摘要
通过云南红壤旱地上2年的试验,研究等氮量条件下化肥绿肥配施对烟草产量质量的影响。结果表明,在施氮90 kg/hm2条件下,种植绿肥光叶紫花苕子并翻压鲜草替代15%~60%的化肥氮,烟草株高、叶片大小等生物学性状和烤烟产量质量均有改善趋势。烤烟产量随着绿肥氮所占比例的增加而增加,上中等烟叶产量以绿肥替代30%化肥氮最高,为1 863.1 kg/hm2,上中等烟叶产值以绿肥替代15%化肥氮最高,为25 342.25元/hm2。
The field experiments were conducted on combining application of chemical nitrogen fertilizer and fresh vetch straw on tobacco under equal nitrogen rates in red soil of upland in Fuyuan County from 2008 to 2009,where vetch（Vicia villosa Roth var.） had been planted as previous crop.Results showed that combining application of fresh vetch straw and chemical nitrogen fertilizer was advantage to improving the biological traits of tobacco,such as length and width of leaves,plant height,stem perimeter of upper leaves harvesting period.Yield of flue-cured tobacco leaves was increased while raising proportion of nitrogen from green manure replacing nitrogen of chemical fertilizer,1863.1 kg/hm2 of the highest yield of high-middle-quality flue-cured tobacco leaves was obtained when 30 % of chemical nitrogen fertilizer had been replaced by nitrogen from green manure,and 25 342.25 Yuan/hm2 of the highest output value of high-middle-quality flue-cured tobacco leaves was received when 15 % of chemical nitrogen fertilizer had been replaced by nitrogen from green manure.
