摘要
以云烟87为参试品种,采用密度和留叶数2因素裂区设计,研究了种植密度和留叶数对烤烟农艺性状及化学成分的影响。结果表明:密度及留叶数对单叶重、产量、产值、中上等烟比例均有显著影响,但密度和留叶数对单叶重、产量的互作效应不显著,而对产值、中上等烟比例的互作效应极显著;密度及留叶数对烤烟的化学成分影响较大,随着密度的增加,总氮、蛋白质、烟碱含量递减,而总糖和氯的含量则递增;随着留叶数的增加,总氮、烟碱、钾含量递减,而总糖含量增加;密度与留叶数对总氮、蛋白质和烟碱的互作效应极显著。在本试验条件下,密度为1 hm213 500株、每株留22片叶的群体结构较为合理,其烟叶品质较好。
The flue-cured tobacco variety Yunyan87 was selected to study the effect of different plant densities and remained leaves number on the agronomic traits and the chemical composition of flue-cured tobacco by a field split block experiment design.The results indicated that the plant density and the remained leavers number had a significant impact on the single-leaf weight,yield,output and the above-average leaves percentage of flue-cured tobacco,but the interactive effect of the plant density and the remained leaves number on the output and the above-average leaves proportion of flue-cured tobacco was highly significant.The total nitrogen,protein and nicotine content of flue-cured tobacco were decreased with the increase of plant density,but the total sugar and the chlorine content were increased.The total nitrogen,the nicotine content and the potassium content were decreased with the increase of remained leaves number,but the total sugar content was increased.Moreover,the interactive effect of the plant density and the remained leaves number on the total nitrogen,the protein and the nicotine content was highly significant.The group structures for the treatment of 13 500 plants per hm^2 and 22 leaves per plant was reasonable and the quality of the flue-cured tobacco was better.
