烤烟不同间作对烟草黑胫病防控效果的影响

Effect of Different Crops Intercropping with Flue-cured Tobacco on Tobacco Black Shank Disease

摘要: 为选择适宜的烤烟间作防控烟草黑胫病,通过田间试验研究了烤烟间作花生、黑麦草、大蒜对土壤烟草黑胫病菌数量、病情指数和防治效果的影响。结果表明,烤烟不同间作的土壤烟草黑胫病菌数量和病情指数趋势相同,均表现为烤烟间作大蒜<烤烟间作黑麦草<烤烟间作花生<烤烟单作,对烟草黑胫病的防控效果表现为烤烟间作大蒜>烤烟间作黑麦草>烤烟间作花生。烤烟间作大蒜对烟草黑胫病的防控效果显著较好。

Abstract: In order to choose suitable crops intercropping with flue-cured tobacco for controlling tobacco black shank disease. Field experiments were carried out to study the effects of different intercropping crops on tobacco black shank disease. Results showed that the trends of soil Phytophthora parasitica var. nicotianae number and tobacco black shank disease index were the same, with the order being intercropping with garlic ryegrass> peanut. Results also indicated that garlic was a better crop intercropping with flue-cured tobacco for controlling tobacco black shank disease.
