Propagation method for grafting Camellia tamdaoensis Hakoda et Ninh onto camellia maozi

Abstract

The invention provides a propagation method for grafting Camellia tamdaoensis Hakoda et Ninh onto camellia maozi. The propagation method comprises the steps of carrying out management cultivation of a camellia maozi nursery stock as a stock seed tree and the imported Camellia tamdaoensis Hakoda et Ninh nursery stock as a cutting seed tree, respectively, grafting the Camellia tamdaoensis Hakoda et Ninh cuttings on the camellia maozi cutting seedlings, and controlling the light, the relative humidity and the matrix moisture content in the nursery, thereby obtaining Camellia tamdaoensis Hakoda et Ninh grafted seedlings. The propagation method is characterized in that based on the excellent stock seedling application characteristics of the camellia maozi such as many branches, high germination power, thick and easily strippable bark, and high adaptability to natural environments of drought, flooding, acids, bases, salt and high temperatures, the Camellia tamdaoensis Hakoda et Ninh which is beautiful in leaf shape, flower and crown shape and high in ornamental value and garden development value is grafted on the camellia maozi, the grafting survival rate can be more than 98%, propagation can be expanded rapidly, the propagation coefficient is high, a large quantity of Camellia tamdaoensis Hakoda et Ninh seedlings can be obtained, and after about 5-6 months of management and protection, the grafted seedlings grow as high as 50-60cm.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a propagation method of grafting Camellia camellia to Tam Island golden camellia. Background technique [0002] Camellia tamdaoensis Hakoda et Ninh (Camellia tamdaoensis Hakoda et Ninh) belongs to the Theaceae (Theaceae) Camellia (Section Chrysantha Chang) plant. It is distributed in natural parks, so it is also called Sandao Golden Camellia. The flower color of Camellia japonica is yellow, which is lighter than that of ordinary camellia japonica. The flower diameter is 4-6cm. The leaf shape, flower shape and crown shape are beautiful, with high ornamental value, great garden development value, and great potential for scientific research value. . The Forestry Science Research Institute of Guangxi Zhuang Autonomous Region introduced camellia camellia from Tam Island from Vietnam. The introduction of this camellia supplemented and enriched the germplasm resourc...

Problems solved by technology

However, many years of production practice have proved that although the survival rate of Camellia camellia grafted with these traditional Camellia oleifera species is relatively high, the grafted seedlings of Camellia camellia after survival grow relatively slowly in actual production and application, and the growth cycle is long, which restricts to a certain extent The rapid development of Camellia camellia industry, so there is an urgent need to adopt a new combination of stock and ear for Camellia camellia grafting, so as to achieve the purpose of rapid propagation of camellia camellia, and then promote the scale and industrialization of camellia camellia artificial breeding seedlings
