Surface Soil Available Phosphorus Content in Shaoyang Tobacco-growing Areas
摘要
Abstract
In order to find out the characteristic of available P contents in surface soils in Shangyang tobacco-growing are-as, the distribution of available P contents in 1 790 soil samples were analyzed. The results were as follows:(1) The a-vailable P contents in the surface soil in Shaoyang tobacco-growing area was on the high side,with a mean of 25.25 mg/kg and variation coefficient of 97.6%. About 27.99% of the soil samples had available P contents for suitable tobacco culti-vation. (2) The available P contents of surface soils in Shaoyang county and Xinning county were extremely significant more than that of Longhui county. (3) The contents of available P was decreased with the rise of pH in surface soils of Shaoyang tobacco growing areas. (4) The contents of available P increased with the rise of organic matter in surface soils of Shaoyang tobacco growing areas. (5) Kriging interpolation map indicated that the spatial distributions of available P re-duced from the middle to the northern and south-western.关键词
