Preparation process of harmless silkworm excrement fertilizer

According to the preparation process of the harmless silkworm excrement fertilizer, a customized enzyme formula is specially designed for silkworm excrement, and the enzymes can efficiently decompose cellulose and protein in the silkworm excrement under specific pH and temperature conditions, so that conversion of organic matters is accelerated. Meanwhile, the selected microbial strains not only survive vigorously in the silkworm excrement environment, but also effectively promote conversion of nutrient elements such as nitrogen and phosphorus, and the nutritional value of the fertilizer and the absorption efficiency of plants are further improved. The combination of the efficient enzyme and the specially selected microorganisms not only significantly shortens the treatment period, but also greatly improves the quality of the fertilizer. In addition, the method not only improves the efficiency, but also focuses on the sustainability of the environment, reduces the use of chemical additives, and is beneficial
