| 摘 要： | 在３个地区７个点进行油菜硫肥试验。结果表明，施用硫肥比不施硫肥的油菜生长好，菜籽产量高。土壤ＳＯ—Ｓ含量在２６．０ｍｇｋｇ－１以下，施用硫铵的比对照增产１４．８％—４９．８％，达到极显著或显著水平，施用硫磺比对照增产６．５％—３４．２％，达极显著或显著水平。土壤ＳＯ—Ｓ含量＞４５．０ｍｇｋｇ－１，施硫铵、硫磺和石膏均比不施硫肥的增产，但未达显著水平。

| Abstract: | Seven field experiments were conducted in three regions to investigate effects of applying sulphur fertilizer to soil on rapeseed yield.Sulphate content in soil samples was analysed before tests using isotop dilution method.Application of ammonium sulphate,element sulphur or gypsum resulted in improvement of rapeseed growth and increase of seed yield compared with control.The effects in soils with lower negative sulphate content were singnificant at 0.01 or 0.05 levels. |
