Detailed Explanation of Key Points for High-Yield Oyster Mushroom Cultivation Techniques

High-yield oyster mushroom cultivation techniques mainly focus on three points: selecting excellent strains, reasonably supplying nutrient elements, and controlling temperature and humidity well. The yield standard for high-yield oyster mushroom cultivation is more than 2 kg of fresh mushrooms per 1 kg of raw material.

1. Select excellent strains

The requirements are a wide fruiting temperature range, stable and high yield, attractive mushroom shape, short stipe and thick cap, bright color, and unique flavor, with both contamination resistance and degeneration resistance. Therefore, when introducing strains, strict assessment must be carried out and fruiting trials must be done well. Strains such as Guoping No. 1, Guoping No. 2, Qingfeng No. 1, and Sanxia No. 1 all possess the above characteristics and can be called outstanding new varieties among oyster mushrooms.

2. Control temperature and humidity well

The temperature requirements of the mycelium and fruiting body differ at different growth and development stages. The fruiting temperature varies significantly among strains of different temperature types, and the temperature differs markedly among different production seasons. In production, we must proceed from reality. During the mycelial growth period, the substrate moisture content is 65%. During the fruiting period, the moisture content reaches 68%-70%. When the relative air humidity is maintained at 85%-95%, the mushrooms grown are large and thick, with bright color and good quality.

3. Reasonable supply of nutrient elements

In production, the quality of the main raw materials must be excellent. The various substances selected must be fresh, dry, free from mildew and deterioration, and free from insect damage. Any raw materials that have already been soaked by rain and have become mildewed and deteriorated are not suitable as culture materials. Even if successful, it is difficult to achieve high yield.
