Embodiment 1

[0017] Embodiment 1: (a kind of method 1 that improves the reproduction coefficient of Radix glabrata)

[0018] (1) Preparation of the mother plant body: choose the bright-leaf calyx calyx seedlings with robust growth, 6 leaves, and a crown diameter of 30 cm as the mother plant, and set aside;

[0019] (2) The type and concentration of the plant growth regulator: 15% paclobutrazol is used as the plant growth regulator, and a 50ppm medicinal solution is prepared with purified water for use;

[0020] (3) Application of plant growth regulator: Spray the plant growth regulator solution in step (2) evenly on the leaves at a rate of 20ml / per plant;

[0021] (4) Branching and transplanting: After the side buds germinate in the leaf axils at the base of the mother plant, the side buds that grow to more than 10cm and have 2-3 leaves scattered are divided from the mother plant in batches and transplanted to the soil made of peat. : In the matrix of perlite with a volume ratio o...

Embodiment 2

[0022] Embodiment 2: (a kind of method 2 that improves the reproduction coefficient of Radix glabrata)

[0023] In this example, step (1) selects the bright-leaved lotus seedling with 7 leaves and a crown diameter of 30cm as the mother plant; step (2) uses 15% paclobutrazol as the plant growth regulator, and prepares 100ppm of Medicinal solution; step (3) spray 100ppm paclobutrazol solution evenly to the leaf surface according to the dosage of 20ml / per plant; step (4) obtain 1.7 new seedlings on average per plant, and its annual reproduction coefficient reaches 3.4; the remaining steps are the same as the implementation example 1.

Embodiment 3

[0024] Embodiment 3: (a method 3 for improving the reproduction coefficient of Radix glabrata)

[0025] In this example, step (1) selects the bright-leaved glaucous calyx hemp seedling with 8 leaves and a crown diameter of 40 cm as the mother plant; step (2) uses 15% paclobutrazol as the plant growth regulator, and prepares a 150ppm drug with purified water liquid; step (3) evenly spray the paclobutrazol solution of 150ppm to the leaf surface according to the dosage of 20ml / per plant; step (4) obtain 3.1 new seedlings on average per plant, and its annual reproduction coefficient reaches 6.2; the remaining steps and processes are the same as in the embodiment 1.

Abstract

The invention discloses a method for improving propagation coefficient of Aechmea with bright leaves, and belongs to the technical field of flower seedling breeding. The method comprises the following steps of: (1) preparing a parent plant; (2) determining the type and concentration of a plant growth regulator; (3) applying the plant growth regulator; and (4) dividing the plant and transplanting.By adopting the method disclosed by the invention, the propagation coefficient of Aechmea with bright leaves is obviously improved, the annual propagation coefficient is improved to 4-6 from 2-3, a difficult situation that market development requirement can not be met as propagation of the Aechmea with bright leaves is difficult is overcome, and the method disclosed by the invention has the advantages of simplicity and convenience in operation, good propagation seedling quality and the like. The method disclosed by the invention can be popularized and applied in a flower planting region and aflower company.

Description

technical field [0001] The invention relates to the technical field of reproduction of flower seedlings, in particular to a method for improving the reproduction coefficient of ornamental pineapple bright-leaved lotus. Background technique [0002] Bright-leaved calyx ( Aechmea victoriana var. discolor ) is a foliage-viewing and fruit-viewing variety in the family Bromeliaceae. It is a new ornamental pineapple species. It grows fast and blooms easily. It does not need very strict cultivation conditions and technical management. Successfully cultivated, it is very suitable for potted plants for family flower lovers. The plant type of this variety is medium, the crown diameter is about 50cm; the leaves are wide, the leaf surface is dark green, the leaf back is purple red, and both sides of the leaf are very bright, as if coated with brightener; compound spikes, small flowers are sessile, sepals Conjoined, calyx tip blue; false fruit ovate, larger base, 0.8-1cm in diameter; p...
