Embodiment 1

[0029] Embodiment 1: A kind of method of applying arbuscular mycorrhizal fungus technology to cultivate Panax notoginseng

[0030] (1) Bacterial inoculum production:

[0031] The susceptible crop white-flowered clover was planted by inoculating the disinfected soil with Glomus mossea inoculum, and the fibrous roots of plants with high infestation degree and the soil containing mycorrhizal spores were used as inoculants. The culture substrate is a mixture of sand: zeolite: soil = 1:1:1. The particle size of the sand is 0.5mm; the particle size of the zeolite is 2mm; the basic physical and chemical properties of the soil are: organic matter 3.66%, total nitrogen 0.17%, total phosphorus 0.12%, total potassium 1.30%, alkaline nitrogen 172.01mg / kg, available phosphorus 14.21mg / kg, available potassium 145.13mg / kg, pH 5.7.

[0032] (2) Symbiotic cultivation of Panax notoginseng and bacteria: Disinfect the soil with 0.1% formaldehyde. After the disinfection, the soil is air-dried fo...

[0034] Embodiment 2: A method for cultivating Radix Notoginseng using arbuscular mycorrhizal fungi technology

[0035] (1) Bacterial inoculum production:

[0036] The susceptible crop ryegrass was planted by inoculating the disinfected soil with Glomus mossea inoculum, and the fibrous roots of plants with high infestation degree and the soil containing mycorrhizal spores were used as inoculants. The culture substrate is a mixture of sand:zeolite:soil=1:1:2.5. The sand particle size is 1mm; the zeolite particle size is 3mm; the basic physical and chemical properties of the soil are: organic matter 3.13%, total nitrogen 0.11%, total phosphorus 0.10%, total potassium 1.07%, alkali-hydrolyzed nitrogen 155.56mg / kg, available phosphorus 8.55 mg / kg, available potassium 122.78mg / kg, pH 5.5.

[0037] (2) Symbiotic cultivation of Panax notoginseng and bacteria: Disinfect the soil with 0.1% formaldehyde. After the disinfection, the soil is aired for 10 days and then placed in a plastic...

[0039] Example 3: A method of cultivating Panax notoginseng using arbuscular mycorrhizal fungi technology

[0040] (1) Bacterial inoculum production:

[0041] The susceptible crop corn was planted by inoculating the disinfected soil with Glomus mossea fungus, and the highly infested plant fibrous roots and the soil containing mycorrhizal spores were used as inoculants. The culture substrate is a mixture of sand: zeolite: soil = 1:1:3. Sand particle size: 0.5-1mm; the zeolite particle size: 2-3mm; the basic physical and chemical properties of the soil are: organic matter 5.24%, total nitrogen 0.23%, total phosphorus 0.26%, total potassium 2.21%, alkali-hydrolyzed nitrogen 180.31mg / kg, available phosphorus 15.39mg / kg, available potassium 160.00mg / kg, pH 5.9.

[0042] (2) Symbiotic cultivation of Panax notoginseng and bacteria: Disinfect the soil with 0.1% formaldehyde, put the soil in the air for 10 days after disinfection, put it in a plastic pot, sprinkle the inoculum in the p...

Abstract

A method for cultivating Panax notoginseng by an arbuscular mycorrhizal fungi technique includes the steps: firstly, producing inoculants, planting sensitive plants after arbuscular mycorrhizal fungi of Glomus are inoculated to disinfected soil, and using high-infection-rate plant fibril and soil containing mycorrhiza spores as the inoculants; and secondly, performing symbiotic cultivation of Panax notoginseng and mycorrhizae, scattering the inoculants into the soil, covering with earth, sowing seeds of Panax notoginseng, covering with earth, covering with pine needles, moving to a shade, and keeping soil water content to be 25%-35%. By the novel method, disease incidence of Panax notoginseng seedlings can be reduced, seedling survival rate of annual Panax notoginseng can be increased evidently, yield and quality of biennial Panax notoginseng can be increased evidently, usage amount of pesticides and fertilizers in cultivation of Panax notoginseng can be reduced, and both quality and yield of Panax notoginseng are increased.

Description

technical field [0001] The invention relates to a Panax notoginseng cultivation technique, in particular to a method for cultivating Panax notoginseng by applying the technology of arbuscular mycorrhizal fungi, and belongs to the technical field of traditional Chinese medicine cultivation. Background technique [0002] Panax notoginseng, also known as Tianqi, and its Latin scientific name is Panax notoginseng (Bruk) F.H.Chen, is a plant of the genus Araliaceae. Modern pharmacological research has found that Panax notoginseng has significant effects on the prevention and treatment of cardiovascular and cerebrovascular diseases, and it also has good effects on enhancing human immunity, delaying aging, anti-fatigue, and anti-tumor. [0003] Due to the particularity of the growing environment of Panax notoginseng and the singleness of varieties, the continuous cropping of Panax notoginseng has been hindered, which has seriously affected the yield and quality of Panax notoginseng...
