Multiplication circulating reproduction method for oyster mushroom and pleurotus geesteranus strains

Abstract

The invention relates to the new technical field of preparation of edible fungus strains, in particular to a multiplication circulating reproduction method for oyster mushroom and pleurotus geesteranus strains. The multiplication circulating reproduction method comprises arranging strain culture rooms with cross-ventilation windows, shades and space of about 40-50 m3 per room, establishing a strain culture bed frame with a multilayer structure in each culture room, performing strain multiplication circulating culture in the bed frame, and matching an interval timer during the culture period to control an air pump to supply oxygen to the strains intermittently so as to facilitate rapid germination and feeding of hyphae; and forming producing culture matrix materials by fermentation, mixing the producing culture matrix materials and the strains during reproduction according to weight ratio, culturing the mixture on the culture bed frame to obtain a first batch of strains, then mixing the first batch of strains and the producing culture matrix materials according to weight ratio, obtaining a second batch of strains by managing culture, and performing circulating multiplication reproduction on the second batch of strains according to the method so as to cultivate the strains with the amount suitable for enough self-arrangement.

Description

technical field [0001] The invention relates to the field of a new technology for the preparation of edible fungus strains, in particular to a method for multiplying and cyclically multiplying the strains of Pleurotus ostreatus and Pleurotus ostreatus. technical background [0002] The traditional production of Pleurotus ostreatus and Pleurotus ostreatus mostly adopts clinker production, and the process is: test tube parent species → original species → cultivated species, and then the cultivated species are transferred to the production of mature materials through normal pressure sterilization in large quantities. in the base material, and then managed until fruiting by culturing until the mycelium is overgrown with the base material. From the preparation of original seeds to the production of mushrooms, the production cycle takes 3 to 4 months; the production cycle is not only long, but also very cumbersome in operation procedures, especially cooking large quantities of pro...

Problems solved by technology

From the preparation of original seeds to the production of mushrooms, the production cycle takes 3 to 4 months; the production cycle is not only long, but also very cumbersome in operation procedures, especially cooking large quantities of production medium materials requires nearly 20 hours of killing Bacteria, time-consuming and laborious, and consume a lot of energy, resulting in rising production costs
