Propagation method for rapid spikelet breeding of ithocarpus polysachyus rehd

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...
