Seed production method for edible fungus cultispecies, prepared cultispecies, and edible fungus cultivation method

Abstract

The invention relates to the technical field of edible fungus cultivation, and especially relates to a seed production method for an edible fungus cultispecies, a prepared cultispecies, and an edible fungus cultivation method. In the cultispecies prepared by the method, distribution of hypha is more uniform. Take tremella fuciformis for example, in the cultispecies of the tremella fuciformis, hypha distribution of tremella fuciformis is uniform, and proportion of the hypha and companion fungus is appropriate. Using the hypha as the cultispecies in production, tremella growing rate after inoculation is obviously improved, phenomenon of tremella bar cavity is reduced, and biotransformation efficiency of tremella bars is improved, and income of farmer households is increased.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a seed production method of edible fungus cultivars, the prepared cultivars and the edible fungus cultivation method. Background technique [0002] Edible fungi are large fungi with fleshy or gelatinous fruiting bodies that are edible by humans. China is very rich in edible fungus resources. According to statistics in 2000, there were 938 kinds of edible fungi in China, and more than 50 kinds were artificially cultivated. The edible part of edible fungus is the fruiting body with spore-forming structure, the protein content of the fruiting body is about 3-4% of the fresh weight or 20-40% of the dry weight, it contains a complete range of amino acids, and there are more nucleic acids and Various vitamins, including vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin PP (niacin), vitamin C (ascorbic acid) and vitamin D (ergosterol), etc. The content of miner...

Problems solved by technology

[0005] Taking white fungus as an example, although the mycelium growth range of its associated fungus (Ash fungus) can spread all over the whole fungus bag, the growth range of the white fungus mycelium can only extend about 2cm outward at the inoculation point, while the usual fungus bag or mushroom The diameter of the bottle is not less than 8cm; this leads to the growth of the mycelium of the associated bacteria on the side far away from the center of the fungus bag, but no white fungus mycelium or golden fungus mycelium

For edible fungi, inoculation is usually carried out in two ways, one is to inoculate by breaking blocks, because it is not possible to distinguish Tremella mycelia, golden fungus mycelia and their associated mycelia, and it is easy to have cavities, that is, There are only associated hyphae in the inoculation hole; one is to plant the sawdust through a tool shaped like a funnel after being completely finely milled, which can easily cause damage to the mycelia and reduce activity, and at the same time it is very easy to have only a small amount of white fungus or fungus in the inoculation hole. Phenomenon of golden ear hyphae

After that, the yield rate of Duanmu will be much lower than expected, which means that the production materials will be wasted, and the efforts of the growers will be disappointed. tremella demand

Of course, there are some growers who are familiar with the biological characteristics of Tremella or Golden Fungus, so when he uses the existing cultivars on the market, he will throw away some sawdust that only contains pure associated mycelium, and the cost will increase significantly.
