宿根蔗"碎叶-破垄-施肥-起垄"一体化技术的减肥增效研究
Study on Fertilizer Reduction and Efficiency Enhancement of Integrated"Leaf Shredding-Ridge Breaking-Fertilization-Ridging"Technology for Ratoon Sugarcane
摘要
Abstract
To address the limitations of traditional ratoon sugarcane management—including suboptimal earthing-up quality,frequent occurrence of high-position buds,severe lodging,and high labor costs—this study conducted large-scale field comparative trials in Quli Town,Fusui County,Chongzuo City,Guangxi,from 2020 to 2022.The trials systematically evaluated the integrated technology combining leaf shredding,ridge breaking,fertilization,and ridging.Results demonstrated that the technology significantly outperformed conventional practices:it effectively eliminated high-position buds,increased earthing-up height by 5-10 cm,improved the rate of effective stalks at maturity by 11.87 percentage points,and reduced lodging by 45.8％.Over the three-year study period,the integrated approach resulted in an average yield increase of 32.5％.Additionally,it extended the operational window by more than 30 days,reduced fertilizer input per ton of sugarcane by approximately 30.0％,enhanced work efficiency by 1.7-2.0 times,lowered overall production costs by 25.9％,and theoretically prolonged the ratooning cycle by 1-2 years.Analysis of soil physicochemical properties showed that the technology increased soil organic matter in the plow layer by 0.15 g/kg,reduced bulk density,and improved porosity.These findings indicate that the integrated leaf shredding,ridge breaking,fertilizing,and ridging technology achieves the dual goals of"enabling multiple operations with one machine"and"reducing fertilizer use while increasing efficiency".This lightweight and efficient cultivation model holds substantial practical value for advancing cost-effective,efficient,and sustainable sugarcane production in key sugarcane-growing regions.关键词
