Sleeve grafting method for plants

Abstract

The invention provides a sleeve grafting method for plants, which uses sleeves to clamp the jointed parts of stock and scions after the scions are inserted into the stock. The grafting method is simple, and is easy to operate, the cost is lower, moreover, the sleeves can automatically come off after the scions grow up, the growth of plants cannot be affected, popularization and mass production are easy, the average grafting survival rate of different varieties is more than 95 percent in the ground raising method and the container raising method, and the benefit and speed of improved oil-tea camellia variety breeding can be greatly increased.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a plant grafting method, in particular to a grafting method using a casing. Background technique [0002] The production of camellia oleifera in my country has been "deep-rooted" for a long time by sexual reproduction (seed propagation), which is the main reason for the mixed varieties of camellia oleifera, mixed good and bad, inconvenient management and low yield. However, with the in-depth development of improved breeding research and the continuous generation of excellent clones, as well as the coordinated research of the majority of scientific and technological workers, the technical difficulties of Camellia oleifera vegetative reproduction have been gradually solved and have been popularized and applied in Camellia oleifera production, which has led to the improvement of Camellia oleifera production. opened the way. Among them, cutting, grafting and tissue culture are the...

AI Technical Summary

Problems solved by technology

At present, the Camellia oleifera grafting and propagation method mainly adopted in my country is the "Camellia oleifera bud seedling grafting" method successfully researched by the Subtropical Forestry Research Institute of the Chinese Academy of Forestry in the 1970s. This method greatly improves the grafting survival rate of Camellia oleifera and However, in the long-term production practice, some factors restrict the popularization and promotion of grafted seedlings and the vigorous development and application of grafted seedlings of Camellia oleifera: 1. Use aluminum foil for binding grafting, due to factors such as the proficiency of grafting workers The degree of tightness of the grafting interface is inconsistent, resulting in a large number of spikes falling off during the planting process, resulting in a large waste; at the same time, the tightness of the grafting interface affects the speed and degree of wound healing, reducing the survival rate of grafting

2. Aluminum foil is heavy, difficult to transport, and difficult to purchase. The aluminum foil produced in large quantities after grafting is poor in reuse and discarded in large quantities, causing certain pollution to the environment.

3. In some areas, plastic film is used to bind the grafting interface. Although the cost is low, it is necessary to use a blade to cut the film when the grafted seedlings emerge from the nursery, which increases labor costs and has certain requirements for grafting technology.
