本研究采集黑龙江省29个市、县,发育于5种母质的8种土壤类型143个耕层土样,分析测试其全硫、有效硫含量;结果表明黑龙江省土壤全硫含量平均值为511.90mg/kg,有效硫含量平均值为26.27mg/kg。缺硫和潜在缺硫(有效硫含量<16mg/kg)土壤以风砂土和盐碱土居多,其次是黑土、黑钙土,而草甸土硫素含量丰富。缺硫面积最大的是黑土。按母质划分,发育于砂质沉积物的土壤100%缺硫,其次是发育于河湖冲积物和沉积物土壤,缺硫达65%以上。
In this study, soil samples from 143 soils of 8 soil types in 29 municipalities and counties in Heilongjiang Province were collected and analyzed for total sulfur and available sulfur. The results showed that the average content of total sulfur in Heilongjiang Province was 511.90 mg / kg, the average effective sulfur content of 26.27mg / kg. Lack of sulfur and potential sulfur deficiency (effective sulfur content <16mg / kg) The soil is mostly sandy soil and saline-alkali soil, followed by black soil, chernozem, while meadow soil sulfur content is rich. Sulfur deficiency area is the largest black soil. According to the parent material, 100% of the soil developed in sandy sediments is deficient in sulfur, followed by those developed in alluvial and sedimentary soils of rivers and lakes with a sulfur deficiency of more than 65%.
