Method for carrying out grafting and seedling cultivating on prunus cerasifera

Abstract

The invention discloses a method for carrying out grafting and seedling cultivating on prunus cerasifera. The method comprises the following steps of (1) prunus davidiana stock seedling cultivation; (2) scion preparation; (3) scion grafting; (4) post-grafting management. According to the method disclosed by the invention, prunus davidiana stock seedlings cultivated by the invention are vigorous in growth vigor, good in root development and strong in drought-resisting and cold-resisting capacity, the seedling cultivating method is simple, and the cost is lower; several different kinds of prunus cerasifera scions can be grafted on each prunus davidiana stock seedling, on one hand, the grafting survival rate of each prunus cerasifera stock seedling is up to more than 99 percent, on the other hand, a better appreciation value can be brought by one multi-variety grafting seedling after the ripening of the multi-variety grafting seedling; by adopting a grafting method of bud grafting and matching with a special healing agent, the survival rate of scions is greatly increased, the healing rate is fast, and the later-period growth vigor is vigorous. According to the method disclosed by the invention, the grafting operation of the prunus cerasifera can be completed in the year when the prunus davidiana stock seedlings are cultivated, the seedling cultivating time is shortened and is more than one year earlier than that of a common grafting and seedling cultivating method, the efficiency is increased, and the economic benefit is further increased.

Description

technical field [0001] The invention belongs to the field of planting, and in particular relates to a method for grafting and raising seedlings of red-leaf plums. Background technique [0002] Red leaf plum (Prunusceraiferac v. Pissardii), a small tree belonging to the genus Prunus in the family Rosaceae, is also known as purple leaf plum. The young leaves are bright red and the old leaves are purple. It is an excellent variety for viewing leaves and flowers. Crown round or oblate, branchlets reddish brown. Flowers are solitary or 2-3 in clusters, pink, flowering period is April-May. Like sunshine, like warm climate, not cold-resistant, relatively humidity-resistant. It has strong adaptability to soil and has certain drought resistance. The root system is shallow and the germination force is strong. Native to Southwest Asia, it is widely planted in North China and the south of my country. Grafting and breeding are commonly used in the production of Hongye plum in the pr...

Problems solved by technology

However, the survival rate is low, the color is lightened, the interface is not well healed, the growth of the plant is not good, if there is splitting, falling off, the branches are not thick, etc., and the grafting period is long and the growth is slow.
