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, the present embodiment 1 uses peat soil, river sand, humus and mixed substrates (peat soil, river sand, and humus are mixed in a volume ratio of 2:2:1). 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

[0037]①Use Glomus mosei as the first b...

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 of Atractylodes atractylodes seedlings, which belongs to the field of processing Atractylodes rhizomes. The method adopts Glomus mosesi as the first strain and Glomus tetus as the second strain, and treats The first strain and the second strain are mixed after a unique propagation work, and the obtained arbuscular mycorrhizal fungus propagation mixture is applied to the Atractylodes macrocephala seedling substrate added with dry chicken manure, and the cerium chloride solution is used to Treat Atractylodes macrocephala seeds, and spray Atractylodes atractylodes seedlings with special spraying water, thus overcoming the problems in the prior art that Atractylodes atractylodes is severely degraded after multiple generations of reproduction, resulting in weakened resistance, reduced quality, and high seedling mortality. Further, the growth ability and drought resistance ability of Atractylodes macrocephala seedlings are significantly improved, and seedlings with strong growth ability and drought resistance ability can be provided for Atractylodes rhizome production, thereby expanding the development of Atractylodes rhizome production and expanding the development and utilization of Atractylodes rhizome resources.

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. Distributed in Jiangsu, Zhejiang, Fujian, Jiangxi, Anhui, Sichuan, Hubei, Hunan and other places in China, this ...
