[0002] my country is a major agricultural country with a vast supply of crop straw. Annually, approximately 1 billion tons of straw resources are generated, with over 800 million tons available for collection. Utilizing straw as fertilizer is one of the primary technologies for its comprehensive utilization. Farmers in southern regions like Yunnan are accustomed to using simple composting techniques in the fields. This involves mixing straw, human feces, animal excrement, weeds, and other organic waste, piling them together, sealing them with a paste, and then using microbial fermentation under natural conditions to mature the organic matter in the pile to a stable level acceptable to the soil, forming a nitrogen-rich humus. This process requires little or no human control. Following technical improvements by the agricultural and rural authorities, field composting tanks have been gradually promoted. In recent years, these have been upgraded to farmland straw composting machines. While most of these machines feature a stirring mechanism to accelerate fermentation, resulting in high fermentation efficiency, their tanks are often fixed, making it difficult to remove the fermented organic fertilizer.
