摘要： 为了解邵阳烟区植烟土壤有效硼含量分布状况，测试邵阳烟区1790个土壤样本的有效硼含量，采用传统统计学和地统计学方法分析邵阳烟区植烟土壤有效硼含量适宜样本分布和在县域、乡镇、pH组、有机质组的差异及空间分布。结果表明：（1）邵阳烟区植烟土壤有效硼含量总体上丰富，平均值为0.80 mg/kg，变异系数为42.92%，处于适宜范围内的样本占27.26%。（2）隆回县和新宁县植烟土壤有效硼含量极显著高于邵阳县。（3）邵阳县九公桥镇、邵阳县黄塘乡植烟土壤有效硼含量均值在适宜范围。（4）不同pH组的植烟土壤有效硼含量差异达极显著水平。（5）不同有机质含量组的植烟土壤有效硼含量差异不显著。（6）植烟土壤有效硼含量呈斑块状分布，以有效硼含量0.6~0.9 mg/kg为主要分布面积。

Abstract: In order to understand the distribution of available boron contents for tobacco-growing soils in Shangyang, distribution frequency and difference in different county, towns, Ph group, organic matter group and Spatial distribution of available boron contents were analyzed by collected 1790 soil samples. The results were as follows:(1) The available boron contents in the tobacco-grown soil is an abundant supply for tobacco cultivation，with a mean of 0.80mg/kg and variation coefficient of 42.92%. About 27.26% of the soil samples had available boron contents for suitable tobacco cultivation. (2)The available boron contents of tobacco-growing soils in Longhui county and Xinning county were extremely significant more than Shaoyang county.(3) The tobacco-growing soils in Jiugongqiao town and Huangtang towmship had available boron contents for suitable tobacco cultivation.(4) There is extremely significant differences among the contents of available boron in the different pH group.(5)There is no-significant differences among the contents of available boron in the different organic matter group.(6)Kriging interpolation map indicated that the spatial distributions of available boron were patchiness, while the 0.60～0.90mg/kg were main distribution of available boron contents.
