不同种植密度对烤烟产量与产值的影响研究

通过大田试验研究了烤烟在不同密度条件下对农艺性状、经济性状与产量的影响。结果表明:各处理株高、有效叶片数随种植密度的增加而升高,但增幅较小;茎粗、最大叶长、叶宽和单株叶面积均随密度的增加而下降。各处理上中等烟率、产量、产值随密度增加先升高再降低。

The Influence of Flue-cured Tobacco Production and Output in Different Density

Flue-cured tobacco was studied through field trials at different densities under the conditions of agronomic traits and economic traits, yield, the results showed that： the processing plant height, leaf number and effective with the increase of planting density increased, but a smaller increase ; stem diameter maximum leaf length leaf width and leaf area per plant were as density increases. The handling of secondary smoke, yield, production value increased with the density, the first increase and then decrease.
