Cultivation techniques of Pleurotus ostreatus

The cultivation of Xiuzhen mushroom should first select a good cultivation place, preferably in a well-ventilated and clean area; secondly, fumigate the mushroom room before cultivation, and make pre-wet treatment; after the cultivation bag is installed, put it on the bedstead, pay attention to ventilation and moisturizing; mushroom collection can be carried out after mushroom production.

Several commonly used formulas in the cultivation of Pleurotus ostreatus:

Formula one: sawdust 60%, cottonseed shell 15%, rice straw 15%, wheat bran 10%.

Formula 2: sawdust 80%, wheat bran 18%, gypsum 1%, sucrose 1%.

Formula 3: sawdust 59%, cottonseed shell 30%, wheat bran 10%, gypsum 1%.

Formula 4: sawdust 30%, cottonseed hull 30%, rice straw 30%, wheat bran 10%.

Sawdust must be sifted first to remove wood blocks and wood chips to prevent puncturing plastic bags. The straw is cut into 3-4 cm long by a special machine and soaked in PH11 lime water for 48 hours. Remove it and rinse with water to make the PH rise to about 7, then drain the excess water. Cottonseed hulls and bran should be set aside after exposure to the sun for a day. Formula 4 has a lower C _ hand N and a higher requirement of asepsis during inoculation.

The preparation method is as follows: sieving the mulberry wood chips, removing impurities and building a pile; sprinkling the sawdust surface with raw lime powder and covering the film to increase the temperature; weighing other raw materials and stirring the mulberry sawdust, holding the culture material in a plastic bag; sterilizing after bagging, then inoculating, and then putting it back into the indoor bacteria culture, entering the mushroom stage when the mycelium grows in the whole bag; the color of the fungus cap becomes lighter, and the spore bullet is picked before shooting.

In addition, the humidity range of mycelial growth of Pleurotus ostreatus is 10-35 ℃, which is the most suitable for temperature rise of 25-27 ℃. Therefore, in the process of cultivating Xiuzhen mushrooms, the control of temperature is also very important, we must pay attention to it.
