Embodiment 1

[0027] Embodiment 1 Hardwood cuttings take root in spring

[0028] (1) Material selection: Collect healthy, full-bodied, disease-free branches and cut cuttings in mid-March. The thickness of the cuttings is 0.35-0.55 cm, and the length is 8-12 cm. The cuttings are required to have at least two pairs of buds; the cuts on the cuttings are cut flat , the lower incision is obliquely cut, cut into a 45-50° slope, and the distance between the upper and lower incisions is about 1.5cm from the buds; for evergreen and tender branch cuttings, keep 1 to 2 leaflets on the upper part of the cuttings, and keep 1 / 3 to 1 / 2 of the leaf area. The cut cuttings are bundled every 30 branches.

[0029] (2) Hormone treatment: use 100mg·L of cut cuttings (hard branch cuttings) -1 IAA soaked for 180min; treated with clear water (CK) as a control.

[0030] (3) Seedbed laying: the seedbed is an open-air seedbed, brick-concrete structure, 45cm high, and a shading net is built on its top, with a gap spr...

Embodiment 2

[0038] Example 2 Summer twig cuttings take root

[0039] (1) Material selection: In mid-August, healthy and plump branches, free from diseases and insect pests, are collected and cut into cuttings. The thickness of the cuttings is 0.35-0.55 cm, and the length is 8-12 cm. The cuttings are required to have at least two pairs of buds; the cuts on the cuttings are cut flat. , the lower incision is obliquely cut, cut into a 45-50° slope, and the distance between the upper and lower incisions is about 1.5cm from the buds; for evergreen and tender branch cuttings, keep 1 to 2 leaflets on the upper part of the cuttings, and keep 1 / 3 to 1 / 2 of the leaf area. The cut cuttings are bundled every 30 branches.

[0040](2) Hormone treatment: use 300mg·L of cut cuttings (twig cuttings) -1 soaked in IAA for 30 minutes; treated with clear water (CK) as a control.

[0041] (3) Seedbed laying: the seedbed is an open-air seedbed, brick-concrete structure, 45cm high, and a shading net is built on...

Abstract

The invention discloses a cuttage propagation rooting method of cornus kousa and belongs to the technical field of plant planting. The cuttage propagation rooting method of cornus kousa comprises material selection, hormone treatment, seedbed laying, application of a cuttage approach, management after cuttage, dynamic observation of cutting rooting after cuttage, statistics and measurement of related indexes. According to the cuttage propagation rooting method of cornus kousa, the rooting rate is high, and the rooting index is great.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a cutting propagation and rooting method of Sizhaohua. Background technique [0002] Cornus (Cornus) is a deciduous or evergreen small tree or shrub of Cornaceae (Cornaceae). named after the film. Sizhaohua has a beautiful tree shape and distinct layers. It also gathers colorful flowers, colorful fruits, and colorful leaves. It can be planted in clusters on roadsides, lawns, forest edge pools, or isolated in front of halls, pavilions, and pavilions; its cultivated species The color is richer, and it is a horticultural ornamental tree species with good development prospects. Sizhaohua also exerts good ecological benefits in the forest ecosystem. The whole plant of Sizhaohua can be used as medicine, which has the medicinal value of warming the stomach, promoting menstruation, promoting blood circulation, anti-inflammatory and reducing swelling; the fruit of Sizhaohua is s...
