Planting techniques of Pleurotus ostreatus

Xiuzhen Pleurotus ostreatus, also known as Pleurotus ostreatus and Pleurotus ostreatus, as its name, is small in size, graceful in posture, crisp and tender in texture, delicious in taste and unique in taste. it is a nutritious food with high protein and low fat, as well as the laudatory name of "monosodium glutamate mushroom". Let's take a look at its planting techniques.

1. Preparation of breeding materials

Xiuzhen mushroom generally uses sawdust, rice straw, cottonseed hull and other raw materials to make culture materials, according to practical production. Using the formula of Lentinus edodes to cultivate, although it can achieve high yield, but the cultivation time is too long and the cultivation cost is high, so using sawdust and straw instead can also achieve high yield and shorten some cultivation time. Here are one or two common ingredients: (1) sawdust 60%, cottonseed hull 15%, rice straw 15%, wheat bran 10%; (2) sawdust 30%, cottonseed hull 30%, rice straw 30%, wheat bran 10%.

2. Bag sterilization

After the culture material is prepared with the formula, it can be bagged with a special edible fungus cultivation bag, if the dry material is bagged 250-350 grams, and if it is wet, 500-600 grams. After bagging, seal the mouth of the bag, ready to start high temperature sterilization, generally use steam sterilization method, require 0.103 MPA, temperature at 121 degrees, sterilization in this environment for 2 hours, and if sterilization under atmospheric pressure should be kept for 12-24 hours, unload the bag after sterilization to dissipate heat.

3. Inoculation of bacteria

After sterilization, the bacteria can be inoculated, and in a professional inoculation room, a darker and aseptic environment is required, and the entry personnel should be disinfected and sterilized so as not to cause vaccination failure. After inoculation, it can be transferred to the culture room for germ culture, and the temperature should be kept between 24-26 degrees in the first three days, so that the bacteria can be colonized and cultured in the culture material. After the fourth day, the hyphae grow in the bacteria bag, and the metabolism will generate heat. So at this time, the temperature of the culture room should be reduced by 2-3 degrees. Mycelium growth and development do not need any light, so the culture room is in a relatively dark environment, it is necessary to strengthen ventilation to increase oxygen, so as to avoid high carbon dioxide concentration, resulting in mycelium hypoxia. To keep the humidity between 60% and 70%, it is necessary to strengthen ventilation and reduce humidity if it is too high, and if it is too low, it can be humidified by spraying water mist. Generally, about 25-35 days after inoculation, the hyphae will cover the whole bacterial bag, and the mushroom production management can be carried out at this time.

4. Mushroom production management

After the mycelium grows and matures, the bacterial bag can be moved into the shed for cultivation, and when placed, the upper shelf row bag or flat wall overlap, open the mouth of the bag and let oxygen into the bag. At the same time, cover the film during the day, uncover the film at night, in this way, artificially increase the temperature difference between day and night by about 10 degrees to stimulate growth, and then through bright light to promote the formation of fruiting bodies. During the mushroom production period, the temperature had better be controlled between 18 and 22 degrees Celsius. If the temperature is high, the temperature should be cooled and the low temperature should be heated up. At the same time, the humidity of the shed should be kept between 85 and 95%, so that the mushroom can be safely produced.
