摘　　要：为了探讨烟蒜轮作与套作对土壤农化性状及烤烟产量的影响,本试验在烤烟不同生育时期,采取单作烤烟、烟蒜轮作与套作种植方式下的土壤样品分析农化指标和统计烟叶产量,并对其结果进行对比分析。结果表明随生育期的推进,不同种植方式下根际土壤p H值呈增加趋势,烟蒜轮作与套作根际与非根际土壤的p H值均高于单作烤烟。上部叶成熟期,烟蒜轮作与套作根际与非根际土壤有机质含量均高于单作烤烟。下部叶与上部叶成熟期,烟蒜轮作与套作非根际土壤速效氮含量显著高于单作烤烟。而上部叶成熟期,烟蒜轮作与套作处理根际土壤速效磷、速效钾含量高于单作烤烟。烟蒜轮作与套作烟叶产量、上中等烟率较单作烤烟提高了35.04%和17.55%、5.88%和3.88%。烟蒜轮作与烟蒜套作种植方式均有利于缓解烟草连作障碍,改善土壤微生态环境,提高烤烟产量,但烟蒜轮作对其效果更加突出。本研究探讨烟蒜轮作与烟蒜套作种植方式对土壤农化性状及烤烟产量的影响,可为改良植烟土壤、减轻连作障碍及栽培制度的创新提供理论基础和技术支撑。To investigate the effects agrochemical characters and tobacco of tobacco garlic crop rotation and tobacco garlic crop intercropping on soil yield. In tobacco different mature stage, soil samples and tobacco yield were collected at tobacco monocuhure, tobacco garlic crop rotation and intercropping system. And analysis of the results. Results indicate that the soil pH in rhizosphere increased in different system, with the growing of tobacco. In addition the soil pH in non-rhizosphere and rhizosphere of tobacco garlic crop rotation and intercropping system were higher than that of tobacco monocuhure treatment. The organic content in tobacco rhizosphere and non-rhizosphere soils with the tobacco garlic crop rotation and intercropping treatment were higher than that of tobacco monocuhure at mature stage of upper leaf. Moreover, the available nitrogen content in tobacco non-rhizosphere soil with the tobacco garlic crop rotation and intercropping treatment were significantly higher than that of tobacco monocuhure treatment at mature stage of lower and upper leaf. The available phosphorus and potassium content in tobacco rhizosphere soil with the tobacco garlic crop rotation and intercropping treatment were also higher than that of tobacco monoculture treatment at mature stage of upper leaf. And furthermore, the tobacco yield and ratio of the middle class and superior leaves of tobacco garlic crop rotation and intercropping treatment increased by 35.04 and 17.55 percentage points, 5.88 and 3.88 percentage points compared to the tobacco monocuhure treatment, respectively. To sum up, the system of tobacco garlic crop rotation and intercropping can help mitigate the tobacco soil sickness, improve the soil microbial eco-environment and raise the yield of tobacco. Exploring the effects of tobacco garlic crop rotation and intercropping system on soil agrochemical characters and tobacco yield, which would provide a theoretical basis and technical support for improving tobacco soil, alleviating continuous cropping obstacle and
