Bag planting method of volvariella volvacea

The main results are as follows: (1) the dry and mildew-free straw is selected and soaked in a 5% lime pool for 10-12 hours. When soaking the straw, attention should be paid to compacting the straw, and the lime water in the pool can completely submerge the straw.

2 cut the straw that has been soaked and picked up, drip dry the straw with remaining moisture, and cut it into grass sections about 20cm long with a straw cutter or guillotine. Pay attention to the fact that it is too long to bag, too short, too much work, and is not conducive to mycelium kink.

3Culture medium formula: 50kg of rice straw, 7.5-10kg of rice bran, 1-1.5kg of peanut, 1kg of phosphate fertilizer, 1kg of gypsum powder, 0.15-0.25 kg of potassium dihydrogen phosphate; 35kg of rice straw, 5kg of rice bran (wheat husk), 1.5kg of corn meal, 15kg of cottonseed hull, 1.5kg of gypsum powder, 1kg of compound fertilizer; 50kg of rice straw, 5kg of grain powder, 1.5kg of peanut wilt, 1kg of gypsum powder, 1kg of phosphate fertilizer. All raw materials in the formula should be dry, no mildew, no impurities, peanuts withered require crushing before use.

(4) mix the other raw materials in the formula first, and finally sprinkle the mixed raw materials evenly on the straw. after mixing several times, you can pack the bags.

.5 to grow volvariella volvacea in bags, low-pressure polyethylene bag film is generally selected, and the specification is 50cm × 24cm × 0.0035cm (or 0.004cm) bags. In order to reduce the production cost, 56cm × 30cm × 0.005cm bags can also be used. It is required to be strong when loading. To the extent that it won't break the bag. After installation, the two ends are fastened with plastic packing tape.

6Disinfection and sterilization the packed materials were sterilized in time, and the sterilization time was 100 ℃ for 8-12 h. And require the same day to pack the material, the same day to sterilize the bacteria, beware of acid deterioration.

(7) the material bag after inoculation and sterilization can be inoculated after cooling to less than 40 ℃. Unlock the material bag during inoculation, carry out open inoculation, and spread the bacteria evenly at both ends of the bag. 10-12 bags are suitable for each bottle of bacteria.

.8 the mushroom canister of good seed should be arranged and stacked, and the temperature of the pile should not exceed 40 ℃. Beware of the end of harvest caused by burning pile. Under normal circumstances, the bacteria can be sent out in about 10 days.

9 mushroom management will be good bacteria mushroom bag, take off the bag to produce mushroom, the method is to empty the bag, build into a 4-5 layer high bacterial wall, cover with film, should be ventilated several times a day, keep the air relative humidity at about 90%, and reduce the temperature difference to less than 5 ℃ as much as possible.

10 timely harvest is an important measure to increase the yield of volvariella volvacea. The cover of volvariella volvacea is oval, and the harvest is the best before the coating is broken through. When harvesting, hold down the culture material of the growing part of the mushroom body with one hand, grasp the base of the mushroom body with the other, gently twist it in clusters with large bands and small ones, and do not hurt the immature buds. The harvested straw mushrooms use a knife to eliminate the rotten grass and sundries at the base, and then grade or process them.
