摘要
采用全生育期水培试验研究 Ｃｌ对烤烟光合作用的影响．结果表明，适量施 Ｃｌ可促进烟叶叶绿素合成，提高净光合速率和光饱和点，降低光补偿点，缓和“午休”现象，从而提高烤烟整体的光合效率，提高烟叶产量．缺 Ｃｌ和过量施 Ｃｌ都显著影响烤烟的光合作用，但表现出不同的规律性．
Hydroponics in the full growth season was used to detect the effcet of chloride on photosynthesis of tobacco. The results showed that rational chloride level could improve chlorophyll synthesis, enhance net photosynthetic rate and light saturation point, lower light compensation point and control the phenomenon of noon nap, so that photosynthetic efficiency and yield of tobacco were increased. On the other hand, photosynthesis of tobacco was seriously inhibited under the condition of deficient or excessive chloride, but different regularities were performed.
