摘　　要：为探明遮荫处理对烟叶生产的影响,2012年在湖南省邵阳市烟田中部叶采收后,对烟株上部叶进行人工遮荫处理,结果表明,晴天14:00,普通白色棉纱布遮荫处理,田间光照强度降低45 666 Lux,温度降低2.8℃,消除了高温逼熟现象,改善了上部叶的田间成熟度。通过人工遮荫,烤后烟叶的上等烟比例提高3.56%,烟叶质量得到改善。In order to study the impact of shading treatment on the tobacco production, field experiment was carried in Shaoyang in 2012. The results showed that when the tobacco plants were shaded by white organdie, the illumination inten-sity at 14 o＇clock on sunny day reduced by 45 666 Lux, and the temperature of the field decreased by 2.8℃,which resul-ted in the improvement of the maturity of upper leaves. The high class leaf proportion was increased by 3.56%, and leaf quality was improved.
