Cutting seedling method of osmanthus fragrans

Abstract

The invention discloses a cutting seedling method of osmanthus fragrans. The method comprises operation steps as follows: (1) an excellent plant which grows vigorously and is not damaged by diseases or insects is taken as a mother tree for cutting, and one-year-old half-lignified twigs at the upper part of the periphery of a tree crown of the excellent plant are sheared to serve as cuttings; (2) the base parts of the cuttings are cut into planes and uniformly coated with a yellow gelatin nutritional solution; (3) the cuttings coated with the yellow gelatin nutritional solution are put in a greenhouse at the temperature of 23-27 DEG C and irritated by purple light, and the cuttings are taken out after 4-5 days; (4) the nutritional solution at the base parts of the cuttings are washed clean and a rooting liquid is uniformly sprayed to the base parts of the cuttings; (5) the cuttings with the rooting liquid sprayed are perpendicularly inserted into a seedling bed and watered thoroughly, and other seedling bed management work is done. By means of the cutting seedling method of osmanthus fragrans, the rooting rate of the cuttings of the osmanthus fragrans and the survival rate of seedlings can be effectively increased, the rooting speed of the cuttings is increased, the cutting cycle is shortened, damage of diseases and insects to the cuttings can be reduced, and the quality of the seedlings of the osmanthus fragrans is improved.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a method for raising seedlings by cuttings of bay laurel. Background technique [0002] August laurel includes Jingui and Yingui, which are produced in the north subtropical deciduous and evergreen broad-leaved mixed forest in the Yangtze River Basin and its south, in the middle subtropical evergreen and deciduous broad-leaved forest in the southern subtropical evergreen broad-leaved forest. Golden Osmanthus fragrans is yellow to dark yellow, with a strong aroma. Silver Osmanthus fragrans is nearly white or yellowish white, and its fragrance is weaker than that of Jingui. All are weakly positive and like warm and humid climates. However, in the process of raising seedlings of August laurel, the survival rate of the cuttings is not high, and the cuttings are easily infected with diseases and insect pests during the rooting process, which leads to a great reduction...

AI Technical Summary

Problems solved by technology

However, in the process of growing seedlings of August laurel, the survival rate of the cuttings is not high, and the cuttings are easily infected with diseases and insect pests during the rooting process, which leads to a great reduction in the quality of the August laurel seedlings, which greatly limits the development of the August laurel industry.
