摘要
试验结果表明,生物有机粒肥具有提高烤烟产量,增加单叶重量,增大单叶面积和厚度的作用,还可提高烟叶含糖量,相对降低总氮和烟碱含量,使烟叶中主要化学成分之间的比例关系趋于协调,品质得到改善。
The testing results showed that the effects of earthworm fecal pellet manure on cured tobacco include;increasing tobacco yields;raising weight,area and thickness of single leaf Improving carbohydrate contents and decreasing total N and nicotine in the leaves thereby to coordinate the ratio among the major chemical compositions of tobacco leaves and to improve their qualities.
