[0015] Selection and processing of cuttings:

[0016] The cuttings are taken from the seedlings, the seedlings are 7 and 10 years old, and the annual hard branches are cut in spring. The average spike length is 16.0cm, and the average spike diameter is 4.0mm. After the spikes are cut from the mother plant, the base is quickly cut into a wedge shape with a sharp knife, and every 20 pieces are bundled into a bundle.

[0017] Selection of substrate and making of mesh bag container:

[0018] The cutting substrate is peat and perlite, which are put into a blender at a ratio of 1:1 and stirred evenly, and then poured into a filling machine to be processed into a 2m long substrate sausage. Before cutting, the matrix is ​​first soaked and disinfected with 0.5% potassium permanganate solution, and then cut into short sections with a length of 14-15 cm with a fully automatic cutting machine, placed in a 58×23 cm tray and placed on a slotting bed.

Abstract

The invention discloses a method of hardwood cutting propagation of Qilian Juniper, which is characterized in that, annual hardwood of the Qilian Juniper having the age ranges from seven years to ten years is cut as branches; the average length of the branches ranges from 14.0cm to 18.0cm; the average diameter of the branches ranges from 3.0mm to 5.0mm; on the last ten days of April of each year, the branches are inserted into a greenhouse for seedling; the cutting medium is the mixture of peat and perlite mixed according to the proportion of 1:1; the cutting medium is firstly formed into a medium sausage having the length ranging from 13cm to 16cm; then the cutting medium is put in a 58 x 32cm tray and is put on the cutting bed in the greenhouse. The breeding of Qilian Juniper is realized by the method of hardwood cutting propagation. The method has the advantages of reduced seedling period of Qilian Juniper, saved cost and remarkable effect.

Description

technical field [0001] The invention relates to a plant seedling raising technology, in particular to a method for raising seedlings of Qilian juniper hardwood cuttage. Background technique [0002] Qilian juniper (Sabina przewalskii Kom.) is distributed in the northwest-southeast direction of the Qilian Mountains and extends to the Minjiang Mountains. It is one of the building species of evergreen coniferous forests in the cold temperate zone. , distributed parallel to Qinghai spruce, and is the basic community species on the sunny slope. Its tree posture is tall and straight, evergreen in all seasons, and has high ornamental value. [0003] The propagation of existing Qilian juniper has the following disadvantages: [0004] The seeds are physiologically post-ripening, and no seedlings will appear in the year of sowing, and the seedlings will not emerge neatly in the second year, which will affect production. Contents of the invention [0005] The purpose of the invent...
