不同诱抗剂对烟草马铃薯Y病毒病和气候斑点病的防效及植株性状的影响
|
摘要
以毕纳1号烟草为供试材料,研究8种诱抗剂对烟草马铃薯Y病毒病(PVY)和气候斑点病的控制作用及对烟株性状的影响。结果表明,8种诱抗剂对烟草PVY相对防效达到20.55%~42.57%(威宁黑石点)和20.95%~36.93%(纳雍龙场点)对烟草气候斑点病相对防效达到16.26%~74.72%(威宁黑石点)和24.34%~73.12%(纳雍龙场点);其中综合防效较好的诱抗剂为甲基硫菌灵+碧护+磷酸二氢钾混配和植物酚多精+氨基寡糖素+磷酸氢二钾混配。喷施诱抗剂能够增强烟株长势,提高烟叶叶绿素相对含量,改善烟叶农艺性状,提高烟株抗病性。
Tobacco variety 'Bina No.1' was used as experimental material to study the effects of eight inducers on agronomic traits and control of potato virus Y and weather fleck of tobacco.The results indicated that the field control efficiencies of eight inducers against potato virus Y were 20.55%-42.57%in Heishi town of Weining Country and 20.95%-36.93%in Longchang town of Nayong Country,respectively,and against weather fleck 16.26%-74.72%in Heishi town of Weining County and 24.34%-73.12%in Longchang town of Nayong Country respectively.Among eight inducers Thiophanate methyl + Bihu + Potassium dihydrogen phosphate and Plant phenols +Amino oligosaccharides + Potassium dihydrogen phosphate had a significant control effects against potato virus Y and weather fleck of tobacco Bina No.1.Application by spraying the inducer could improve tobacco growth and agronomic traits,as well as increase relative content of chlorophyll in tobacco leaf and disease resistance.
