2010-2011年采用大田试验,研究了施用腐植酸肥对百色植烟土壤养分和烤烟香气质量的影响。结果表明,施用腐植酸肥可提高土壤速效钾、有机质等主要养分含量,并能明显提高烤烟的经济效益,以腐植酸肥用量为150 kg/hm~2的烤烟经济性状指标最高。施用腐植酸肥能改善烟叶
Field experiments were conducted in 2010-2011 to study the effects of humic acid fertilizer on soil nutrient and tobacco aroma quality in Baise tobacco planting. The results showed that the application of humic acid fertilizer could increase the main nutrient contents such as available potassium and organic matter in soil and increase the economic benefits of flue-cured tobacco significantly. The economic index of flue-cured tobacco with humic acid fertilizer dosage of 150 kg / hm ~ 2 was the highest. Applying humic acid fertilizer can improve tobacco leaf
