摘　　要：[目的]探讨不同播期与播量对小麦新品种涡麦99产量的影响,制定配套的高产栽培技术标准。[方法]在沿淮淮北地区的安徽省龙亢农场采用裂区试验研究了不同播期与播量对涡麦99产量及构成因素的影响。[结果]不同播期与播量对涡麦99产量构成因素及农艺性状影响显著,推迟播期降低了涡麦99的成穗数、穗粒数、千粒重和产量,降低了株高和穗长;增加播量能提高成穗数、产量、株高和不孕小穗数,降低穗粒数、千粒重、穗长和小穗数。[结论]建议涡麦99在沿淮淮北地区10月下旬播种,以225 kg/hm2的播量有助于提高其产量。[Objective] Investigating the effects of different sowing date and rate on the yield of new wheat variety Guomai 99, and developping a set of high yield cultivation technology standard. [Method] The effect of different sowing date and rate on the yield and yield components of wheat variety Guomai 99 were studied by split plot experiment. [Result] Different sowing date and rate had significant effect on yield components and agronomic characters of wheat Guomai 99. The number of spike, grain number, 1 000-grain weight, yield, plant height and ear length were decreased by delaying sowing date. The spike number, grain yield, plant height and sterile spikelet number were increased by increasing sowing rate, but the grain number per spike, 1 000-grain weight, spike length and spikelet number were decreased. [Conclusion] It was proposed that Guomai 99 was suitable for sowing in late October in the region of north of Huaihe River, and it was helpful to increase the yield with 225 kg/hm2 of sowing rate.
