有机菌肥与水溶性肥料配施对植烟土壤及烤烟品质的影响

Effects of Combined Application of Organic Bacterial Fertilizer and Water-soluble Fertilizer on Tobacco-planting Soil and Flue-cured Tobacco Quality

探讨了微生物菌肥和水溶性肥料配施对土壤理化性状和烤烟产质量的影响,以当地主栽品种云烟87为试验材料,研究了土壤理化性质、土壤酶活性、烟叶农艺性状、烤后烟物理特性及香气成分和经济性状的差异。结果表明:与常规施肥的对照相比,微生物菌肥和水溶性肥料配施后,土壤理化性状得到有效改善,土壤酶活性显著提高,烟株中后期农艺性状显著改善,烤烟生长发育良好,烤后烟叶的经济性状和品质得到显著提高,整体上以T_3处理的水溶性肥料的效果最好。

Taking the mainly-cultivated flue-cured tobacco variety ＂Yunyan 87＂as experimental material,the author explored the effects of combined application of organic bacterial fertilizer and water-soluble fertilizer on the physicochemical properties and enzymatic activity of tobacco-planting soil,the agronomical characters of tobacco plants,as well as the physical characteristics,aroma components,economic traits,yield and quality of baked tobacco leaves. The results showed that： in comparison with the control（ conventional fertilization）,the combined application of organic bacterial fertilizer and water-soluble fertilizer effectively improved the physicochemical properties of tobacco-planting soil,significantly enhanced the soil enzymatic activity,significantly improved the agronomical characters of tobacco plants at middle and later growth stage,promoted the growth and development of tobacco plants,and significantly improved the economic traits and quality of baked tobacco leaves. In summary,the water-soluble fertilizer in T3 treatment had the best effects as a whole.
