Embodiment 1

[0021] A high-efficiency cutting propagation method for Osmanthus osmanthus, the specific steps comprising:

[0022] 1. Construction of cutting bed

[0023] Choose mild clay and fertile nursery land to make slotting beds, and fully plow the nursery land with a depth of not less than 30cm. The specifications of the slotting bed are: bed width 1.2m, bed height 30cm, walkway width 30cm, and the length depends on the length of the nursery. Directly use the fine loam soil in the nursery as the cutting substrate, and use 500 times of 50% carbendazim soluble powder for spraying and stirring disinfection 7 days before cutting.

[0024] 2. Collect branches and prepare spikes

[0025] At the beginning of July, choose the semi-lignified branches of the 3-year-old seedlings as cuttings. 3 days before collecting the branches, the ear-picking mother tree was fully watered. The branches are collected in the morning, and the spikes are quickly prepared in the shade. The length of the cut...

Abstract

The invention provides a high-efficient cutting propagation method of osmanthus serrulatus. The method strictly controls a source of osmanthus serrulatus twig cuttings, the cuttage time, preparation of cuttings, a cuttage process, the composition, concentration and treatment time of rooting inducing hormones, as well as the cuttage environment conditions, and is realized through the steps of selection of cuttings, selection of the cuttage time, preparation of the cuttings, hormone treatment, cuttage and cuttage post-management, etc. Because of strengthening the control of key links of the source of the osmanthus serrulatus twig cuttings, preparation of the cuttings, the cuttage environment conditions, etc., the cuttings can be rooted quickly, the roots of the cuttings can be increased quickly, the root quality of the cuttings is improved, the cuttage rooting rate of the twig cuttings reaches 80% or above, the seedling success rate of the rooted cuttings reaches 85% or above, and a goodtechnical foundation is laid for realizing industrial development of the cultivation of osmanthus serrulatus seedlings.

Description

technical field [0001] The invention relates to the field of propagation of forest tree seedlings, in particular to a method for efficient cutting propagation of Osmanthus fragrans. Background technique [0002] Osmanthus serrulatus Rehd. belongs to the genus Osmanthus of Osmanthaceae. It is a unique tree species in my country. The type specimen is produced in Baoxing County, Sichuan Province, so it is also called Baoxing Osmanthus fragrans. Osmanthus short silken was first discovered in Ebian, Sichuan in the early 20th century. The American botanist A. Rehder identified the species as a new species and published it in the book "Plantae Wilsonianae" in 1916. "Flora of China" once recorded that this species is distributed in Sichuan, Guangxi, and Fujian. It has been proved that the distribution of wild populations of this tree species is very narrow, only in Xiling Snow Mountain, Emei Mountain, Dongla Mountain, Hanyuan and Jinkou River in Sichuan. It is scattered in mountain...
