A Detailed Guide to White Mushroom Cultivation Techniques: Master the Key Points of Cultivation and Management
Cultivating white mushrooms requires building mushroom sheds, managing the sheds, preparing raw material formulas and ratios, selecting suitable varieties, and promptly adjusting environmental conditions after sowing. White mushrooms have high environmental temperature requirements; after sowing is completed, clean up the surrounding sanitation and ventilate promptly to prevent pests and diseases.
Post-Sowing Management of White Mushrooms
1. First spread a 3 cm thick layer of fresh wheat straw on the mushroom beds in the shed, then evenly spread the fermented compost onto the beds. Then fumigate and disinfect with potassium permanganate plus formaldehyde, and after 24 hours open the doors and windows to ventilate and exchange the air. When the compost temperature drops below 28°C, sowing can begin, using one bottle of spawn per sq m in 500 ml bottles. Evenly scatter the spawn on the surface of the compost, gently press and level it so that the spawn sinks about 2 cm into the compost.
2. Within 3 days after sowing, keep the doors and windows properly closed and maintain air humidity at around 80% to promote spawn germination. About 15 days after sowing, when the mycelium has basically grown throughout the compost layer, apply the casing soil.
Casing soil method: choose soil with good water absorption, a granular structure, many pores, that is not sticky when wet and does not crumble when dry. First mix in lime powder, then saturate the soil with an aqueous formaldehyde solution, and apply the casing when it does not stick to the hand, forms a ball when grasped, and breaks apart when dropped.
3. After casing, regulate moisture so that the water content of the soil layer stays at around 20%. After casing, the air humidity should remain at 80%-90%, and the temperature at 13-20°C (optimal temperature 15-18°C). Water should be sprayed at appropriate times depending on whether the soil layer is dry or moist; strictly controlling temperature and humidity is the key to high quality and high yield of button mushrooms.
