Embodiment Construction

[0011] The method for producing Pleurotus ostreatus strains with disposable birch chopsticks is divided into four steps: pretreatment of chopsticks, preparation of chopstick culture medium, inoculation and culture, and transfer of strains. (1) Chopsticks pretreatment Remove bent and cracked defective products from disposable birch chopsticks, sharpen the forks of the chopsticks, immerse them in 5% lime water for 20-24 hours, then immerse the chopsticks in clean water, pass through 1500mg / h ozone for 30-60 minutes; (2) Preparation of chopsticks culture medium Immerse the pretreated chopsticks in 5.5% sucrose, 1.9 glucose, 0.12% V B1 , 0.08% of V B9 , 0.2% potassium dihydrogen phosphate, and 0.2% magnesium sulfate aqueous solution, the water temperature is kept at 50-70 ° C, after soaking for 1-2 hours, remove and drain the water, and when the surface is slightly dry, put 50% In the mixture of bran and 50% corn flour, stir evenly, so that the chopsticks are covered with the mi...

Abstract

The invention discloses a method for producing oyster mushroom strains from birch chopsticks. The method comprises four steps of: performing pretreatment on the chopsticks, preparing a culture medium for the chopsticks, performing inoculation culture and transferring the strains. According to the method disclosed by the invention, by carrying out pretreatment on the birch chopsticks, on the one hand, harmful substances in the birch chopsticks can be fully decomposed, and on the other hand, convenience is brought to the insertion of the birch chopsticks into a mycelium mass during the inoculation. When a culture medium for the birch chopsticks is prepared, as birch contains a large number of nutrient components required for growth of oyster mushrooms, only sucrose, a compound fertilizer, wheat bran and corn flour need to be further added, therefore the components in a nutrient solution are greatly simplified and the preparation process is also trouble-saving and effort-saving. When the inoculation is performed, only the chopsticks need to be directly inserted into the mycelium mass for completion, the operation process is convenient, fast, effort-saving and labor-saving and the pollution rate is very low. Mycelia are fully grown all over the whole chopstick strains after culture, the cell ages after the inoculation are short and consistent, the strains are fast in growth speed, the mycelia are robust, and the strains are high in purity and strong in resistance to other fungi. The method disclosed by the invention further has the more prominent advantages of low production cost and very significant economic benefits.

Description

technical field [0001] The invention relates to the preparation technology of Pleurotus ostreatus strains, in particular to a method for preparing secondary and tertiary species of Pleurotus ostreatus using disposable birch chopsticks as main raw materials. Background technique [0002] At present, the secondary and tertiary species of bagged oyster mushrooms are mainly granular strains, such as sawdust strains, grain strains, and corncob strains. Granular strains have stable properties and strong resistance to impurities, but there are complex inoculation procedures, low inoculation efficiency, labor and time-consuming, high production costs, large land occupation, and long cultivation cycles. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the invention provides a method for producing Pleurotus ostreatus strains with birch wood chopsticks, which is strong in anti-miscellaneous ability, rapid in germination and easy to use.
