为了研究龙山县植烟土壤有效硼分布状况及影响因素,以期为龙山县植烟土壤硼素的养分管理及特色优质烟叶开发提供理论依据;在龙山县采集植烟土壤样本294个,采用地统计学、多元统计学方法研究植烟土壤有效硼的空间分布及其影响因素,从描述性统计结果来看,龙山县植烟土壤有效硼含量总体丰富,平均值为0.792mg/kg,但变异较大,适宜样本比例为33.33%;从地统计分析结果来看,龙山县北部及东南部有效硼含量丰富,西部较为缺乏;影响因素研究的结果显示,随着海拔高度上升土壤有效硼呈先上升后下降的趋势;土壤有效硼与交换性钙及交换性镁呈极显著正相关关系;土壤有效硼含量随土壤有机质含量升高而升高;土壤有效...

In order to study the distribution and influencing factors of available boron in tobacco-growing soils,and to provide theoretical basis for the nutrient management of tobacco-growing soils and the development of characteristic and high-quality tobacco leaves,294 tobacco-growing soils were collected in Longshan County,and the spatial distribution of available boron in tobacco-growing soils and its influencing factors were studied by geostatistics and multivariate statistics.According to the descriptive statistical results,the available boron content of tobacco-growing soils in Longshan County w...
