Solar greenhouses have a 1–2 m rear slope with shaded space unsuitable for vegetables. Oyster mushrooms need only weak diffuse light and can grow there in winter. This uses otherwise idle space, while mushroom respiration supplies CO₂ that may support nearby vegetables and increase total greenhouse output.
1. Choose low-temperature strains, such as Annong 8601, Anda 02, Zili 539, Huanong 458 and Nongke No. 2. Their optimal fruiting temperature is 10–18°C.
2. Sowing time: sow from late November to late December for fresh mushrooms around the Spring Festival.
3. Sun-dry fresh cottonseed hulls for 2–3 days. Wet and mix at a dry hull-to-water ratio of 1:1.2, then heap for two hours to absorb water and reach about 60% moisture.
4. Use polyethylene film tubes 0.03–0.05 mm thick and 25–30 cm in diameter, cut into 45–50 cm bags. Fill each with about 1.5 kg dry-equivalent substrate. Fold 6–8 cm at one end, point it down, fill halfway and add a spawn layer; continue filling, add another layer 6–8 cm below the opening and tie the bag securely.
5. Stack inoculated bags in the greenhouse in 2–4 rows, depending on space, 8–10 layers high. Leave 50 cm passages between stacks and behind them for airflow and work. Hang silver-gray reflective film between central posts to prevent direct sun on the rear area while improving light for vegetables.
6. During colonization, turn stacked bags every 5–7 days for even temperatures and uniform growth. Keep substrate at 15–25°C and air humidity near 60%.
7. Fruiting usually begins near day 40. When primordia appear at the bag ends, open both ends for ventilation, mist 1–2 times daily, and maintain air humidity near 90% and substrate temperature at 10–20°C.
8. Harvest promptly when cap edges become wavy and the stem junction becomes depressed. Mist lightly beforehand. Remove dead mushrooms, dip bags in water briefly, drain and restack for the next flush. Generally expect 3–4 flushes.
