Apple breeding method

Abstract

The invention discloses an apple breeding method. The method comprises the steps as follows: scions are sheared into short shoots which are 5-10 cm long and have two buds; roots of the scions are cutinto smooth long slopes about 2.5 cm long by a knife from one side where no buds exist, one side (scion ends) where the buds exist is cut into flat wedges, and the scion ends are placed in a homemadesoaking solution to be soaked for 6-8 h; dwarfed self-rooted stocks or dwarfed interstocks are selected to form self-rooted nutrient stocks by laying propagation, upper ends of the stocks are shearedinto flat openings, and cuts with depth of about 2.5-3 cm are longitudinally formed downwards from branches at about 1/4 positions of cut sections; scions are inserted into stock cuts, so that the scions and the stocks are closely attached without seams, layers are aligned to each other, and 0.2 cm of upper ends of scion cutting surfaces are exposed for binding. The graft survival rate reaches 95%or above, meanwhile, apple trees grow fast after grafting, crowns take shape and bear fruits early, and the juvenile period can be shortened by 2-3 years, so that better economic benefits can be created.

Description

technical field [0001] The invention relates to the field of apple cultivation, in particular to an apple breeding method. Background technique [0002] Apple, a deciduous tree, the leaves are oval and serrated, and the flowers are white with a blush. The fruit is round and sweet or slightly sour. It is a common fruit, rich in nutrients, and has the functions of dietotherapy and auxiliary treatment. It is one of the four major fruits in the world. Apples are usually red, but also yellow and green, and are the fruit of a plant. Apples are native to Europe, Central Asia, West Asia and Turkey, and were introduced to China in the nineteenth century. China is the world's largest apple producer, and it is cultivated in Northeast China, North China, East China, Northwest China, Sichuan, and Yunnan. Apple is a common fruit and the most common fruit. It is rich in vitamin nutrition and is the crown of the world's four major fruits (apples, grapes, citrus and bananas). [0003] Kn...

Problems solved by technology

[0003] Known, grafting is undoubtedly a good way to shorten childhood, it can shorten the childhood of fruit trees to a certain extent and enter fruiting period ahead of schedule, but the problem of low success rate of grafting generally exists in existing apple tree grafting method, increases fruit grower's life. planting cost
