摘　　要：为明确从镉污染植烟土壤中筛选得到的耐镉细菌TU菌及其不同配施方式对烟叶镉含量及品质的影响,进一步揭示其对土壤镉污染的修复效果,设置对照(CK)、TU菌(T1)、TU菌+腐殖酸(T2)、TU菌+尿素(T3)、TU菌+磷酸钾(T4)5个处理进行大田试验,比较5个处理烟叶镉含量、外观质量、化学成分及评吸质量的差异。结果表明:与CK比较,T1、T2、T3、T4处理烤后烟叶的镉含量分别降低了32.79%、44.75%、-18.20%、32.46%;不同处理烟叶外观质量表现为T2>T4>T1>CK>T3;化学成分以T2和T1处理最为协调,T3处理最差;评吸质量得分表现为T2>T4>T1>CK>T3。因此,生产过程中施用TU菌对烟叶有降镉提质作用,腐殖酸对TU菌降低烟叶镉含量和提高烟叶质量的功效具有加成作用。In order to clear the effects of TU and its different combined application modes on Cd content and quality of tobacco leaves, to further reveal its remediation effect, we set up the treatments ： control （CK） , TU （ T1） , TU ＋ humic acid（ T2 ） , TU ＋ urea （ T3 ） , TU ＋ potassium phosphate （ T4 ） to conduct the field experiment. The differences of Cd content of tobacco, tobacco appearance quality, chemical composi-tion and smoking quality among 5 kinds of Cd application mode were studied. The results showed that compared with CK, Cd contents of tobacco leaves in T1 , T2 , T3 , T4 treatments were decreased by 32.79% ,44.75% , -18.20% ,32.46% respectively; the order of appearance quality of the tobacco leaf was T2 〉 T4 〉 T1 〉 CK 〉 T3 ; chemical composition in T2 and T1 treatments were the most harmonious,T3 treatment was the worst; the order of smoking quality of the tobacco leaf was T2 〉 T4 〉 T1 〉 CK 〉 T3.So applying TU during production could reduce the Cd content and improve the quality of tobacco leaf. Humic acid could enhance the efficacy of TU.
