Abstract

Summary Cover crops and conservation soil tillage are reconsidered in cropping systems for their several agronomical and ecosystem services. In this frame, an important role is played by cover crop termination and seedbed preparation, which are crucial for a timely and successful establishment of the following cash crop. This work was aimed at testing a disc chain harrow for terminating a cover crop of hairy vetch and preparing a seedbed for soybean and defining its operational characteristics. A total of three trials were carried out to (1) compare two types of discs in two different front + rear combinations and two different working speeds (8 vs. 14 km h−1) in terms of efficacy of hairy vetch termination; (2) evaluate the seedbed preparation by the disc chain in terms of soybean establishment as a following cash crop; (3) evaluate operational characteristics (working speed, fuel consumption, absorbed power, etc.) of the disc chain at the two different speeds. Results demonstrate that the disc chain is a valid tool for cover crop termination and seedbed preparation in a conservation tillage approach. The quality of work was affected by the type of disc and the working speed. The disc chain showed good operating performance, with low mechanical pulling force, low energy requirement for traction, and low fuel consumption as compared to alternative conservation practices for cover crop termination and/or shallow soil tillage.

将圆盘链耙作为一种保护性农业工具，用于一步式覆盖作物终止和苗床准备的农艺性能

摘要由于覆盖作物和保护性土壤耕作具有多种农艺和生态系统服务功能，因此在种植系统中被重新考虑。在这一框架下，覆盖作物的终结和苗床准备发挥着重要作用，这对于及时、成功地种植下一季经济作物至关重要。这项工作的目的是测试一种圆盘链耙，用于终止毛茸茸的薇甘菊覆盖作物和为大豆准备苗床，并确定其操作特性。共进行了三次试验，目的是：(1) 比较两种类型的圆盘在两种不同的前+后组合和两种不同的工作速度（8 与 14 公里/小时）下对毛茸茸的薇甘菊的终止效果；(2) 评估圆盘链条耙的苗床准备工作对大豆作为后续经济作物的种植效果；(3) 评估圆盘链条耙在两种不同速度下的工作特性（工作速度、燃料消耗、吸收功率等）。结果表明，在保护性耕作方法中，圆盘链是终止覆盖作物和准备苗床的有效工具。工作质量受圆盘类型和工作速度的影响。与用于覆盖作物终止和/或浅层土壤耕作的其他保护性耕作方法相比，圆盘链表现出良好的操作性能，机械牵引力低，牵引所需能量低，燃料消耗低。

期刊介绍： With a focus on the tropical and sub-tropical regions of the world, Experimental Agriculture publishes the results of original research on field, plantation and herbage crops grown for food or feed, or for industrial purposes, and on farming systems, including livestock and people. It reports experimental work designed to explain how crops respond to the environment in biological and physical terms, and on the social and economic issues that may influence the uptake of the results of research by policy makers and farmers, including the role of institutions and partnerships in delivering impact. The journal also publishes accounts and critical discussions of new quantitative and qualitative methods in agricultural and ecosystems research, and of contemporary issues arising in countries where agricultural production needs to develop rapidly. There is a regular book review section and occasional, often invited, reviews of research.
