摘要：

为探索‘中烟103’在攀枝花市烟区合理的种植模式，以3种种植密度和3种单株留叶数为变量，采用双因素的随机区组设计，研究了密度和留叶数对烤烟生长、叶面积、叶干重、产量、产值和中上等烟率的影响。结果表明，随着密度增加，单叶重显著降低，下部和中部的叶面积增大，产量和产值提高，但上等烟率下降，中上等烟率无显著变化；随着留叶数的增加，上部烟叶长宽显著降低，当留叶数为20片时，产值、产量、上等烟率和中上等烟率最高。总体分析，在本试验条件下，行株距为(1.2 m×0.5 m)~ (1.2 m×0.4 m)，留叶数为20片的种植模式较为合理，中上等烟率最高，达到优质适产。

Abstract: Experiment on flue-cured tobacco variety ‘Zhongyan 103’ was carried out in Panzhihua Area for the aim of researching the suitable planting patterns of this variety. Two factors random configuration design was used to study the effect of 3 planting densities and 3 kinds of leaves-keeping number of this variety on biological yield and output value. The effect on plant growing, area, dry weight of leaves was also studied. The results showed that the individual weight of leaves significantly reduced with the density increase. Leaves area of lower and middle part of plant increased, yield and output value increased in this case, but superior rate declined, there was no significant change on medium to superior rate in this case. The length and width of upper part leaves reduced significantly with the leaves-keeping number increase. When leaves-keeping number was 20 pieces, it could have the highest yield and output value, the highest rate of superior and medium to superior level’s production. In general, the planting pattern of planting distance at scope from (1.2 m× 0.5 m) to (1.2 m× 0.4 m) with leaves-keeping-number of 20 pieces was the appropriate condition under this experiment, it could get the highest rate of middle to superior, could harvest good quality and suitable yield tobacco.
