| 摘 要： | 为了解黔西南州植烟土壤有机质含量分布特征及与其他土壤养分的关系,采用传统统计学、地统计学及灰色关联分析方法分析了黔西南州植烟土壤有机质含量状况、空间分布及与其他土壤养分的关系。结果表明:1黔西南州植烟土壤有机质含量较高,平均值为41.89 g/kg,变幅为14.35~79.65 g/kg,变异系数为35.21%,处于适宜范围内的样本占14.58%;2晴隆县、兴义市、兴仁县植烟土壤有机质极显著高于贞丰县、安龙县、普安县;3黔西南州植烟土壤有机质含量呈斑块状分布态势,总体上,从东北部和西南部向中部方向有机质减少的趋势;4碱解氮、全磷与土壤有机质的相关性达到显著或极显著正相关;5土壤养分与土壤有机质含量的关联顺序为:全氮碱解氮速效磷全磷硝态氮速效钾缓效钾铵态氮。

| Abstract: | In order to understand the distribution characteristics of organic matter contents in tobacco - grow- ing soil and its relation with other soil nutrients in Qianxinan, condition and spatial distribution of these nutri- ents were analyzed by the methods of traditional statistics, geo - statistics and grey correlation analysis. The results were as follows ： （ 1 ） organic matter contents of tobacco - growing soil was generally high, with a mean of 41.89 g/kg, amplitude of 14. 35 -79.65 g/kg and variation coefficient of 35.21% . Organic matter con- tents in 14.58% of the soil samples was suitable for tobacco cultivation. （2）The organic matter contents of tobacco - growing soil in Qinglong county, Xingyi city and Xingren county were extremely significant higher than those in Zhenfeng county, Anlong county and Puan county. （3） IDW interpolation map indicated that the spatial distributions of organic matter contents were patchiness, while decreased from the northeast and southwest to the middle. （4） The contents of available nitrogen and total phosphorus were increasing with the rise of organic matter in tobacco - growing soil, and they showed significantly positive correlations. （5） The grey correlation order was total nitrogen 〉 available nitrogen 〉 available phosphorus 〉 total phosphorus 〉 nitric nitrogen 〉 available potassium 〉 slowly available potassium 〉 ammonium nitrogen. |
