摘要:

随着我国设施农业的快速发展,次生盐渍化问题日益严重,严重影响作物生长和土壤健康。本研究探讨了生物炭与巨大芽孢杆菌协同应用对次生盐渍化土壤的改良效果。通过盆栽试验,研究了生物炭配施巨大芽孢杆菌对土壤理化性质、硝酸盐含量及黄瓜生长的影响。结果表明,添加生物炭和巨大芽孢杆菌的处理(BT1和BT2)显著(p<0.05)降低了土壤电导率(EC)和硝酸盐含量。其中,BT2处理下的土壤EC值比对照(CK)降低了47.25%,硝酸盐含量也显著下降。添加生物炭和巨大芽孢杆菌的处理还显著提高了土壤酶活性和微生物数量。同时,施加生物炭和巨大芽孢杆菌的处理显著提高了黄瓜的株高、茎粗、地上部干/鲜重及根系活力,显著提高了黄瓜叶片的保护酶活性,并降低了丙二醛含量。以上结果表明,生物炭与巨大芽孢杆菌的协同作用在次生盐渍化土壤修复中具有显著优势,为设施农业土壤改良提供了理论依据和技术支持。

Abstract:

With the rapid development of greenhouse agriculture in China,secondary salinization has become increasingly severe,significantly affecting crop growth and soil health. This study investigated the effects of combining biochar with Bacillus megaterium on the remediation of secondary salinized soil. Through pot experiments,the effects of biochar combined with Bacillus megaterium on soil physicochemical properties,nitrate content,and cucumber growth were investigated. The results showed that treatments incorporating biochar and Bacillus megaterium(BT1 and BT2)significantly(p<0.05)reduced soil electrical conductivity(EC)and nitrate content. Specifically,the EC value of the soil under BT2 treatment was 47.25% lower than that of the control(CK),and nitrate content also decreased significantly. Additionally,the application of biochar and Bacillus megaterium significantly improved soil enzyme activity and microbial abundance. Simultaneously,the treatment of applying biochar and Bacillus megaterium significantly increased cucumber plant height,stem thickness,above-ground dry and fresh weight,and root vitality. The treatment also significantly enhanced the activities of antioxidant enzymes in cucumber leaves and reduced the content of malondialdehyde(MDA). These findings indicated that the synergistic effect of biochar and Bacillus megaterium is highly effective in the remediation of secondary salinized soil,providing theoretical support and technical guidance for sustainable soil management in greenhouse agriculture.
