Embodiment 1

[0020] Embodiment 1. A method for cultivating salt-tolerant heather, specifically:

[0021] (1) Select new branches of Photinia radiata with a length of 3-5cm, and cut the branches upside down in the rooting medium with a cutting depth of 0.5cm. The rooting medium is composed of MS+1.3mg / L activated carbon and cultivated in a dark place 3 days, forming root shoots with a length of 0.3cm;

[0022] (2) Take the shoots out of the rooting medium, rinse the cutting parts, and re-upright the cuttings in the rooting medium. The rooting medium consists of MS+4mg / L solanine, at 6°C, use Infrared light irradiation treatment with a wavelength of 1 μm and a power of 10W for 48 hours;

[0023] (3) Take the shoots out of the root-increasing medium, rinse the cutting parts, and re-upright the cuttings in the strong root medium. The strong root medium consists of MS+10mg / L vitamin P, at 26°C, every Every 3 hours, irradiate the roots of cutting branches with blue light with an intensity of 5...

Embodiment 2

[0026] Embodiment 2, a method for cultivating salt-tolerant heather, specifically:

[0027] (1) Select new branches of Photinia radiata with a length of 3-5cm, and cut the branches upside down in the rooting medium with a cutting depth of 0.8cm. The rooting medium is composed of MS+1.5mg / L activated carbon and cultivated in a dark place 5 days, forming root shoots with a length of 0.6cm;

[0028] (2) Take the shoots out of the rooting medium, rinse the cutting parts, and re-upright the cuttings in the rooting medium. The rooting medium consists of MS+5mg / L solanine, at 8°C, with Infrared light irradiation treatment with a wavelength of 2 μm and a power of 12W for 50 hours;

[0029] (3) Take the shoots out of the root-increasing medium, rinse the cutting parts, and re-upright the cuttings in the strong root medium. The strong root medium consists of MS+12mg / L vitamin P, at 28°C, every Every 5 hours, irradiate the roots of cutting branches with blue light with an intensity of ...

Abstract

The invention relates to the technical field of agricultural planting, in particular to a cultivation method of salt-tolerant Photinia serrulata, comprising the specific steps of inserting cuttings of shoots of Photinia serrulata in a rooting medium of MS (Murashige and Skoog) and 1.3-1.5 mg / L activated carbon for the purpose of rooting culture, placing in a root enrichment medium of MS and 4-5 mg / L solanine for the purpose of root enrichment culture, placing in a root strengthening medium of MS and 10-12 mg / L vitamin P for the purpose of root strengthening culture, and placing in a medium of seaweed pulp and 0.5-0.8 mg / L metronidazole for the purpose of induced culture. Plants of Photinia serrulata cultivated by the cultivation method have great salt tolerance and have a survival rate of 90.2% and above after being transplanted to saline-alkaline lands.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for cultivating salt-tolerant heather. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. The saline-alkali soil has high salt content, a pH value as high as 8-10, poor soil air permeability, poor structure, and extremely low soil microbial content. , In this harsh soil environment, it is difficult for general greening plants to survive, which undoubtedly poses a great threat to greening and beautifying the environment. [0003] Photinia is a woody plant, an evergreen tree, with strong germination ability, pruning resistance, and certain resistance to smoke and toxic gases. It is rich in ornamental value and can also be used for medicinal purposes. It likes warm and humid climate, not strong cold resistance, light-loving and shade-tolerant. ...
