Embodiment 1

[0025] (1) Selection of rootstock: choose perennial Chinese cherry blossoms (Cerasus conradinae) with a diameter of breast height of 12-14cm and a main branch point of 2.8-3.0m as the rootstock, and choose 2-3 roots with a uniform distribution of angles on the rootstock and a thickness of 2-3cm. The branch is used as the interface for cutting, and the interface on the high branch is at a distance of 15-20cm from the branch point of the side branch and the main trunk;

[0026] (2) pruning of scion: cut a long inclined plane at 1cm place of the lower bud of weeping cherry scion, the length of long inclined plane is 1.5-2cm, cut a short inclined plane at the opposite side of long inclined plane, the length of short inclined plane is 0.8-1cm; Cut the weeping cherry scion into small sections with 2-4 buds and a length of 7-8cm, wrap the top of the scion with insulating adhesive tape to bind and seal; put the trimmed weeping cherry scion into the Soak in the treatment solution for 2...

Embodiment 2

[0030] The present embodiment selects grass cherry (Cerasus fruticosa Pall.) as rootstock, other steps are all the same as embodiment 1. A total of 210 scions were grafted from 78 weeping cherry trees. After 3 months of grafting, the survival situation was observed. 92 scions survived, with a survival rate of 43.8%. Each scion produced 13-18 branches in the same year.

Embodiment 3

[0032] The present embodiment selects Guanshan cherry (Cerasus serrulata var. lannesiana 'Kanzan') as rootstock, and other steps are all the same as embodiment 1. A total of 199 scions were grafted from 71 weeping cherry plants. After 3 months of grafting, the survival situation was observed. 114 scions survived, with a survival rate of 57.3%. Each scion took out 7-15 branches in the same year.

Abstract

The invention provides a top grafting and cultivation method of cerasus yedoensis using cerasus conradinae as a stock. According to the method, the cerasus conradinae which belongs to the cerasus of rosaceae like the cerasus yedoensis is adopted as the stock, so that the method has the advantages that the affinity is high, wound healing is fast, and scions grow fast; the scions are soaked in treating fluid, and the steps and parameters of top multiple-head grafting are optimized, so that the reproduction speed of the cerasus yedoensis is increased; through each scion top grafted in spring, 20-30 branches can be sprouted in the same year, the longest growing length of each branch during defoliation in autumn and winter can reach 1.5 m, each bud can sprout 20-30 branches in the first half of the next year, and wounds heal properly in the third year; a crown is full, and top grafted seedlings can come out a nursery for being used in an engineering project.

Description

technical field [0001] The invention belongs to the technical field of garden plant breeding, and specifically relates to a method for cultivating weeping cherry blossoms by high-level grafting using cherry blossoms as rootstocks. Background technique [0002] Cherry blossom is the collective name of several plants of the genus Cerasus in the family Rosaceae. In the newly revised name of "Flora of China", it refers specifically to "Tokyo cherry blossom", also known as "Japanese cherry blossom" and "Edo cherry blossom". According to the "Sakura Dakan" written by Japanese scholars, the earliest origin of cherry blossoms was China, where they grew in the Himalayas and were introduced to Japan later. As early as the Qin and Han Dynasties, cherry blossom cultivation had been used in palace gardens, with a history of more than 2,000 years. Cherry blossoms have been cultivated in Japan for more than 1,000 years. There are many varieties, including hundreds of artificial hybrids an...
