| 摘 要： | 在黑钙土自然肥力下,研究了重茬栽培对烤烟磷积累及分配的影响。结果表明:随着重茬年数的增加,收获时根系、下部叶、中部叶和上部叶内的磷积累量均呈下降趋势;重茬3年有利于磷在茎内的积累,但是重茬5年不利于磷在茎内的积累;重茬5年会使根系、中部叶内磷的分配比例增加,而使茎、下部叶和上部叶内磷的分配比例下降。综合分析认为,烤烟重茬栽培年限不宜超过5年。 |

| Abstract: | The phosphorus accumulation and distribution law in the continuously-cropped flue-cured tobacco under the condition of chernozem natural fertility were studied.The phosphorus accumulation in root system,lower leaves,middle leaves and upper leaves all showed a decreasing trend in harvest time when the continuous cropping years increased.The 3-year continuous cropping was beneficial to the phosphorus accumulation in stem,but the 5-year continuous cropping was not beneficial to it.The continuous cropping for 5 years increased the distribution proportion of phosphorous in root system and middle leaves,while decreased that in stem,lower leaves and upper leaves.Comprehensive analysis indicated that the continuous cropping of flue-cured tobacco should not exceed 5 years. |
