To successfully grow mushrooms during the hot season, it's essential to focus on three key technical aspects. These elements ensure optimal growth, high yield, and quality production even under challenging temperature conditions.
First, selecting the right high-temperature-resistant mushroom strains is crucial. Among the most suitable options are Xincheng 96 and Su Mushroom No.1. Xincheng 96 thrives in a wide temperature range of 18–36°C, with ideal germination temperatures between 25–33°C and fruiting temperatures of 20–36°C, peaking at 24–33°C. This strain is known for its resistance to heat, as the mushrooms remain fresh for up to 2–3 days without discoloration or opening of the caps. However, it has slower mycelium growth and lower decomposition efficiency, requiring higher-quality substrate. It's best planted in May–June and harvested from June–September. On the other hand, Su Mushroom No.1 has a broader germination range of 10–35°C, with an ideal germination temperature of 20–30°C and fruiting temperature of 10–35°C, peaking at 15–32°C. This variety grows faster, has strong vitality, and is ideal for planting in March–April with fruiting from April–July.
Second, proper composting and temperature management are vital. During the cooler months of February–March, choose a location with good base temperature and moisture retention, such as a plastic greenhouse using heap fermentation. The nutrient composition and composting method should be similar to those used for autumn mushroom cultivation. To maintain a stable internal temperature, use a warming agent during composting. By day five, the material should reach 60–65°C. After seven days, turn the pile when the temperature reaches 60°C, and continue turning every 5–6 days as the temperature drops. The compost is ready for inoculation when it turns dark brown, becomes soft, non-sticky, and has no foul odor.
Third, effective pest and disease control is essential. Common pests include mushroom flies, springtails, and aphids, while diseases like "walnut-like bacteria" can be problematic. A recommended approach is to mix 10 grams of Summer Mushroom Ning per 100 kg of culture material with 10 liters of water, then spray and mix into the bed before inoculation. Additional measures include:
1. **Pest Control**: After covering the soil, combine spraying with watering by mixing 1,000 times diluted mushroom insect net insecticide and seasoning agent. When temperatures exceed 20°C and adult mushroom flies appear, apply insecticides like cypermethrin to all areas around the bed to kill adults and reduce larvae.
2. **Disease Prevention**: Avoid using soil previously used for waste mushrooms. Instead, dig clean middle-layer soil from paddy fields, break it, and dry it before use. Spray a 500-times dilution solution 5 days after fruiting, and repeat after 5 days. If irregular bacterial patches appear on the soil surface, check the culture materials immediately. If discolored areas are found, remove the affected soil and culture material, and treat the area with a 300-times diluted solution. Allow it to dry naturally, then refill with water and resume mushroom cultivation after one week.
