Embodiment 1

[0044] The 12-year-old star anise fine clones grafted and dwarfed mother trees artificially cultivated in the nursery are managed and cultivated. Firstly, the tops of the star anise mother trees are truncated and dwarfed in mid-December, and the height is kept within 2m, and the tops of each main branch are removed with branch scissors. The advantage is to promote germination, and at the same time combine pruning to remove diseased and weak branches. Remove the weeds from the crown drip line of the star anise mother tree to the root range and then loosen the soil. The depth of loose soil is 18cm. In July, the ditch fertilization method is used to fertilize once. Specifically, the crown drip line is opened wide and deep by 20cm, For an arc-shaped ditch with a length of about 100 cm, apply 0.6 kg of compound fertilizer containing nitrogen, phosphorus, potassium and trace elements to each plant, apply the fertilizer evenly into the ditch, backfill the surface soil and step on it, ...

Embodiment 2

[0047] The 11-year-old star anise fine clones grafted and dwarfed mother trees artificially cultivated in the nursery were managed and cultivated. First, the tops of the star anise mother trees were truncated and dwarfed in early January, and the height was kept within 2m, and the tops of each main branch were removed with branch pruning. The advantage is to promote germination, and at the same time combine pruning to remove diseased and weak branches. Remove the weeds from the crown drip line of the star anise mother tree to the root range and then loosen the soil. The depth of loose soil is 15cm. In August, the ditch fertilization method is used to fertilize once. Specifically, the crown drip line is opened wide and deep by 20cm, For an arc-shaped ditch with a length of about 100 cm, apply 0.5 kg of compound fertilizer containing nitrogen, phosphorus, potassium and trace elements to each plant, apply the fertilizer evenly into the ditch, backfill the surface soil and step on ...

Embodiment 3

[0050] The 14-year-old star anise fine clones grafted and dwarfed mother trees artificially cultivated in the nursery were managed and cultivated. First, the tops of the star anise mother trees were truncated and dwarfed in late December, and the height was kept within 2m, and the tops of each main branch were removed with branch scissors. The advantage is to promote germination, and at the same time combine pruning to remove diseased and weak branches. Remove the weeds from the crown drip line of the star anise mother tree to the root range and then loosen the soil. The depth of loose soil is 20cm. In February, fertilization is carried out once with the ditch fertilization method. Specifically, the crown drip line is opened at the crown drip line. For an arc-shaped ditch with a length of 100 cm, apply 1 kg of compound fertilizer containing nitrogen, phosphorus, potassium and trace elements to each plant, apply the fertilizer evenly into the ditch, backfill the surface soil and...

Abstract

The invention discloses a short-scion cutting propagation method for star anise. The short-scion cutting propagation method comprises the processes of seed tree management and culture, collection and processing of scions for cutting, cutting and management after cutting. The method comprises managing and culturing 11-year to 14-year excellent clonal grafting dwarf star anise seed trees artificially cultured in a nursery, collecting and pruning scions of 4cm to 6cm, performing cutting of the scions in a cutting bed with a cutting medium, and obtaining star anise cutting seedlings by controlling illumination in the cutting bed, relative humidity and water content of the medium. The scions obtained by the propagation method are excellent and pure in quality, take root easily, are low in cost and simple to operate, propagate rapidly, are high in propagation coefficient, and maintain characteristics of excellent clonal star anise varieties. The cutting seedlings are resistant to drought, waterlogging, wind and pest and disease damage and high in low-temperature resistance and fruit early, a tree crown is dwarf, fruit harvest is facilitated, and the cutting seedlings has good economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a method for propagating cuttages of star anise short spikes. Background technique [0002] Star anise (Illicium verum Hook. f.), also known as star anise, is native to subtropical regions such as Southwest my country and Vietnam. It is a subtropical evergreen tree and is one of the precious economic forest tree species with a long history in southern my country. It is named for its gear-shaped fruit, and each pod is composed of 7 to 9 pods, most of which are 8. The peel, seeds, and leaves of star anise contain aromatic oil, commonly known as fennel oil, which is an important spice in the food industry and daily cosmetics industry; its crown is tower-shaped, its branches and leaves are dense, and red flowers are dotted, which is very beautiful and is an excellent greening tree species ; Its wood is delicate, beautiful in color and fragrant, and it is also a go...
