[目的]为烤烟的安全生产提供一定的科学依据。[方法]通过大田试验,研究了有机-无机肥配施条件下一次性拌塘施肥、一次性环形施肥、分次施肥与常规施肥方式对烟株农艺性状、烟叶产量、物理性状、化学成分及感官评吸质量的影响。[结果]环形施肥更利于烟苗的早发快长,提前进入团棵期;在旺长期和采烤前农艺性状无明显差异,但较常规而言,拌塘、环形和分次施肥肥效发挥较缓慢;物理性状以分次施肥效果最好;烟叶产质量、化学成分、感官评吸质量均以环形施肥处理为优。[结论]环形施肥方式较适合优质烤烟的生产要求。
[Objective] The research aimed to provide scientific basis for the safety of flue-cured tobacco. [Method] The field experiment was conducted to study the agronomic characteristics, yield, physical properties, chemical composition and chemical composition of tobacco plants under the conditions of organic-inorganic fertilizers application with one-time mixing of ponds, one-time annular fertilization, Sensory evaluation of the quality of the impact. [Result] The ring fertilization was more beneficial to the earlier and faster growth of tobacco seedlings, and earlier entered the soil and fructification stage. There was no significant difference in the agronomic traits before and after harvesting. However, compared with conventional practice, Slowed down. The physical fertilization was the best in different times. The quality of tobacco leaf, the chemical composition and the quality of sensory evaluation were all excellent. [Conclusion] The annular fertilization method is more suitable for the production requirements of high quality flue-cured tobacco.
