Embodiment Construction

[0034] The present invention will be described in detail below in combination with specific embodiments.

[0035] The invention provides a method for cultivating mycorrhizal seedlings of Chestnut truffles based on a symbiotic relationship, which is specifically implemented according to the following steps:

[0036] 1. Cultivate semi-sterile chestnut seedlings;

[0037] 1.1. Preservation of tuberaestivum strains: purchase fresh and mature tuberaestivum from the market, wipe off the sediment and put them in ziplock bags, and store them in a low-temperature freezer at -18°C;

[0038] Selection of symbiotic tree species: select chestnut (Castanea mollissima) that can form mycorrhizae with truffles and produce fruiting bodies;

[0039] 1.2. Substrate preparation: Mix vermiculite and YC / T310-2009 standard tobacco floating seedling cultivation substrate at a volume ratio of 1:1, add an appropriate amount of water and mix evenly, the moisture content is about 28%, that is, the substr...

Abstract

The invention discloses a Chinese chestnut summer truffle mycorrhizal seedling culture method based on the symbiotic relation. The method specifically includes the following steps that semi-aseptic seedlings are cultured, and Chinese chestnut semi-aseptic seedlings are obtained through preparation; an inoculation solution and an inoculation matrix are prepared, and seedling culture trays are prepared; summer truffle inoculation treatment is performed; post-inoculation management is performed; the humidity of the matrix is controlled, proper ventilation is performed, and a certain temperature and a certain air humidity are kept; mycorrhizae are checked and planted outdoors. According to the culture method, the mycorrhizal seedlings can increase the survival rate of afforestation of Chinese chestnut trees; the mycorrhizae can increase the absorption area of root systems of the Chinese chestnut trees, promote growth and development of the Chinese chestnut trees and increase the yield of Chinese chestnuts; the Chinese chestnut summer truffle mycorrhizal seedlings achieve the overground and underground joint earnings, increase the utilization rate of land and increase the economic benefit per unit land area.

Description

technical field [0001] The invention belongs to the technical field of forestry economic forest seedling cultivation and the technical field of microbes, and specifically relates to a method for cultivating mycorrhizal seedlings of Chestnut truffles based on a symbiotic relationship. Background technique [0002] At present, the cultivation of chestnut seedlings all over the country adopts conventional seedling raising techniques. The chestnut trees bear fruit 5-7 years after the seedlings are afforested, and the economic benefits are only chestnuts, and the source of economic benefits per unit area is single. Moreover, truffles belong to the Ascomycetes (Ascomycets) Truffles (Tubrales) Truffles (Tuberaceae) Truffles (TuberF.H.Wigg) currently only rely on natural wild resources to supply the market. Due to the particularity of the growth of truffles, the excavation will cause serious damage to the bacteria pond and the ecological environment, so that the output of truffles w...
