摘　　要：为指导重庆植烟区土壤硫素养分分区管理和硫肥合理施用,以2002、2012年重庆市植烟土壤普查数据和2021年重庆11个植烟区县2513个土壤有效硫数据为研究对象,全面分析2021年重庆植烟土壤有效硫时空分布特征及其影响因素。结果表明,2002、2012、2021年,重庆植烟土壤有效硫含量分别为34.24、51.40、45.30 mg/kg,先升高后下降。重庆植烟土壤硫适宜区比例仅占14.69%,缺硫区和硫过量区比例分别达29.61%和55.70%,各区县土壤有效硫缺乏和过量区并存。不同母质、土类和亚类间有效硫含量差异显著,潮土中有效硫含量最高。海拔、速效钾含量和土壤pH均为影响土壤中有效硫含量的关键因素,其中速效钾能够独立解释土壤有效硫变异的10.30%,提示应注意硫酸钾肥施用对土壤硫含量的影响。各烟区应结合本地实际情况,合理调整含硫肥料的施用量,以确保优质烟叶的生产。In order to quide soil sulfur quality management and rational application of sulfur fertilizer in Chongqing tobacco-growing area,based on the survey data of tobacco-growing soil in Chongqing in 2002 and 2012,and the data of 2,513 soil available sulfur in 11 tobacco-growing counties in Chongqing in 2021,the spatial and temporal distribution characteristics of available sulfur content in tobacco-growing soil in Chongqing in 2021,as well as its influencing factors were comprehensively analyzed.The results showed that in 2002,2012 and 2021,the available sulfur content of tobacco-growing soil in Chongqing was 34.24,51.40 and 45.30 mg/kg,respectively,which increased first and then decreased.The proportion of suitable sulfur areas in Chongqing tobacco-growing soil was only 14.69%,and the proportion of sulfur deficiency areas and sulfur excess areas were 29.61%and 55.70%,respectively.The contents of available sulfur in different parent materials,soil classes and subclasses are significantly different,and the content of available sulfur in tidal soil is the highest.Altitude,available potassium content and soil pH are the key factors affecting the content of available sulfur in soil,and available potassium can independently explain 10.30%of the variation of available sulfur in soil,suggesting that attention should be paid to the effect of potassium sulfate application on the content of sulfur in soil.In order to ensure the production of high-quality tobacco leaves,the application amount of sulfur-containing fertilizer should be reasonably adjusted in each tobacco area according to the local actual situation.
