The site and method of mushroom production should be selected.

Bag cultivation of Pleurotus ostreatus in mushroom field can be carried out indoors or outdoors. Indoor mushroom production: generally, you can use spare houses to produce mushrooms, and you are required to choose rooms with good air permeability, good heat preservation and moisturizing properties, and sufficient light, preferably a room facing south. Outdoor mushroom production: generally, the above-ground or semi-underground plastic shed is used for mushroom production, especially the semi-underground plastic shed, because the semi-underground plastic shed has good heat preservation and moisturizing performance, which is conducive to the formation and growth of fruit bodies. The semi-underground plastic shed is generally 1 meter deep, 3.5 meters 4 meters wide and 8 meters 12 meters long. it is built with bamboo poles or wooden sticks, and the height of the shed can be managed by people walking upright. After the scaffolding is built, it is first covered with grass and then covered with plastic sheet. during the mushroom period, water can be sprayed on the grass to maintain humidity. In the shed, a bamboo pole with a diameter of 1.5 cm is used to build a shelf, which is high enough to hold 10-12 layers of bacteria bags. The whole shelf can be divided into 3-4 compartments, each can hold 3-4 layers of bacterial bags, and the distance between the two rows of shelves is 0.7-1 meters. In order to strengthen ventilation and ventilation, a drawer can be set up in the shed, and a shallow trench with a width of 15 cm and a depth of 10 cm can be dug between the two rows of shelves on both sides of the shed to discharge carbon dioxide from the shed.

The way to produce mushrooms: unlock the mouth of the bag and turn out or cut off the excess plastic film at both ends to expose all the mushrooms to the moist air to produce mushrooms. In order to maintain the humidity in the bacteria bag, it is generally used to produce mushrooms at both ends. Positioning mushroom production: the way of mushroom production at both ends is adopted, and the commercial quality of Pleurotus ostreatus is generally better. When the cultivation scale is large, we often choose to locate the mushroom, do not understand the mouth of the bag, and use thick needles to pierce holes in the bag to produce mushrooms.
