Grafting and seedling raising method of prunus cerasifera with high cold resistance and high adaptability

Abstract

The invention discloses a grafting and seedling raising method of prunus cerasifera with high cold resistance and high adaptability. The grafting and seedling raising method comprises the following steps: selecting sources of seeds; selecting nursery gardens; sowing seeds; performing treatment on nursery stocks of the prunus cerasifera; performing grafting; performing post-grafting management andpest and performing prevention and control of plant diseases and insect pests. According to the grafting and seedling raising method disclosed by the invention, the characteristics that the prunus cerasifera and plum trees are grafted, the grafted raising seedlings have the characteristics that the prunus cerasifera is difficult to get sick, and also have the advantage of high cold resistance of plum blossom, and moreover, findings prove that the prunus cerasifera and the variety of plum blossoms are high in affinity and high in grafting survival ratios; and meanwhile, a set of complete seedling raising method is comprehensively and systematically proposed for various aspects including culturing from rootstock to scions, grafting treatment and post-grafting management, so that the qualityof the rootstock and the scions can be ensured, and the prunus cerasifera and the plum trees are cultured in the same nursery garden, so that grafting can be conveniently carried out, and the graftingsurvival ratios and the grafting quality are further improved.

Description

technical field [0001] The invention relates to the technical field of purple-leaf plum grafting, in particular to a cold-resistant and adaptable method for grafting and raising seedlings of purple-leaf plum. Background technique [0002] Purple Leaf Prunus: Prunus genus Rosaceae is a small deciduous tree with a height of up to 8 meters. It is native to southwest Asia and is widely planted in North China and its south. Its leaves are purple all the year round. It is a famous foliage tree species. Appropriate, it can set off the background, especially the shiny purple leaves, among the green leaves, like undefeated flowers, forming a beautiful landscape in the green mountains and green waters; [0003] In order to maintain the excellent characteristics of the female parent, the buds or branches on the excellent single plant can be grafted on the rootstock with affinity. The plants grown from the scion usually have the same excellent genetic characteristics as the female paren...

Problems solved by technology

[0003] In order to maintain the excellent characteristics of the female parent, the buds or branches on the excellent single plant can be grafted on the rootstock with affinity. The plants grown from the scion usually have the same excellent genetic characteristics as the female parent, which can promote the development of excellent varieties. In the prior art, for the grafting and seedling cultivation of Prunus chinensis, mountain peaches, apricots, elm plums, etc. are mostly selected as rootstocks, but they are not cold-resistant and have poor adaptability. Graft seedling raising method to solve the problems in the prior art
