Scope

Main Technical Content: 3. Terminology and Definitions The following terms and definitions apply to this document: 3.1 Fresh Corn Straw The aboveground parts (stems, leaves, and husks) of fresh corn grown in Qinggang County that remain after harvesting the corn cobs. 3.2 Organic Fertilizer Materials derived from plant and/or animal fermentation residues, used to provide plant nutrients through soil application. 3.3 Fermentation and Composting The process of stabilizing and rendering harmless organic materials such as fresh corn straw through biochemical conversion under microbial action. 4. Production Technology 4.1 Straw Collection 4.1.1 Collection Time The collection of fresh corn straw should be completed within one week after harvesting the corn cobs. If rain occurs during collection, the operation should be postponed until the weather clears. If low temperatures or frost occur, collection should be halted. 4.1.2 Collection Methods Collect fresh corn straw using mechanical or manual methods. During the operation, strict control of stubble height is required, maintaining it above 15 cm. Additionally, ensure that no impurities such as soil are mixed into the straw to avoid negatively affecting its quality. 4.1.3 Moisture Monitoring During straw collection, regularly monitor the straw's moisture content. The moisture content should be maintained between 60% and 75%, which is conducive to subsequent shredding, pulverization, and composting. If the moisture content exceeds 75%, the straw should be dried or mechanically dewatered until it meets the standard range. 4.2 Shredding and Pulverization 4.2.1 Shredding Requirements Use machinery or a straw cutter to shred the collected fresh corn straw into small pieces (2-5 cm long) to facilitate subsequent fermentation. 4.2.2 Pulverization Control The shredded straw should maintain an appropriate particle size to ensure effective decomposition during composting and improve the quali
