Soil Fumigation Techniques for Chinese Cabbage

Field experiment was conducted during the growing season from June to August 2021 under four different situations: NB; soil fumigation with lime (0.15 kg/m²), N; soil fumigation with ammonium bicarbonate (0.15 kg/m²), LNB; soil fumigation with combined lime (0.15 kg/m²) and ammonium bicarbonate (0.15 kg/m²), and GZ; no soil fumigation as control. After soil amendments with ammonium bicarbonate and lime, the field was divided into plots (3 m × 9 m) and covered with 0.08 mm film for 15 days for anaerobic soil fumigation. The experiment was performed using a randomized complete block design and repeated three times with 3 plots/treatment (in total 12 plots), and each plot contained 120 plants of Chinese cabbage. The Di, DI, CE, and soil pH from each treatment were recorded at the completion of the trial as described above using the methodology of Zhang et al. (2022a) (link).
