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。

Abstract:

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.
