摘　　要：硫是植物生长必需的营养元素,缺硫会导致作物的产量和品质下降。生物炭是一种高温热解富含有机官能团的活性炭,施加生物炭对黄土中硫素的迁移转化产生重要的影响,可以有效减缓硫素的淋溶损失。综合评述了黄土中生物炭对硫素的影响与环境效应,对于区域施肥和硫肥的调控具有重要的意义。Sulfur is an essential nutrient element for plant growth.Crop sulfur deficiency will lead to the decline of crop yield and quality.Biochar is a kind of activated carbon rich in organic functional groups produced by high temperature pyrolysis.The application of biochar has an important impact on the migration and transformation of sulfur in loess,which can effectively slow down the leaching loss of sulfur.This paper reviews the impact of biochar in loess on sulfur and its environmental effects,which is of great significance for regional fertilization and regulation of sulfur fertilizer.
