The primary bottleneck restricting sugarcane harvesting mechanization in Chinaʼs hilly regions is fragmented terrain combined with narrow-row, high-density planting. This study was aimed to systematically analyze the effects of a two-step mechanical harvesting model on production efficiency, raw material quality, and farmer' income, thereby clarifying its application potential and promotion strategies in these regions. During the 2023/2024 and 2024/2025 harvesting seasons in Gengma, field experiments and cost-benefit analyses were conducted to compare four harvesting models, Combine Harvesting, Traditional Manual, Commissioned Processing, and Raw Cane Sale. Statistical methods, including ANOVA, were employed to analyze the effects of sugarcane growth stages and major cultivars on the impurity rate of raw materials. The Commissioned Processing model increased farmerʼs net income to 365.00 yuan/t over the Traditional Manual model (farmerʼs net income 318.00 yuan/t), an increase of 14.80%, while reducing harvesting costs 42.06%. The income was comparable to the Combine Harvesting model but effectively avoided the severe damage to sugarcane ratoons caused by the latter. Regarding raw material quality, genetic differences among cultivars had no significant effect on the impurity rate, whereas harvest time was the dominant factor. As the harvest period was extended from December to the following April, the net cane rate under Traditional Manual model significantly increased from 75.76% to 84.90%. Correspondingly, the impurity rate of two-step mechanized harvesting decreased from 6.42% to 4.52%, indicating that scheduling operations within the full maturity window after January effectively controls raw material impurities. The study also revealed a misalignment between the commercial impurity deduction standards of sugar mills and field-measured impurity rates. This discrepancy, characterized by significant inter-varietal differences, could hinder the fair promotion of this new technology. The two-step mechanical harvesting model is an optimal choice for Chinaʼs hilly regions, balancing economic benefits with ecological sustainability. Its promotion strategy should prioritize establishing a precise operational timetable based on sugarcane growth stages rather than developing differentiated harvesting systems for existing cultivars. This model would provide a quantifiable and scalable solution for mechanization in hilly sugarcane areas, holding significant practical value and strategic importance for enhancing the competitiveness of national sugar industry and ensuring sugar security.

针对我国丘陵蔗区因地形破碎与窄行密植导致甘蔗收获机械化受限的产业瓶颈,本研究旨在系统解析分步式机收模式对生产效率、原料质量及蔗农收益的影响,以明确其在丘陵蔗区的应用潜力与推广策略。以云南耿马蔗区为研究区域,基于2023/2024、2024/2025榨季云南耿马蔗区实例,采用多源数据融合分析(自然生长含杂质溯源试验,分步式机收含杂质溯源、成本监测),系统比较“联合机收”“传统人工”“委托加工”和“毛蔗交售”4种收获模式的经济效益。采用方差分析等统计方法,解析甘蔗生育进程与主栽品种对原料含杂率的影响机制。结果表明:经济效益上,与“传统人工”模式(蔗农净收益318.00元/t)相比,分步式机收的“委托加工”模式使蔗农净收益提升至365.00元/t,增幅达14.80%,且收获成本降低42.06%,该收益接近“联合机收”模式,且有效规避了后者对宿根蔗蔸的损伤。原料质量控制上,品种遗传差异对含杂率无显著影响,而收获时间是主导因素。随着收获期从12月推至次年4月,人工砍收下的甘蔗净蔗得率从75.76%显著提升至84.90%;而分步式机收的含杂率也从6.42%显著降至4.52%,选择在1月份之后甘蔗充分成熟的窗口期作业,可有效控制原料杂质。本研究还发现,糖厂的商业扣杂标准与田间实测含杂率存在“评价错位”,表现出显著的品种间差异,可能影响新技术的公平推广。分步式机收是适应我国丘陵山地特点,兼顾经济效益与生态可持续性的优选收获模式,其推广策略应优先聚焦于建立基于生育进程的作业时间表,而非为现有品种开发差异化的收获系统。该模式为丘陵蔗区机械化提供可量化、可推广的解决方案,对增强我国糖业竞争力与保障糖业安全具有重要实践价值和战略意义。

针对我国丘陵蔗区因地形破碎与窄行密植导致甘蔗收获机械化受限的产业瓶颈,本研究旨在系统解析分步式机收模式对生产效率、原料质量及蔗农收益的影响,以明确其在丘陵蔗区的应用潜力与推广策略。以云南耿马蔗区为研究区域,基于2023/2024、2024/2025榨季云南耿马蔗区实例,采用多源数据融合分析(自然生长含杂质溯源试验,分步式机收含杂质溯源、成本监测),系统比较“联合机收”“传统人工”“委托加工”和“毛蔗交售”4种收获模式的经济效益。采用方差分析等统计方法,解析甘蔗生育进程与主栽品种对原料含杂率的影响机制。结果表明:经济效益上,与“传统人工”模式(蔗农净收益318.00元/t)相比,分步式机收的“委托加工”模式使蔗农净收益提升至365.00元/t,增幅达14.80%,且收获成本降低42.06%,该收益接近“联合机收”模式,且有效规避了后者对宿根蔗蔸的损伤。原料质量控制上,品种遗传差异对含杂率无显著影响,而收获时间是主导因素。随着收获期从12月推至次年4月,人工砍收下的甘蔗净蔗得率从75.76%显著提升至84.90%;而分步式机收的含杂率也从6.42%显著降至4.52%,选择在1月份之后甘蔗充分成熟的窗口期作业,可有效控制原料杂质。本研究还发现,糖厂的商业扣杂标准与田间实测含杂率存在“评价错位”,表现出显著的品种间差异,可能影响新技术的公平推广。分步式机收是适应我国丘陵山地特点,兼顾经济效益与生态可持续性的优选收获模式,其推广策略应优先聚焦于建立基于生育进程的作业时间表,而非为现有品种开发差异化的收获系统。该模式为丘陵蔗区机械化提供可量化、可推广的解决方案,对增强我国糖业竞争力与保障糖业安全具有重要实践价值和战略意义。

The primary bottleneck restricting sugarcane harvesting mechanization in Chinaʼs hilly regions is fragmented terrain combined with narrow-row, high-density planting. This study was aimed to systematically analyze the effects of a two-step mechanical harvesting model on production efficiency, raw material quality, and farmer' income, thereby clarifying its application potential and promotion strategies in these regions. During the 2023/2024 and 2024/2025 harvesting seasons in Gengma, field experiments and cost-benefit analyses were conducted to compare four harvesting models, Combine Harvesting, Traditional Manual, Commissioned Processing, and Raw Cane Sale. Statistical methods, including ANOVA, were employed to analyze the effects of sugarcane growth stages and major cultivars on the impurity rate of raw materials. The Commissioned Processing model increased farmerʼs net income to 365.00 yuan/t over the Traditional Manual model (farmerʼs net income 318.00 yuan/t), an increase of 14.80%, while reducing harvesting costs 42.06%. The income was comparable to the Combine Harvesting model but effectively avoided the severe damage to sugarcane ratoons caused by the latter. Regarding raw material quality, genetic differences among cultivars had no significant effect on the impurity rate, whereas harvest time was the dominant factor. As the harvest period was extended from December to the following April, the net cane rate under Traditional Manual model significantly increased from 75.76% to 84.90%. Correspondingly, the impurity rate of two-step mechanized harvesting decreased from 6.42% to 4.52%, indicating that scheduling operations within the full maturity window after January effectively controls raw material impurities. The study also revealed a misalignment between the commercial impurity deduction standards of sugar mills and field-measured impurity rates. This discrepancy, characterized by significant inter-varietal differences, could hinder the fair promotion of this new technology. The two-step mechanical harvesting model is an optimal choice for Chinaʼs hilly regions, balancing economic benefits with ecological sustainability. Its promotion strategy should prioritize establishing a precise operational timetable based on sugarcane growth stages rather than developing differentiated harvesting systems for existing cultivars. This model would provide a quantifiable and scalable solution for mechanization in hilly sugarcane areas, holding significant practical value and strategic importance for enhancing the competitiveness of national sugar industry and ensuring sugar security.
