摘　　要：旋耕机作业会对土壤物理性质产生一定的影响,从而影响水稻的生长和产量。为探明旋耕机在水稻田中对土壤物理性质的影响,选取了水稻生长季节内的田间土壤样本,分别对旋耕机处理区和对照区的土壤进行物理性质的测试和比较。结果显示,旋耕机处理区的土壤容重和抗压强度明显高于对照区,而土壤的孔隙度和持水能力虽高于对照区,但不存在显著性差异。同时,旋耕机的操作还导致土壤粒径分布出现了一定程度的改变,使得土壤的整体结构发生了变化。综合分析表明,旋耕机的使用对水稻田的土壤物理性质有一定的影响,应该在实际操作中谨慎使用。Rototiller operation can have certain effects on soil physical properties,which can affect the growth and yield of rice.To investigate the effect of rototiller on soil physical properties in rice fields,this paper selected soil samples from the fields during the rice growing season,and tested and compared the physical properties of soil in the rototiller treatment and control areas,respectively.The results showed that the soil bulk and compressive strength in the rotary tiller treatment area were significantly higher than those in the control area,while the soil porosity and water holding capacity were higher than those in the control area,but there was no significant difference.At the same time,the operation of the rotary tiller also led to a certain degree of change in the soil particle size distribution,resulting in a change in the overall soil structure.The comprehensive analysis showed that the use of the rotary tiller had some effects on the soil physical properties of the rice fields and should be used with caution in practice.
