| 摘 要： | 通过 3年定位点试验研究 ,结果表明 :烤烟连作后烟株的田间长势 ,烟叶的产量、产值、均价、上中等烟比例均明显下降。连作对烟叶内在质量也产生影响 ,但对内在质量的影响滞后于对烟株生长、产量、产值的影响。 3种连作田的改良措施成效不大 |
| 关 键 词： | 烤烟 连作 产量 烟叶内在质量 |

| Abstract: | year fixed|site field trial was conducted to study the influence of continuous cropping on the yield and quality of flue|cured tobacco. The results showed that 1) the growth vigor of tobacco plant, yield, output value, average price, and the proportion of the superior and medium tobacco leaves after continuous cropping were significantly decreased; 2) while continuous cropping had negative effect on chemical components and smoking quality of tobacco, the effect lagged behind that on the growth of tobacco plant, yield and output value; and 3) the 3 tested measures had little effect on improving the continuous cropped field. |
| Keywords: | Flue|cured tobacco Continuous cropping Yield Quality |
