Covering soil is an important procedure for the cultivation of grass rot fungi such as mushrooms and Coprinus comatus. The following points should be noted in the specific operation:
Cover the soil in time: the soil covering material should be prepared after planting. The covering time is generally 15 to 20 days after sowing. When the hyphae have penetrated to 2/3 of the culture material, the hyphae spreading between the adjacent inoculation points has begun to connect, that is, the coarse soil is covered. In the coarse soil, the hyphae will come up and cover the fine soil.
The thickness of the covering soil should be moderate: the thickness of the entire covering layer is 2.5 to 3.5 cm.
The moisture content of the covering material is suitable: the water content of the covering material should be properly ensured during the whole process, so that it is completely wet and not sticky. If it is too dry, it needs to be humidified in time. If it is too wet, the hyphae will be slow or even degraded. rot.
Prevent pests in the soil covering material: When the soil covering material is pre-wet, 1000 times of fungicide mushroom or insecticide mushroom net or dichlorvos can be added to the water for disinfection of the pests and diseases. After disinfection, the piles are used for 5 to 7 days.
