摘　　要：为提高农机作业效率和土壤利用率,研究不同轮胎参数对土壤的影响。该文选取拖拉机胎面花纹、轮胎胎压和轮胎尺寸为影响因素,以土壤压实度为评价指标,开展了三因素三水平正交试验。通过试验结果的分析可知,深花纹设计能够提供更好的抓地力,但会增加土壤的挤压;轮胎胎压的调节能够在一定范围内影响土壤紧实度,高胎压能够减少土壤的挤压,但也降低了抓地力,大尺寸轮胎能够降低单位面积上的压力,减缓土壤的压实程度。综合考虑,该文选取中等花纹轮胎、胎压为435 psi、轮胎尺寸为1.2 m,能够最大程度地减少对土壤的负面影响,保护土壤结构和生态环境,提高农业生产效率。In order to improve the efficiency of agricultural machinery operation and soil utilization,the influence of different tive parameters on soil can be studied.In this study,tractor tread pattern,tire pressure and tire size were selected as the influencing factors,and soil tightness was used as the evaluation index to carry out a three-factor,three-level orthogonal experiment.Through the analysis of the experimental results,it can be seen that the deep tread design can provide better grip,but it will increase the extrusion of soil;the regulation of tire pressure can affect the soil compaction within a certain range,high tire pressure can reduce the extrusion of soil,but it also reduces the grip,and the large-size tires can reduce the pressure per unit area,slowing down the degree of soil compaction.Taken together,this paper selects medium tread tires,tire pressure of 435 psi,tire size of 1.2 m,which can minimize the negative impact on the soil,protect the soil structure and ecological environment,and improve the efficiency of agricultural production.
