摘要
为了探明六盘水烟区的土壤钾硫含量,实现烟叶增钾降硫优质生产,于2021年对盘州、水城和钟山等植烟区0~20 cm耕层土壤进行了土壤pH值、土壤速效钾含量、土壤有效镁含量及土壤有效硫含量的分析,并于2021年5月在盘州设置了硅基钾肥不同比例替代硫酸钾的田间试验。结果表明:六盘水烟区土壤pH值、土壤速效钾含量、土壤有效镁含量及土壤有效硫含量分别为5.9、302.2 mg/kg、186.1 mg/kg和44.7 mg/kg;与常规施肥相比,硅基钾肥替代1/4硫酸钾的处理可提高烟叶产量19.9%,明显提高烟叶钾、镁含量,降低硫含量,烟叶内部成分更协调。
In order to explore the soil potassium content and sulfur content in Liupanshui tobacco area and achieve high-quality production of tobacco with increasing potassium and reducing sulfur,this paper analyzed the soil pH value,available potassium content,available magnesium content and available sulfur content of 0-20 cm topsoil in tobacco planting areas such as Panzhou,Shuicheng and Zhongshan in 2021.Field experiments with replacing potassium sulfate with different proportions of silicon-based potassium fertilizer were conducted in Panzhou in May 2021.The results showed that the soil pH value,soil available potassium content,soil available magnesium content and soil available sulfur content in Liupanshui tobacco area were 5.9,302.2 mg/kg,186.1 mg/kg and 44.7 mg/kg,respectively.Compared with conventional fertilization,the treatment of replacing 1/4 potassium sulfate with silicon-based potassium fertilizer could increase tobacco yield by 19.9%,significantly increase potassium and magnesium contents,reduce sulfur content and make the internal components of tobacco more coordinated.
