摘要
为改良土壤,提高烟叶质量,实现烟叶生产可持续发展,采用田间试验的方法,研究了不同有机物料(普通商品有机肥、生物有机肥、生物质炭)与化肥配施对土壤改良和烤烟产质量的影响。结果表明:与常规施肥(100%化肥)相比,有机物料与化肥配施能够提高土壤酶活性、微生物多样性、烤后烟叶含钾量,促进烟叶化学成分更为协调,从而能够提高烟叶均价、上等烟比例和经济效益,其中以生物质炭与生物有机肥联合施用的效果最佳。
A field experiment was conducted to study the application effects of different organic materials（including conventional commercial organic fertilizer, bio-organic fertilizer and biochar） on soil improvement and flue-cured tobacco yield and quality in order to realize the sustainability of flue-cured tobacco production. The results showed that compared with the local conventional fertilization（100% chemical fertilizer）, the combination of organic materials with chemical fertilizers could enhance soil enzyme activities and soil microbial functional diversity, significantly increase potassium content and improve the coordination of chemical composition of flue-cured leaves, promote average price, fine tobacco ratio and economic benefits of flue-cured leaves. Comparatively, the combined application of bio-organic fertilizer and biochar is more effective.
