Method for grafting camellia oleifera by adhering

Abstract

The invention discloses a method for grafting camellia oleifera by adhering, mainly comprising the following steps: taking out the young rootstock of the camellia oleifera which is bred in a sand bed; removing the sand, and covering a piece of wet cloth for further use; cutting off the stem which is 4.0-5.0 cm apart from the upper side of the seed, cutting off the root at the part which is 5-6 cm apart form the lower side or cutting off radicle near by the root of the seed, cutting off the root on the part which is 6-8 cm apart from the lower side, and splitting the medulla on the centre of the upper end of the stem rootstock through blades, wherein the length of the opening is 1.0-1.5 cm; adopting the semi-woodened branches of the camellia oleifera as scion, cutting the scion as a wedged shape of which the taper degree is 30 degrees, coating the adhesive at the two sides of the wedged shape of the scion, inserting the scion in the slits of the rootstock, and kneading the combination part of the rootstock and the scion until not to loosen; after grafting, pulling covers to moisture, wherein the humidity in the cover is over 80%; germinating, managing rich water and preventing damages by diseases and insects in time. The invention has the following advantages: the grafting method is simple, the operation is easily, the cost is low, the growth of the plants cannot be influenced, the popularization and mass production are easy, and the efficiency and the speed of breeding the camellia oleifera seed are greatly improved.

Description

technical field [0001] The invention relates to the technical field of agriculture, and mainly relates to a camellia oleifera glue grafting method. Background technique [0002] The production of camellia oleifera in my country has long adopted the method of sexual reproduction (seed propagation) which can be described as "deep-rooted", which is the main reason for 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 m...

Problems solved by technology

At present, the Camellia oleifera grafting and propagation method mainly adopted in China 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 Impact, 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 greater waste. At the same time, the degree of 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 protect the grafting interface. Bundling, although the cost is low, but when the grafted seedlings come out of the nursery, a blade needs to be used to cut the film, which increases the labor cost and has certain requirements for the grafting technology
