烟草根结线虫病绿色防控技术研究

Research on Green Prevention and Control Technology of Tobacco Root-Knot Nematode Disease

探讨不同处理对烟草根结线虫的防治效果。6种不同试验材料用于‘云烟87’根结线虫防治,以烟株生育期、采收烘烤前农艺性状、病情指数、防治效果、经济性状、感官质量评价数据为考量依据,评价不同处理对根结线虫防治及烟草质量的影响。不同处理均对根结线虫防治具有一定作用,处理5和处理7病情指数低,防治效果最好。综合农艺性状、病情指数、防治效果、经济性状、感官质量评价数据,根据地6-2号+有机肥根据地9号组合基础上配施金东旺为最佳,在‘云烟87’根结线虫防控各指标中均有较优良的表现,可以推广使用。

To explore the control effect of different treatments on tobacco root-knot nematodes,six different experimental materials were used to control root-knot nematodes in‘Yunyan 87’.The effects of different treatments on root-knot nematodes control and tobacco quality were assessed based on the evaluation of tobacco growth period,agronomic traits before harvest and curing,disease index,control effect,economic traits and sensory quality.Different treatments had certain effects on root-knot nematode control.Treatment 5 and 7 had low disease index and best control effect.The combination of GenJuDi 6-2+organic fertilizer GenJuDi 9 combined with JinDongWang was the best according to the evaluation data of agronomic traits,disease index,control effect,economic traits and sensory quality.It has a good performance in the prevention and control of tobacco root-knot nematodes,and can be popularized.
