A Detailed Guide to the Cultivation Techniques and Management Methods of the Oyster Mushroom (Pleurotus geesteranus)
For cultivating the oyster mushroom, first select a good cultivation site, preferably a well-ventilated and clean area; next, before cultivation, fumigate and disinfect the mushroom house and carry out pre-wetting treatment; after the cultivation bags are filled, place them on the bed racks, paying attention to ventilation and moisture retention; once fruiting begins, the mushrooms can be harvested.
Several commonly used formulas in the oyster mushroom cultivation process:
Formula One: sawdust 60%, cottonseed hulls 15%, rice straw 15%, wheat bran 10%.
Formula Two: sawdust 80%, wheat bran 18%, gypsum 1%, sucrose 1%.
Formula Three: sawdust 59%, cottonseed hulls 30%, wheat bran 10%, gypsum 1%.
Formula Four: sawdust 30%, cottonseed hulls 30%, rice straw 30%, wheat bran 10%.
The sawdust must first be sieved to remove wood chunks and wood chips and prevent them from piercing the plastic bags. The rice straw is cut into 3-4 cm lengths with a special machine and soaked in lime water at pH 11 for 48 hours, then removed, rinsed with water to bring the pH down to about 7, and then drained of excess water. The cottonseed hulls and wheat bran are best sun-dried for one day before use. Formula Four has a relatively low C/N ratio, so the sterility requirements at inoculation are higher.
The preparation method is: sieve the mulberry sawdust, remove impurities, and pile it up; sprinkle quicklime powder on the surface of the sawdust and cover with plastic film to raise the temperature; weigh the other raw materials and mix them with the mulberry sawdust, and place the culture material in plastic bags; after bagging, sterilize, then inoculate, and put back indoors for mycelial incubation; when the mycelium has grown throughout the entire bag, it enters the fruiting stage; harvest before the cap color fades and before spores are discharged.
In addition, the humidity range for the mycelial growth of the oyster mushroom is 10-35°C, and the most suitable growth temperature is 25-27°C. Therefore, in the process of cultivating the oyster mushroom, temperature control is also very important, and everyone must pay close attention to it.
