Studies On Fermented Material Culti-Vation Technology Of Pleurotus Os-treatus

Fermented material cultivation is the main approach to cultivatePleurotus ostreatus. To standardize fermented material cultivation of Pleurotusostreatus, we carried out the detailed study on the technology of fermented materialcultivation of the edible mushroom. The main results are as follows:1. Study on six kinds of bags of different standards revealed that when bags with astandard of20㎝×40㎝×0.0015㎝were used, time needed to bagful was the least,production cycle was the shortest, the contaminant rate was lowest, and the biologicalefficiency was the highest. Through the valuation of economic benefit, when bagswith standard of22㎝×45㎝×0.0015㎝were used, the econonic benefit was thehighest.2. Study on six inoculums of different sizes revealed that when the inoculum size was20%, time needed to bagful was the least, production cycle was the shortest, thecontaminant rate was the lowest and the biological efficiency was the highest.3. Study on three spawns of different sizes revealed that when particle spawn wasused(spawn size less than0.5㎝), time needed to bagful was the least, the producitoncycle was the shortest, the contaminant rate was the lowest and the biologicalefficiency was the highest.4. Study on layers of spawn revealed that when the number of spawn layers was five,the contaminant rate was the lowest, days needed to bagful were the least and thebiological efficiency was the highest.5. Study on five aeration ways revealed that when two holes were made, time neededto bagful was the least, the production cycle was the shortest and the biologicalefficiency was the highest.6. We established the protocol for fermented material technology of Pleurotusostreatus cultivation in autumn.
