    摘要:

    研究了華北平原小麥、玉米一年兩熟區(qū)固定道保護(hù)性耕作對(duì)機(jī)具田間牽引阻力的影響,對(duì)比分析了固定道與非固定道處理下機(jī)具田間作業(yè)的滾動(dòng)阻力、開(kāi)溝器牽引阻力和總牽引阻力。與非固定道保護(hù)性耕作時(shí)深松、小麥和玉米播種作業(yè)相比,固定道保護(hù)性耕作下機(jī)組總牽引阻力分別降低14.6%、13.3%和13.3%;滾動(dòng)阻力分別降低26.9%、21.9%和19.7%,平均降低22.9%;機(jī)具牽引阻力分別降低7.5%、7.2%和12.4%,平均降低8.8%。固定道處理的開(kāi)溝器牽引阻力平均比非固定道處理降低22.0%。與非固定道相比,固定道總牽引油耗在3種作業(yè)時(shí)分別降低17.6%、12.4%和9.1%。試驗(yàn)結(jié)果表明,固定道保護(hù)性耕作顯著降低機(jī)具田間牽引阻力,減少了機(jī)具田間作業(yè)油耗。

    Abstract:

    Controlled traffic with conservation tillage (CTCT) can reduce soil compaction, thus to improve operation performance of agricultural machine, by separating wheel track and crop zone. The effect of CTCT on operation resistance force was researched in annual two crops region in Northern China. The rolling resistance, opener resistance and total draft between controlled and non-controlled traffic treatments were analyzed. In subsoiling, wheat and maize planting, compared with non-controlled traffic with conservation tillage, CTCT total draft reduced by 14.6%, 13.3% and 13.3%, rolling resistance reduced by 26.9%, 21.9% and 19.7%, averaging 22.9%, working resistance reduced by 7.5%, 7.2% and 12.4%, averaging 8.8%. Opener resistance reduced 22.0% averagely in controlled traffic treatments than that in non-controlled traffic treatments. As the resistance decreased, fuel consumption in controlled traffic treatment reduced by 17.6%, 12.4% and 9.1% in three operations. Results showed that controlled traffic conservation tillage reduces agricultural machine working resistance and fuel consumption in field operation.
