摘　　要：研究空茬期烟田养鸡对烟草主要病虫害的影响,结果表明,空茬期烟田养鸡后,在第20天时显著(P<0.05)降低小地老虎对烟草的被害株数和断苗率;30和40 d时,试验组烟蚜发病率显著低于对照组(P<0.05);试验组黑胫病发病率与对照组无显著差异(P≥0.05);40 d时,试验组烟青虫发病率显著低于对照组(P<0.05);30和40 d时,由农药残留引起的畸形叶试验组显著低于对照组(P<0.05)。空茬期烟田养鸡能有效减少部分病虫害的发生。The effects of raising chickens in the empty stubble period on the main diseases and insect pests of tobacco were studied.The results showed that after raising chickens in the empty stubble period,the number of killed plants and the rate of broken seedlings of small ground tigers on the 20th day were significantly reduced(P<0.05).At 30 and 40 d,the incidence of tobacco aphid disease in the experimental group was significantly lower than that in the control group(P<0.05).There was no significant difference in the incidence of black shank disease between the experimental group and the control group(P≥0.05).At 40 d,the incidence of tobacco cyanosis in the experimental group was significantly lower than that in the control group(P<0.05).At 30 and 40 d,the malformed leaves caused by pesticide residues were significantly lower in the test group than in the control group(P<0.05).Raising chickens in tobacco field during empty stubble period can effectively reduce the occurrence of some diseases and insect pests.
