摘 要:为探讨烤烟适宜的施氯量,研究了不同施氯量对烤烟生长和品质的影响。结果表明,施氯量为45 kg/hm2时烤烟株高增加率极显著高于其他处理,施氯量为30 kg/hm2时烤烟最大叶面积和叶宽增加率显著高于其他处理;总糖含量和两糖差随施氯增加而升高,施氯后各处理烟叶总氮含量均显著低于对照组,且烟碱含量呈降低趋势;施氯量在30~45 kg/hm2时能有效促进烟叶生长发育,叶绿素既能大量合成也能在后期充分降解,降低烟叶含氮化合物含量,抑制烟碱合成,增加烟叶含糖量,有利于提高烟叶评吸质量。The effects of chlorine application rates on growth, yield, and quality of flue-cured tobacco were studied in order to investigate the appropriate chlorine application rate. The results showed that when chlorine application rate was 45 kg/ha, the increase rate of tobacco height was significantly (P〈0.01) higher than the other treatment. The increase rate of leaf area and width were significantly (P〈0.05) higher than other treatment when the chlorine application rate was 30 kg/hm2, the sugar content and TS-RS increased with increasing chlorine rates, the leaf total nitrogen content decreased if chlorine applied (P〈0.05), and after apply chlorine, the nicotine content reduced. When chlorine rate were between 30-45 kg/ha, it could increase tobacco growth and reduce the N compounds of tobacco leaf and inhibit the nicotine production. With this range the chlorophyll could compound in the early and disintegrate in the late. At the same time it could increase the sugar content, and helped to significantly improve smoking quality of tobacco.
