| 摘 要： | 为了解决大豆田除草剂氟磺胺草醚长期施用造成土壤中大量残留对后茬敏感作物的药害问题,本研究通过盆栽试验研究添加细菌发酵液对玉米种子的发芽率和幼苗生长指标的影响,通过田间试验研究添加细菌发酵液对土壤和玉米籽粒中氟磺胺草醚残留和玉米产量的影响。盆栽试验表明土壤处理30天和60天处理组的玉米出苗率差异极显著,根干重差异显著;菌液处理土壤30天时,残留氟磺胺草醚对后茬敏感作物玉米幼苗生长影响较小;田间试验表明收获时土壤中未检测出氟磺胺草醚,玉米吸收了86.91%~97.87%氟磺胺草醚,施用菌液后玉米籽粒对氟磺胺草醚的残留率下降了21.8%~32.76%,使其残留量符合国家标准,而且能够增加玉米株棒数和平均产量。菌液施用对氟磺胺草醚污染的土壤具有较好的修复作用且能够减轻氟磺胺草醚对后茬玉米的药害现象。

| Abstract: | To solve the problem that a large number of residues in soil caused by the long-term application of the herbicide fomesafen in soybean field is harmful to sensitive succession crops, in this study, the pot experiment was conducted to investigate the effect of adding bacterial fermentation liquid on germination rate of maize seeds and seedling growth index, and a field experiment was conducted to explore the effect of adding bacterial fermentation liquid on the residue of fomesafen in soil and maize grain and maize yield. Pot experiment showed that there were extremely significant differences in the emergence rates of maize between the 30 d and 60 d soil treatment groups, and there were significant differences in dry weights of roots. When the soil was treated with bacterial solution for 30 days, the residual fomesafen had little effect on the growth of maize seedlings. The results of field experiments showed that no fomesafen was detected in soil at harvest time, and 86.91%-97.87% fomesafen was absorbed by maize. The residual rate of fomesafen in maize seeds decreased by 21.8%-32.76% after the application of bacterial solution, which made the residue meet the national standard, and increased the number of maize sticks and the average yield of maize. The application of bacterial solution has a better remediation effect on the soil polluted by fomesafen and could reduce the harmful phenomenon of fomesafen to the following maize. |
