| 摘 要： | 为探讨微肥的精准施用,采用地统计和GIS技术相结合的方法,研究了植烟土壤有效态微量元素(有效铁、锰、铜、锌)的空间变异规律。结果表明,土壤有效态微量元素变异幅度在22.0%～48.4%之间,表现出中等强度的空间变异性。4种微量元素的空间结构模型均符合球状模型,利用克里格法生成4种元素的空间分布图显示,研究区域有效铜和有效锰整体为中等偏高水平,有效铁和有效锌含量缺乏的区域分别占78%和43%。 |

| Abstract: | Spatial distribution of soil available micro-elements in tobacco planting fields was studied to provide theoretical basis for precision application of micro-fertilizers using geostatistics and GIS technique on small scale.Results showed that soil available microelements(Fe,Mn,Cu,and Zn) had medium variability with coefficient of variation from 22.0% to 48.4%.The semivariograms of available microelements could be fitted well with the spherical models.Kriging method was used to generate spatial distribution m... |
