Cultivation techniques of Pleurotus ostreatus fermentation material

Pleurotus ostreatus is one of the common mushrooms, which is rich in nutrients, and most mushrooms need fermented materials to be cultivated. So, what is the cultivation technology of Pleurotus ostreatus fermentation material?

First, build a mushroom shed

The existing vacant houses and basements can be transformed into mushroom houses, or new mushroom houses can be built. Mushroom houses should be disinfected before use to reduce bacterial pollution and insect pests.

Second, the allocation of nutrients

You can choose one of sawdust, cottonseed hull, waste cotton, rice straw, bagasse, corncob, corn straw, peanut shell, bean stalk powder as raw materials, and then add appropriate amount of wheat bran, rice bran, gypsum, superphosphate and other auxiliary materials. 85 kg of corncob, 10 kg of wheat bran, 5 kg of corn flour, 5 kg of mushroom Dazhuang 5 Mel 6 bags, 1 kg of compound fertilizer, 3 kg of lime and 0.2% of carbendazim were configured.

Third, mix materials and pack bags

Mix the nourishment and water, and then pile it up for 18 hours, which can make the nourishment mature. Mix the ingredients and ferment for several days, then sterilize with high temperature. Then pack the bag, press it with your fingers while loading it by hand, press the bag wall around, press slightly in the center, loose in the middle, and loose in the middle at both ends. After bagging, put it on the rack in the pot for sterilization, the temperature is 100℃, the time is 8: 10 hours, when the temperature drops to 80 ℃, take out and move into the mushroom room.

IV. Inoculation of bacteria

Do not vaccinate until the temperature in the bag drops to 30 ℃. Disinfect your hands, inoculation tools, plastic bags and mushroom room before inoculation. During the inoculation, one person opened the mouth of the bag, and one person quickly dug out the bacteria into the bag, fastened the mouth of the bag and connected it to the other end. After the completion of the inoculation, roll the cultivation bag on the lime powder once and let the lime powder fill the holes in the bag to prevent contamination by miscellaneous bacteria.

5. Mushroom house management

Two days after planting, the material temperature should be controlled below 30 ℃ and the room temperature should be controlled below 15 ℃. After 10 days, the mycelium grew all over the material, the room temperature could be increased to 20 ℃ 25 min, and the mycelium grew all over the culture material in 30 days. After mushroom emergence, the indoor temperature can be maintained at 15 ℃ 18 min, ventilated for 1 hour at the lowest temperature, and water sprayed according to humidity. In the peak period and late stage of mushroom production, the nutrients in the culture material are exhausted, so fertilizer should be applied in time.

In the process of cultivation, careful management should be carried out according to the characteristics of each growth stage of Pleurotus ostreatus, so as to avoid the occurrence of the above factors that do not produce mushrooms or abnormal mushroom production, so as to obtain stable and high yield.
