Embodiment 1

[0020] Embodiment 1: North American Ilex fruit growth and development period (July 13, 55d after bearing fruit) in July, at long 20~60cm, about 0.5cm in diameter, the 10cm place girdling below the dense branch of the fruit that grows robustly, does not have damage by diseases and insect pests, With a width of 0.5cm, apply a mixed solution of 250mg / L naphthaleneacetic acid (α-NAA) and 100mg / L indolebutyric acid (IBA) root inducer on the girdling where the cambium has been removed, and then use wet peat: Perlite = 3:1 (V:V) layering matrix wraps the girdling area, forming a cylindrical shape with a length of 6-10cm and a diameter of 4-6cm, then wrapping it with polyethylene plastic film, tightening the upper and lower openings, and binding the upper part Organize and grow into a funnel shape of 3 to 4 cm, which is used to receive water and keep it moist. After 22 days, the girdling part of the branch will start to take root. After 60 days, the root system will be covered in the s...

Embodiment 2

[0021] Embodiment 2: North American holly fruit growth and development period in June (June 23, 35d after bearing fruit), be 60cm in length, about 1.5cm in diameter, girdling at 8cm below the dense branches of fruit that grow robustly and have no damage by diseases and insect pests, width 1.0cm, apply a mixed solution of 125mg / L naphthaleneacetic acid (α-NAA) and 50mg / L indolebutyric acid (IBA) root inducer on the girdling area where the cambium has been removed, and then use wet peat: pearl Rock = 1:1 (V:V) layering matrix wraps the girdling area, forming a cylindrical shape with a length of 6-10cm and a diameter of 4-6cm, then wraps it with polyethylene plastic film, and then tightens the upper and lower openings, and the upper part is tied. It grows 3 to 4 cm in a funnel shape, which is used to absorb water and keep it moist. After 25 days, the girdling part of the branch begins to take root. After 65 days, the root system is covered in the substrate. Cut the rooted branch f...

Embodiment 3

[0022] Embodiment 3: August North American holly fruit growth and development period (August 17, 90d after bearing fruit), be 50cm in length, about 1.0cm in diameter, girdling at 10cm below the dense branch of the fruit that grows vigorously, without damage by diseases and insect pests, width 0.5cm, apply a mixed solution of 500mg / L naphthaleneacetic acid (α-NAA) and 200mg / L indolebutyric acid (IBA) root-inducing agent on the girdling area where the cambium has been removed, and then use wet peat: pearl Rock = 2:1 (V:V) layering matrix wraps the girdling area, forming a cylindrical shape with a length of 6-10cm and a diameter of 4-6cm, then wraps it with polyethylene plastic film, and then tightens the upper and lower openings, and the upper part is tied. It grows 3 to 4 cm in a funnel shape, which is used to absorb water and keep it moist. After 21 days, the girdling part of the branches begins to take root. After 62 days, the root system is covered in the substrate. Afterwar...

Abstract

The invention discloses a method for cultivating North America holly dwarf products through upper air layering. The method includes the following steps that in the growth and development period of North America holly fruits, a branch which is 20-60 cm in length and about 0.3-1.5 cm in diameter, grows vigorously, is free of plant diseases and pests, and has dense fruits is selected, the 5-10 cm position of the lower portion of the branch is girdled, the girdling width is controlled to range from 0.5 cm to 1.5 cm, a cambium is completely removed, the girdled position is coated with a root inducing agent mixed solution, then the girdled position is coated with a layering medium with the water content ranging from 60% to 80%, finally, the girdled position is wrapped by a plastic film, then an opening and a lower opening are tied, and wetness is kept. 60-70 days later, the medium is full of root systems, the rooting branch is cut off from the wrapping position of the medium, part of leaves are removed, then the rooting branch is transplanted in a culture medium with the ratio of peat to perlite of 3:1(V:V), the medium and the environment are kept wet, the branch is put in shade for seedling recovering for about 20 d, and the survival rate is 96.2% or above. The method has the advantages of being easy and convenient to operate, high in maneuverability, low in cost and high in survival rate, and is an important technical means for achieving dwarfing and miniaturization of North America holly products.

Description

technical field [0001] The invention belongs to the field of plant breeding, and relates to a method for dwarfing fruit ornamental plants, in particular to a method for dwarfing high-altitude layering of North American holly (Ilex verticillata). technical background [0002] North American holly (Ilex verticillata), also known as whorling holly and American holly, is a perennial deciduous shrub of the genus Ilex (Ilexlinn.), dioecious, with a tree height of 2-3 meters. At the end, the fruit color turns red in early October, and the leaves fall in early and mid-December; the natural fruit-hanging period is until April of the following year, and the fruit is bright red and shiny. It often enters the New Year's Eve flower market in the form of cut branches, potted plants and other horticultural products. This plant is also an excellent tree species for gardens and garden beautification, and can be planted alone, in rows or in groups. In addition, because of its strong water an...
