摘要: 烟草根结线虫病是烟草的重要病害之一,近年来在我国西南地区发生严重,尤其是四川凉山地区.本研究通过田间试验探究了不同有机肥拌菌处理对烟草根结线虫病的影响,旨在筛选对烟草线虫病有良好防控效果的拌菌有机肥,以达到提高防治效果的目的.结果表明,有机肥拌菌能防控烟草线虫病发生,且促进烟株生长.其中以根茎康+猪粪有机肥对线虫病的防控效果最佳,防效达51.88%,其次为根茎康+当地有机肥,防效为58.31%,表明有机肥拌菌技术能大幅提升微生物菌剂的控病、促生效果.该研究对烟草土传病害生物防治提供参考意义.Abstract: Tobacco root knot nematode is a most important soil-borne tobacco disease in China. In recent years, it has occurred seriously in southwest China, especially in Liangshan Prefecture of Sichuan Province. A field experiment was made to evaluate the effect of Genjingkang, a microbial agent, mixed with different organic fertilizers on the control of tobacco root-knot nematode disease.The results showed that this technology could control the occurrence of tobacco nematode disease and promote the growth of tobacco plants. A mixture of Genjingkang with pig excrement manure had the best effect for controlling the disease, the control efficiency of which was about 58.31%.The control efficiency of Genjingkang mixed with local manure was 51.88%.The above results are believed to be able to provide reference for the biological control of soil-borne tobacco diseases.
