采集了江西16个县市9种主要母质的609个农田耕层土样进行了土壤有效硫含量测定。统计结果表明:平均值为26.71mg/kg,缺硫和潜在缺硫样点占39.10%。按地区分,以赣南、赣东北山区缺硫最严重,有效硫小于12mg/kg的样点占26.60%~44.70%,其次是丘陵地区,有效硫小于12mg/kg的样点占10.00%~19.00%。按母质分,母质中以石英岩、花岗岩发育的土壤最缺,约占50%~60%,其次是红砂岩、泥质岩,缺硫为30%~40%,这些是江西省急需施用硫肥的土壤。水稻土以黄砂泥田、麻砂泥田、红砂泥田、鳝泥田等土属缺硫面积最多,全省缺硫水稻土面积约为103.8万hm2,约占水稻土面积的34%。
A total of 609 topsoil samples from 9 main parent materials in 16 counties of Jiangxi Province were collected for soil available sulfur determination. The statistical results show that: the average value is 26.71mg / kg, sulfur deficiency and latent sulfur sample occupy 39.10%. By region, the samples with the most severe sulfur deficiency and the effective sulfur less than 12mg / kg accounted for 26.60% ~ 44.70% in the mountainous areas of southern Jiangxi and northeastern Jiangxi, followed by the hilly areas and the samples with available sulfur less than 12mg / kg Accounting for 10.00% ~ 19.00%. According to parent material, most of the soil with quartzite and granite in parent material is the most developed, accounting for 50% -60%, followed by red sandstone and mudstone with sulfur deficiency of 30% -40% Fertile soil. Paddy soil is the area with the largest amount of sulfur deficiency such as yellow sand mud field, mud sand mud field, red sand mud field and eel paddy field. The sulfur deficiency paddy soil area in the province is about 1.038 million hm2, accounting for 34% of the paddy soil area.
