摘要:
根系对土壤机械压力是综合反映土壤-根系复合体相互作用的力学指标。该研究研制出了一种可利用气体或液体介质进行直接测量根系对土壤机械压力的试验装置。利用气体介质测量装置进行了模拟根系的穿插试验取得了较好的试验结果；利用液体测压试验装置进行了模拟根系穿插试验和植物生长期根系压力测定的初步试验，结果表明：装置满足压力测量试验设计的需要，具有较好的适用性和精度，可以用本试验装置直接进行根系对土壤机械压力的测量。
Abstract:
The pressure of root system on soil is a synthetically mechanical index of reflecting the root-soil composite system. An introduction to a new apparatus, which can measure the pressure of root system on soil, is designed and manufactured. The experimental data measured using the new apparatus with the air-medium and liquid-medium are obtained. The new apparatus with the liquid-medium can also meet the demands of an experiment for measuring the pressure of root system on soil during the plant growing period. It is shown by the experimental data measured using this new apparatus is suitable to measure the pressure of root system on soil with high accuracy.
