摘　　要：在大田条件下,设置了3个施硫水平和3个灌水水平,选用兰考矮早8号和豫麦49-198号为试验材料,研究了不同施硫量和灌水次数对冬小麦籽粒中淀粉含量及产量的影响.结果表明,不同施硫处理中,以60kg/hm2处理产量最高,并达显著差异水平,增产幅度可达19.7%.各灌水处理间,两小麦品种产量均以W2处理产量最高;分析水硫互作效应,2小麦品种产量均表现W1S60组合产量最高;两小麦品种籽粒总淀粉含量在不同供硫处理和灌水处理下均表现为S60和W0最高.以上结果表明,硫肥在一定程度上可以减缓干旱逆境胁迫,降低生产成本.With wheat cultivars Lankao aizao 8 and Yumai 49-198 as test materials,a field experiment was conducted to study the effects of three sulphur application rates （60,30,0 kg/hm^2） ,three irrigation treatments （irrigation at jointing and filling stages, at jointing stage and no irrigation）, and their combinations on starches content in grain and yield. The results showed that grain yield of the treatment with 60 kg/hm^2 （S60） was higher than that of the others and their differences reached the significant level Comparing to control （S0）, the grain yield increased 19.7 %. Among the irrigation treatments, the highest yield of two cuhivars was the W2 treatment. Applying 60 kg/hm^2 of S combined with irrigation at jointing stage （W1S60）was the ideal management regime for the high yield. Among the sulphur application and irrigation treatments, the highest starches content in grains of two cuhivars was the W0 and S60. The result show that applying sulphur fertilizers would slowdown drought stress, this reduced production cost.
