Embodiment 1

[0036] A method for grafting crowns of Jingxi Daguo hawthorn trees, the main steps are as follows:

[0037] (1) Spike collection

[0038] Select the Jingxi Daguo Hawthorn, which grows robustly and grows well, as the mother tree for picking ears, and collect robust growth, no pests and diseases, full bud eyes, and 1-year-old branches with a diameter of 0.6-1.0cm on the mother tree for picking ears in November-December. The branches that have been picked are removed from the leaves and sealed with a film and placed in a cool place indoors for preservation as a scion for subsequent use;

[0039] (2) Grafting time

[0040] Choose to graft from late November to early and mid-January, that is, before the Jingxi Daguo Hawthorn blooms, it starts to germinate, and grafts before new leaves emerge; choose sunny or cloudy days for grafting, and rainy days are not suitable for grafting;

Abstract

The invention discloses a grafting method for crown replacing of a Jingxi fructus crataegi pinnatifidae big tree. The method includes the steps of scion collecting, grafting time setting, grafting crown replacing and after-grafting management. The Jingxi fructus crataegi pinnatifidae tree robust in growth and good in growth vigor is selected as a scion collecting seed tree, one-year-old branches robust in growth are collected as scions, 5-10-year-old big trees vigorous in growth are selected from a Jingxi fructus crataegi pinnatifidae tree natural forest, grafting crown replacing is conductedfrom the last ten days of November to the first and middle ten days of January, and the Jingxi fructus crataegi pinnatifidae excellent species big tree is obtained through shade removing, unbinding and plant disease and insect pest preventing and treating after grafting. Strong root systems and robust branches and trunks of an existing Jingxi fructus crataegi pinnatifidae big tree are sufficientlyused, multi-head grafting is implemented, the forest form is neat, the excellent species is kept, the new rich-yield tree crown can be formed two years after grafting, the yield and quality of the Jingxi fructus crataegi pinnatifidae tree can be improved within a short period of time, and good economic benefits, social benefits and ecological benefits are realized.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a grafting method for changing the crown of a Jingxi big fruit hawthorn tree. Background technique [0002] Jingxi Daguo Hawthorn (Crataegus jingxiensis Li) is a new variety discovered in Jingxi by the National Hawthorn Census Cooperation Group in the early 1980s. In 1985, it was officially designated as Jingxi Daguo Hawthorn by forestry expert Li Xiangdong and others. Jingxi Daguo Hawthorn is distributed in Jingxi, Debao, Napo, Tian'e in Guangxi, Funing, Xichou and other counties in Yunnan, and Jingxi is the most widely distributed. The earliest record of Jingxi Daguo Hawthorn can be found in the "Records of Guishun Prefecture" compiled in 1889 (Guishun Prefecture is now Jingxi County). At that time, there were records of the shape, taste, production and sales of the fruit. In the mid-1950s, the highest annual output reached 1,500 tons. By the beginning of th...
