不同作物茬口对烟草大田农艺性状及烟草品质的影响

Impact of Different Crop Stubbles on Agronomical Characters and Quality of Tobacco

  • 摘要: 在烟草种植过程中,白菜茬、玉米茬、红薯茬和芝麻茬等茬口对烟草的品质影响较大.测定4种茬口种植烟草后的株高、茎围、叶片数、烟草叶面积、化学质量、品质等指标的差异.结果表明,红薯茬和芝麻茬烟草田间长势比较好,株高比较高,茎围粗壮,叶面积要远远高于白菜茬和玉米茬;从质量性状来看,红薯茬和芝麻茬能显著提高烟叶可溶性糖、还原糖和烟碱含量,并且能降低烟叶含氯量;从施木克值、钾氯比、氮碱比这些品质指数及产量、产值来看,烟草以红薯茬和芝麻茬较好,白菜茬次之,玉米茬最差

     

    Abstract: Chinese cabbage stubble soil,corn stubble soil, sweet potato stubble soil and sesame stubble soil showed a great influence on the quality of tobacco in its planting. Tobacco were planted in corn stubble soil, sweet potato stubble soil, sesame stubble soil and Chinese cabbage stubble soil separately.The differences of plant height, stem girth, leaf number, leaf area, matter content and quality of tobacco were determined. It was found that tobacco planted in sweet potato soil and sesame soil had better growth, higher plant, stronger stem and larger leaf than that planted in corn soil and Chinese cabbage soil. It was also also found that the tobaccos in sweet potato soil and sesame soil had more content of potassium and nicotine, but less content of chlorine ion. Considering the quality and properties, sweet potato soil and sesame soil increased the content of soluble sugar, reducing sugar and nicotine, and decreased the chlorinity. From the indices of chmuck’s value, potassium/ chlorine, nitrogen/nicotine, yield, output value, we could conclude that sweet potato stubble soil and sesame stubble soil were more suitable soil for tobacco planting, while the corn soil was more bad
