Embodiment 1

[0032] Cuttings are collected and cuttages are collected in April, and open-air cutting beds are built in leeward, sunny places with good water permeability. The length and width of the cutting beds are 16-20 m×1 m, and the bottom of the cutting beds is coarse sand. Use peat soil, red mud and fully decomposed coco peat as the raw materials of the cutting mixed matrix, and the volume ratio is 2:2:1, mix well, then put it into an 8×12 nutrition bag, and place it tightly on the cuttings In the bed; 1 day before cutting, the substrate was disinfected with 0.1% potassium permanganate.

[0033] The collection of spikes is to use sharp scissors to cut 10-12 cm long, healthy, semi-lignified green branches as close as possible to the base of the branches on the mother tree for cutting. Cut the semi-lignified cuttings into 8-9 cm single-leaf and single-bud cuttings. The lower end is obliquely cut, the upper end is close to the bud, flat-ended, and tied with rubber bands. Then the cutti...

Embodiment 2

[0038] Cuttings are collected and cuttages are collected in July. Choose a leeward sunny place with good water permeability to build an open-air cutting bed. The length and width of the cutting bed are 10-12 m×1.2 m. The bottom of the cutting bed is coarse sand on gravel. Peat soil, red mud and fully decomposed coco peat are used as the raw materials of the cutting mixed matrix, and the volume ratio is 2:2:1. Mix well, then put it into an 8×12 nutrition bag, and place it tightly on the cuttings. In the bed; 1 day before cutting, the substrate was disinfected with 0.1% potassium permanganate.

[0039]The collection of spikes is to use sharp scissors to cut 10-12 cm long, healthy, semi-lignified green branches as close as possible to the base of the branches on the mother tree for cutting. Cut the semi-lignified cuttings into 8-9 cm single-leaf and single-bud cuttings, the lower end is oblique, the upper end is close to the bud, flat, and tied with a thin cotton rope. Then arra...

Embodiment 3

[0044] The cuttings collection and cutting time are February. Choose a leeward sunny place with good water permeability to build a nursery elevated shade shed and cutting bed. The length and width of the cutting bed are 10 m×1.2 m. The cutting bed is made of coarse sand as the bottom. Peat soil, red mud and fully decomposed coco peat are used as the raw materials of the cutting mixed matrix, and the volume ratio is 2:2:1. Mix well, then put it into an 8×12 nutrition bag, and place it tightly on the cuttings. In the bed; 1 day before cutting, the substrate was disinfected with 0.1% potassium permanganate.

[0045] The collection of spikes is to use sharp scissors to cut 13-15 cm long, healthy, semi-lignified green branches close to the base of the branches on the mother tree of the spikes as cuttings and cuttings. Cut the semi-lignified cuttings into 10 cm single-leaf and single-bud cuttings, with a slanted lower end and a flat upper end close to the bud, and tie them up with r...

Abstract

The invention relates to a method for cutting propagation by utilizing lithocarpus polystachyus epicormic branches. The method is characterized by comprising the working procedures of cutting bed preparation, cutting slips acquisition and processing, cutting and post-cutting management, cutting in a seedling raising garden by utilizing the lithocarpus polystachyus epicormic branches, and obtaining high-quality lithocarpus polystachyus nursery-grown plants through controlling illumination, relative humidity and water content of a substrate. The method utilizing the lithocarpus polystachyus epicormic branches belongs to a vegetative propagation means, and has the advantage of being capable of maintaining excellent characteristics of seed trees. Compared with sowing seedlings, the cutting seedlings are obviously increased in growth speed, large in growth amount and high in adaptability in the initial stage after being planted. The method is simple and feasible, high in efficiency, low in cost, high in propagation speed and high in propagation coefficient, the characteristics of excellent strains can be well maintained, limitation to the time and the season is avoided, the propagation efficiency and continuity are facilitated, and the method can be directly applied to actual production and has better economic benefits, social benefits and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a propagation method of polyacylaceae, in particular to a method for propagating by cuttings of twigs of polyacylaceae. Background technique [0002] Dosuke (L ithocarpus polystachyus ) is a precious tree species of forest source medicinal materials. It has been made into "sweet tea" for drinking by the folks. It has been passed down for thousands of years, especially the sweet tea produced in Bama County, Guangxi, China. It is called "longevity tea". , is favored. Flavonoids are the main medicinal components of Dosuikea, and their content exceeds 30%, especially phlorizin and trilobatin, which are dihydrochalcone glycosides, have attracted much attention. The flavonoids of Polyacae flavonoids have strong anti-oxidation and various health care functions. Especially in recent years, studies have found that Polyacaceae and its extracts have obvious effects of l...
