Problems solved by technology

[0006] In view of the above-mentioned problems, the present invention provides a method for improving the growth and drought resistance of Atractylodes macrocephala seedlings, so as to overcome the weakening of resistance and the decline in quality of Atractylodes rhizome in the prior art due to the serious degradation of the species after multi-generation propagation. Therefore, it can significantly improve the growth ability and drought resistance of Atractylodes rhizome seedlings, and provide seedlings with strong growth and drought resistance for Atractylodes rhizome production, thereby expanding the development of Atractylodes rhizome production and expanding the development and utilization of Atractylodes rhizome resources

Embodiment 1

[0034] Embodiment 1: the selection of the propagation substrate of arbuscular mycorrhizal fungus

[0035] In order to select the best substrate for the propagation of arbuscular mycorrhizal fungi, peat soil, river sand, humus and mixed substrates (peat soil, river sand, and humus are mixed in a volume ratio of 2:2:1) were used in Example 1. Four kinds of propagation substrates for the first strain "Glomus moses" and the second strain "Globus moses" are put into the autoclave after passing through a 20-mesh sieve. Sterilize at 121°C for 20 minutes to completely kill the arbuscular mycorrhizal fungi in the propagation substrates, and dry the sterilized four propagation substrates for later use.

[0036] The expansion of arbuscular mycorrhizal fungi includes the expansion of the first arbuscular mycorrhizal fungi and the expansion of the second arbuscular mycorrhizal fungi; a: the expansion of the first arbuscular mycorrhizal fungi

Embodiment 2

[0050] Example 2: Selection of Host Plants for the Propagation of Glomus mosei and Glomus juniperus

[0051] Glomus mosesi and Glomus juveniles are both arbuscular mycorrhizal fungi that need to live in symbiosis with plant roots, so choosing a suitable host plant is crucial for the proliferation of Glomus moses and Glomus juveniles. White clover and wheat were selected as hosts, Glomus mosseae and Glomus ovata were selected as strains, and a mixed substrate (peat soil, river sand, and humus in a volume ratio of 2:2:1 was selected) Mixed) as the propagation substrate of Glomus moses and Glomus juveniles, a total of 6 pots are needed, three pots adopt Glomus moses, and the other three pots use Glomus juveniles, and 20g strains are put in each pot of 3kg substrate (Glomus mosesi or Glomus juniperis), sterilized white clover and wheat seeds with 10% hydrogen peroxide for 15 minutes, sowed white clover and wheat alone, and mixed planting of white clover and wheat at a ratio of 1:1...

Embodiment 3

[0059] Embodiment 3: the influence of different cerium chloride concentrations on the germination of Atractylodes macrocephala seeds

[0060] Select plump Atractylodes macrocephala seeds, prepare 1, 3, 6, 9, and 12mmol / L cerium chloride solutions respectively, soak the Atractylodes macrocephala seeds in different concentrations of cerium chloride solutions for 2 hours, and then rinse the Atractylodes macrocephala seeds twice with clean water for backup use. Choose loose sandy conglomerate soil with good air permeability as the Atractylodes macrocephala seedling substrate, and add 50-100g of decomposed dried chicken manure to each pot. Mix the same amount of saccharomyces strains, sprinkle them evenly in the flowerpots, 30-50g per pot, then fill the flowerpots with the Atractylodes macrocephala seedling substrate, and finally sprinkle the Atractylodes macrocephala seeds soaked in the rare earth solution on the surface of the substrate, and use a little Atractylodes macrocephala...

Abstract

The invention relates to a method for improving the growth and drought-resistance capacity of rhizoma atractylodis seedlings, and belongs to the field of treatment of rhizoma atractylodis seedlings. In the method, glomus mosseae are adopted as first strains, glomus etunicatum is adopted as second strains, unique propagation expanding work and mixing are performed on the first strains and the second strains in sequence, an obtained arbuscular mycorrhizal fungus propagation expanding mixture is applied to a rhizoma atractylodis seedling substrate in which dry fowl manure is added, rhizoma atractylodis seeds are treated with a cerium chloride solution, and the rhizoma atractylodis seedlings are sprayed with specific spraying water. In this way, the defects are overcome that in the prior art,severe genetic depression occurs after multi-generation culturing of rhizoma atractylodis, as a result, the resistance of the rhizoma atractylodis is weakened, quality is lowered, and the death rate of the seedlings is high; then the growth and drought-resistance capacity of rhizoma atractylodis seedlings is remarkably improved, the seedlings which are high in growth and drought-resistance capacity of rhizoma atractylodis seedlings can be provided for rhizoma atractylodis production, accordingly the development of rhizoma atractylodis production is expanded, and the development and utilizationof rhizoma atractylodis resources are expanded.

Description

technical field [0001] The invention relates to the technical field of treatment of Atractylodes rhizome seedlings, in particular to a method for improving the growth and drought resistance of Atractylodes rhizome seedlings. Background technique [0002] Atractylodes macrocephala (scientific name: Atractylodes macrocephalaKoidz.): Atractylodes macrocephala is a perennial herb of the genus Atractylodes, up to 60 cm high, with nodular rhizomes. Stems erect, all smooth and glabrous. Alternate leaves, pinnatisect leaves, side lobes oblanceolate, oval or oblong, top lobe larger than side lobes, all leaves are thin, papery, green on both sides, glabrous, capitulum solitary stem The top of the branches, the bracts are green, needle-like and pinnatifid. Involucre broadly bell-shaped, apex purple-red. The achene is obconic, and blooms and bears fruit in August-October.
