不同施硫量和硫素营养水平土壤对烟叶质量的影响

Effects of different sulfur application rates and sulfur nutrient levels on the quality of tobacco leaves in soil

为研究不同硫肥施用量和硫素营养水平土壤对烟叶质量的影响,在含硫量>25、10~20和<10 mg/kg的土壤上分别施用0、30、60和90 kg/hm^(2)的硫肥,分析比较不同处理烟叶质量的差异,包括外观质量、硫酸根离子含量和感官质量等方面。结果表明,施硫量过多不利于烟叶的外观质量和感官质量,且可能导致成品卷烟烟丝的硫酸根离子含量偏高。为了兼顾外观质量、化学成分和感官质量,施硫量不应超过60 kg/hm^(2),如果植烟土壤硫素营养水平超过25 mg/kg,施硫量应不超过30 kg/hm^(2)。研究可为烟叶产区和卷烟工业企业合理施用硫肥、有效控制烟叶含硫量提供参考。

To study the effects of different sulfur fertilizer application rates and sulfur nutrient levels on the quality of tobacco leaves in soil,sulfur fertilizers of 0,30,60,and 90 kg/hm^(2) were applied to soils with sulfur content>25,10-20,and<10 mg/kg,respectively.The differences in tobacco leaf quality among different treatments were analyzed and compared,including appearance quality,sulfate ion content,and sensory quality.The results indicated that excessive sulfur application was not conducive to the appearance and sensory quality of tobacco leaves,and may lead to a higher sulfate ion content in the finished cigarette tobacco.In order to balance appearance quality,chemical composition,and sensory quality,the sulfur application rate should not exceed 60 kg/hm^(2).If the sulfur nutrient level of tobacco planting soil exceeded 25 mg/kg,the sulfur application rate should not exceed 30 kg/hm^(2).The study could provide reference for tobacco production areas and cigarette industry enterprises to apply sulfur fertilizer reasonably and effectively control the sulfur content of tobacco leaves.
