Method for raising seedlings of camellia chrysantha plants by top grafting

Abstract

The invention provides a method for raising seedlings of camellia chrysantha plants by top grafting. By the aid of the method, study for supporting technologies for raising the seedlings of the camellia chrysantha plants by top grafting is carried out in the aspects such as scion, rootstock selection and processing, the grafting time, culture conditions and matters needing attention, and in order to achieve purposes of increasing a survival rate and cultivating excellent strains with both ornamental value and medicinal value, a plurality of key links are improved in an emphasized manner and include that (1), large tea-oil trees at tree ages of 60-80 years are selected as rootstocks; (2), scion cuts are subjected to wax sealing processing in a scion storage period; and (3), as the rootstocks are large and are high in drying degree and crowns of the rootstocks are large, an independent spatial protection measure is adopted after grafting, in other words, protective covers are manufactured according to sizes of the trees. The method has the advantages that problems of low quantity of existing wild camellia chrysantha, extremely low fruit rate, long seedling stage duration, low emergence rate and the like in the prior art are solved, the reproductive cycle of camellia chrysantha can be shortened, seedlings can be yielded from a garden in a period ranging from half a year to a year, the survival rate can reach 95% at least, and the excellent strains with both the ornamental value and the medicinal value can be cultivated within the shortest time.

Description

Technical field [0001] The invention is the field of cultivation of economic forests. It involves cutting and breeding methods of medicinal and ornamental plants, and also involves a method of grafting seedlings in high levels of golden flower tea plants. Background technique [0002] Golden Flower Tea ( Camellia chrysantha ) Department of Shan Tea ( Theaceae ) Mountain tea ( Camellia ) Jinhua Tea Group ( sect.chrysantha ) Plants, mainly distributed in Yongning County, Guangxi. Because it contains special yellow -colored gene KNA in the plant world, it is very rare in the plant world. It fills the gap of the yellow series camellia. As a rare plant resource in the world (only distributed in the border area of ​​Guangxi and Vietnam), it is one of the eight national protection plants in my country. It is difficult to find, and it is regarded as a noble treasure in the golden flower tea.According to the test results of medical authority, Jinhua Tea is a non -toxic grade, without side...

Problems solved by technology

[0004] In order to solve the existing number of wild Camellia japonica in the prior art, the fruit rate is extremely low, the seedling period is long, and the emergence rate is low. The purpose of the present invention is to provide A method for raising seedlings by high-position grafting of camellia japonica plants, which enables the survival rate to reach more than 95%, and at the same time cultivates excellent strains with both ornamental and medicinal uses in the shortest time
