-
摘要: 本研究通过田间小区试验,筛选评估了微生物菌剂LSW-4、土壤调理剂牡蛎钾、抗性诱导剂东莨菪内酯和化学药剂青枯绿及络氨铜对田间烟株生长、烟草青枯病、根结线虫病发生的影响.结果表明,LSW-4菌剂(10 kg/667 m2和5 kg/667 m2)和牡蛎钾(30 kg/667 m2)在烟苗移栽前窝施处理能有效降低田间烟草青枯病发病率和病情指数,其整体防效为29.05%, 23.34%和23.66%,最高防效分别为71.43%, 47.62%和59.77%;同时,牡蛎钾处理能有效降低田间烟草根结线虫病的发生,相对防效达44.32%.本研究旨在探索烟草青枯病和根结线虫病的有效防控手段,为青枯病和根结线虫病的绿色、系统防控提供参考,为烟区高质量烟叶发展提供支撑.Abstract: In this study, the effects of microbial agent LSW-4, soil conditioning agent oyster potassium, resistance inducer scopolamine and chemical agents Qing-Ku-Lv and Cupric-Amminium Complexion on the growth of tobacco, the control of tobacco bacterial wilt and root-knot nematode in the field were evaluated through the field experiment. The results showed that, LSW-4(10 kg/667 m2和5 kg/667 m2) and oyster potassium(30 kg/667 m2) could effectively reduce the incidence and disease index of tobacco bacterial wilt in the field, the comprehensive control efficiency were 29.05%, 23.34% and 23.66%, and the highest control efficiency was 71.43%, 47.62% and 59.77%, respectively. Meanwhile, oyster potassium treatment could effectively reduce the incidence and disease index of tobacco root-knot nematode disease in the field with a relative control effect of 44.32%. The aim of this study was to explore the effective control methods of tobacco bacterial wilt and root-knot nematode disease to provide reference for the green and systematic control of tobacco wilt and root-knot nematode disease, and support for the development of high-quality tobacco leaves.
