Abstract
Objective] To study abundance evaluation of trace elements in tobacco planting soil of Nanbin in Shizhu County to provide refer-ences for the application of trace element fertilizers.[Method] 130 soil samples were collected from Nanbin in Shizhu County, and the content of trace elements in the soil samples were detected.[Result] The average content of water soluble chloride, available copper, available zinc, available iron, available manganese, available molybdenum, and available boron in the tobacco planting soil was 8.39, 1.44, 2.16, 56.39, 51.86, 0.10, and 0.18 mg/kg respectively.The average content of available zinc was at a middle level, and the average content of available copper was at a high level, while the average content of available manganese and iron was at a very high level , but the soil lacked water solu-ble chloride, available molybdenum and available boron.[Conclusion]According to the content of trace elements in tobacco planting soil of Nanbin in Shizhu County, boron and chlorine fertilizer should be applied in the tobacco planting soil of Nanbin in Shizhu County , and molyb-denum fertilizer should be applied in Linxi Town, Longsha Town, Liutang Township and Nanbin Town.关键词
