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 rich and low-cost waste cartons. Pleurotus ostreatus can produce 0.8-1.4 tons per ton of waste cartons. The specific cultivation techniques are as follows:
First, the ratio of raw materials: waste carton 90%, wheat bran 6%, quicklime 1%, plant ash 3%.
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, sprinkle wheat bran, plant ash and quicklime on the surface, pour 95 ℃ ~ 100 ℃ boiling water, stir well, take out, and drain water to reduce its water content to about 60% (hold the material with your hand and see water droplets between your fingers).
Fourth, mix in the bacteria: first put the cultivation material into the sterilized mixing pool, and then mix the cultivation species crushed into the size of cottonseed shell into the cultivation material, the appropriate amount of bacteria is 10%, mix well and put it into a special plastic cultivation bag. In order to prevent miscellaneous bacteria pollution, 0.1% carbendazim fungicide pesticide can be added while seed dressing.
Fifth, cultivation management: the inoculated cultivation material bags should be stacked in the room with a temperature of 18: 30 ℃, usually 4-5 floors. After 15-20 days, if the mycelium in the bag is full, open one or both ends of the plastic bag, pay attention to the light, strengthen the air circulation, spray water once or twice a day, keep the bag temperature at 15-20 ℃, about 7-8 days, Pleurotus ostreatus begins to grow, and then a batch can be harvested every 10 days or so. After each batch is finished, 50ml 0.2% white sugar and 50ml 0.1% potassium dihydrogen phosphate are injected into each plastic bag with a syringe. With this method, one or two more batches of mushrooms can be harvested, and the yield can be increased by 15% and 20%.

How to continuously cultivate Pleurotus ostreatus with good quality and high yield
In some old mushroom areas where Pleurotus ostreatus is continuously cultivated, destructive diseases such as walnut disease and button disease often occur. If it is light, the yield will be reduced by 50%, and if it is heavy, there will be no harvest, which will bring certain economic losses to farmers. Therefore, it is very important to change the traditional cultivation techniques. The main results were as follows: (1) the disease-resistant varieties were selected and compared, Heiping and Xide 99 were selected, followed by Jiangdu 5526 and Xinyi 1. 2 the recommended formula for preparing high yield medium is as follows: 75% of cottonseed shell, 15% of corncob, 7% of wheat bran, 3% of quicklime and 0.50 of diammonium phosphate.

Is it okay to cultivate Pleurotus ostreatus with distiller's grains?
The high-yield methods of cultivating Pleurotus ostreatus and other edible fungi by using fresh distiller's grains are as follows: 1. Fresh brewer's grains adjust ph 8-9 with lime, add 3% of corn mixed 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, the key points here
