Abstract:

In order to investigate the spatial distribution of soil available micronutrients and its influencing factors, and to provide a theory basis for management of micronutrients and fertilizing reasonably on tobacco, spatial distributions and patterns of 6 available microelements in soil in Luliang were analyzed based on geostatistics methods. The results indicated that: anisotropic structure of available microelements in tobacco soil varied evidently, and was auto-correlated to a moderate degree, spatial variability of 6 available microelements were caused by structural factors and random factors. Spatial distribution maps showed that, available B and available Zn were moderate in soil in Luliang County, available Cu, available Fe and available Mn were extremely high in the whole extension, available Mo was widely deficient in soil.
