SY—1型静载式水田土壤承压仪能自动记录水田土壤的垂直应力——应变关系,说明土壤的密实程度或承载能力随深度变化的情况。可供水田拖拉机或农业机械研究时鉴定土壤的物理状态和预计这些机具在水田中工作时可能的下陷深度和滚动阻力之用。它也能为设计拖拉机或农业机械的行走机构提供依据。该仪器由吉林工业大学设计,南京土壤仪器厂试制。研制过程中,
SY-1 type of static load paddy soil pressure gauge can automatically record the vertical soil stress-strain relationship of paddy soil, indicating the density of soil or bearing capacity changes with depth. Field studies of paddy field tractors or agricultural machinery may be used to identify the physical state of the soil and to predict the possible subsidence depth and rolling resistance of such implements when working in paddy fields. It also provides the basis for the design of tractors or agricultural machinery travel agencies. The instrument designed by Jilin University of Technology, Nanjing Soil Instrument Factory pilot. During the development,
