摘要
为探明烤烟间作半夏对烤烟产量、品质和经济效益的影响,设置烤烟单作(CK)及半夏与烤烟分别按照1∶2(C1)、1∶3(C2)、1∶4(C3)的比例进行间作共4个处理,研究烤烟间作半夏对烤烟农艺性状、抗病性、产量、品质和经济性状的影响。结果表明,相对于单作,烤烟间作半夏显著提高了烤烟的株高和最大叶面积,改善了烤烟冠层形态;显著减少了赤星病病害的发生,相对防治效果为45%(C1)、30.7%(C2)和38.2%(C3)。并且,间作半夏提高了烤烟上、中、下部叶的中性致香物质总量,改善了烟叶品质;提高了上等烟比例和经济效益。其中,半夏与烤烟1∶2间作处理的综合收效较单作提高6.1%,整体表现最好,为缓解烟草连作障碍、实现助农增收提供了新途径。
To explore the influence of flue-cured tobacco intercropping with Pinellia ternata on the yield and quality of flue-cured tobacco and economic benefit,4 treatments were set up including flue-cured tobacco monoculture(CK)and flue-cured tobacco intercropping with Pinellia ternata according to 1∶2(C1),1∶3(C2)and 1∶4(C3).The agronomic characters,disease resistance,yield,quality and economic characters of flue-cured tobacco were determined.The results showed that,compared with CK,the model of flue-cured tobacco intercropping with Pinellia ternata had significant effects on the agronomic traits of flue-cured tobacco,which significantly increased plant height and maximum leaf area,and improved canopy morphology.In terms of controlling diseases and insect pests,the intercropping model with Pinellia ternata could significantly reduce the occurrence of red spot disease,which the relative control effect was 45%(C1),30.7%(C2)and 38.2%(C3),respectively.Compared with CK,the intercropping model with Pinellia ternata increased the total amount of neutral aroma substances in the upper leaves,middle leaves and lower leaves,and improved fine tobacco ratio and high economic benefit.Among 3 intercropping treatments,C1 treatment showed that the comprehensive benefit increased by 6.1%than CK treatment,which provided a new way to reduce obstacles of tobacco continuous cropping and increase economic income of farmers.
