目前，关于插领式截根技术对土壤呼吸影响的研究还很少。在本研究中，我们发现，土壤呼吸速率随插入深度的增加，在“与活根完整”和“与活根切断”的处理，但前者的下降率明显更高。切断根，特别是细根，可能是造成这一结果的原因。
Little information is available on the effect of root cutting by the collar pre-insertion technique on soil respiration. In this study, we found that soil respiration rates decreased with increasing depth of collar insertion in both the “with live roots intact” and “with live roots severed” treatments, but the rate of decrease was substantially higher in the former. The cutting of roots, especially fine roots, may be responsible for this result.
