摘要： 为了解决河南烟区烟草镰刀菌根腐病严重危害烟草生产及烟叶产品质量问题，对河南省平顶山烟区郏县、宝丰等产地的烟草根腐病发病情况及主要防治措施进行了调查，初步估算了烟草根腐病造成的经济损失。以河南主栽品种中烟100为试验材料，采用固体菌剂土施、液体菌剂灌根和叶面喷施等不同的施用方法，对EM生物菌剂对大田烟草根腐病的防治效果进行了研究。固体EM菌剂土施处理研究结果表明，整地期、移栽期和培土期同时施用防治效果最好，发病率和死亡率分别为23%和16%；液体EM菌剂灌根处理研究结果表明，整地期、移栽期、团棵期、旺长期和打顶期同时施用防治效果最好，发病率和死亡率分别为18%和11%；液体EM菌剂叶面喷施的研究结果表明不同处理和对照间防治效果差别不大。综合研究结果显示，液体EM菌剂灌根对于烟草根腐病的防治具有较为显著的效果，为生产上烟草根腐病的生物防治提供了理论依据。

Abstract: The investigation of incidence and prime control?measures of tobacco root rot were made in places?such?as Jiaxian and Baofeng in Pingdingshan tobacco plant areas, in order to solve the problem that the quality and products of tobacco were seriously damaged by tobacco root rot caused by fusarium. The?economic?losses caused by tobacco root rot was also calculated. The control efficacy of EM?microbial agent by different manner such as soil application, watering application and foliar?application was studied took the main mariety Zhongyan 100 as?experimental?material. The soil application study showed that treatment at tilling stage, transplanting stage and earthing-up stage together works best. The morbidity?and?mortality were 23% and 16% respectively. The watering application study showed that treatment at tilling stage, transplanting stage, resettling?stage, fast growing stage and topping stage together works best. The morbidity?and?mortality were 18% and 11% respectively. The foliar?application study showed that there was no significant variation between different treatments and the control. Comprehensive results showed that watering application had a remarkable control effect to tobacco root rot. This results provided some theoretical references for the?biological?control of tobacco root rot.
