烟草花生间作控制病害与增产效应分析
Analysis of the Effects of Tobacco-Peanut Intercropping on Disease Control and Yield Increase
摘要
Abstract
To investigate the effects of intercropping tobacco(Nicotiana tabacum L.)with peanut(Arachis hypogaea L.)on disease control and yield enhancement,a two-year field trial(2023-2024)was conducted in Linyi,China.The experi-ment treatments including monocultures of tobacco(NT)and peanut(AH),as well as two intercropping patterns(T4P3 and T4P2),were set to systematically evaluate the disease incidence,agronomic traits,and economic benefits of the crops.The results showed that intercropping significantly reduced the disease index of tobacco black shank,brown spot,and viral diseases,as well as peanut southern blight,root rot,and brown spot(reduction by 50.3％-91.3％).Moreover,intercropping optimized tobacco agronomic traits(plant height,stem circumference,and leaf morphology)and increased peanut pod number per plant(7.9％-11.5％)and plump-pod rate(3.3％-8.0％).The land equivalent ratio(LER)of the intercropping system reached 1.08,with 4.25％increase in comprehensive output value compared to monocultures,and the T4P2 pattern exhibited the highest economic benefit.This study exhibited that tobacco-peanut intercropping can im-prove the ecological disease control,efficient resource utilization,and economic benefit by improving microenvironments,regulating root exudates,and enhancing soil microbial communities.These findings provided practical support for estab-lishing a tobacco-oil synergy green planting model in the Yimeng hilly tobacco-growing region,and offered essential insights for promoting sustainable agricultural development.关键词
