摘要
农业机械造成的土壤压实逐渐成为一个世界性问题。为此,着重分析了影响农业机械田间土壤压实程度的因素,包括土壤含水量、机具行走、作业次数和牲畜行走。在影响因素分析的基础上,根据土壤压实的特点,提出了减少田间土壤压实的措施和技术策略。
Wheel traffic induced soil compaction has been a worldwide problem.The main factors affecting field soil compaction in agriculture operation were analyzed in this paper,including soil water content,wheel traffic,operation times and animal trampling.Then,the management and technical strategies were proposed to alleviate field soil compaction,based on factor analysis and characteristics of soil compaction.
