摘要

研究目的:开发红麻采收技术，提高红麻生产效率。本研究评估了一些操作参数对拖拉机式红麻(Hibiscus cannabinus L.)收割机性能的影响。研究区域:实验在尼日利亚Ile Ife的Obafemi Awolowo大学的教学和研究农场进行。材料与方法:在试验田种植红麻10周后开始试验。试验设计为3 × 4 × 5试验，评价红麻成熟度(种植后第10、12、14和16周平均茎粗)、红麻品种(‘Cuba 108’、‘Ifeken 400’和‘Ifeken Di 400’)和拖拉机行驶速度(2、3.5、5、6.5和7.7 km/h)对机器有效田间容量、田间效率和操作损失的影响。主要结果:该机器的有效田间容量随植株成熟度的增加而降低，随机器前进速度的增加而增加。收获‘Ifeken 400’时，作物成熟期为10 WAP，前进速度为5 km/h，有效田间容量最优值为2.13 ha/d。随着作物成熟度的增加和机器前进速度的增加，机器的田间效率降低。该机的田间效率为97%，‘Ifeken 400’作物成熟度为10 WAP，前进速度为2 km/h。研究重点:作物成熟度、红麻品种和拖拉机前进速度对红麻拖拉机收割机的有效田间容量、田间效率和作业损失有影响

Effect of operational parameters on the performance of a kenaf harvester

Aim of study: To develop a kenaf harvesting technology, that will improve kenaf production efficiency. This study evaluated the effect of some operation parameters on the performance of a tractor-mounted kenaf (Hibiscus cannabinus L.) harvester. Area of study: The experiment was performed at the Teaching and Research Farm of the Obafemi Awolowo University, Ile Ife, Nigeria. Material and methods: The experiment was initiated after 10 weeks of planting kenaf on the experimental field. The experimental design was a 3 × 4 × 5 experiment evaluating the effect of kenaf maturity (average stem diameter at week after planting (WAP) 10, 12, 14 and 16), kenaf varieties (‘Cuba 108’, ‘Ifeken 400’ and ‘Ifeken Di 400’) and forward speed of the tractor (2, 3.5, 5, 6.5 and 7.7 km/h) on effective field capacity, field efficiency, and operational loses of the machine. Main results: The effective field capacity of the machine decreased with increase in plant maturity and increased with increase in forward speed of the machine. The optimal value of the effective field capacity was 2.13 ha/day, when harvesting ‘Ifeken 400’, at crop maturity of 10 WAP, and forward speed was 5 km/h. The field efficiency of the machine was found to decrease with increase in crop maturity and forward speed of the machine. The field efficiency of the machine was 97%, with ‘Ifeken 400’ crop maturity of 10 WAP and forward speed of 2 km/h. Research highlights: The crop maturity, Kenaf variety and forward speed of tractor have effect on the effective field capacity, field efficiency and the operational loss of the tractor-mounted kenaf harvester

期刊介绍： The Spanish Journal of Agricultural Research (SJAR) is a quarterly international journal that accepts research articles, reviews and short communications of content related to agriculture. Research articles and short communications must report original work not previously published in any language and not under consideration for publication elsewhere. The main aim of SJAR is to publish papers that report research findings on the following topics: agricultural economics; agricultural engineering; agricultural environment and ecology; animal breeding, genetics and reproduction; animal health and welfare; animal production; plant breeding, genetics and genetic resources; plant physiology; plant production (field and horticultural crops); plant protection; soil science; and water management.
