水溶性追肥配施促根剂对烤烟产量和质量的影响

为提高稻茬烤烟产质量，以云烟87为材料，采用双因素试验，设计施用促根剂（地康食安1号、诱抗特、普多收魔力根）和追肥模式（传统追肥、水溶性追肥），研究了促根剂、水溶性追肥及其互作对烤烟经济性状、外观质量、物理特性、化学成分、评吸质量的影响。结果表明，施用水溶性追肥配施促根剂，有利于提高烟叶产量8.41%～28.53%、产值12.29%～36.88%、上等烟率2.55%～10.63%，改善烟叶外观质量和物理特性，提高烟叶化学成分协调性，提高烟叶评吸质量，提高上部叶评吸总分6.05%～8.54%，中部叶7.89%～9.78%，下部叶4.58%～8.74%，可增糖增钾，但上部烟叶烟碱含量增加，综合以水溶性追肥配施“地康食安1号”、“诱抗特”综合效益最佳，且在实际生产中具有一定推广价值。

Effects of water-soluble topdressing with root-promoting agents on the quality of flue-cured tobacco production

In order to improve the quality and yield of tobacco leaf production, a two-factor test was conducted to investigate the effects of root promoters, water-soluble topdressing agents and their interactions on the economic characters, appearance quality, physical properties, chemical composition and evaluation quality of flue-cured tobacco, using Yunnan Tobacco 87 as the material and designing the application of root promoters (Dikang Shi''an No.1, Youkangte, and Puduoshou) and topdressing mode (traditional topdressing, water-soluble topdressing).The results showed that the application of water-soluble topdressing with the application of root promoters was conducive to boosting the yield by 8.41%-28.53%, output value by 12.29%-36.88% and upper smoking rate of tobacco leaves by 2.55%-10.63%, improving the appearance quality and physical characteristics of tobacco leaves, and the coordination of tobacco chemical composition, improving the quality of tobacco leaf evaluation, increasing the integrated score of smoking in B2F by 6.05%-8.54%, C3F by 7.89%-9.78%, X2F by 4.58%-8.74%, increasing sugar and potassium, but the upper tobacco leaf nicotine content was also increased, and the comprehensive benefit of water-soluble topdressing with "Dikang Food Safety No. 1" and "Temptation Resistance Special" was the best, and had certain promotion values in the actual production.
