branches 22 connected to the main stem 21 include directly or indirectly connected to the main stem 21; since the mother tree 20 uses two rootstocks 12 to provide water and nutrients at the same time, the mother tree 20 has the original excellent genes of the scion 14, The scion 14 supported by the two rootstocks 12 is stronger and not easy to break, which facilitates the subsequent docking procedure. The sufficient nutrient and water supply allows the mother tree 20 to have better nutrition and grow faster, and the dual rootstocks 12 support and transport nutrients Therefore, the support and nutrient sources of the main stem 21 rows of the mother tree 20 during the growth of photosynthesis are not skewed to one side on average.

(S03) Pruning the trunk: As shown in Figure 3, during the growth of the mother tree 20, the upper section of the trunk 21 of the mother tree 20 is continuously cut, so that the height of the mother tree 20 after growth is always lower than 80 cm. Only the side branches 22 of the mother tree 20 are allowed to grow naturally, so that the height of the mother tree 20 is not too high.

(S04) Prepare another rootstock potted plant: as shown in Figure 4, prepare another rootstock potted plant A. This rootstock potted plant A is provided with a pot 10, a soil 11 is provided in the pot 10, and two adjacent rootstocks are planted on the soil 11 16. Trim the heights of the two abutting rootstocks 16 to the same height, and cut the opposite inner sides of the tops of the two abutting rootstocks 16 at the same height to form abutting ends 17 that expose the cambium B.

(S05) Preparation for docking: As shown in Figures 3 and 4, one of the branches 22 of the mother tree 20 is used as the second scion 18 for docking. If the upper section of the trunk 21 of the mother tree 20 is often trimmed, the height will not be Too high. When the second scion 18 is used to abut the two adjacent rootstocks 16 of another rootstock pot A, there is no need to use additional equipment to raise the position of the two adjacent rootstocks 16, but can be close to the ground Apply; cut the two opposite sides around the middle section of the second scion 18 to form two abutting portions 181 that respectively expose the cambium B, and each abutting portion 181 is cut into the same size as the abutting ends 17 and their respective cambium B With the corresponding shape, the second scion 18 is drawn closer to the two abutting rootstocks 16, and the two abutting ends 17 are abutted against the two abutting portions 181 in a manner that the cambium B abuts each other, and the other is grafted The belt C is wound around the two abutting ends 17 and the two abutting portions 181 and is fixed. The grafting belt C seals the surrounding fixation to prevent rain and mosquito bites from the healing area D and affect the two abutting rootstocks 16 and the second The healing quality of scion 18 completes the docking preparation.

(S06) Healing cutting: After the two adjacent rootstocks 16 and the second scion 18 are healed, cut the lower section of the second scion 18 lower than the healing place D to form a cut portion D1, and complete another mother tree 20A, this mother tree The gene of 20A is the same as the aforementioned mother tree 20, and the second scion 18 of this mother tree 20A will also include the main stem and one or more side branches directly or indirectly connected to the main stem after growth. The only difference is that the second scion 18 is in the lower The cut part D1 is formed at the bottom end of the healing site D; this mother tree 20A also has the original mother tree 20 supported by double rootstocks to make the scion strong, the growth process is relatively average, the main stem will not skew to one side, and two adjacent rootstocks 16 are provided The characteristics of sufficient nutrients and water so that it grows faster, and the second scion 18 can still be absorbed during the healing process. The nutrient supplied by the original mother tree 20 has a higher success rate of healing by leaning, and can efficiently cultivate more mother trees and have the effect of mass-producing mother trees with the same gene.

In addition to the aforementioned preferred embodiment of the present invention, in the step of preparing potted rootstocks, in addition to planting two rootstocks 12 on the soil 11, in another preferred embodiment, two or more rootstocks can also be planted on the soil 11. The rootstocks 12, for example, three rootstocks 12 planted around, the heights of the three rootstocks 12 are trimmed to the same height, and the tops of the three rootstocks 12 are cut on the opposite inner sides of the same height to form the grafting ends 13; and In the step of grafting to form a mother tree, two or more grafting ends 13 are cut around the scion 14 to form two or more grafting parts 15, such as three grafting parts 15, and The grafting ends 13 of the two are attached to the two or more grafting parts 15 in a manner that the cambium B is close to each other, and then the grafting tape C is wound around all the grafting ends 13 and all the grafting parts 15 and fixed, When two or more rootstocks 12 and the scion 14 are healed, the mother tree 20 is formed, and the mother tree 20 has roots formed by more than two rootstocks 12.

Similarly, in the step of preparing another rootstock pot plant, in addition to only planting two adjacent rootstocks 16 in the soil 11, it is also possible to plant more than two adjacent rootstocks 16 in the soil 11 of the other rootstock pot A, such as surrounding Plant the three abutting rootstocks 16, trim the heights of the three abutting rootstocks 16 to the same height, and then cut the three abutting rootstocks 16 on the opposite inner sides of the top equal heights to form the abutting ends 17; and In the step of completing the abutting preparations, two or more abutting ends 17 are cut around the middle section of the second scion 18 to form more than two abutting portions 181, for example, three abutting portions 181 , Draw the second scion 18 closer to two or more abutting rootstocks 16, and abut the two or more abutment ends 17 on the two or more abutment portions 181 in a manner that the cambium B abuts each other, Then another grafting tape C is wrapped around all the abutting ends 17 and all the abutting parts 181 and is fixed to complete the abutment preparation; after two or more abutting rootstocks 16 and the second scion 18 are healed, cut off After the second scion 18 is lower than the lower part of the healing site D to form the cut part D1, another mother tree 20A is completed, and the gene of this mother tree 20A is the same as the mother tree 20 having two or more rootstocks 12 described above.

The other preferred embodiment described above is to modify the number of planting rootstocks 12 and abutting rootstocks 16 in the original preferred embodiment. The remaining steps of this other preferred embodiment include grafting and abutting rootstocks 12 and 16 The effects that can be achieved by forming the mother tree 20 and another mother tree 20A are the same as those described in the original preferred embodiment.
