以红壤为研究对象，施用硫磺和硫酸钾肥料（S0-S和SO42--S）进行盆栽油菜试验，探讨硫的转化与生物有效性以及对油菜生长、养分吸收和分配的影响。研究结果表明：两种肥料处理的油菜生物量没有显著差异，可能与N、S代谢有关，N/S比较小不适宜造成的。从油菜吸S量来说，硫磺的效果较好。从产量构成因素的荚果数、千粒质量、产量和收获系数变化看，随着硫肥用量的增加，硫磺处理的值降低，而硫酸钾处理的值增加，表明硫磺用量可能过量而硫酸钾中有钾的作用。 S促进油菜对P、Ca、Mg的吸收，而K2 SO4肥料由于K的拮抗作用，对Ca、Mg吸收量减少。在土壤中，SO42--S处理土壤交换性Ca、Mg含量高于S0-S处理，表明K可以提高土壤Ca、Mg有效性。

A pot experiment with red soil was carried out in a greenhouse for studying the effects of differ-ent rates of elemental sulphur(S0-S)and potassium sulfate (SO42--S)fertilizers on the growth,nutrient uptake and distribution of oilseed rape and nutrient change in rhizosphere and non -rhizosphere soil .The result showed that there were not significantly differences between two kinds of sulphur fertilizer treatments on canola bio -mass,which maight be associated with N ,S metabolism,and inappropriate small N/S ratio.The S content ab-sorbed by rapeseed in the S 0-S fertilizer treatment was higher than that in the SO 4 2--S treatment .The values of the pod number ,kilo-grain weight ,yield and harvest index decreased with the increasing rate of S 0-S fertiliz-er,while the values increased in the SO 42--S treatment,which indicated an excess amount of S 0-S fertilizer, and the role of potassium in SO 4 2--S fertilizer.S could promote the uptake of P ,Ca,Mg The uptake contents of Ca,Mg decreased in the K 2 SO4 fertilizer treatment owing to the antagonism of K .In the soil,the contents of soil exchangeable Ca ,Mg.were higher in the SO 4 2--S fertilizer treatments than those in the S 0-S fertilizer treat-ment,which showed that K could increase the validity of soil Ca ,Mg.
