摘　　要：在油菜／小麦轮作体系中，通过田间小区试验研究了不同含硫肥料对油菜生长、氮硫吸收及产量构成因素的影响。结果表明，在常规施肥的基础上增施含硫肥料可明显促进油菜生长，增加植株对氮和硫的吸收。增施含硫肥料的处理与常规施肥处理相比油菜植株单株结荚数、角果长和每角果粒数等均有不同程度的提高。增施含硫肥料的处理比常规施肥处理的油菜籽产量增加658．3～1335．3kg·hm^-2，增幅25．5％～51．6％。施硫处理产投比为3．3—16．1。A field experiment was conducted rapeseed plant, N and S uptake by plant, the yield tem of rapeseed and wheat. The results showed that S fertilizer applications, such as sulphur, potassium to study the effect of sulphuric fertilizers on the growth of the component factors and seed yield of rapeseed in the rotation syscompared with the control that only supplied N and P fertilizers, sulphate and calcium sulphate, improved the growth of the plant, increased the uptake of S and N by the plant, and increased pod number, pod length and the seeds of per pod. The yield of the rape seed were increased 658.3 - 1 335.3 kg per hectare by applying S fertilizers,the increased yield were 25.5% -51.6% higher than the control. The input vs. out ratio reached 3.3 - 16.1.
