This study was conducted to assess the effects of solarization and biosolarization on the degradation of oxyfluorfen, ethalfluralin, trifluralin, propyzamide, and pendimethalin. The experimental design consisted of 17 L pots filled with clay-loam soil, which were contaminated with the studied herbicides. Then, soil disinfection treatments were applied during the summer season, including a control without disinfection (C), solarization (S), and biosolarization (BS). Soil from five pots per treatment was sampled periodically up to 90 days. Herbicide dissipation rates were higher in both S and BS treatments with regard to the control. Similar dissipation rates were observed under S and BS for most of the herbicides studied, except oxyfluorfen and pendimethalin, which were degraded to a greater extent in the BS than in the S treatment. The obtained results showed that both solarization and biosolarization can be considered, in addition to soil disinfection techniques, such as bioremediation tools for herbicide-polluted soils.
本研究旨在评估太阳能消毒和生物太阳能消毒对氟氧氟草酯、乙草胺、氟乐灵、异丙甲草胺和二甲戊灵降解的影响。实验设计包括 17 升罐装满粘壤土，用研究中的除草剂污染。然后，在夏季进行土壤消毒处理，包括不消毒对照（C）、太阳能消毒（S）和生物太阳能消毒（BS）。每个处理组的五个罐中的土壤定期取样，直到 90 天。与对照相比，S 和 BS 处理中除草剂的消解速率更高。在 S 和 BS 处理下，除了氟氧氟草酯和二甲戊灵外，大多数研究的除草剂都观察到相似的消解速率，在 BS 处理中比在 S 处理中降解得更彻底。研究结果表明，太阳能消毒和生物太阳能消毒除了土壤消毒技术外，还可以作为受除草剂污染土壤的生物修复工具。
