１９９１～１９９３年对我省肥料区划和土壤普查的耕地土样进行了收集筛选和分析调查。结果表明：我省耕地土壤多数含有效硫丰富，占总样本３３．９５％；耕地缺硫或潜在性缺硫，需要补充硫肥；缺硫土壤主要分布在我省黔东北、黔东南、黔南、黔西南等低海拔地区，影响土壤有效硫分布的主要因素有海拔高度、土壤有机质含量、土壤母质、母岩、土壤类型、地形地貌等。该调查为我省合理施用硫肥提供了依据。
From 1991 to 1993, the soil samples of cultivated land in our province’s fertilizer zoning and soil census were collected, screened and analyzed. The results showed that most of the cultivated soils in our province were rich in available sulfur, accounting for 33.95% of the total sample. Sulfur deficiency or potential lack of sulfur in cultivated land needed to be supplemented with sulfur fertilizer. The sulfur-deficient soil was mainly distributed in northeast Qiandongnan, Qiandongnan, South, Southwest Guizhou and other low altitude areas, the main factors affecting soil available sulfur distribution are altitude, soil organic matter content, soil parent material, parent rock, soil type, topography and so on. The survey provided a basis for the rational use of sulfur fertilizer in our province.
