摘　　要：本研究采用41.7%氟吡菌酰胺随定根水灌根和喷塘2种不同施药方式,与41.7%氟吡菌酰胺加3亿/mL解淀粉芽孢杆菌随定根水灌根、传统的10%噻唑膦GR穴施进行防效比较,并测量株高、叶宽与收益,筛选防治烟草根结线虫效果与收益均提高的农药与用药方法。结果表明,采收后线虫防治效果、叶宽、须根比率与收益排序依次是:41.7%氟吡菌酰胺+3亿/mL解淀粉芽孢杆菌灌根>41.7%氟吡菌酰胺灌根>41.7%氟吡菌酰胺喷塘>10%噻唑膦GR穴施;株高依次为41.7%氟吡菌酰胺+3亿/mL解淀粉芽孢杆菌灌根>41.7%氟吡菌酰胺喷塘>41.7%氟吡菌酰胺灌根>10%噻唑膦GR穴施。综合考虑,41.7%氟吡菌酰胺+3亿/mL解淀粉芽孢杆菌灌根、 41.7%氟吡菌酰胺灌根均能更有效地防治线虫,并减少用工、提高收益。The efficacy of 41.7% flupyramide applied by chemigation and planting station spray was compared to 41.7% flupyramide plus 300 million/mL Bacillus amyloliquefaciens chemigation and traditional 10% thiazole phosphine GR planting station broadcast in this study. Plant height, leaf width, and net profits were measured to screen the pesticides and application methods which can improve both the controlling efficacy of tobacco root knot nematodes and net profits. The results showed that the order of nematode control effectiveness, leaf width, rootlets ratio, and profits after harvesting was as follows: 41.7% flupyramide + 300 million/mL B. amyloliquefaciens chemigation > 41.7% flupyramide chemigation > 41.7% flupyramide planting station spray > 10% thiazole phosphine GR planting station broadcast. The order of plant height is 41.7% flupyramide + 300 million/mL B. amyloliquefaciens chemigation > 41.7% flupyramide planting station spray > 41.7% flupyramide chemigation > 10% thiazole phosphine GR plant station broadcast. In a word, chemigation with 41.7% flupyramide and 300 million/mL B. amyloliquefaciens , as well as chemigation with 41.7% flupyramide, can effectively control nematodes, reduce labor costs, and increase profits.
