| 中文摘要: |
| 试验在田间条件下，研究了纯化肥氮（对照），50%大豆饼肥氮与50%化肥氮，100%大豆饼肥氮3个处理对烤烟总氮、茎、下、中、上部叶氮积累的影响及对以上3个部位烟叶氮含量及产值的影响规律。小区试验设计，3次重复。结果表明：生育前期3个处理氮积累量无显著差异，收获后100%饼肥处理氮积累量显著高于对照；茎内氮积累量100%饼肥处理比对照提高1.16 kg/hm2，50%饼肥处理降低0.06 kg/hm2；下部叶100%饼肥处理比对照提高5.30 kg/hm2，50%饼肥处理仅提高1.34 kg/hm2；上部叶100%饼肥处理显著高于对照；烟叶含氮量随着生育期延后而降低，对照上部叶含氮量最高，饼肥处理下部叶含氮量最高；50%饼肥处理产值高达56 278.50元/hm2，上等烟比例达到57.57%，显著高于其他两个处理。综合分析认为，生产中大豆饼肥施用比例以50%～100%为佳。 |

| In order to study the effect of fermented soybean cake on nitrogen accumulation and output value of tobacco leaves, through field experiment with plot design and three replications, the total nitrogen, nitrogen accumulation changes, the nitrogen content in stem, lower leaf, middle leaf and upper leaf, and the output value under 3 treatments: pure inorganic fertilizer (control), 50% the fermented soybean cake and 50% inorganic fertilizer, 100% fermented soybean cake, were examined. The results showed that there was no significant difference of nitrogen ac
cumulation between the 3 treatments in nearly growth stage. After the harvest, nitrogen accumulation in treatment 100% fermented soybean cake was significantly higher than that in control. Nitrogen accumulation of stem in treatment 100% fer
mented soybean cake was 1.16 kg/hm2 higher than control, and decreased by 0.06 kg/hm2 in treatment 50% fermented soybean cake. Nitrogen accumulation of lower leaves increased by 5.30 kg/hm2 in treatment 100% fermented soybean cake and only by 1.34 kg/hm2 in treatment 50% fermented soybean cake. Nitrogen accumulation of upper leaves in treatment 100% fermented soybean cake was significantly higher than the control. Nitrogen content of tobacco leaf reduced with the delay of the growth period. In the control, the nitrogen content of upper leaves was highest, but in treatment 100% fermented soybean cake, the nitrogen content of lower leaves was highest; In treatment 50% fermented soybean cake, the output value reached 56 278.50 yuan/hm2, and superior tobacco proportion reached 57.57%, which were significantly higher than the other two treatments. Based on a comprehensive analysis, an application ratio of fermented soybean cake in 50%～100%
was the best in the production. |
