Abstract: 为探索发展低碳烟草农业、构建资源节约型和环境友好型农业,促进特色烟叶开发和烟叶产业的可持续发展,通过田间试验,以绿肥黑麦草不同翻压量为基础,具体研究了翻压绿肥对烤烟大田生长及烤后烟产量和产值效益的影响。结果表明,烟田翻压绿肥能够明显调节烟株大田期的生长发育,促进烟株对矿质元素吸收、利用和储存。从烟株生长发育综合指标来看,以翻压量在22500~30000 kg/hm2时烟株生长较好,单株干物质积累、单株氮、磷、钾积累量最高。与对照相比,单株干物质积累量、单株氮、磷、钾积累量量最高增幅分别为19.84%、59.34%、34.94%、43.55%;同时,翻压绿肥能够明显提升烤后烟叶产量和产值效益相关指标,上中等烟比例、产量和产值最高分别增加16.13%、203.56 kg/hm2、3519.01元/hm2。 Field experiments were conducted to study low-carbon agriculture and build resource-saving, environment-friendly agriculture and promote the tobacco agriculture sustainable development and the production of tobacco leaves with specific characteristics. The experiments were based on different green manure application rates (7500, 15000, 22500, 30000 kg/hm2) to study the effects of ploughing ryegrass under soil on growth and development, yield and output value of flue-cured tobacco. The results showed that returning green manure could obviously regulate the growth and development of flue-cured tobacco, and promote the absorption, using and storage of mineral element by tobacco plants. The comprehensive index of the treatments returning green manure 22500-30000 kg/hm2 were better than others. In comparison with the control, the largest increase amplitude of dry matter accumulation, N accumulation, P accumulation, K accumulation per plant were 19.84%, 59.34%, 34.94%, 43.55% respectively. At the same time, returning green manure could obviously improve the related indexes of yield and output value, the largest increase amplitude of high and middle quality tobacco leaves, yield and output value were 16.13%, 203.56 kg/hm2, 3519.01 yuan/hm2 respectively.
