Embodiment 1

[0043] Example 1 High-yield Cultivation of Pleasant Mushroom

[0044] (1) Culture medium preparation

[0045] Medium A, each 1000ml of culture medium contains 120.0g of potato, 100g of black plum waste branch sawdust, 20.0g of potassium humate, 0.5g of peptone, 2.5g of soybean powder, 3.0g of potassium dihydrogen phosphate, and 1.5g of magnesium sulfate 1. Sucrose 25.0g, water 700-900ml, set the volume to 1000ml, adjust the pH to 6.5-7.0.

[0046] Culture medium A was prepared according to the following steps: ① Weighing potato, black plum waste branch sawdust, mineral source potassium humate, peptone, soybean powder, potassium dihydrogen phosphate, magnesium sulfate, sucrose; ② Slicing potato, Mix black plum waste branch sawdust (crushed into 0.1-0.2cm particles) with mineral potassium humate, add 700ml of water, boil until boiling, keep boiling for 20 minutes, filter, remove residue, and keep the filtered juice; ③Weigh the well Add peptone, soybean powder, potassium dihydr...

[0061] Under the situation of embodiment 2 using liquid bacterial classification, the comparison test of the traditional culture medium of Pleurotus erodes and the culture medium of the present invention to fruiting bag mycelium growth rate, biotransformation rate, fruiting body quality

[0062] (1) The comparison between the fruiting culture medium C of the present invention and the culture medium that adds black plum discarded branch sawdust separately on mycelium growth and biotransformation rate

[0063] Medium formula 1 (recorded as training 1): 97% black plum discarded branch sawdust, 1.0% gypsum powder, 1.0% calcium superphosphate, 1.0% lime;

[0064] Medium formula 2 (denoted as training 2): 87% black plum discarded branch sawdust, 10% rice bran, 1.0% gypsum powder, 1.0% superphosphate, 1.0% lime;

[0065] The medium formula C of the present invention (recorded in this book): 54.0% black plum waste branch sawdust, 15.0% Paulownia waste leaf, 10.0% rice bran, 9.0% passi...

Embodiment 3

[0080] Embodiment 3 traditional liquid strain mycelial growth amount compares with the present invention's culture medium A mycelial growth amount

[0081] Traditional liquid culture medium formula 1 (denoted as biography 1): potato 20.0%, potassium dihydrogen phosphate 0.3% g, magnesium sulfate 0.15% g, sucrose 2.5%;

[0082] Traditional liquid culture medium formula 2 (denoted as biography 2): 20.0% of potato, 8.0% of corn flour, 0.3% of potassium dihydrogen phosphate, 0.15% of magnesium sulfate, 2.5% of sucrose, 1% of calcium percarbonate, gypsum Powder 1.0%;

[0083] Formula A of the liquid culture medium of the present invention (recorded as a book): 12.0% of Ma Ling potato, 10.0% of black plum discarded branch sawdust, 2.0% of mineral source potassium humate, 0.05% of peptone, 0.25% of soybean powder, and 0.3% of potassium dihydrogen phosphate %, magnesium sulfate 0.15%, sucrose 2.5.

[0084] With reference to Example 1, the liquid culture medium is prepared, and bottl...

Abstract

The invention discloses series culture mediums for increasing the yield of pleurotus edible fungi. The series culture mediums all take waste branch saw dust of black plum trees as main components. Theculture medium A is used for culturing a pleurotus geesteranus liquid strain, the culture medium B is used for culturing a pleurotus citrinopileatus and pleurotus ostreatus liquid strain, the culturemedium C is used for culturing in pleurotus geesteranus fruiting bags, the culture medium D is used for culturing in pleurotus citrinopileatus fruiting bags, and the culture medium E is used for culturing in pleurotus ostreatus fruiting bags. By applying the series culture mediums, the liquid strains of the pleurotus edible fungi including pleurotus geesteranus, pleurotus citrinopileatus and pleurotus ostreatus can be directly inoculated and cultured in the fruiting bags. It is proved through tests that the culture mediums and the method thereof have the advantages that an original culture composition with cottonseed hulls, mulberry twigs and corncobs as main components can be replaced, the yield of the pleurotus edible fungi can be increased, the quality of the pleurotus edible fungi canbe improved, the production period is shortened, and the production cost is lowered. In addition, the utilization rate of the waste branches of the black plum trees is increased, and resources are sufficiently used.

Description

technical field [0001] The invention belongs to the field of edible fungus cultivation, and in particular relates to a culture medium and a cultivation method for increasing the output of edible fungi of the genus Pleurotus. Background technique [0002] Pleurotus sajor-caju, Pleurotus otreatus, and Pleurotus citrinopileatus all belong to the Phylum Fungi, Class Basidiomycetes, Order Agaricaceae, and Pleurotaceae. Among them, Xiuzhen mushroom and Pleurotus ostreatus belong to the genus Pleurotus, and elm yellow mushroom belongs to the genus Pleurotus aureus. All three are rare edible fungus new species integrating edible, medicinal and therapeutic. Xiuzhen mushroom has a pleasing appearance, tender and crisp, and delicious taste. Fresh mushrooms are rich in protein (3.65-3.88%), and there are many types of amino acids. The mushroom also contains some physiologically active substances, which can induce the synthesis of interferon and improve human immunity. Function, also ha...
