Spatial and Temporal Variability of Soil pH in Longyan Tobacco Planting Areas
摘要
Abstract
The spatial and temporal variation of pH value of tobacco-growing soil in Longyan tobacco-growing areas was studied by the combination of traditional statistics and geostatistics. pH values of tobacco planting soil in Longyan tobacco-growing areas in 1982, 2001 and 2011 was 5.34, 5.03 and 5.23, respectively, meaning soil acidification was effectively inhibited. The semi-variance function model of soil pH in 1982, 2001 and 2011 was a linear model, linear model and exponential model correspondingly. In terms of spatial distribution, the high-value areas in 1982, 2001 and 2011 was in the form of block, dot and block accordingly. The areas that are not suitable for growing flue-cured tobacco show a trend of increasing first and then decreasing, and the area of the most suitable area is reduced.关键词
