“…China is the largest producer of greenhouse vegetables (facility farmlands) worldwide (Yuan et al, 2022). Sunlight, temperature, and humidity inside the facility farmland are controlled for the production of high-quality vegetables, fruits, and crops throughout the year; thus, the microclimate inside the facility is significantly different from that of an open farmland (Liu et al, 2021).…”

In the future, the frequency, duration, and intensity of extreme weather may increase, thus posing a threat to soil biodiversity in farmlands, particularly in agricultural production bases. However, little is known about the effect of cold wave events on the soil fauna community compared with other extreme weathers. Laboratory experiments fail to capture the complicated field environment of cold wave events. We investigated soil fauna communities in facility farmland (strawberry) and open farmland (green cabbage) during a cold wave event in Ningbo City, southeastern China. The results showed that the taxonomic richness of the total soil fauna community in facility farmland was significantly lower than that in open farmland, but the difference in abundance was not significant. The taxonomic richness and body size of soil mites and collembolan communities in facility farmland were significantly lower than those in the open farmland. Obvious differences in abundance, mean body length, mean body width, and ratio of body width to body length of Scheloribatidae, Galumnidae, Onychiuridae, Entomobryidae, and Enchytraeidae were detected between facility farmland and open farmland. The results of this study showed that the taxonomic richness, abundance, and body size of the soil fauna community in open farmland were significantly higher than those in facility farmland during a cold wave event. We suggested that the open farmland could be a “refuge” and “hot spot” of soil fauna community during the cold wave events.

Massive antibiotic resistance genes (ARG) were detected in the soil modi ed by manure, which may affect human life safety through the food chain. However, the transmission of ARGs through the soil-plant-animal food chain is still unclear. Therefore, this study used high-throughput quantitative PCR technology to explore the effects of pig manure application on ARGs and bacterial communities in soil, lettuce phyllosphere and snail excrement.The results showed that a total of 384 ARGs and 48 MEGs were detected in all samples after 75 days of incubation. The diversity of ARGs and MGEs in soil components increased signi cantly by 87.04%and 40%with the addition of pig manure. The absolute abundance of ARGs in the phyllosphere of lettuce was signi cantly higher than that of the control group, with a growth rate of 212.5%.Six common ARGs were detected between the three components of the fertilization group, indicating that there was internal transmission of fecal ARGs between the trophic levels of the food chain.Firmicutes and Proteobacteria were identi ed as the dominant host bacteria in the food chain system, which were more likely to be used as carriers of ARGs to promote the spread of resistance in the food chain.The results were used to evaluate the potential ecological risks of livestock and poultry manure and provide theoretical basis and scienti c support for the formulation of ARGs prevention and control policies.
