Problems solved by technology

[0005] The problem solved by the present invention is to provide a method for cultivating apple dwarfed self-rooted multi-branched seedlings. The produced apple seedlings grow thickly and uniformly, with 10 to 15 side branches in suitable positions, which overcomes the disadvantages of existing seedling cultivation methods. The quality of seedlings is poor, the seedlings are thin and weak, and the survival rate of the garden is low

Embodiment 1

[0043] The cultivation of embodiment 1 Changfu No. 2 grafted on the dwarf apple seedlings on the M9 stock

[0044] In Buwang Village, Dazhuang Town, Wugong, Shaanxi Province, 3 mu of flat land with good drainage was selected to build a seedbed for the cultivation of apple dwarf rootstock M9. The seedbed was divided into strips with a width of 80 cm. One row was used to plant rootstocks, and the planting row could be planted with 3 rows of rootstocks. , choose a strong M9 rootstock with well-developed root system as the mother plant, with a row spacing of 30cm, and the plants are handed over from front to back, and planted at an angle of 30 degrees to the ground. After germination, the planted rootstock is flattened and fixed with wooden strips;

[0045]When the dwarf rootstock M9 new branch grows to 50cm, bury the dwarf rootstock M9 new branch with fresh sawdust, and the height of burial is 20cm. In March of the next year, before spring germination, the rootstock is cut off fro...

Embodiment 2

[0050] The cultivation of the dwarf apple seedlings grafted on the G41 stock of embodiment 2 Royal Gala

[0051] In Wuhuisi Village, Shoushan Town, Meixian County, Shaanxi Province, 5 mu of well-drained river beach was selected to build a seedbed for the cultivation of apple dwarf rootstock G41. The seedbed was divided into strips with a width of 80 cm. One row was used to plant rootstocks, and the planting row could be planted in 3 rows. For rootstocks, choose strong G41 rootstocks with well-developed root systems, with a row spacing of 30 cm, and the plants are planted at an angle of 30 degrees to the ground. After germination, the planted rootstocks are flattened and fixed with wooden strips;

[0052] When the new branch of dwarf rootstock G41 grows to 50cm, bury the new branch of dwarf rootstock G41 with fresh sawdust, and the height of burial is 20cm. In March of the next year, cut the rootstock from the horizon with pruning shears before germination in spring and harvest ...

Abstract

The invention discloses a breeding method of an apple dwarf self-rooting multi-branch nursery stock. The breeding method comprises the following steps: firstly selecting apple dwarf rootstock varieties G41, M9, Pajam1 and T337 as maternal stocks, establishing an apple dwarf rootstock breeding seedbed, and using saw dust to cover newly grown branches of the apple dwarf rootstocks on the seedbed from the beginning of June to the beginning of July, so as to breed the apple dwarf rootstocks with good root systems; planting the apple dwarf rootstocks in a density of 5000-6000 plants per mu in a nursery garden in spring, establishing the nursery garden for producing finished nursery stocks; and grafting apple variety in autumn in the same year to obtain the apple dwarf self-rooting multi-branch nursery stocks in the next year. With the adoption of the cultivation method provided by the invention, the disadvantages of poor quality of nursery stocks produced by the existing stock breeding method, thin and weak nursery stocks, and low survival rate of the nursery stocks in the established nursery garden are overcome.

Description

technical field [0001] The invention belongs to the field of apple tree seedling cultivation methods, and relates to a method for cultivating apple dwarf self-rooted multi-branched seedlings. Background technique [0002] Seedling raising methods affect the quality of apple seedlings. At present, the breeding of apple seedlings in my country mainly includes two methods, arborization seedling breeding and dwarfing intermediate stock seedling breeding, both of which are to collect the seeds of the genus Apple and then graft them. The seeding volume is large, the growth of seedlings is uneven, and the quality is generally not high. . Li Gaochao of Northwest A&F University (Journal of Northwest A&F University: Natural Science Edition, No. 8, 2011) conducted a survey on nurseries around Yangling, Shaanxi. The proportions of seedlings that meet the requirements of my country's third-level standards are only 1.1% and 2.8%, and the proportions of 2-year-old arbor seedlings and 3-yea...
