复合生物有机肥在烤烟生产中的应用研究

Response of flue-cured tobacco to compound bio-organic fertilizer

通过盆栽试验和田间试验,研究复合生物有机肥对烤烟生长发育以及产量、品质的影响。结果表明,适量的复合生物有机肥与化肥配合施用效果明显优于单纯施用化肥,不仅可以促进烟株生长发育,增强抗病力,而且有效地提高了烟叶含钾量和干物质积累量,产量、质量都有较大幅度提高,经济效益显著。

Pot and field experiments were conducted to study the effects of compound bio-organic fertilizer on the growth, yield and quality of flue-cured tobacco. The results indicated that appropriate combined application of bio-organic fertilizer with chemical fertilizer was better than that of application of chemical fertilizer. The effect could not only promote the growth and development of plant, enhance its resistance to disease, but also increase dry matter accumulation and potassium content in leaf, remarkably improve the yield and quality. The economic benefit was significant.
