多价抗烟草病毒病疫苗对烤烟植物性状的影响

摘要

For the situation that tobacco virus disease affected tobacco plant traits and production,set up different virus disease vaccine and control group sprayed tobacco seedlings,to explore the prevention effect of weak poison vaccine on tobacco virus disease, through the selection of terrain height consistent, balanced soil fertile, plot contiguous, surrounding crop not multifarious, plot size consistent conduct comparison test,excluded the interference of external factors, investigated and analyzed the disease in the resettling stage,prosperous stage,flat period,to conclud the effects of weak tobacco virus vaccine on tobacco disease resistance.The results showed that the control effect of TVBMV-TCP treatment was the best,could effectively reduce the occurrence of virus disease,promote tobacco normal growth,tobacco plant traits were the best,PVX-PT treatment was superior to the control, comprehensive evaluation concluded that tobacco plant spraying polyvalent virus vaccine grew well, with strong disease resistance and good plant traits.%针对烟草病毒病影响影响烟叶植物性状和产量的实际，设置不同病毒病疫苗与对照组对烟草幼苗进行喷施，探索弱毒疫苗对烟草病毒病的防治效果，通过选取地势高低一致、土质肥沃程度均衡、地块连片、周边作物不繁杂、地块大小一致的烟田进行对比试验，排除外界因素的干扰，分别在团棵期、旺长期、平顶期进行病害调查分析，得出烟草弱病毒疫苗对烟草抗病性的影响。结果表明：TVBMV-TCP处理的防治效果最好，能够有效降低病毒病的发生，促进烟叶正常生长，植物性状最好。PVX-PT处理优于对照处理。综合评价喷施多价抗病毒病疫苗的烟株大田长势良好，抗病性较强，植物性状表现优良。
