| 摘 要： | 为研究移栽灵对烟草作物抗病抗逆性的影响,在贵州3个不同生态区进行了药效试验.结果表明,移栽灵控制烟草苗期立枯病防效可达100%;明显推迟烟草黑胫病始发期(较对照晚20d以上)和减缓发病速率,防效达80%以上,药效稳定,持效期长.同时,施用移栽灵后,烟苗根系数量或根干重明显增加,地上部生长发育优于对照,具有显著的促根壮苗作用.

| Abstract: | The efficacy test of Yizailing was carried out in three different ecology areas of Guizhou to study its effect on disease and stress resistance of tobacco.The results show that Yizailing could control seedling blight completely in seedling stage,obviously postpone emerging stage of black shank(be late more than 20 days comparing to CK) and reduce speed of the disease.With steady effect and long persistent period,the control effect of Yizailing on black shank is above 80%.The quantity and dry weight of tobac... |
