Abstract

ABSTRACT: The uniformity of seed distribution and sowing speed directly impact crop quality and productivity. This experiment assessed how the position of the sowing monitoring sensor influences the distribution of cotton seeds using a pneumatic meter at different operating speeds. The experiment employed a completely randomized two-factor factorial design on a static simulation bench. The first factor involved the sensor installation sites (upper, middle, and lower portions of the conductor tube and conveyor belt), while the second factor encompassed simulated speeds of 3.0, 5.0, 7.0, 9.0, and 11.0 km/h. Parameters such as frequency of double, flawed, and acceptable spacing, coefficient of variation, and precision index were measured based on five replications of 250 consecutive spacing. The results indicated that the sensor’s placement significantly influences reading accuracy. Optimal results were observed when the sensor was positioned at the final portion of the conductor tube, providing more accurate seed deposition, and facilitating decision-making.
不同速度下播种机性能的种子传感器位置
摘要:种子分布的均匀性和播种速度直接影响作物的品质和产量。本实验利用气动计在不同运行速度下,评估了播种监测传感器的位置对棉花种子分布的影响。在静态模拟台上采用完全随机双因子析因设计。第一个因素涉及传感器安装位置(导体管和传送带的上、中、下部分),而第二个因素包括3.0、5.0、7.0、9.0和11.0 km/h的模拟速度。通过对250个连续间隔进行5次重复,测量了重复间隔、缺陷间隔和可接受间隔的频率、变异系数和精度指数等参数。结果表明,传感器的放置位置对读数精度有显著影响。当传感器定位在导体管的最后部分时,观察到最佳结果,提供更准确的种子沉积,便于决策。

期刊介绍: The purpose of Ciência Rural is to publish the results of original research, note and reviews which contribute significantly to knowledge in Agricultural Sciences. Preference will be given to original articles that develop news concepts or experimental approaches and are not merely repositories of scientific data. The decison of acceptance for publication lies with the Editors and is based on the recommendations of Editorial Comission, Area Committee and/ or ad hoc reviewers. The editors and reviewers are external to the institution.
