Problems solved by technology

[0004] At present, Keduo multispike is mainly propagated by seeds, but the seed propagation needs to go through the process of storage and germination for more than 4 to 5 months, and the germination of the seeds is not uniform, and the offspring propagated by seeds are highly differentiated, and it is difficult to maintain the excellent traits of the female parent.
At present, the

Example Embodiment

[0031] Example 1:

[0032] In July 2011, a gentle slope land with convenient transportation, good irrigation and drainage, deep soil and fertile soil was selected as the nursery in the experimental field of Guangxi Academy of Forestry. Fully reclamation, two plows and two rakes, picking up grass roots, and driving the border. The border is 25 cm high, the border is 100 cm wide, the length is 10 m, and the trail width is 35 cm. Choose a good single plant with a height of 25 cm and a ground diameter of more than 0.3 cm without diseases and insect pests as the mother seedlings. The ridges are dug on the border surface of the picking nursery at a row spacing of 50 cm×50 cm. The ridge size and depth are 30 cm×40 cm×30 cm; apply 0.25 kg of base fertilizer per ridge, mix it with 1 / 2 of the topsoil and then return to the soil to plant the mother seedlings. The base fertilizer used is made by uniformly mixing composted tung bran and calcium, magnesium, and phosphorus.

[0036] Example 2:

[0037] In July 2012, in the experimental field of Guangxi Academy of Forestry, a flat land with convenient transportation, good irrigation and drainage, deep soil layer, loose and fertile land was selected as the ear picking nursery. Fully reclamation, two plows and two rakes, pick up the grass roots, and drive the borders. The borders are 25 cm high, 100 cm wide, 15 m long, and 35 cm wide. A good single plant with a height of 30 cm and a ground diameter of more than 0.3 cm without pests and diseases was selected as the mother seedling. The ridge was dug on the border surface of the picking nursery at a row spacing of 50 cm×50 cm. The ridge size and depth are as follows: 30 cm×40 cm×30 cm; apply 0.40 kg of basal fertilizer per ridge, mix it with 1 / 2 of the topsoil and then return to the soil to plant the mother seedlings. The base fertilizer used is made by uniformly mixing composted tung bran and calcium, magnesium, and phosphorus.

[0041] Example 3:

[0042] In June 2013, a gentle slope land with convenient transportation, good irrigation and drainage, deep soil layer, loose and fertile was selected as the ear picking nursery in the experimental site of Guangxi Academy of Forestry. Fully reclamation, two plows and two rakes, pick up the grass roots, and drive the borders. The borders are 25 cm high, 100 cm wide, 15 m long, and 35 cm wide. A good single plant with a height of 35 cm and a ground diameter of more than 0.3 cm without pests and diseases was selected as the mother seedling. The sill was dug at a row spacing of 50 cm×50 cm on the border surface of the picking nursery. The sill size and depth are 30 cm×40 cm×30 cm; apply 0.50 kg of base fertilizer per ridge, mix it with 1 / 3 of the replayed topsoil, and plant the mother seedlings in the soil. The base fertilizer used is made by uniformly mixing composted tung bran and calcium, magnesium, and phosphorus.

Abstract

The invention discloses a propagation method for rapid spikelet breeding of ithocarpus polysachyus rehd. The method comprises nursery land selection and soil preparation, building of cutting orchard, management of cutting orchard, scion wood cultivation, cutting slips collection and treatment, cuttage and after-cuttage management procedure; a single high-quality nursery stock is selected, and a ridge is excavated on a seedling trench of the nursery land, and applied with organic fertilizer as the base fertilizer, and then the stock plant is planted and cultivated as the cutting orchard; a half-lignified branch after topdressing and reasonably clipping and cultivating is used as the scion wood, and the scion wood is spliced in a nutrition cup filled with matrix; a film and a blackout screen are covered to cultivate nursery stock; thus massive high-quality ithocarpus polysachyus rehd cutting seedlings are obtained. The high-quality female parent scion wood is cultivated by the cutting orchard, the propagation amount of the scion wood is big, and the propagation speed is quick; the excellent character of the female parent is kept; the scion wood is applied to cutting propagation, so as to cultivate high-quality ithocarpus polysachyus rehd seedlings; the propagation method is short in seedling time, quick in speed, high in survival rate, simple in method, and easy to operate; the propagation method has good economical benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a propagation method of polytacia, in particular to a propagation method of rapid fringe growth of polytacia. Background technique [0002] Tachiko ( Lithocarpus polystachyus ), also known as multi-sui, sweet tea, evergreen tree or small tree, 7~15m high, is a tropical and subtropical tree species, distributed in the provinces south of the Yangtze River, and also in India and Thailand. Polygonaceae is a precious medicinal tree species. The medicinal components of Polygonaceae are mainly flavonoids, whose content is greater than 30%, among which dihydrochalcone glycosides phlorizin and trilobatin are the focus of attention . The flavonoids of Polyacae flavonoids have strong anti-oxidation and various health care functions. In recent years, studies have found that Polyacaceae and its extracts have obvious effects of lowering blood sugar and blood lipids. The s...
