摘要： 为解决罗平地区部分植烟土壤板结、粘重问题，通过掺入河沙对烟叶农艺性状、产质量及主要化学成分指标的影响试验研究了土壤改良对烤烟生长及产质量的影响。结果表明：在土质较为粘重田地上，每个烟塘施用河沙2、3、4 kg处理的农艺性状较对照和施用河沙1 kg处理的要好，烟叶产量、产值、均价、上等烟比例也明显增高；每塘施用河沙3、4 kg能提高烟叶水溶性总糖、还原糖和K2O含量，降低烟碱含量，而塘施河沙1、2 kg处理对化学成分影响不明显。

Abstract: The effects of improvement soil by application sand on growth development, yield and quality of flue-cured tobacco on the heavy clay soil were Studied. The results showed that the treatments of application sand 2 kilogram,3 kilogram,4 kilogram per plant separately on agronomic characters were better than that of application sand 1 kilogram and the control on the heavy clay soil. The yield, quality, average price and superior leaf ratio of flue-cured tobacco were increased significantly. The content of reducing sugar, total sugar and potassium were better by application sand 3 kilogram and 4 kilogram per plant separately than that of application sand 1 kilogram, 2 kilogram and the control, but the content of nicotine was decreased, but the effects of chemical composition by application sand1 kilogram,2 kilogram per plant separately were not marked.
