Method for carrying out grafting and seedling cultivating on ornamental prunus persica chrysanthemoides

Abstract

The invention discloses a method for carrying out grafting and seedling cultivating on ornamental prunus persica chrysanthemoides. The method comprises the following steps of (1) prunus davidiana stock seedling cultivation; (2) scion preparation; (3) scion treatment; (4) scion grafting; (5) 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 compatibility of the prunus davidiana stock seedlings and prunus persica chrysanthemoides is higher, strong assurance is provided for the growth of the prunus davidiana stock seedlings, the seedling cultivating method is simple, and the cost is lower; after ultrasonic treatment is carried out on sprout scions of the prunus persica chrysanthemoides, the tissue characteristics are changed, division and differentiation of cells are stimulated, growth and development of blossom buds are promoted, and variation seedlings can appear at the same time, so that the flower color has other characteristics different from red, the ornamental value is increased, and the grafting survival rate is also increased. According to the method disclosed by the invention, the grafting operation of the prunus persica chrysanthemoides 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 ornamental chrysanthemum and peach seedlings. Background technique [0002] Chrysanthemum peach (scientific name: Prunus persica Chrysanthemoides), belongs to Rosaceae, Rosaceae deciduous shrubs or small trees, chrysanthemum peach is named for its flower shape resembling chrysanthemum, is a precious species in ornamental peach blossoms, distributed in northern and central China. The chrysanthemum peach plant is small, compact in shape, luxuriant in flowering, peculiar in shape, bright in color, and high in ornamental value. It can be used for garden and street tree planting, and can also be planted in squares, lawns, courtyards or other garden places. At present, chrysanthemum peaches are mostly propagated by grafting. One to two-year-old mountain peaches, peaches or apricot seedlings are often used as rootstocks. However, most of the grafting methods are...

AI Technical Summary

Problems solved by technology

At present, chrysanthemum peaches are mostly propagated by grafting. One to two-year-old mountain peaches, peaches or apricot seedlings are often used as rootstocks. However, most of the grafting methods are relatively rough, resulting in a decline in the survival rate of grafting and the quality of seedlings.
