Embodiment 1

[0025] A method for growing seedlings of Phoebe bournei using arbuscular mycorrhizal fungi, including microbial propagation, seed treatment, sand bed accelerating germination, seedling substrate preparation, fungal inoculation and seedling management, selecting suitable seeds for disinfection and accelerating germination. Phoebe bournei sprouts are inoculated with arbuscular mycorrhizal fungi when they are transferred to the seedling substrate, and high-quality Phoebe bournei container seedlings can be obtained through seedling management. The main steps are as follows:

[0026] (1) Bacteria expansion:

[0027] ① Fill the sterilized boiling sand culture medium to 2 / 3 of a plastic basin with a diameter of 16 cm and a height of 14 cm. Spread 15 g of arbuscular mycorrhizal fungal inoculants evenly on the sterilized boiling sand culture medium, and then plant Put on the clover bulbs, and then cover the sterilized boiling sand culture medium with a thickness of 2 cm, pour it through wat...

Abstract

The invention discloses a Phoebe bournei seedling cultivation method by using arbuscular mycorrhizal fungi, which comprises steps of microbial inoculum propagation, seed treatment, sand bed germination, seedling cultivation matrix preparation, fungi inoculation and seedling stage management. Suitable seeds are selected for disinfection treatment and then germination, arbuscular mycorrhizal fungi inoculation is carried out when the Phoebe bournei bud seedling is transplanted to the seedling cultivation matrix, and a high-quality Phoebe bournei container seedling is acquired through the seedlingstage management. The Phoebe bournei bud seedling is inoculated with the arbuscular mycorrhizal fungi to form ectotrophic mycorrhiza, the Phoebe bournei plant is helped to absorb nutrients and water,the resistance of the plant is enhanced, the quality of the plant is further improved, the operation is simple and convenient, the cost is low, and the economic, social and ecological benefits are good.

Description

Technical field [0001] The invention belongs to the technical field of plant cultivation, and particularly relates to a method for raising seedlings of Phoebe bournei using arbuscular mycorrhizal fungi. Background technique [0002] South Fujian ( Phoebe bournei (Hemsl.) Yang) Lauraceae, Phoebe genus is an evergreen large tree, up to 20 meters high, 2.5 meters in diameter at breast height, straight trunk, dense crown, pale yellow bark, flaky peeling, branchlets with pilose or close Glossy, winter buds are gray-brown pilose, and its leaves are leathery, lanceolate or oblanceolate. The panicles are born in the middle and lower leaf axils of new branches. Phoebe Phoebe is a unique tree species in China. It belongs to the second-level national protected wild plant. It loves humidity and is shade-tolerant and avoids glare. It is mainly distributed in Guangxi, Guizhou, Hunan, Hubei, Jiangxi, Zhejiang and Fujian. It is also commonly known as Phoebe nanmu, which is aromatic and durable...
