T/HGSYJ 002-2024 Organic Fertilizer Production Technology Regulations for Mushroom Residue
Basic Information
Scope
Main Technical Content: 1. Key Techniques 1.1 Production Process of Organic Fertilizer from Mushroom Residue 1.2 Site Selection for Mushroom Residue Treatment The selection of the site for mushroom residue treatment should comply with the requirements of GB/T 34805. The site should be convenient for transportation, located at a higher altitude, and sheltered from the wind, and should be far away from drinking water protection areas, urban and rural residential areas, and edible fungi production sites. 1.3 Source of Mushroom Residue All kinds of cultivation by-products and discarded culture media generated after mushroom harvest can be used as sources of mushroom residue. 1.4 Pre-treatment of Mushroom Residue The pre-treatment of mushroom residue should comply with the requirements of GB/T 34805 and NY/T 3291. The plastic bags on the mushroom sticks are removed and then crushed and sieved to adjust the water content to 45–65% and pH 6.5–7.5. 1.5 Requirements for Microbial Strains The microbial strains used in the multi-functional compound microbial agent should be safe, effective, and have clear sources and names. The safety of the strains should comply with the requirements of GB 20287. 1.6 Primary Fermentation The mushroom residue is stacked into long strips 1.5–2 m wide and 0.8–1.2 m high. Water is added to control the water content of the mushroom residue at 50–65%, and natural fermentation is carried out for 20 days. After 10 days, the pile is turned over once. 1.7 Secondary Fermentation After the primary fermentation, the pile is turned over or subjected to forced ventilation to reduce the temperature to below 50°C. The water content of the mushroom residue is controlled at 35–45%. The mushroom residue is sprayed with a multi-functional compound microbial agent for secondary fermentation, and the pile is turned over once every 3 days. The secondary fermentation takes about 30 days, and the finished product should be blackish brown, o
