[0002] Hybrid breeding refers to the mating of two or more pear trees with different traits through artificial pollination to produce new hybrids. Through multiple generations of selection and reasonable pairing of offspring, new varieties with excellent traits are gradually formed. The advantage of hybrid breeding is that it can produce excellent varieties and can adapt to growing in a variety of environmental conditions, but the disadvantage of hybrid breeding is also obvious, that is, the cycle is relatively long, usually at least 5-10 years, or even longer. The early fruiting of pear hybrid seedlings is a key issue limiting pear hybrid breeding, and there is no method for accelerating the early fruiting of hybrid branches of pear trees.

[0003] The present invention uses the technical features of growing fruiting branches from terminal buds and providing fruiting nutrition from pear rootstocks to effectively explore and study the technical problem of making hybrid branches of pear trees bear fruit, which usually takes at least 5 to 10 years. The statements here only provide background technology related to the present invention and do not necessarily constitute prior art.

The object of the present invention is a device for cultivating hybrid branches of pear trees. The object of the present invention is a method for cultivating hybrid branches of pear trees.

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

[0006] To achieve the above object, the technical solution adopted by the present invention is: a method for accelerating early fruiting of hybrid branches of pear trees, the steps of which are: grafting the terminal buds of the hybrid branches of the second-year pear trees onto perennial pear rootstocks.

[0007] The design of grafting the apical buds of the second-year hybrid branches of pear trees onto perennial pear rootstocks enabled the apical buds to grow into fruiting branches, and the pear rootstocks provided the nutrients for fruiting. This solved the technical problem of making the hybrid branches of pear trees bear fruit, which usually takes at least 5 to 10 years. As a result, hybrid fruiting branches of pear trees were obtained in the third year.

[0008] The present invention has been designed, and the steps are: 1. Processing in the current year: Select mature hybrid pear tree seeds, soak the full hybrid pear tree seeds in 4.8-5.2% sodium hypochlorite solution for 15-20 minutes to obtain sterilized hybrid pear tree seeds. Rinse the sterilized hybrid pear tree seeds with clean water for 3-5 times, and soak the rinsed hybrid pear tree seeds in clean water for 22-26 minutes to obtain expanded hybrid pear tree seeds. The seed coat of the swollen hybrid pear tree seeds is artificially removed, and the embryo of the swollen hybrid pear tree seeds is kept intact to obtain peeled hybrid pear tree seeds, and the peeled hybrid pear tree seeds are placed on sterilized gauze in a plastic basin, and the plastic basin is covered with a plastic wrap, and breathing holes are pierced in the plastic wrap, and the plastic basin is placed in a constant temperature incubator, and the temperature in the constant temperature incubator is maintained at 22-26° C., and germinated hybrid pear tree seeds are obtained after 70-74 hours, and hybrid pear tree seedlings are obtained after 166-170 hours. Vermiculite and nutrient soil are mixed in a weight ratio of 1:1.1-1.2 to obtain a culture matrix, the culture matrix is ​​spread in a culture pot, the culture matrix in the culture pot is sprayed with water using a watering can, the hybrid pear tree seedlings are planted on the culture matrix, a layer of the culture matrix is ​​covered on the hybrid pear tree seedlings, the culture pot is placed in a light culture box, the hybrid pear tree seedlings are cultivated and managed, and the hybrid pear tree seedlings of the current year are obtained. 2. Processing in the second year: In April of the second year, the hybrid pear tree seedlings with soil balls were transplanted into the planting soil, covered with plastic film, and the planting soil was fertilized and watered. When the hybrid pear tree seedlings reached 1.8-2.2 meters, hybrid pear tree branches were obtained. 3. Processing in the third year: In the spring of the third year, collect the 20-30 cm terminal buds at the top of the hybrid branches of the pear tree, graft them at a high position onto the pear rootstock, and use the pulling branch management method to accelerate the early fruiting of the fruiting branches.

[0009] The present invention has been designed, and the steps are: Level 1 acceleration speeds up seed germination: In the year of hybridization, when the hybrids are mature, collect the hybrid fruits to obtain seeds, clean the seeds, soak them in 5% sodium hypochlorite solution for 10 minutes, rinse them with clean water 3 times, and then soak them in clean water for 24 hours. Use artificial methods to remove the seed coat, and do not damage the embryo of the hybrid seeds. Place the hybrid seeds with the seed coat removed evenly on the sterilized gauze, and place the gauze in a square plastic basin. Pay attention to moisturizing to prevent the seeds from drying out. Cover the square plastic basin with plastic wrap, reserve small holes to keep it breathable, and place the plastic basin in a constant temperature incubator at 24°C. The seeds will germinate in about 3 days. Second level acceleration accelerates the growth of hybrid seedlings: After the hybrid seedlings have grown for 7 days, they are transplanted into the nutrient soil. First, mix the nutrient soil and vermiculite in a 1:1 ratio, transfer the mixed nutrient soil to the culture pot, use a watering can to water the nutrient soil in the culture pot, transfer the germinated hybrid seedlings to the culture pot, and then cover them with a layer of mixed nutrient soil to completely cover the germinated seedlings. Transfer the nutrient pot to the light incubator and water it in time to accelerate the growth of the seedlings. After 14 days, most of the seedlings have grown 2 true leaves. After continuing to grow for 14 days, the seedlings can be transplanted in time. Level 3 acceleration results: In April of the second year after hybridization, the hybrid seedlings are transplanted into the field with soil balls, covered with film, and the supply of fertilizer and water is strengthened to ensure that the height of the hybrid seedlings reaches more than 2 meters when the leaves fall. In the spring of the third year, the top 20-30 cm buds of the hybrid seedlings are collected and grafted onto pear rootstocks. Management continues to be strengthened, and rapid fruiting is promoted through scientific research pulling and other means. Fruiting can be achieved in 4-5 years, which is 4-5 years shorter than conventional management.
