| 摘 要： | 用4GG—170型收割机和新疆—2号联合收割机在免耕麦茬地上压地1~10次,测定土壤容重和土壤硬度随碾压次数的变化情况.结果表明,两种收割机型对土壤的压实程度有显著性差异.新疆—2号联合收割机使土壤硬度、土壤容重和孔隙度的变化程度大于前悬挂4GG—170型收割机;新疆—2号联合收割机对土壤硬度的影响超过了30 cm;新疆—2号联合收割机对土壤3~5次碾压程度相当于4GG—17型收割机碾压10次以上.

| Abstract: | No-tillage field was compacted from 1 to 10 times with 4GG-170 reaping machine and Xinjiang-2 combine harvester.Soil bulk density and soil stiffness with the increase of reaping machine stepped times were measured.The results showed that the difference of soil compaction between two kinds of reaping machine was significant.Soil compaction induced by Xinjiang-2 combine harvester was higher than 4GG-170 reaping machine.Soil stiffness was influenced by Xinjiang-2 combine harvester in depth reaching to 30 cm or more.3~5 times compaction of Xinjiang-2 combine harvester on soil was equal to 10 times above of 4GG—170 reaping machine. |
