Four skills of Pleurotus ostreatus bag ventilation
Bag cultivation of Pleurotus ostreatus has the advantages of low cost, high benefit and convenient management, but the direct use of rope in bag cultivation often causes poor ventilation, affects bacteria, causes pollution, and even leads to cultivation failure. Here are several ventilation techniques:
One is the ventilation plug method. Wheat straw, cotton wool and so on are used as materials and stuck at both ends of the bacterial bag to form a ventilation plug. The size of the plug depends on the size of the bacterial bag, large bags with large plugs, small bags with small plugs; also depends on the germ temperature, when the germ temperature is low, the plug can be smaller, and vice versa.
The second is the ring method. Can buy horn mouth ring, wrap the bag with cotton plug, if you can't buy the horn mouth ring, you can also make it with plastic packing tape (cut into segments and welded with soldering iron), seal with Kraft paper and rubber band for external use. Note that the ring should be firmly fastened to prevent the test from falling off.
The third is the ventilation hole method. Use a sewing machine needle to pierce a row of holes 6 cm from the bag, about 1 cm apart. Just sow the bacteria in the hole when loading. Do not pierce too many holes, and be careful not to operate the bacterial bag when piercing the hole, otherwise the bacterial bag is easy to crack in the process of loading.
The fourth is the method of ventilation hole. With a tapered stick with a thumb thick, make 3 6 cm deep holes in a triangle at both ends of the bag, then drill a hole horizontally in the middle sowing place, and place the bag into a sterilized indoor germ. The action of drilling should be light, not too hard.

What to do when the lid of Pleurotus ostreatus grows pimples?
This kind of situation generally occurs in winter, the upper part of the cap, especially the edge, is covered with pimples of different sizes, and when it is serious, the whole cap is covered with bumps. After forming a pimple, the fruiting body grows very slowly. The disease affects the quality and output of goods. The main reasons for pimples are as follows: (1) raise the temperature of indoor fire and form carbon dioxide accumulation. (2) the culture bag was close to the tuyere, and cold wind stimulation caused the imbalance of cell growth inside and outside the lid of Pleurotus ostreatus. Prevention and treatment: strengthen ventilation and get rid of all the bumps.

High yield of Pleurotus ostreatus covered with stick soil
Bagged inoculation: fresh cottonseed shell was added with 1% gypsum, 1% lime and 0.10% carbendazim, and the ratio of material to water was 1: 1.3: 1: 1.5. Mix well, accumulate and ferment on the cement floor for 5 days, then bag it. When bagging, fasten one end of the canister firmly, fill it with a few bacteria, and then when loading to half of the bag, sow 6 red jujube-sized bacteria on the edge of the material, then continue to fill the bag, sprinkle a layer of bacteria on the surface of the bag, and fasten the mouth of the bag. Sending bacteria in a row bag: the side of a bag to send bacteria.
