摘要
通过田间小区试验,采用随机区组设计,在本试验条件下,初步研究了不同饼肥用量和氮素形态配比对烤烟产质量的影响。方差分析结果表明:不施用饼肥,硝态氮:铵态氮=1:1的处理组合对提高烟叶亩产量、亩产值、上等烟比例、均价以及烟叶品质有显著作用,并出现随着饼肥氮用量增加,烟叶产质量反而有所下降的现象。
Under the trial conditions,a field plot trial was conducted by randomized block design in 2002 in Yunnan to study the effects of different amounts of cake fertilizer and nitrogen forms on yield and quality of flue-cured tobacco. The variance analysis result showed that the treatment of no cake fertilizer at NO3^- -N ： NH4^＋ -N = 1 ： 1 produced the highest yield,superior leaf proportions, and highest quality of flue-cured tobacco. It was also found that the tobacco yield decreased when the application amounts of the cake fertilizer increased.
