SIMULATION OF DISTANCE BETWEEN FIELD AND REPLENISHMENT PUMP IN MECHANIZED SPRAYING OF SUGARCANE (Saccharum spp.)

ABSTRACT Brazil is the world's largest producer of sugarcane destined for mills. Spraying in sugarcane plantations is carried out in extensive cultivation areas and with self-propelled, tractor-driven, and aerial hydraulic equipment. For this, a good positioning of the replenishment pump of agricultural defensives close to the field where the spraying is carried out is necessary. However, it is desirable that the replenishment be carried out at short distances between the field and replenishment pump. This study aimed to assess the impact of the distance between the field and replenishment pump on the operational cost of hydraulic sprayers for sugarcane farming practices. Due to the difficulty in accomplishing the work and meeting the objective under field conditions, we decided to develop a computational model called “TratoCana” in a spreadsheet and programming language. The model was verified for possible routine errors, validated, and used in the analysis of factors and in the generation of scenarios. The results showed that the increased average distance between the field and replenishment pump has a negative impact on the operational and economic performance of the machine.

摘要：巴西是全球最大的专供制糖厂的甘蔗生产国。甘蔗种植园的植保施药作业覆盖广袤的种植区域，所使用的设备包括自走式、拖拉机牵引式以及航空液压施药装置。为此，需将农业植保药剂补给泵妥善布置在施药田块附近，但理想情况下应尽量缩短施药田块与补给泵之间的距离。本研究旨在评估田块与补给泵之间的距离对甘蔗种植植保液压喷雾机作业成本的影响。由于在田间条件下难以完成相关研究并达成研究目标，我们决定采用电子表格与编程语言开发一款名为"TratoCana"的计算模型。该模型经常规误差校验、有效性验证后，被用于因素分析与场景生成。研究结果表明，田块与补给泵之间的平均距离增加，会对喷雾机的作业与经济性能产生负面影响。
