摘要
土壤不仅是农业生产的重要资源,也是地面车辆行使的主要介质和农业机械的工作对象;土壤的机械物理性质既关系到农作物的生产,又关系到地面车辆的通过性能、行使性能、农业机械的作业性能以及能量消耗。为此,辨析了土壤机械阻力的概念,概述了土壤机械阻力的4种测定方法及其研究状况,总结了土壤机械阻力值的一些初步应用。
The soil is not only the important resource in the agricultural production, but also the main medium of the running vehicle on ground and the working object of agricultural machine; the machinery and physical characteristics of soil also have relations with the production of agricultural crop, the passing and running properties of vehicle, and the working properties and energy exhausting of agricultural machine. Hence, the concept of soil mechanical resistance is discriminated. The methods of measuring and its function are also analyzed and summarized in this paper.
