Description

Technical Field

[0001] This invention relates to a method, cultivation device, and approach for accelerating early fruiting, and more particularly to a method, cultivation device, and approach for accelerating early fruiting of pear hybrid branches. Background Technology

[0002] Hybrid breeding refers to the process of artificially pollinating two or more pear trees with different traits to produce new hybrids. Through multiple generations of selection and rational pairing of offspring, new varieties with superior traits are gradually formed. The advantage of hybrid breeding is that it can produce superior varieties and adapt to various environmental conditions. However, the disadvantages of hybrid breeding are also obvious, namely that the cycle is relatively long, usually requiring at least 5-10 years or even longer. Early fruiting of pear hybrid seedlings is a key issue limiting pear hybrid breeding, and there is still no method to accelerate early fruiting of pear hybrid branches.

[0003] This invention, through its technical features of allowing terminal buds to grow into fruiting branches and utilizing pear rootstock to provide nutrients for fruiting, effectively explores and studies the technical problem of how pear hybrid branches typically require at least 5-10 years to bear fruit. The statements herein provide only background information related to this invention and do not necessarily constitute prior art. Based on the technical disclosure provided by the applicant on December 22, 2024, which addresses practical technical problems encountered during the work process, and the existing technical problems, technical features, and technical effects in similar patent documents and background information obtained through retrieval, the technical solution of this invention is proposed. Summary of the Invention

[0004] The subject of this invention is a method for accelerating and promoting early fruiting in hybrid branches of pear trees. The subject of this invention is a device for cultivating hybrid branches of pear trees. The subject of this invention is a method for cultivating hybrid branches of pear trees.

[0005] In order to overcome the above-mentioned technical shortcomings, the purpose of this invention is to provide a method, cultivation device and method for accelerating the early fruiting of pear hybrid branches, thereby achieving the goal of obtaining pear hybrid fruiting branches in the third year.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a method for accelerating and promoting early fruiting of pear hybrid branches, the steps of which are: grafting the terminal bud of a second-year pear hybrid branch onto a perennial pear rootstock.

[0007] By designing a method to graft the terminal bud of a second-year pear hybrid branch onto a perennial pear rootstock, the terminal bud was allowed to grow into a fruiting branch, and the pear rootstock was used to provide nutrients for fruiting. This solved the technical problem of pear hybrid branches typically taking at least 5-10 years to bear fruit, thus enabling the production of pear hybrid fruiting branches in the third year.

[0008] The present invention is designed, and its steps are as follows: I. Handling in the current year: Mature hybrid pear seeds were selected, and plump seeds were soaked in a 4.8-5.2% sodium hypochlorite solution for 15-20 minutes to obtain sterilized hybrid pear seeds. Rinse the disinfected hybrid pear seeds 3-5 times with clean water, then soak them in clean water for 22-26 minutes to obtain swollen hybrid pear seeds. The swollen hybrid pear seeds are manually de-coated while preserving the intact embryo. These de-coated seeds are then placed on sterilized gauze in a plastic container, covered with plastic wrap (with ventilation holes pricked in the wrap), and placed in a constant-temperature incubator at 22-26°C. Germination occurs in 70-74 hours, and seedlings are obtained in 166-170 hours. Mix vermiculite and nutrient soil at a weight ratio of 1:1.1-1.2 to obtain a culture medium. Spread the culture medium evenly in a culture pot and spray it with water. Plant the hybrid pear seedlings on the culture medium, cover them with another layer of culture medium, and place the culture pots in a light incubator for cultivation and management to obtain hybrid pear seedlings for the current year. II. Handling in the second year: In April of the following year, the hybrid pear seedlings, with their root balls intact, were transplanted into the planting soil. The seedlings were then covered with plastic film, and the planting soil was fertilized and watered. Once the seedlings reached 1.8-2.2 meters in height, hybrid pear branches were obtained. III. Handling in the third year: In the spring of the third year, the terminal buds of the hybrid branches of pear trees, 20-30 cm long, are collected and grafted high onto the pear rootstock. The fruiting branches that grow from the terminal buds are managed by branch pulling to accelerate and promote early fruiting.

[0009] The present invention is designed, and its steps are as follows: Level 1 acceleration speeds up seed germination: In the year of hybridization, when the hybrid seeds mature, collect the hybrid fruits to obtain seeds. Clean the seeds thoroughly, soak them in a 5% sodium hypochlorite solution for 10 minutes, rinse them three times with clean water, and then soak them in clean water for 24 hours. Remove the seed coat manually, taking care not to damage the embryo of the hybrid seed. Place the seed coat-removed hybrid seeds evenly on a piece of sterilized gauze, and place the gauze in a square plastic basin, keeping it moist to prevent the seeds from drying out. Cover the square plastic basin with plastic wrap, leaving small holes for ventilation. Place the plastic basin in a constant temperature incubator at 24℃. The seeds will germinate in about 3 days. Secondary acceleration accelerates the growth of hybrid seedlings: Seven days after the hybrid seedlings have grown, they are transplanted into nutrient soil. First, mix the nutrient soil and vermiculite in a 1:1 ratio. Transfer the mixed nutrient soil to the seedling pots and water it thoroughly with a spray bottle. Transfer the germinated hybrid seedlings to the seedling pots, then cover them completely with another layer of mixed nutrient soil. Transfer the seedling pots to a light-cured incubator and water them as needed to accelerate growth. After 14 days, most seedlings will have grown two true leaves. Continue growing for another 14 days, and the seedlings are ready for transplanting. Level 3 acceleration result: In April of the second year after hybridization, the hybrid seedlings are transplanted to the ground with a soil ball, covered with mulch, and the supply of fertilizer and water is strengthened to ensure that the hybrid seedlings reach a height of more than 2 meters by the time the leaves fall. In the spring of the third year, the terminal buds of the hybrid seedlings, 20-30 cm long, are collected and grafted onto pear rootstock. Management is further strengthened, and rapid fruiting is promoted through scientific branch pulling and other methods. Fruiting can be achieved in 4-5 years, which is 4-5 years shorter than conventional management.

When the planting depth is suitable, rotate the screw within the receiving hole I, causing the screw flange to act on the outer end face of the plate section. Soil is backfilled into the tree pit. The outer end of the wire bundle is connected to the water and fertilizer application pipe. When the hybrid pear seedling comes into contact with the plastic film, the woven rope is separated from the plastic film, and the plastic film is removed from the tube base, allowing the hybrid pear seedling to continue growing in the tube to obtain hybrid pear branches. When it is necessary to train the hybrid pear branches, the training rod is placed between the ear base and the hybrid pear branch that needs to be trained. One end of the training rod is tied to the hybrid pear branch that needs to be trained, and the other end of the training rod is connected to the ear base with a bolt and nut.

[0044] The technical effect of the above solution is that it enables the cultivation of hybrid pear seedlings with well-developed root systems and robust hybrid pear branches.

Handling in the current year: Mature hybrid pear seeds were selected, and plump seeds were soaked in a 4.8-5.2% sodium hypochlorite solution for 20 minutes to obtain sterilized hybrid pear seeds. The disinfected hybrid pear seeds were rinsed five times with clean water. The rinsed seeds were then soaked in clean water for 26 minutes to obtain swollen hybrid pear seeds. The swollen hybrid pear seeds were manually peeled while preserving the intact embryo.

Germination occurred after 74 hours, and seedlings were obtained after 170 hours. Mix vermiculite and nutrient soil at a weight ratio of 1:1.2 to obtain a culture medium. Spread the culture medium evenly in a culture pot and spray it with water. Plant the hybrid pear seedlings on the culture medium, cover them with another layer of culture medium, and place the culture pots in a light incubator for cultivation and management to obtain hybrid pear seedlings for the current year. II. Handling in the second year: In April of the following year, the hybrid pear seedlings, with their root balls intact, were transplanted into the planting soil.

[0059] The third supporting example of one of the first embodiments of the present invention has the following steps: I.

The fruiting branches that grow from the terminal buds are managed by branch pulling to accelerate and promote early fruiting.

[0060] In this embodiment, the pear hybrid variety is set as Dailu.

[0061] A method for accelerating and promoting early fruiting of pear hybrid branches, the second embodiment of the present invention, comprises the following steps: Level 1 acceleration speeds up seed germination: In the year of hybridization, when the hybrid seeds mature, collect the hybrid fruits to obtain seeds. Clean the seeds thoroughly, soak them in a 5% sodium hypochlorite solution for 10 minutes, rinse them three times with clean water, and then soak them in clean water for 24 hours. Remove the seed coat manually, taking care not to damage the embryo of the hybrid seed. Place the seed coat-removed hybrid seeds evenly on a piece of sterilized gauze, and place the gauze in a square plastic basin, keeping it moist to prevent the seeds from drying out. Cover the square plastic basin with plastic wrap, leaving small holes for ventilation. Place the plastic basin in a constant temperature incubator at 24℃. The seeds will germinate in about 3 days. Secondary acceleration accelerates the growth of hybrid seedlings: Seven days after the hybrid seedlings have grown, they are transplanted into nutrient soil. First, mix the nutrient soil and vermiculite in a 1:1 ratio. Transfer the mixed nutrient soil to the seedling pots and water it thoroughly with a spray bottle. Transfer the germinated hybrid seedlings to the seedling pots, then cover them completely with another layer of mixed nutrient soil. Transfer the seedling pots to a light-cured incubator and water them as needed to accelerate growth. After 14 days, most seedlings will have grown two true leaves. Continue growing for another 14 days, and the seedlings are ready for transplanting. Level 3 acceleration result: In April of the second year after hybridization, the hybrid seedlings are transplanted to the ground with a soil ball, covered with mulch, and the supply of fertilizer and water is strengthened to ensure that the hybrid seedlings reach a height of more than 2 meters by the time the leaves fall. In the spring of the third year, the terminal buds of the hybrid seedlings, 20-30 cm long, are collected and grafted onto pear rootstock. Management is further strengthened, and rapid fruiting is promoted through scientific branch pulling and other methods. Fruiting can be achieved in 4-5 years, which is 4-5 years shorter than conventional management.

[0087] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0088] A method for cultivating hybrid pear tree branches includes the following steps: placing expanded hybrid pear tree seeds on the outer end of a strip 3; placing a plastic film 2 on the upper open end of a cylinder 11; wrapping a textile rope around the plastic film 2 and tying it with the end of the rope; installing the plastic film 2 on a cylinder base 1; soaking a ring pad 4 in clean water until it is saturated with water; placing the ring pad 4 into the lower end of the cylinder 11; moving the plate 51 upwards on the cylinder 11 so that the inner side of the upper end face of the cylinder shell 7 contacts the cylinder base 1 and the ring pad 4; rotating the screw 6 in the receiving hole Ⅰ14; and having the flange of the screw 6 act on the outer end face of the plate 51, thus placing the expanded hybrid pear tree seeds in the cylinder 11; and placing the cylinder 11 in a constant temperature incubator to allow the expanded hybrid pear tree seeds to germinate and root, resulting in hybrid pear tree seedlings. Dig a pit in the planting soil to obtain a tree pit. Rotate the screw 6 in the opposite direction within the receiving hole I14 to separate the flange of the screw 6 from the outer end face of the plate 51. Move the plate 51 downwards on the cylinder 11, separating the inner side of the upper end face of the cylinder 7 from the cylinder seat 1 and the ring gasket 4. Remove the ring gasket 4 from the lower end port of the cylinder 11 and soak it in rooting liquid until it is saturated with the liquid. Place the ring gasket 4 into the lower end port of the cylinder 11, so that it fits over the roots of the hybrid pear seedling. Install the outer end of the wire bundle 8 between the transverse parts of the strip 52. Place the hybrid pear seedling, cylinder 7, and wire bundle 8 into the tree pit. Place the cylinder 7 on the bottom of the tree pit and coil the wire bundle 8 in the pit. Move the cylinder 11 on the plate 51 to adjust its height. The planting depth of the pear seedlings in the tree pit is adjusted. When the planting depth of the hybrid pear seedlings in the tree pit is at a suitable value, the screw 6 is rotated in the receiving hole I14, so that the flange of the screw 6 acts on the outer end face of the plate 51, and the soil is backfilled into the tree pit. The outer end of the wire bundle 8 is connected to the water and fertilizer application pipe. When the hybrid pear seedlings come into contact with the plastic film 2, the textile rope is separated from the plastic film 2, and the plastic film 2 is removed from the cylinder seat 1, so that the hybrid pear seedlings continue to grow in the cylinder 11 to obtain hybrid pear branches. When it is necessary to perform branch pulling treatment on the hybrid pear branches, the branch pulling rod is placed between the ear seat 12 and the hybrid pear branches that need to be pulled. One end of the branch pulling rod is tied together with the hybrid pear branches that need to be pulled, and the other end of the branch pulling rod is connected to the ear seat 12 by bolts and nuts.

[0089] In verifying this invention, the inventors abandoned the existing technical features that typically require at least 5-10 years for pear hybrid branches to bear fruit. They first proposed a technical feature where the terminal bud grows into a fruiting branch and the pear rootstock provides the nutrients for fruiting. This resulted in the first unexpected technical effect: enabling cross-plant growth of pear hybrid fruiting branches and eliminating the influence of a weak rootstock. The second unexpected technical effect: allowing the roots of the expanding hybrid pear seeds to develop freely and accelerating the growth of hybrid pear seedlings in active soil, thus improving the cultivation effect of the terminal buds of the pear hybrid branches. The third unexpected technical effect: enabling the branch to develop from the rootstock and the branch... The support of the expanded hybrid pear seeds by the film 3 improves their germination and rooting stability, resulting in a fourth unexpected technical effect: the plastic film 2 and the ring pad 4 provide a sealed environment for the expanded hybrid pear seeds to germinate and root, improving their germination and rooting effect. This also results in a fifth unexpected technical effect: the adjustable height support of the cylinder base 1 by the movable frame 5 and the screw 6 allows for precise adjustment of the planting depth of the hybrid pear seedlings. Finally, the improvement of the planting soil by the cylinder shell 7 and the wire harness strip 8 enhances the soil's aeration and fertilization performance, thereby improving the growth of the hybrid pear seedlings.

[0090] In the second embodiment of the present invention, the cylinder seat 1 and the strip 3 are connected to each other in a manner that allows for the release of downward extension of the roots of the pre-expanded hybrid pear seed.

[0091] In this embodiment, the strip 3 is connected to the cylinder base 1 in a manner that suspends the expanded hybrid pear seeds in mid-air.

[0092] In this embodiment, a first accessory device is also included and disposed on the cylinder base 1. The first accessory device is configured to include a plastic film 2 and a ring gasket 4.

[0093] In this embodiment, a second accessory device is also included and is disposed on the cylinder base 1. The second accessory device is configured to include a movable frame 5, a screw 6, a cylinder shell 7, and a wire harness 8.

[0094] The second embodiment of the present invention is based on the first embodiment. In the second embodiment of the present invention, the steps are as follows: the cylinder seat 1 provides internal support for the strip 3, the strip 3 suspends the expanded hybrid pear seed, and the space reserved for the expansion of the hybrid pear seed root system to extend downward is reserved.

[0095] The second embodiment of the present invention is based on the first embodiment.

[0096] This invention has the following characteristics: 1. By designing the grafting of the terminal bud of the second-year pear hybrid branch to the perennial pear rootstock, the terminal bud was allowed to grow into a fruiting branch, and the pear rootstock was used to provide fruiting nutrition. This solved the technical problem of the pear hybrid branch, which usually takes at least 5-10 years to bear fruit. Therefore, pear hybrid fruiting branches were obtained in the third year.

[0097] 2. Due to the design of the cylinder base 1 and the strip 3, the cylinder base 1 provides internal support for the strip 3, and the strip 3 allows the expanded hybrid pear seeds to be suspended in the air, thus reserving space for the roots of the expanded hybrid pear seeds to extend downwards. This solves the technical problem of placing the expanded hybrid pear seeds at the bottom of the container, thereby improving the rooting and germination effect of the hybrid pear seeds.

[0098] 3. Due to the design of plastic film 2 and ring pad 4, the environmental requirements for germination and rooting of the expanded hybrid pear seeds are met.

[0099] 4. The design of the movable frame 5, screw 6, cylindrical shell 7, and wire harness 8 has achieved the environmental requirements for the growth of hybrid pear seedlings.

[0100] 5. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0101] 6. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.

[0102] Other technical features that are the same as or similar to the technical features of growing from terminal buds into fruiting branches and receiving fruiting nutrition from pear rootstock are also embodiments of the present invention. Furthermore, the technical features of the embodiments described above can be combined in any way. In order to meet the requirements of the Patent Law, the Implementing Regulations of the Patent Law and the Examination Guidelines, embodiments of all possible combinations of the technical features in the above embodiments will no longer be described.

[0103] The above embodiments are merely one implementation of the method, cultivation device, and method for accelerating early fruiting of pear hybrid branches provided by the present invention. Other modifications to the solution provided by the present invention, adding or reducing the components or steps therein, or applying the present invention to other technical fields similar to the present invention, all fall within the protection scope of the present invention.

I. Handling in the current year: Mature hybrid pear seeds were selected, and plump seeds were soaked in a 4.8-5.2% sodium hypochlorite solution for 15-20 minutes to obtain sterilized hybrid pear seeds. Rinse the disinfected hybrid pear seeds 3-5 times with clean water, then soak them in clean water for 22-26 minutes to obtain swollen hybrid pear seeds. The swollen hybrid pear seeds are manually de-coated while preserving the intact embryo. These de-coated seeds are then placed on sterilized gauze in a plastic container, covered with plastic wrap (with ventilation holes pricked in the wrap), and placed in a constant-temperature incubator at 22-26°C. Germination occurs in 70-74 hours, and seedlings are obtained in 166-170 hours. Mix vermiculite and nutrient soil at a weight ratio of 1:1.1-1.2 to obtain a culture medium. Spread the culture medium evenly in a culture pot and spray it with water. Plant the hybrid pear seedlings on the culture medium, cover them with another layer of culture medium, and place the culture pots in a light incubator for cultivation and management to obtain hybrid pear seedlings for the current year. II. Handling in the second year: In April of the following year, the hybrid pear seedlings, with their root balls intact, were transplanted into the planting soil. The seedlings were then covered with plastic film, and the planting soil was fertilized and watered. Once the seedlings reached 1.8-2.2 meters in height, hybrid pear branches were obtained. III. Handling in the third year: In the spring of the third year, the terminal buds of the hybrid branches of pear trees, 20-30 cm long, are collected and grafted high onto the pear rootstock. The fruiting branches that grow from the terminal buds are managed by branch pulling to accelerate and promote early fruiting.

8. A method for accelerating and promoting early fruiting of pear hybrid branches cultivated according to the cultivation method described in claim 6, characterized in that: The steps of the method for accelerating and promoting early fruiting of pear hybrid branches are as follows: Level 1 acceleration speeds up seed germination: In the year of hybridization, when the hybrid seeds mature, collect the hybrid fruits to obtain seeds. Clean the seeds thoroughly, soak them in a 5% sodium hypochlorite solution for 10 minutes, rinse them three times with clean water, and then soak them in clean water for 24 hours. Remove the seed coat manually, taking care not to damage the embryo of the hybrid seed. Place the seed coat-removed hybrid seeds evenly on a piece of sterilized gauze, and place the gauze in a square plastic basin, keeping it moist to prevent the seeds from drying out. Cover the square plastic basin with plastic wrap, leaving small holes for ventilation. Place the plastic basin in a constant temperature incubator at 24℃. The seeds will germinate in about 3 days. Secondary acceleration accelerates the growth of hybrid seedlings: Seven days after the hybrid seedlings have grown, they are transplanted into nutrient soil. First, mix the nutrient soil and vermiculite in a 1:1 ratio. Transfer the mixed nutrient soil to the seedling pots and water it thoroughly with a spray bottle. Transfer the germinated hybrid seedlings to the seedling pots, then cover them completely with another layer of mixed nutrient soil. Transfer the seedling pots to a light-cured incubator and water them as needed to accelerate growth. After 14 days, most seedlings will have grown two true leaves. Continue growing for another 14 days, and the seedlings are ready for transplanting. Level 3 acceleration result: In April of the second year after hybridization, the hybrid seedlings are transplanted to the ground with their root balls, covered with mulch, and fertilized and watered with increased care to ensure that the seedlings reach a height of over 2 meters by leaf fall. In the spring of the third year, the terminal buds (20-30 cm from the top) of the hybrid seedlings are collected and grafted onto pear rootstock. Management continues to be strengthened, and rapid fruiting is promoted through scientific branch training and other methods. Fruiting can begin in 4-5 years, which is 4-5 years shorter than conventional management. The pear hybrid varieties were set as Daisu, Daicui, or Dailu.
