摘要
在南雄烟区进行了施肥方法对烤烟生长发育及产、质量的影响试验。结果表明:烟苗生长发育前期施足基肥,在旺长-圆顶期追肥时,将钾肥分次兑水淋施能平衡烟株对营养的吸收,促进烟株生长发育和上部叶的开片,提高烟叶的产、质量及可用性。在南雄烟区烤烟以70%烟草专用肥作基肥在移栽时施入,30%烟草专用肥作追肥在大培土时施入,100%硝酸钾作追肥在旺长-圆顶期分3次兑水淋施的施肥方法效果最佳。
The effects of method of fertilizer application on the growth, development, yield and quality of flue-cured tobacco were studied in Nanxiong tobacco growing areas. The results showed that sufficient base fertilizer applied at early growing stage and diluted potassium nitrate sprinkled for several times at fast growing and round top stages could balance the nutrition absorption of tobacco plants, promote the growth and development of tobacco plants and the opening of upper leaves, and improve the yield, quality and usability of tobacco leaves. In Nanxiong tobacco growing areas, the best method of fertilizer application was： 70% tobacco specialty fertilizer as base fertilizer applied while transplanting, 30% tobacco specialty fertilizer applied while earthing up, all potassium nitrate diluted and sprinkled separately for 3 times during fast growing period.
