Problems solved by technology

[0003] At present, due to the large size of the cultivated oyster mushroom buds, yellow mushrooms are prone to dead mushrooms. Although the occurrence of this situation can be reduced by greening the oyster mushroom buds, it is a waste of a lot of manpower
The mycelium of Pleurotus ostreatus is generally obtained directly from young tissues such as fruiting bodies and fungal cords. The use of this mycelium cultivation has the following disadvantages: high pollution rate, low biotransformation rate of the first stubble, and heavy pests and diseases.

Embodiment 1

[0035] The breeding method of oyster mushroom, comprises the following steps:

[0036] (a), collect the spores of Pleurotus ostreatus from the sporocarps of Pleurotus ostreatus with multiple excellent properties, sprinkle water on fresh broad-leaved wood, the growth humidity of spores is 60%, and the temperature is 15°C, grow to the sporocarps of Pleurotus ostreatus in maturity

[0037] (b), the fruiting body of Pleurotus ostreatus with a maturity of 70% is cut to obtain the bacterial flesh tissue, and the bacterial flesh tissue is cultivated in a PDA medium to obtain mycelium;

[0038] (c), select the mycelium that grows for 5 days to slice, and the thickness of mycelium slice is 0.2mm, and mycelia slice is cultivated in PDA medium, and the mycelium that obtains after cultivating is the strain of oyster mushroom.

Embodiment 2

[0040] The breeding method of oyster mushroom, comprises the following steps:

[0041] (a), collect the spores of Pleurotus ostreatus from the sporocarps of Pleurotus ostreatus with a plurality of excellent properties, sprinkle water on fresh broad-leaved wood, the growth humidity of spores is 70%, and the temperature is 25°C, grow to the sporocarps of Pleurotus ostreatus in maturity

[0042] (b), the fruiting body of Pleurotus ostreatus with a maturity of 80% is cut to obtain the bacterial flesh tissue, and the bacterial flesh tissue is cultivated in a PDA medium to obtain mycelium;

[0043] (c), select the mycelium that grows for 6 days to slice, and the thickness of mycelium slice is 0.4mm, and mycelia slice is cultivated in PDA medium, and the mycelium that obtains after cultivating is the bacterial classification of oyster mushroom.

Embodiment 3

[0045] The breeding method of oyster mushroom, comprises the following steps:

[0046] (a), collect the spores of Pleurotus ostreatus from the sporocarps of Pleurotus ostreatus with a plurality of excellent properties, sprinkle water on fresh hardwood, the growth humidity of spores is 85%, and the temperature is 35°C, grow to the sporocarps of Pleurotus ostreatus in maturity

[0047] (b), the fruiting body of Pleurotus ostreatus with a maturity of 7-80% is cut to obtain the bacterial flesh tissue, and the bacterial flesh tissue is cultivated in a PDA medium to obtain mycelium;

[0048] (c), select the mycelium that grows for 7 days to slice, and the thickness of mycelium slice is 1mm, and mycelium slice is cultivated in PDA medium, and the mycelium that obtains after cultivating is the strain of oyster mushroom.

[0049]The Pleurotus ostreatus bacterial classification that embodiment 1-3 obtains is cultivated and obtained Pleurotus ostreatus sporocarps, and culture method is ...

Abstract

The invention relates to the field of edible mushroom breeding, in particular to an oyster mushroom breeding method. The oyster mushroom breeding method includes the following steps that oyster mushroom spores are collected and sown and grow into oyster mushroom fruit bodies in the mature period, mushroom context tissues are cut from the oyster mushroom fruit bodies for cultivation, then hyphae are obtained, the hyphae are cut into slices for cultivation, and the obtained hyphae are oyster mushroom cultures. According to the oyster mushroom breeding method, the hyphae are changed by a physical technological means, the hyphae meet the requirement gradually, and differentiation of the fruit bodies is decreased; the prepared cultures are used for cultivation, good disease resistance and insect resistance are achieved, and the oyster mushroom fruit bodies obtained by planting are thick in hull, deep in color, big, fleshy, not prone to being over ripe, glossy, shiny, rich in mushroom flavor and delicious in taste; the biotransformation efficiency of the first crop of oyster mushrooms reaches up to 70%, differentiation of the fruit bodies is effectively reduced by 30%, yellow mushrooms and dead mushrooms are avoided in the whole growth process, bud removal is avoided, and labor is saved.

Description

technical field [0001] The invention relates to the field of edible fungus breeding, in particular to a breeding method of oyster mushrooms. Background technique [0002] Pleurotus ostreatus contains a variety of vitamins and high mineral content. Among them, the content of vitamin B1 and B2 is higher than that of meat, and the content of vitamin B12 is higher than that of cheese. There is no starch in the flat mushroom, and the fat content is very small (only 1.6% of the dry matter). It is known as "safe food", "healthy food", especially the ideal food for patients with diabetes and obesity. The physiologically active substances of various special components such as pleuromicin and pleurotus polysaccharide in Pleurotus ostreatus have the functions of inducing interferon synthesis, strengthening the body's immunity, the body's ability to resist cancer, and reducing blood cholesterol. Therefore, eating more oyster mushrooms can prevent and treat hypertension, cardiovascular...
