摘　　要：为探讨药剂拌种对沿淮地区迟播小麦的壮苗效应及产量的影响,以淮麦33为试验材料,设置3个不同药剂拌种处理和1个不拌种对照处理,调查分析了对小麦田间生长及产量影响.结果表明:与不拌种相比,药剂A1及A2可以降低小麦第1叶出叶高度及第1、2节间长度,从而使株高降低;同时可以促进生物量积累,增强小麦分蘖能力,增加有效穗数.其中A1药剂组的千粒重性状表现较好,产量增加显著;A3药剂组增加了小麦节间长度及株高,营养生长旺盛,分蘖能力较强,有效穗数增加,产量得到提高,但每穗粒数有所降低.综上表明,药剂拌种具有壮苗效应、促进分蘖,促进小麦稳产增产,其中药剂A1表现最优.To investigate the effects of seed dressing agents on the seedling vigor and yield of late-sown wheat in Huai River region,"Huaimai 33"was used as the experimental material.Three different seed dressing treatments and one untreated control treatment were established to assess their impacts on field growth and yield of wheat.The results showed that compared to the untreated control,seed dressing agents Al and A2 reduced the emergence height of the first leaf and the length of the first and second internodes,thereby reducing plant height.They also promoted biomass accumulation,enhanced tillering ability,and increased the number of effective spikes.The A1 treatment group exhibited better thousand-grain weight characteristics and significantly increased yield.The A3 treatment group increased the length of internodes and plant height,resulting in vigorous vegetative growth,strong tillering ability,and an increased number of effective spikes,although the number of grains per spike was somewhat reduced.In summary,seed dressing agents promoted seedling vigor,enhanced tilering,and stabilized or increased wheat yield,with agent A1 showing the best performance.
