有机肥不同施用量对烤烟产质量的影响

Effects of different application rates of organic fertilizer on yield and quality of flue-cured tobacco

采用田间试验及数学统计法描述的方法,研究不同有机肥用量对烤烟生长农艺性状、产质量、烟叶化学成分、中上等烟比例、土壤肥力的影响。结果表明,施用有机肥能促进烤烟生长发育,显著提高烟叶化学成分、烟叶单位面积产值、均价、中上等烟比例,同时也提高土壤养分、土壤有机质含量。烤烟种植中,合理施用有机肥,提升烟叶质量,实现烟叶高质量发展。

Field experiments and methods described by mathematical statistics were used to study the effects of different amounts of organic fertilizer on the growth and agronomic characteristics of flue-cured tobacco,yield and quality,the chemical composition of tobacco leaves,the proportion of upper and middle-class tobacco,and soil fertility.The results show that the application of organic fertilizer can promote the growth and development of flue-cured tobacco,significantly increase the chemical composition of tobacco leaf,tobacco leaf output value per mu,average price,and the proportion of upper-medium tobacco,as well as soil nutrient and soil organic matter content.In the planting of flue-cured tobacco,rationally apply organic fertilizers to improve the quality of tobacco leaves and achieve high-quality tobacco development.
