Sludge-based disease-resistant seedling raising substrate production method

The invention relates to a sludge-based disease-resistant seedling raising substrate production method. The method is characterized by comprising the following steps: uniformly mixing waste materialssuch as mushroom residue particles, agricultural straw crushed substances and sawdust powder with fly ash, sludge and biological control microbial inoculum to obtain a product P1; performing aerobicfermentation on the product P1, and turning and throwing the product P1 every 7 days by a turning and throwing machine to obtain a product P2; sieving a product P3, returning oversize to step S4 for mixing, compounding throughs with perlite, vermiculite, coconut shell silk and trace elements to obtain a matrix P, and adjusting pH and EC of the matrix P to obtain a seedling raising matrix finishedproduct. The invention provides the sludge-based disease-resistant seedling raising substrate production method. Sludge and agricultural waste are used as raw materials, the disease-resistant seedlingraising substrate is produce
