摘要:

为探明赣州烟区植烟土壤硒禀赋、理化性质特征及其对烟叶产质量与硒积累的影响,支撑富硒烟叶科学开发与土壤精准改良,以赣州8个主产烟县为对象,连续采集植烟土壤与烟叶样品,测定土壤pH、硒、有机质、全氮、有效磷、速效钾及烟叶硒含量,结合2022—2024年连续3年烟农烟叶产量与上等烟比例数据,对土壤因子与烟叶产质量开展方差分析、相关性分析。结果表明:(1)植烟土壤硒含量均值0.23 mg/kg,低于赣州市均值,约75%样品属足硒水平;土壤酸碱度均值pH 5.5,呈弱酸性;有效磷含量处于极丰富水平,均值85.57 mg/kg;速效钾含量县域差异显著。(2)土壤有机质与全氮、硒呈极显著正相关(r=0.54**r=0.48**P<0.01);烟叶硒含量低(中部叶C3F为0.05 mg/kg,上部叶B2F为0.06 mg/kg),且与土壤硒无显著相关性。(3)速效钾含量可能是提升烟叶产量与等级的关键因子(2024年单产r=0.28**,上等烟比例r=0.32**P<0.01)。研究表明,赣州烟区植烟土壤硒生物有效性不足可能是制约富硒烟叶开发的核心因素,土壤呈现“磷过量、钾分化、氮适中、酸适中”特征。建议采取外源补硒为主、分区精准施钾、控磷增有机质的综合调控策略。研究结果为赣州特色富硒烤烟提质增效提供理论依据与技术支撑,后续可开展硒形态与根际调控机制研究。

Abstract:

This study investigated the characteristics of selenium (Se) and physicochemical properties in tobacco-growing soils of Ganzhou and their effects on tobacco yield and quality, aiming to provide a scientific basis for developing Se-enriched tobacco and soil amelioration. Tobacco-growing soil and tobacco leaf samples were collected from eight tobacco-producing counties in Ganzhou. Soil pH, Se, organic matter (SOM), total nitrogen (TN), available phosphorus (AP), available potassium (AK), and tobacco leaf Se content were determined. Yield and premium-grade tobacco proportion data of farmers from 2022 to 2024 were integrated. Variance and correlation analyses were employed to identify key soil factors affecting tobacco yield and quality. The results showed that: (1) the mean soil Se content was 0.23 mg/kg, lower than the average level of Ganzhou City, with about 75% of samples at a sufficient Se level. Soil pH averaged 5.5, being slightly acidic. AP content was extremely abundant, with a mean value of 85.57 mg/kg. AK content varied significantly among counties. (2) SOM showed highly significant positive correlations with TN and Se (r=0.54**, r=0.48**, P<0.01). Tobacco leaf Se content was low (middle leaves C3F: 0.05 mg/kg; upper leaves B2F: 0.06 mg/kg), and no significant correlation was found between soil and leaf Se content. (3) AK was probably a key positive factor for yield and grade (2024 yield: r=0.28**; premium-grade tobacco proportion: r=0.32**; P<0.01). In conclusion, low Se bioavailability in tobacco-growing soils may be the core constraint for developing Se-enriched tobacco in Ganzhou, necessitating exogenous Se supplementation. The soil presents the characteristics of ‘excessive phosphorus, potassium differentiation, moderate nitrogen, and moderate acid’. It is suggested to adopt the comprehensive regulation strategy of exogenous selenium supplementation, precise potassium application in different regions, phosphorus control and organic matter increase, so as to provide theoretical basis and technical support for improving the quality and efficiency of selenium-enriched flue-cured tobacco in Ganzhou.
