  • Detail

The output of Pleurotus ostreatus cultivated with waste paper has increased by 15% to 20%

under the current situation of rising prices of wheat bran, corn cob and other raw materials, some Pleurotus ostreatus cultivated with waste paper with low agricultural prices as the culture medium has been successful, and 800-1400kg of Pleurotus ostreatus can be produced per ton of waste paper

I. raw material ratio: waste paper 90%, wheat bran 6%, quicklime 1%, plant ash 3%

II. Raw material treatment: unpack the waste carton, expose it to the sun for 2-3 days, and then treat it into fragments of 8-10 square centimeters

III. disinfection and sterilization: put the treated waste box paper into the mixing tank, sprinkle wheat bran, plant ash and quicklime on the surface, pour boiling water with a temperature of 95 ℃ - 100 ℃, take out the material after fully mixing, and drain the water. It has the characteristics of wide measurement range, high precision and fast response, so that its water content can be reduced to 60%

IV. mixing strains: first put the cultivation material into the disinfected mixing pool, and then mix the strains crushed into the size of cotton seed shell into the cultivation material. The dosage of strains is 1.0%. Mix well and put it into a special plastic cultivation bag. In order to prevent contamination by miscellaneous bacteria, 0.1% carbendazim can be added while sowing because the experimental machine uses carbendazim in a humid environment

v. cultivation management: stack the inoculated cultivation bags indoors at 18 ℃ - 30 ℃, generally 4-5 layers are appropriate. After 20 days, if the mycelium in the bag is full, open one or both ends of the plastic bag, pay attention to light, strengthen air circulation, and spray water 1-2 times a day to keep the temperature of the bag at 15 ℃ - 20 ℃. After 7-8 days, Pleurotus ostreatus begins to grow, and then a batch of mushrooms can be harvested every 10 days

after harvest, inject 50 ml of 0.2% sugar solution and 50 ml of 0.1% potassium dihydrogen phosphate solution into the 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% - 20%
