摘要: 为探索在不改变现有种植模式和农业生产方式、不降低土壤生产功能的前提下,实现镉砷复合污染且历年镉超标辣椒地的安全利用,施用3种材料[维地康土壤调理剂(WDK)、土传病克微生物菌剂(TCBK)和江苏天象微生物菌剂(JSTX)],评估它们对土壤-辣椒系统中重金属含量的影响。结果表明:(1)对土壤的影响:WDK、TCBK和JSTX均显著降低土壤镉(Cd)含量,降幅范围在0.05~0.09 mg/kg之间(P<0.05),同时显著增加土壤铬(Cr)含量,增幅为3.7~14.4 mg/kg(P<0.05);WDK和JSTX显著降低土壤砷(As)含量(分别降低2.7、3.9 mg/kg),而TCBK则显著增加土壤As含量(增长0.6 mg/kg)(P<0.05);3种材料对土壤汞(Hg)和铅(Pb)含量的影响均不显著(P>0.05)。(2)对辣椒的影响:3种材料均显著降低当季辣椒Cd含量,降幅为0.018~0.027 mg/kg(P<0.05),对前季辣椒Cd含量的降低效果更为显著,降幅为0.068~0.077 mg/kg(P<0.01);对辣椒Pb含量的影响不显著(P>0.05);辣椒中未检出Hg、As和Cr;WDK、JSTX显著提高了辣椒产量(增幅分别为32.2%、15.7%),而TCBK则显著降低了辣椒产量(降低7.8%)(P<0.05)。综上,WDK、TCBK和JSTX处理均能有效降低土壤Cd含量并增加土壤Cr含量,但对土壤As的影响因材料而异,对土壤Hg和Pb的影响不显著。三者均能显著降低当季和前季辣椒Cd含量,但对辣椒Pb含量无显著影响。WDK和JSTX可显著增产,而TCBK则显著减产。

Abstract:

To explore the safe utilization strategies for Cd and As co-contaminated pepper fields with excessive cadmium content, without modifying existing agricultural practices or compromising soil productivity, this study evaluated the effects of three amendments, namely Vedikang soil conditioner (WDK), Tuchuanbingke microbial agent (TCBK) and Jiangsu Tianxiang microbial agent (JSTX), on heavy metal dynamics in the soil-pepper system. The results showed that (1) WDK, TCBK and JSTX significantly reduced soil Cd content by 0.05-0.09 mg/kg (P<0.05) while increasing soil Cr content by 3.7-14.4 mg/kg (P<0.05). Notably, WDK and JSTX decreased soil As concentrations by 2.7 and 3.9 mg/kg, respectively, whereas TCBK exhibited a marginal As increment of 0.6 mg/kg (P<0.05). The effects of the three materials on the contents of mercury (Hg) and lead (Pb) in the soil were not significant (P>0.05). (2) Although Cd reductions in current-season peppers were statistically insignificant (0.018-0.027 mg/kg, P<0.05), all treatments significantly diminished Cd accumulation in previous-season peppers by 0.068-0.077 mg/kg (P<0.01). No significant alterations in Pb levels were observed across treatments, and Hg, As and Cr remained undetectable in pepper fruits. WDK and JSTX significantly increased the yield of peppers by 32.2% and 15.7%, respectively, while TCBK significantly reduced the yield by 7.8% (P<0.05). In summary, all three treatments, WDK, TCBK and JSTX, were effective in reducing soil Cd content and increasing soil Cr content, but their effects on soil As varied depending on the material, and had no significant impact on soil Hg and Pb. All three treatments could significantly reduce the Cd content of peppers in both current and previous seasons, but had no significant effect on the Pb content of peppers. WDK and JSTX could significantly increase the yield, while TCBK significantly reduced it.
