Problems solved by technology

[0005] The present invention makes Auricularia auricosa and associated pilus Bastasis into cultivars respectively by means of seed production respectively, and solves the low rate of auricularia and low rate of auricularia in the original seed production due to uneven growth and not exuberant growth of Auricularia auricula by mixing technology. The problem of low yield

Abstract

The invention discloses a preparation method of a cultivated strain of tremella aurantialba. The preparation method is characterized by comprising steps as follows: strain culture: solid culture and liquid culture of Stereum hirsutum as a first component of the cultivated strain of the tremella aurantialba; test tube seed culture, liquid seed culture, shaking culture and fermentation tank culture of tremella aurantialba yeast-like conidia as a second component of the cultivated strain of the tremella aurantialba; mixing of the first component and the second component of the cultivated strain of the tremella aurantialba; processes of cut-log cultivation and cultivation in a bag or a bottle. The tremella aurantialba and the companion fungi, namely the Stereum hirsutum, in the cultivation of the tremella aurantialba are cultured respectively, the tremella aurantialba and the companion fungi can be sufficiently and uniformly mixed, so that the yeast-like conidia of the tremella aurantialba can germinate sufficiently, the frequent condition that a large quantity of Stereum hirsutum sporocarps grow on cut-logs in the cultivation of the tremella aurantialba can be prevented, with the application of the strain, the fruiting rate of the cut-log cultivation of the tremella aurantialba is higher than 95%, and the yield is increased by 15%-20%; with the application of the liquid-liquid strain of the tremella aurantialba, the tremella aurantialba and the companion fungi are uniformly mixed, during cultivation in the bag or the bottle, the tremella aurantialba spawn running is fast, the colonization is fast quickly, the pollution rate is low, the fruiting rate is up to 100%, the color change is fast, and the growing period is short.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a method for preparing a golden ear cultivar of a large fungus with associated bacteria. Background technique [0002] Tremella aurantial (Tremella aurantial ba Bandoniet Zang) is an edible and medicinal fungus of the genus Tremella aurantiaceae Tremellaceae of Basidiomycetes. It is mainly distributed in Southwest my country. Tremella aurantium has been successfully artificially cultivated (including section wood and bag material cultivation). [0003] Because golden ear has poor utilization ability to lignin and cellulose, it needs to rely on Stereumhirsutum (willd: Fr.) S.F.Gray) associated with it to provide nutrition under natural conditions to grow. Because Auricularia hyphae are weaker, in the existing cultivar seed production process, the situation that Bacillus chamomile grows rapidly and Auricularia auricula does not grow often occurs, thus resulting in...
