Cutting propagation method for osmanthus trees

Abstract

The invention discloses a cutting propagation method for osmanthus trees, and relates to the technical field of seedling planting of osmanthus trees. The method is characterized by comprising the following steps: cutting selection: collecting cuttings in April, and trimming into cuttings of 18-22 centimeters; root forcing treatment: digging a pit of which the depth is 3-4 meters, blending and disinfecting river sand by using 25 percent carbendazim wettable powder, paving fine sand on the bottom surface of the pit by 15 centimeters in thickness, leveling, soaking the cuttings with a 0.1-0.3 percent potassium permanganate solution for 15 minutes, vertically and reversely placing the cuttings onto the fine sand at close intervals, covering with fine sand by 5-10 centimeters in thickness for filling gaps after one layer of cuttings is placed, placing a second layer, continuously placing 3-4 layers, and spraying water once every day to keep the fine sand wet; land preparation and cuttage: selecting a cuttage seedbed, ridging and performing cuttage in last May; post-cuttage management. The cutting propagation method has the advantages of high rooting speed, high rooting rate, high survival rate, large sizes of cuttings, quick outplanting and contribution to increase of the economical benefit.

Description

technical field [0001] The invention relates to the technical field of osmanthus tree seedling cultivation and planting, and relates to a cutting propagation method of osmanthus tree. Background technique [0002] Sweet-scented osmanthus tree, evergreen broad-leaved tree. Young roots light yellowish brown, old roots yellowish brown. The leaves are opposite, the leaf surface is smooth, leathery, the adaxial surface is dark and bright green, the abaxial surface is lighter, and there are 2 to 3 pairs of overlapping buds. Osmanthus fragrans likes to grow in warm areas. It has strong stress resistance, high temperature resistance, and is not afraid of cold. Therefore, it can survive the winter in the open field in the areas south of the Qinling Mountains and Huaihe River in China. The propagation methods of sweet-scented osmanthus include sowing, cutting, grafting and layering. Propagation by cuttings and grafting is the most common in production. The growth of osmanthus is v...

Problems solved by technology

The growth of sweet-scented osmanthus is very slow, and the survival rate of cuttings is not high, mainly because the cuttings of sweet-scented osmanthus trees are difficult to root when cutting, and the cuttings of existing sweet-scented osmanthus trees are relatively small, and the speed of coming out of the nursery is slow.
