| 摘 要： | 通过打除烤烟田间不适用鲜烟叶,研究3种田间打叶方式对烤烟农艺性状和病害的影响。结果表明,与对照相比,打掉底部2片叶、顶部2片叶,可以促进留存叶片的生长,增加叶片长度和宽度;打叶处理减轻了病害的发生,赤星病、青枯病、黑胫病的发病率和病情指数都有所下降。建议生产上在烟株打顶后适时打掉底部2片叶,以促进叶片开展,减少病害危害。

| Abstract: | By removing unusable fresh tobacco leaves, the effects of three kinds of removing leaf methods on agronomic characteristics and diseases of flue-cured tobacco were studied. The results showed that, compared with the contrast, when removing the bottom two leaves and the top two leaves, the growth of the other retained leaves were promoted, and the length and width of the retained leaves were all greater than that of the contrast. The results also showed that removing unus-able fresh leaves could reduce the occurrence of the disease. The disease incidence and disease index of tobacco brown spot, granville wilt and black shank disease all decreased. It was suggested that removing two bottom leaves was practical to in-crease the leaves growth and reduce disease hazards. |
