Seedling culture method for promoting rooting during oriental cherry grafting

Abstract

The invention discloses a seedling culture method for promoting rooting during oriental cherry grafting. Current-year branches of grass cherry (dedicated stock for oriental cherry grafting, suspected to belong to cherry strain) are used as stock, current-year branches of good oriental cherry stock are used as scion, cut-grafting is adopted, cuttage is conducted after grafting, the stock is rooted first after cuttage, and massive secondary rooting is caused at a graft union after transplantation to form oriental cherry variety seedlings with firm interfaces. In mid-to-end of January and early-to-mid of February each year, good stock branches which grow robustly are collected for grafting, then cuttage is conducted directly in a greenhouse or field cutting is conducted directly, stock is transplanted into pots or directly planted in the ground after cutting rooting, and massive rooting and seedling culture of the graft union are induced by means of cultivation techniques. The advantages of the two breeding methods, namely grafting and cuttage, are combined and utilized, universality is high, and the method is suitable for expanding propagation of most oriental cherry varieties and wild oriental cherry germplasm resources; furthermore, massive rooting of a grafting position is achieved, the graft union is not broken easily, and thickness difference of ordinary grafted seedlings is avoided.

Description

technical field [0001] The invention belongs to the field of gardens, in particular to a seedling raising method for cherry blossom grafting to promote rooting. Background technique [0002] Sakura refers to the ornamental plants of the genus Prunus in the family Rosaceae. There are more than 120 species in the world, and more than 600 artificially cultivated varieties. Most of the cherry blossoms are deciduous trees with a large amount of flowers and a concentrated flowering period, which is very beautiful when blooming. At present, there is an upsurge of cherry blossoms in our country. There are cherry blossom theme gardens and cherry blossom roads in many areas. There is a large demand for cherry blossom seedlings. However, most of the cherry blossom varieties are grafted with rooted rootstocks such as cherries and cherries. The efficiency of seedling production is not high. Therefore, the seedlings of fine varieties of cherry blossoms are difficult to meet the market de...

At present, there is an upsurge of cherry blossoms in our country. There are cherry blossom theme gardens and cherry blossom roads in many areas. There is a large demand for cherry blossom seedlings. However, most of the cherry blossom varieties are grafted with rooted rootstocks such as cherries and cherries. The efficiency of seedling production is not high. , the seedlings of fine varieties of cherry blossoms are difficult to meet the market demand; and the grafted seedlings generally have the problems of "big and small feet" and the interface is easy to break

Prunus plants belong to the type that is difficult to root from cuttings. At present, the survival rate of cuttings of cherry varieties that have been reported is mostly difficult to meet the requirements of large-scale production and seedling cultivation.
