摘 要：
在贵州乌蒙烟区109个地点开展野外调查、进行土壤及烟叶样品的采集和测定,从成土母岩类型、成土母质来源、土壤类型与养分、地形地貌4个方面分析了乌蒙清甜香烤烟风格形成的农业地质背景特征。结果表明:典型清甜香烤烟形成的成土母岩类型以碳酸盐岩类沉积岩和碎屑岩类沉积岩为主,清甜香烤烟以碳酸盐岩类沉积岩为主,弱清甜香烤烟以碳酸盐岩类沉积岩和粘土岩类沉积岩为主;影响清甜香烤烟亚型风格形成的成土母质来源和各来源所占比例各不相同,但均以坡积物为主;随着烤烟清甜香风格的增强,土壤类型以黄棕壤为主,土壤质地由粘向砂转变,典型清甜香烤烟风格形成的土壤有机质、速效氮、全钾、水溶性氯含量相对较低,而有效钾含量最高;典型清甜香烤烟形成的地貌类型以高中山地貌为主,清甜香烤烟在高中山地貌和中山地貌的分布比例接近,而弱清甜香烤烟以中山地貌为主。

摘 要：
We collected samples of soil and tobacco leaves from 109 field sites in Wumeng tobac- co-growing area in Guizhou Province,and identified the agro-geological background characteris- tics of light-sweet flavor style of flue-cured tobacco in terms of soil parent rock,parent material source,soil type and nutrition,and landform. The results indicate that carbonate and clastic sedimentary rocks are mainly the soil parent rocks for the typical light-sweet flavor style,carbon- ate sedimentary rocks for the light-sweet flavor style,and carbonate and clay sedimentary rocks for the weak light-sweet flavor style. Although the sources and compositions of parent materials that affect the formation of flue-cured tobacco styles are different,they are all characterized as slope sediments. Yellow brown soil and sand land can improve the light-sweet flavor of flue-cured tobacco,and the contents of organic matter,available nitrogen,total potassium,water-soluble chlorine in the soil for the typical light-sweet flavor style are low,while the available potassium content is the highest. Furthermore,the high-middle mountain landform is mainly responsible for the typical light-sweet flavor style,the shares of high-middle and middle mountain landform are equivalent for the light-sweet flavor style,and the middle mountain landform is for the weak light- sweet flavor style.
