烟草专用肥与不同有机肥配施对烤烟生长及主要化学成分的影响

Effects of spcialty fertilizer combined with different organic manure fertilizers on growth and quality of flue-cured tobacco

采用田间试验,研究了发酵血粉、腐熟菜籽饼肥与烟草专用肥配施对烤烟生长发育、化学品质及致病性的影响.结果表明:在烟草专用肥中配施部分发酵血粉和腐熟菜籽饼肥代替氮素化肥能增强烤烟的生长势,使烤烟生育期延长,产量增加;不同肥料处理对烤烟的致病性、物理指标和化学成分含量影响差异显著,以腐熟的菜籽饼肥效果最好,烟草专用肥次之,发酵血粉的效果最差,主要表现在叶片肥厚,含梗率高,耐熟性差,发病率高,密度小,烟碱含量高而糖含量低等.

The field experiment was done to investigate the growth, quality and pathogenicity of flue-cured tobacco by applying different types of organic fertilizer combined with specialty fertilizer. The results indicated that, swine blood fermentation and rapeseed cake fertilizer could enhance the growth tendency, lengthen the growing period, increase the output. The effects of different fertilizers on pathogenicity, physical target and chemical composition was diverse. Rapeseed cake fertilizer is obviously better than swine blood fermentation and CK. Swine blood fermentation＇s result is worst. It showed that the flue-cured tobacco have many problems, such as thick leaf, higher stem ratio, higher disease infected, worse maturation tolerance, small density of leaf, high content of nicotine but low content of sugar.
