摘　　要：以两个不同品质类型冬小麦品种济麦20（强筋型）和鲁麦21（弱筋型）为材料,在0~20 cm土层有效硫含量为7.28 mg/kg的条件下,研究硫肥对冬小麦穗花发育、籽粒蛋白质组分和几个品质指标的影响。结果表明：在常规栽培措施下,增施硫肥提高了小麦的小花数,降低了不育小花数;提高了籽粒的结实率和籽粒中醇溶蛋白、谷蛋白、清蛋白含量;且施硫后,两品种籽粒的湿面筋含量、沉淀值、面团形成时间和稳定时间均有不同程度的提高,但对千粒重无显著作用,对济麦20的容重有显著的降低作用。Taking strong-gluten wheat Jimai 20 and weak-gluten wheat Lumai 21 as test materials,the effects of sulfur fertilizer on the floret development,protein components and several quality indicators were studied under 7.28 mg/kg of available sulfur in 0~20 cm soil layer.The results showed that under the conventional cultivation and management conditions,sulfur fertilization increased the floret number,reduced the male-sterile floret number,increased the seed setting rate and the contents of prolamin,glutenin and albumin.The grain wet gluten,sedimentation,dough development time and stability time also increased in different extent after sulfur fertilization.It also had no significant effect on 1 000-grain weight,but significantly decreased the bulk density of Jimai 20.
