Air layering propagation method for Camellia nitidissima

Abstract

The invention discloses an air layering propagation method for Camellia nitidissima and relates to the air layering propagation technology for the Camellia nitidissima. The propagation method has the following characteristics: (1) used chemicals: IBA (indolebutyric acid), NAA (naphthylacetic acid) and a half-and-half mixed solution of IBA and NAA are taken as test chemicals; (2) the method: tests about influence of growth regulator treatment, binding substrate, girdling width and layering diameter on rooting survival rate for air layering propagation of the Camellia nitidissima are performed; (3) branch selection: a seed tree with pure variety, high and stable yield and robust tree vigor is selected; (4) air layering time: air layering can be performed at any time in a year, most preferably in May-June. The method has the advantages that the culture method is simple and easy to operate and is applied to actual seedling production more easily and effectively, and the rooting effect is better. The invention aims to provide the air layering propagation technology which is more applicable to actual production in a non-place-of-origin environment and is more effective for the Camellia nitidissima.

Description

technical field [0001] The invention relates to the propagation technique of Camellia japonica ring branches. Background technique [0002] Camellia nitidissima (Camellia nitidissima) was first discovered in Guangxi, my country in the early 1960s. It is an evergreen shrub to small tree belonging to the Camellia family Camellia subgenus Camellia. The petals are waxy golden yellow. The only parent available. The "Chinese Plant Red Book" issued by our country in 1984 listed it as a first-class rare and endangered plant. In 1992, it was listed as a national precious tree species by the Ministry of Forestry. Listed as a national first-class protected wild plant, it enjoys the reputation of "Queen of the Tea Clan" and is also known as "The Giant Panda in the Plant Kingdom". It is an extremely important germplasm resource that can be developed. Golden camellia not only has high ornamental value and scientific research value, but also has extremely high health care value. Since 198...

Problems solved by technology

There are also some reports on the high-altitude layering propagation technology of Camellia japonica, but they are all high-altitude layering experiments in the original area of ​​Camellia chrysalis, and there are no technical reports on ring branch propagation in other areas except the origi
