| 摘 要： | 采用GPS定位技术,对贵州省铜仁市202个植烟土壤样点进行了取样测定,采用地统计学技术和地理信息技术相结合的方法,对该地区植烟土壤主要养分空间变异特征进行研究。结果表明,铜仁市植烟土壤有机质含量为5.47~59.81g/kg,碱解氮27.33~241.32mg/kg,有效磷1.50~115.96mg/kg,交换性钾46.20~977.10mg/kg。铜仁市植烟土壤中有机质和交换性钾含量丰富,碱解氮含量偏高,应适当控制相应肥料的施用;33.70%的植烟土壤有效磷含量高于30mg/kg,建议这些区域适当控制磷肥的施用量;30.70%的植烟土壤有效磷含量低于15mg/kg,建议这些区域注重增施磷肥,以满足烟草正常新陈代谢和品质形成的需要。铜仁市植烟土壤有机质与碱解氮含量的空间分布具有一定的相关性,均呈现由东往西增加的趋势,在垂直分布上有机质、碱解氮和交换性钾含量与海拔呈极显著正相关。

| Abstract: | Using GPS positioning technology, 202 tobacco planting soil samples were sampled and analyzed in Tongren, Guizhou province. The spatial variation characteristics of main nutrients in tobacco planting soil were studied by combining geostatistics and geographic information technology. The results showed that the contents of organic matter, alkaline hydrolyzable nitrogen, available phosphorus, and exchangeable potassium in tobacco planting soil were 5.47-59.81g/kg, 27.33-241.32mg/kg, 1.50-115.96mg/kg and 46.20-977.10mg/kg, respectively. The contents of organic matter and exchangeable potassium were rich, and the content of alkali hydrolyzed nitrogen was relatively high, so the application of corresponding fertilizer should be properly controlled. The content of available phosphorus in 33.70% of tobacco planting soil was higher than 30mg/kg. It was suggested that the application rate of phosphorus fertilizer should be properly controlled in these areas. The content of available phosphorus in 30.70% of tobacco planting soil was less than 15mg/kg. It was suggested that more phosphorus fertilizer should be applied in these areas to meet the needs of tobacco normal metabolism and quality formation. The spatial distribution of organic matter and alkali hydrolyzed nitrogen content in tobacco-growing soil in Tongren showed a certain correlation and both showed an increasing trend from east to west. In the vertical distribution, the contents of organic matter, alkali hydrolyzed nitrogen, and exchangeable potassium showed an extremely significant positive correlation with altitude. |
