Embodiment Construction

[0022] The present invention will be further described below in conjunction with an embodiment.

[0023] (1) Seedbed preparation

[0024] A semi-underground solar greenhouse was built somewhere in Pingchuan, Hanzhong City. The greenhouse is east-west, 9 meters long, 4 meters wide, and 0.9 meters deep. The wall is about 2.1 meters high, and the other three sides and the top are surrounded by plastic film. Three rows of seedbeds are arranged side by side in the east-west direction in the greenhouse. The surroundings of the seedbeds are made of bricks, and the seedbeds are separated by 0.5 meters as sidewalks. The bottom of the seedbeds is laid with 0.2 meters thick coarse sand, and the upper part is laid with 0.3 meters thick fine sand. There are micro-sprinkler irrigation facilities and drainage facilities in the greenhouse.

[0025] (2) Preparation of cuttings

[0026] Prune the sweet-scented osmanthus tree from the winter solstice to the new year's day, select annual osman...

Abstract

The invention discloses a winter long shoot cuttage propagation method for Osmanthus Fragrans, which is suitable for low-altitude areas at northern latitude of 24-33 degrees of China. The method comprises the following steps of: building a semi-underground sunlight greenhouse in any place in the areas, arranging a seedling bed in the sunlight greenhouse, cutting a branch of annual Osmanthus Fragrans, which is pruned in winter, into long shoots with the length of about 30 centimeters, processing the long shoots by using a mixed solution of a rooting reagent and a bactericide, performing cuttage of the long shoots on the seedling bed in a row spacing of 5cm and a line spacing of 10cm, ensuring the cuttage depth is 8 centimeters, covering plant stalks with the thickness of 20 centimeters among lines, and transplanting the seedlings into a field on October 1st of the same year through regular spraying of a rooting promoting liquid, plant disease and insect pest control and management, temperature control, moisture preservation and autumn seedling hardening. The method has the obvious advantages of temperature and moisture preservation, synchronous fertilizer release, and effective control over diseases, pests and grass growth, the survival rate of the cut long shoots is over 80 percent, and the average height of the seedlings in the same year is about 40 centimeters.

Description

technical field [0001] The invention belongs to the field of plant breeding, and relates to a method for asexual propagation of osmanthus trees, in particular to a method for hard branch cutting propagation of osmanthus trees. Background technique [0002] Osmanthus fragrans, belonging to Oleaceae, Osmanthus genus, is a special ornamental flower and aromatic tree in my country. Osmanthus fragrans likes a warm and humid climate, and is resistant to high temperatures but not very cold. It is a subtropical tree species. The concentrated distribution and cultivation of osmanthus in my country is the vast tropical and northern subtropical areas from the north of Lingnan to the Qinling Mountains and the south of Huaihe River, roughly equivalent to 24 degrees north latitude. °~33°. Cutting breeding of sweet-scented osmanthus trees is mostly carried out from April to September. It is a young branch cutting. The cuttings are short branches with a length of 8 to 10 cm. The depth of cu...
