Is it okay to cultivate Pleurotus ostreatus with distiller's grains?
The high yield methods of cultivating Pleurotus ostreatus and other edible fungi with fresh distiller's grains are as follows:
1. Fresh brewer's grains adjust ph 8-9 with lime, add 3% corn powder and appropriate amount of sawdust according to wet weight, and adjust about 65% of the culture material.
2. After weighing the dry white distiller's grains, add 15% corn powder, 4% lime powder and 130% water to build a pile for fermentation.
3. The effect of high yield can be obtained by inoculating bacteria with bag aerated material, two-stage full transformation cultivation by border soil cover film mushroom production method or conventional mushroom production management.
In order to make it easy for mushroom farmers to master, this paper focuses on the high-yield methods of cultivating Pleurotus ostreatus with fresh distiller's grains:
Culture material formula: 100 kg of fresh distiller's grains, 55 kg of sawdust, 12 kg of corn meal, 20 kg of cereal and grass section, 6.50 kg of urea, 1 kg of phosphate fertilizer and 3 kg of lime are the best formula.
Method of operation: ⑴ first add 2 kg of lime powder to the sawdust and then add fresh distiller's grains to mix well and pile up for 24 hours. ⑵ cereal grass section is about 3cm, soak in 1% lime water for 24 hours, make it fully soften, drain until the grass is not dripping by hand. ⑶ is then mixed with sawdust and lees, and urea and phosphate fertilizer are mixed 4 hours before bagging. Before bagging, the water content of the medium is 60% and the ph value is 8. ⑷ sterilization inoculation: use atmospheric pressure sterilization 100C, keep for 6 hours. When the temperature of the material was cooled to 25-28 ℃, the inoculation was carried out according to the aseptic operation method, and the bacteria were distributed in the culture room of 22 ℃. Generally, the mycelium grew into a bag in 18 days, and the mushrooms were produced in about 25 days, and were managed according to the routine method.

Cultivation of Pleurotus ostreatus in waste cartons
In the current situation of rising prices of raw materials such as wheat bran and corncob, Pleurotus ostreatus can be cultivated in waste cartons with abundant supplies and low prices, and each ton of waste cartons can produce 0.8 to 1.4 tons of Pleurotus ostreatus. Specific cultivation techniques are as follows: first, the ratio of raw materials: 90% of waste cartons, 6% of wheat bran, 1% of quicklime and 3% of plant ash. Second, raw material treatment: after the waste carton is taken apart and exposed to the sun for 2 to 3 days, it will be treated into pieces of 8~10cm2. Third, disinfection and sterilization: put the treated waste paper box into the mixing pool

Efficient cultivation of Pleurotus ostreatus with corncob
It is estimated that every 100 kilograms of corncob can produce 100-150 kilograms of fresh Pleurotus ostreatus, and the bioconversion rate is 150% 250%. Material selection and processing. Choose the fresh and mildew-free corncob and put it in the sun for 2-3 days and crush it to the size of corn kernels without sieving. Preparation of culture materials. Reference formula: corncob 79%, bean straw 15%, lime 4%, gypsum 1%, calcium superphosphate 1%, urea 0.3%. Preparation method: first dissolve lime and urea in water, then mix into the material, the ratio of water to material is 1 ∶ 1
