Camellia-oleifera low-production-forest variety renewing grafting method

Abstract

The invention discloses a camellia-oleifera low-production-forest variety renewing grafting method. By means of the camellia-oleifera low-production-forest variety renewing grafting method, the grafting survival rate can be increased, tree vigor recovering is quickened, and the problem that if stock notches are subjected to water loss dieback, the service life of the portions above grafting openings after grafting is survived is short is solved. Inventors permit camellia-oleifera large-tree high-grafting seed-changing grafting tests in 2010, and the technical scheme of the camellia-oleifera low-production-forest variety renewing grafting method is obtained through 6-year exploration. According to the scheme, material taking is easy, operating is easy to carry out, the survival rate is high (90% or above), the grafting period is long, non-living grafting is additionally grafted in the current year, the stock notches are high in healing, and the camellia-oleifera low-production-forest variety renewing grafting method is suitable for a grafting creative application method for large-scale variety renewing transforming. The technical support is provided for camellia-oleifera low-production-forest variety renewing grafting.

Description

technical field [0001] The invention relates to an agricultural planting method, in particular to a method for renewing and grafting camellia oleifera low-yield forest varieties. Background technique [0002] Camellia oleifera (Camellia oleifera Abel) is an evergreen shrub or small tree of the genus Theaceae. It is a unique woody oil tree species in my country. It is also known as the world's four largest woody edible oil plants together with oil palm, olive and coconut. The content of unsaturated fatty acids in camellia oil is as high as 90%, mainly oleic acid and linoleic acid, and it is resistant to storage; long-term consumption can lower serum cholesterol, prevent and treat cardiovascular and cerebrovascular diseases, and is a high-quality product that is deeply loved by consumers. cooking oil. Camellia oil can also be processed into raw material oil and matrix oil of cosmetics to produce high-grade health care natural skin care products. Tea cakes can be used to extr...

Problems solved by technology

[0003] Guizhou is one of the key provinces for the development of camellia oleifera in the southwestern mountainous area. In the whole province, the area of ​​fine varieties is less than 10%, and the low-yield forest reaches more than 1 million mu. Replacement, resulting in mixed varieties, poor quality, low oil production, and poor production efficiency. The primary task of transformation is to update varieties

Camellia oleifera has hard wood and thin skin, and scion without leaves cannot survive grafting. Grafted seedlings are generally grafted with bud stock. The survival rate of grafting is low when the tree is replaced by a large tree, and the recovery of tree vigor is slow. Rotten and dry back, resulting in the death of the scion
