Abstract:

In order to investigate the effects of different amendment methods on nutrients, enzyme activities and fungal community structure in ginseng continuous cropping soil, the experiment was conducted using untreated old ginseng soil (LSD) as a control. Two treatment groups were set up: one treated with ammonium bicarbonate (CS) under high temperature and the other treated with strong reducing soil sterilization using Faeces Trogopterori as a carbon source (WLZ). The changes of soil physical and chemical properties and fungal community were analyzed by chemical analysis and high-throughput sequencing technology. The data showed that both improved treatments increased soil pH, organic matter (OM), quick-acting phosphorus (AP) and alkaline dissolved nitrogen (AN), as well as the enzyme activities of urease (UE) and acid phosphatase (ACP), and decreased the abundance of the soil fungal community, as compared with the LSD treatment. A total of 44 phyla, 113 classes, 204 orders, 308 families and 480 genera were detected in soil samples. Correlation analysis shows that soil nutrient content OM, AP, AN, and pH all closely affect changes in fungal communities. In summary, both treatments can improve soil nutrient status and reconstruct fungal communities. Therefore, effectively combining the two methods is expected to become a new approach for restoring degraded soil.
