土壤阻力连续测试系统可连续获取农田压实的土壤阻力信息。为研究土壤阻力连续测试系统测试土壤阻力指数(TRI)的适用性,安排了小区对比、大田对比和工作速度影响3个试验,进行了土壤阻力指数TRI值与土壤圆锥指数CI值对比分析。试验结果表明:在表征农田土壤压实程度上,TRI值与CI值具有一致性,即利用土壤阻力连续测量系统测取的TRI数据可以反应农田土壤的压实程度;土壤阻力连续测量系统采样连续、数据信息量大和采样效率高,适合于大面积农田土壤信息快速采集,有利于变耕深耕作技术的开展;在保证系统高效、安全和测试数据稳定的前提下,试验结果显示测试系统较理想的工作速度是1.0m/s。
Soil resistance continuous testing system can continuously obtain soil compaction information of farmland resistance. In order to study the suitability of soil resistance index (TRI) in soil resistance continuous testing system, three experiments were conducted including plot comparison, field comparison and working speed. The comparative analysis of soil resistance index (TRI) and soil cone index (CI) The results showed that the TRI value and the CI value were consistent in characterizing the compaction degree of farmland soil. That is, the TRI data measured by soil resistance continuous measurement system can reflect the degree of compaction of farmland soil. The soil resistance continuous measurement system sampled continuously , Large amount of data and high sampling efficiency, suitable for rapid collection of soil information on large-scale farmland, which is conducive to the development of deep plowing and tillage technology; under the premise of high efficiency, safety and stable test data, the test results show that the test system is more ideal The working speed is 1.0m / s.
