Factors limiting the implementation of mechanical harvesting of sugarcane in Campos dos Goytacazes, RJ, Brazil

ABSTRACT The objective of this research was to identify and characterize the main technical factors that affect the deployment of the mechanized harvesting of sugarcane in Campos dos Goytacazes, Rio de Janeiro, Brazil. In general, it can be stated there were restrictive factors related to machinery, administrative management, and technical planning. We identified significant technical restrictions in the planting system, particularly in relation to the size and shape of the plots, length of the rows, row spacing, and inadequate varieties. For efficient use of mechanized harvesting, a technical planning is necessary with changes in the cropping system, adopting wider and more uniform plots regarding to its format, with rows over 500 m length and row spacing of 1.50 m and upright, productive, and deep-rooted varieties.

摘要：本研究旨在识别并表征巴西里约热内卢州坎普斯杜戈伊塔卡泽斯地区甘蔗机械化收割推广应用所涉及的主要技术影响因素。总体而言，本研究明确存在与机械设备、行政管理及技术规划相关的各类限制性因素。研究发现种植体系存在显著技术瓶颈，具体体现为地块规模与形状、单行长度、行距适配性不足，以及品种选择不当等问题。若要实现甘蔗机械化收割的高效应用，需开展针对性技术规划并优化种植体系：采用面积更大、形状更统一的地块，确保单行长度超过500米，行距设定为1.50米，并选用直立型、高产且深根的优良甘蔗品种。
