摘要:
从重金属污染土壤中分离到1株具有溶镉和促生长双重特性的耐镉根际促生长菌，经形态特征和系统发育分析，该菌株初步鉴定为惠州芽孢杆菌(Bacillus huizhouensis sp.)，命名为DN14，该菌株具有溶镉、溶磷、产铁载体、产吲哚乙酸和固氮的多种性能。盆栽试验表明，当菌株DN14的接种量为 80 mL/盆时，龙葵的促生长效果最显著，株高增加28.8%，地上部生物量增加40%，地下部生物量增加50%。龙葵根、茎及叶中的镉含量也均出现明显的增加，其中根部镉含量增加与对照相比差异显著(P＜0.05)，可达42.5%，茎和叶中镉含量分别提高 32.7%和27.9%。植物-微生物联合修复技术是一种很有前途的重金属污染土壤生态环保修复技术，不仅可以显著提高植物修复效率，而且可以改良土壤，为重金属污染土壤的生态修复治理提供一种新途径。
