Domestication method of wild selenium-rich shitake strain

Abstract

The invention relates to the technical field of the breeding of edible mushroom strains and particularly relates to a domestication method of a wild selenium-rich shitake strain. The domestication method comprises the following steps: (S2) seeding mushroom selection, (S2) seeding mushroom pretreatment, (S3) tissue separation, (S4) tissue culture, (S5) rotary tube culture and (S6) oblique surface repeated culture. According to the domestication method, a wild excellent shitake body concomitant with a tree in a selenium-rich mountainous area is taken as a seeding mushroom during the seed selection, tree leaf liquid and a selenium-rich nutrient solution are added into a culture medium in the domestication culture process, and the proportions of the tree leaf liquid and the selenium-rich nutrient solution are continuously adjusted, so that the adaptability of the wild selenium-rich shitake strain to the culture mediums, namely tree flour and the selenium-rich nutrient is improved, the absorption rate of the domesticated shitake strain to the selenium-rich nutrient is increased, the degeneration speed is decreased, the stress resistance is improved, the pollution possibility is reduced,and the pertinence is strong; and meanwhile, the quality and flavor of the shitake strain are improved, and the method is high in economic benefit and has practical guiding significances and popularization and application values.

Description

technical field [0001] The invention relates to the technical field of edible fungus strain breeding, in particular to a domestication method of wild selenium-enriched shiitake mushroom strains. Background technique [0002] The output of shiitake mushrooms ranks second in the world's artificially cultivated edible fungi. With the improvement of the quality of life, people began to gradually realize the nutritional value of shiitake mushrooms. Due to its unique flavor and the effect of enhancing human immune function, it has become one of people's favorite health foods. [0003] In recent years, due to the shortage of wild shiitake mushrooms in the market, shiitake mushrooms have gradually changed from natural growth in the wild to artificial domestication cultivation, so the output of shiitake mushrooms has increased significantly. In order to better meet the growing market demand, more and more Farmers use various chemical fertilizers and pesticides in order to increase p...

Problems solved by technology

However, the current research on selenium-enriched shiitake mushrooms mainly focuses on the cultivation of selenium-enriched shiitake mushrooms, and there are few studies on the domestication of wild selenium-enriched shiitake mushrooms.

At the same time, although the shiitake mushrooms studied and produced have a high selenium content, the flavor and quality of the shiitake mushrooms are poor, and the absorption and utilization rate of selenium fertilizers is low. There are also problems that the shiitake mushroom strains in production are easy to degrade, be polluted, and have poor stress resistance. The shortcomings, did not fundamentally solve the problem
