以烤烟品种云烟87为材料,分别在衡阳和永州烟区进行大田试验,研究肥料增效剂对烤烟生长发育与经济性状的影响.结果表明,肥料增效剂使衡阳烟区烤烟的生育期发生了1～2 d的变化,但对永州烟区的影响不明显;肥料减量10％+肥料增效剂的处理使烤烟的农艺性状明显改善,与对照相比,株高增高2.2～8.6 cm,有效叶片数增加0～2.0片,最大叶面积增加28～47 cm2,茎围增粗0.12～0.70 cm,但肥料减量15％和20％时优势不明显;使用肥料增效剂对烤烟各经济性状指标有明显的影响,且在衡阳和永州之间表现出了一定的地区间差异,但均以肥料减量10％+肥料增效剂处理的增产增效效果最好,与对照相比,产量提高155.8～301.5 kg...

The effect of fertilizer synergist on growth and economic characters of flue-cured tobacco were studied in Hengyang and Yongzhou with the flue-cured tobacco variety of Yunyan87 as material.The results showed that there was no difference in growth duration among different treatments in Yongzhou,while there was 1~2 d difference among treatments in Hengyang.Under adding fertilizer synergist condition,agronomic traits of flue-cured tobacco in treatment of decreasing 10% fertilizer were clearly improved,while the advantages was not clear in treatments of decreasing 15% and 20% fertilizer.Economic t...
