摘　　要：为探究烟草根结线虫绿色防控的技术,在根结线虫病频发的区域,采用化学农药、生物农药以及功能微生物菌剂进行烟草根结线虫病的综合防治,经过对比分析,筛选出防病效果明显的防治措施。生物有机肥、化学农药、生物农药、生防菌剂合理配施能够促进烟株生长,提高烟草经济性状,改善烟叶品质。不同处理均对根结线虫防治具有一定作用,“生物有机肥+10%噻唑膦+根据地6号生防菌剂”防控效果最佳,为96.96%;“生物有机肥+淡紫紫孢菌+根据地6号生防菌剂”和“生物有机肥+10%噻唑膦”这2个模式的防控效果差不多,分别为85.43%、84.11%;“生物有机肥+淡紫紫孢菌”这一模式与其他3个处理相比防控效果较差,仅为72.85%。“生物有机肥+10%噻唑膦+根据地6号生防菌剂”这一施肥模式对能有效提高烟叶的品质,对烟草根结线虫病的防控效果最佳。To explore the technology of green control of tobacco root knot nematode,in areas where root-knot nematode disease is frequent,chemical pesticides,biological pesticides and functional microbial agents are used to carry out comprehensive control research on tobacco root-knot nematode disease.After comparative analysis,the prevention and control measures with obvious disease prevention effect were screened.The rational application of bio-organic fertilizer,chemical pesticide,biopesticide and biofungicide can promote the growth of tobacco plants,improve the economic characteristics of tobacco and improve the quality of tobacco leaves.Different treatments had a certain effect on the control of root-knot nematodes,and the prevention and control effect of“Bio-organic fertilizer+Thiazolphosphine content 10%+Biocontrol agent No.6”was the best,and the prevention and control effect was 96.96%.The prevention and control effects of the two modes of“Bio�organic fertilizer+Purpureocillium lilacinum+Biocontrol agent No.6”and“Bio-organic fertilizer+Thiazolphosphine content 10%”were similar,which were 85.43%and 84.11%respectively.Compared with other three treatments,the prevention and control effect of“Bio-organic fertilizer+Purpureocillium lilacinum”was poor,which was only 72.85%.The fertilization mode of“Bio-organic fertilizer+Thiazolphosphine content 10%+Biocontrol agent No.6”can effectively improve the quality of tobacco leaves,and has the best effect on the prevention and control of tobacco root knot nematode disease.
