摘要：

通通过大田试验和室内分析相结合，研究不同施肥措施对烤烟养分吸收和干物质积累的影响。结果表明，不同施肥措施均能明显提高烟株的大田长势，促进烟株对氮磷钾等矿质元素的吸收和根茎叶干物质的积累，提高肥料的利用效果。与对照相比，T1处理的综合效果最好，说明打大窝带肥移栽技术更能够促进烟株早生快发，符合烟株“氮素前移，钾素后移”的生长需求规律。

Abstract:

Field experiments combined with laboratory analysis were conducted to study the effects of different fertilizer application measures to nutrient absorption and dry matter accumulation of tobacco, The results showed that, different fertilization measures could significantly enhance the field of tobacco plant growing, to promote tobacco plants such as mineral elements of NPK the absorption and rhizome whereas material accumulation, compared with the control, big pit transplanting with fertilizer to play with the best use of fertilizer, consistent with tobacco, “N forward, backward K” law of demand growth.
