摘要
研究了绿肥掩青对烤烟土壤酶活性、微生物数量和烟叶致香成分含量的影响。结果表明,绿肥掩青能够提高土壤酶活性,提高土壤微生物数量,显著提高土壤的根系活力,提高烟叶香气成分的含量。因此,绿肥掩青能够很好地改良土壤,改善烟叶质量。
The effects of green-fertilizer covered on the soil enzyme activity, microbial quantity and the content of aroma components of flue- cured tobacco were studied. The results showed that green-fertilizer covered increased soil enzyme activity and the number of microorganisms, significantly improved the root activity of soil, and improved the content of aroma components in tobacco leaves. So green-fertilizer covered could modify soil and improve the quality of tobacco leaf.
