Matters Needing Attention in the Use of Groove Type Compost Turner
It mainly includes the control of raw material composition, selection and use of microbial agents, aeration and oxygenation during fermentation. ① The raw materials include livestock manure, sawdust, crop straw and other raw materials, which are mixed to adjust the carbon nitrogen ratio. In addition, calcium phosphate, zeolite , raw soil and other substances are added to absorb the odor generated in the fermentation process. ② the selection of appropriate microbial fermentation agent can shorten the fermentation time. ③ oxygen control in the fermentation process to ensure aerobic fermentation. This composting fermentation method requires that the moisture content of livestock manure should be kept at a low level (below 70%). Therefore, it requires that the cleaning and transportation mode of livestock manure should be dry cleaning, or the solid-liquid separation conditions of wastewater should be provided, and the solid fertilizer should be treated in this way.
