不同种植密度对烤烟产质量的影响
|
摘要
设计不同种植密度试验,综合对比分析了烤烟大田生育期、农艺性状、病害情况、经济性状、常规化学成分等指标。结果表明,移栽间距55 cm的处理生育期增长,株高、节距、叶面积等农艺性状表现较好,产值较高;移栽间距45 cm的处理化学成分较协调,感官评价质量表现较好。不同种植密度可以影响叶片组织结构的发育特征,协调烟叶内部化学成分含量,最终达到改良烤烟品质的目标。
The growth period, agronomic traits, disease situation, economic traits and conventional chemical components of flue-cured tobacco were comprehensively compared and analyzed through different planting density experiments. The results showed that the treatment with 55 cm transplanting spacing had better growth period, plant height, pitch, leaf area and other agronomic traits, and higher output value. The chemical composition of 45 cm distance between transplants was more coordinated, and the quality of sensory evaluation was better. Different planting densities can affect the development characteristics of leaf tissue structure, coordinate the content of chemical components in tobacco leaves, and ultimately achieve the goal of improving the quality of flue-cured tobacco.
