A method for propagating self-root stock seedlings of apple arborization clone Begonia rotundum

Abstract

The invention relates to a method for propagating vigorous clonal Malus prunifolia own-rooted stock seedlings of apple trees. According to the method, Malus prunifolia cutting seedlings are propagated first based on the Malus prunifolia hard wood cutting technology, and the cutting seedlings are kept at the origin position to serve as stock plants; a Malus prunifolia own-rooted stock seedling layering propagation garden is built according to the vertical layering method, and the Malus prunifolia own-rooted stock seedlings are propagated in batches every year afterwards; after the Malus prunifolia own-rooted stock seedling vertical-layering propagation garden is built, the clonal Malus prunifolia own-rooted stock seedlings can be continuously harvested in 15-20 years. By means of the method, the operation of carrying out Malus prunifolia hard wood cutting propagation by crop rotation and land search every year is not needed, and more than 1 / 3 of nursery land is saved for propagating dwarf interstock apple seedlings.

[0001] The invention relates to a method for propagating self-root stock seedlings of apple arborization clone Begonia rotundum, belonging to the field of agriculture. Background technique

[0002] Round leaf crabapple is a semi-arborizing apple rootstock native to China and also distributed in Japan. Because its cuttings are easy to survive, it was widely used in apple production in Japan in the 1990s. The cultivation practice of more than 50 years has proved that the dwarf middle stock apple seedlings cultivated by using the rootstock seedlings of the round-leaf crabapple clone as the base stock has the advantages of It has the characteristics of strong growth, good resistance, high yield, uniform fruit size and excellent quality, especially for the hard-to-flower variety Red Fuji. Round-leaved crabapple has a well-developed root system, many fibrous roots, and no obvious tap root; hard branch cuttings can be used for propagation; it can resist low tempera...
