Arsenic (As) toxicity is a serious hazard to agricultural land due to growing industrialization, which has a negative effect on wheat crop yields. To address this issue, using seaweed extract and has emerged as an effective strategy for improving yield under stress conditions. However, the combined application of and seaweed extract in wheat crops under As toxicity has not been fully explored. The effectiveness of combining and seaweed extract in reducing As toxicity in wheat production was examined in this study through a 2-year pot experiment with nine treatments. These treatments included a control with no additives and two As concentrations (50 and 70 μM). At 50 and 70 μM, As was tested alone, with seaweed extract, with , and both. Significant results were achieved in reducing As toxicity in wheat crops. Arsenic at 70 μM proved more harmful than at 50 μM. The application of and seaweed extract was more effective in improving crop growth rates, chlorophyll levels, and stomatal conductance. The combined application notably decreased As concentration in wheat plants. It was concluded that applying and seaweed extract not only improves wheat growth but can also improve soil parameters under As toxicity conditions by increasing organic matter contents, boosting nutrient availability, and increasing the production of antioxidant enzymes.
由于工业化进程的不断加快，砷（As）毒性已成为农田面临的严重危害，对小麦产量产生负面影响。为解决这一问题，使用海藻提取物已成为在胁迫条件下提高产量的有效策略。然而，在砷毒性条件下，[具体物质]与海藻提取物在小麦作物中的联合应用尚未得到充分研究。本研究通过为期两年的盆栽试验，设置了九个处理，考察了[具体物质]与海藻提取物联合应用在降低小麦生产中砷毒性方面的有效性。这些处理包括不添加任何物质的对照以及两种砷浓度（50和70 μM）。在50和70 μM浓度下，分别单独测试了砷、与海藻提取物一起测试、与[具体物质]一起测试以及同时与两者一起测试。在降低小麦作物砷毒性方面取得了显著成果。70 μM的砷比50 μM的砷危害更大。[具体物质]和海藻提取物的应用在提高作物生长速率、叶绿素水平和气孔导度方面更有效。联合应用显著降低了小麦植株中的砷浓度。研究得出结论，施用[具体物质]和海藻提取物不仅能促进小麦生长，还能通过增加土壤有机质含量、提高养分有效性和增加抗氧化酶的产生，改善砷毒性条件下的土壤参数。
