摘要
【目的】探索不同螯合肥联合施用对烤烟烟叶品质的影响.【方法】采用盆栽和田间试验,研究了烤烟联合施用不同螯合肥烟叶化学成分含量变化,并对不同处理烤烟烟叶的总糖、还原性糖、总氮、烟碱、钾等化学成分含量变化进行综合分析.运用统计学中的主成分分析法,综合比较分析康凯Ⅱ号、富诺根与富诺钾和康凯Ⅱ号、富诺根与富诺磷联合施用对烤烟烟叶品质的影响.【结果和结论】盆栽试验表明,苗期叶面喷施康凯Ⅱ号和富诺根,生长期分别喷施富诺钾或富诺磷,烤烟烟叶烟碱含量分别降低41.24%和3.44%,钾含量分别增加42.86%和26.02%.田间试验表明,联合施用康凯Ⅱ号、富诺根和富诺钾或富诺磷,烤烟烟叶钾含量分别增加56.00%和93.28%,烟碱含量分别降低23.11%和29.25%.
[Objective] To improve the quality of the flue-cured tobacco leaf by combined application of chelated fertilizer .[Method]Effects of combined application of chelated fertilizer on the contents of total sugar, reducing sugar , total nitrogen, nicotine and potassium of flue-cured tobacco leaf were studied u-sing the pot and field experiments .Effects of chelated fertilizer of Kangkai Ⅱ, Funuogen , Funuo potassi-um or Funuo phosphorus on the quality of tobacco leaf were analysed .[Result and conclusion]The re-sults showed that in plot experiments , application of Kangkai Ⅱand Funuogen at the stage of seedling , Funuo potassium or Funuo phosphorus at the stage of growing reduced the contents of tobacco leaf nicotine by 42.86%and 26.02%and increased the potassium contents by 41.24%and 3.44%.In field experi-ments, The combined application of Kangkai Ⅱ, Funuogen, Funuo potassium or Funuo phosphorus re-duced the contents of tobacco leaf nicotine by 56.00% and 93.28%, increasing the potassium contents by 23.11%and 29.25%,respectively .
