变废为宝，点“叶”成金！看怀集如何玩转农业生态经济学

Core Viewpoint - The article discusses how Huai Ji County is transforming agricultural waste, specifically sugarcane leaves, into valuable resources through innovative ecological economic practices, thereby promoting sustainable agricultural development [1]. Group 1: Agricultural Innovation - Huai Ji County Dongsheng Agricultural Technology Co., Ltd. was established in 2024 and has integrated fallow land for large-scale cultivation of quality sugarcane varieties "Yue Tang 159" and "Liu Cheng 136," with a planting area reaching 3,500 acres [11][12]. - The first harvest season yielded an average wet weight of 7.5 tons per acre, with a total output exceeding 26,000 tons [14][15]. Group 2: Waste Management Challenges - The company faced a challenge with over 8,500 tons of sugarcane leaves generated, which were previously burned or discarded, leading to environmental pollution and resource wastage [15][16]. - Traditional burning methods do not meet environmental standards, and the accumulation of waste affects future farming [17][18]. Group 3: Government Support and Collaboration - The Huai Ji County Agricultural Technology Promotion Center is implementing projects for comprehensive utilization of agricultural straw and green cyclical agriculture to meet "dual carbon" goals, supported by national policies and central financial resources [24][25][30]. - The government facilitated collaboration between Dongsheng Agricultural and Guangdong Di Sheng Ecological Agricultural Technology Co., Ltd. to create an ecological cycle model involving straw, manure, and earthworm farming [31][32]. Group 4: Circular Economy Implementation - In the sugarcane recycling processing site, sugarcane leaves are processed into feed for earthworms, which then produce high-quality organic fertilizer [38][41]. - This complete green industrial chain includes sugarcane cultivation, leaf processing, earthworm feeding, and returning organic fertilizer to the soil, enhancing soil quality and reducing chemical fertilizer usage [44][46]. Group 5: Economic Benefits and Future Plans - The innovative model resolves straw disposal issues, reduces processing costs, and provides high-quality organic fertilizer for the company [51]. - The partnership with Di Sheng Ecological Technology ensures a stable supply of raw materials and expands earthworm farming, while farmers benefit from increased income through participation in the industrial chain [52][53]. - Plans are in place to further expand the planting area, aiming to exceed 50,000 acres by 2030, enhancing the value of this green circular model [53][54]. Group 6: Sustainable Development Goals - The sugarcane industry is a vital part of Huai Ji County's agricultural industrialization, moving towards a unique green development path [56]. - The county aims to promote this successful experience and encourage more agricultural entities to participate in green cyclical farming, transitioning from a linear model to a circular resource model [58][59].
