江淮丘陵地区下蜀系黄土母质发育的水稻土油稻轮作试验表明，油菜种植期间，耕层土壤硫主要来源于耕层以下土层的补给，其次是大气干湿沉降；该时期耕层土壤硫输出主要是油菜吸收，其次是淋失．油菜种植期间耕层土壤硫输入量小于输出，导致耕层土壤硫库下降８．７６ｋｇ·ｈｍ－２，２２％来自无机硫库的下降．水稻种植期间，耕层土壤硫输入主要来自灌溉水，其次是底土层的补给和大气干湿沉降；而硫输出主要是淋失，其次是水稻吸收．耕层土壤硫输入量大于输出，导致耕层土壤硫库增加１８．６９ｋｇ·ｈｍ－２，１８％来自无机硫库的增加．全年油稻轮作期间耕层土壤硫输入量大于输出，导致耕层土壤硫库增加９．９３ｋｇ·ｈｍ－２，１３％来自无机硫库的增加．
During the rapeseed cultivation, the soil sulfur of the topsoil mainly came from the supply of soil under the top of the plow layer, followed by the wet and dry subsidence of the atmosphere during the cultivation of paddy soil. Sulfur output is mainly absorbed by rapeseed, followed by leaching. During the rapeseed cultivation, the soil sulfur input was less than that of the output, resulting in a decrease of 8.76 kg · hm-2, 22% of the sulfur pool in the topsoil from the decrease of inorganic sulfur pool. During the rice planting period, sulfur input in topsoil mainly came from irrigation water, followed by subsoil recharge and atmospheric wet and dry deposition. Sulfur output was mainly leaching, followed by rice absorption. Sulfur input into the topsoil was larger than that from the output, resulting in an increase of 18.69 kg · hm-2 and a rise of 18% from the inorganic sulfur pool in the topsoil. During the whole year of oil-rice rotation, the soil sulfur input was greater than that of the output, resulting in an increase of 9.93 kg · hm-2 and 13% of the soil sulfur pool from the inorganic sulfur pool.
