The latest course on cultivation techniques and methods of bagged Pleurotus ostreatus

Pleurotus ostreatus is a widely cultivated edible fungus, which belongs to Pleurotus ostreatus of Pleurotus ostreatus, basidiomycetes, Pleurotus ostreatus, basidiospores, rich nutrients, let's take a look at the cultivation technology of bagged Pleurotus ostreatus.

Advantages of bag planting

Bagged Pleurotus ostreatus is beneficial to control the harm of miscellaneous bacteria and pests, has a high success rate, can make full use of space, and occupies a small area (1500-2000 bags can be cultivated in a culture room of 15-18 square meters). Moreover, the production cycle is shortened, the accumulation of bacteria is used to increase the temperature of the material, speed up the occurrence of bacteria and shorten the mycelial growth period. At the same time, it is convenient for mobile management, can make full use of the site, helps to control temperature, maintain humidity, produce mushrooms neatly, good shape and stable yield.

Culture material formula

There are many sources of Pleurotus ostreatus culture materials, such as cotton husk, sawdust, rice straw, leaves, and other crops and vegetable stalks can be used to cultivate Pleurotus ostreatus, usually cotton husk and rice straw as the main materials. ① formula 1: cotton husk 98%, lime 1%, gypsum powder 1% PH 6.5. ② formula 2: cotton husk 60%, rice straw powder 33%, lime powder 1%, gypsum powder 1%, PH 6.5. ③ formula 3: Rice straw powder 80%, corn meal or rice bran 18%, calcium superphosphate 1%, lime powder 1%, PH 6.5.

Mixing method

After weighing the raw materials and drugs according to the formula, place them in a clean room or on an open space, add water according to the dry material water for 1. 3 to 1.8, and mix well with nail palladium or shovel. After mixing, the culture material is squeezed by hand, and if there is water exudating between the fingers but not dripping, it shows that the water content is appropriate.

Bagging sterilization

The plastic bag is made of low-pressure polyethylene tube film with a width of 22cm and 25cm, cut into a plastic cylinder of about 40cm and 50cm, put the prepared culture material into the plastic cylinder, press it, put the plastic neck ring or fiber band ring on both ends, turn the plastic tube mouth down, move in from the side near the center along the outside of the ring, cover the ring with Kraft paper or newspaper, and hoop it with a rubber band. Put the material bag into a big soil steamer to cook and disinfect, put several bags together, and wait for the atmosphere (100 ℃) to maintain for 8 hours.
