摘　　要：为确定内地主栽糜子品种引种到新疆西部干旱区的最佳种植时间,以期为北疆冷凉地区春播糜子高产优质提供理论依据和技术支撑。试验材料为内糜5号、固糜21号、陕糜1号、托里1号,设5个播期,依次为B1(5月15日)、B2(5月31日)、B3(6月15日)、B4(6月30日)、B5(7月15日),阐明不同播期下糜子品种的生育期、生长发育及产量的变化。结果表明:奇台当地播期B5(7月15日)糜子不能正常成熟,其余4个播期糜子均能安全成熟,且随着播期的推迟,各品种生育期逐渐缩短。株高、穗下节间长随播期延迟而降低。主穗长、单穗质量、千粒质量、产量呈单峰曲线变化,在B2处理达到峰值。从产量来看,内糜5号、固糜21号、陕糜1号、托里1号适宜早播,在5月中上旬播种,内糜5号产量最高可达3386.73 kg/hm^(2)。In order to determine the best planting time of the mainland owner’s planting Panicum miliaceum varieties to the dry area of the western in the west of Xinjiang,and provide theoretical basis and technical support for the high quality and high yield Panicum miliaceum in the cold area of the northern Xinjiang,the test materials were Neimi No.5,Gumi No.21,Shaanmi No.1 and Tori No.1,and No.5 sowing dates were set up including B1(May 15),B2(May 31),B3(June 15),B4(June 30),B5(July 15).The the growth period,growth development and yield changes of Panicum miliaceum varieties under different sowing dates were clarified.The results showed that Panicum miliaceum could not mature normally at the local sowing date B5(July 15)in Qitai,and the other four sowing dates could mature safely,and the growth period of each variety was gradually shortened with the delay of sowing date.Plant height and internode length decreased with the delay of sowing date.Panicle length,panicle weight,1000-grain weight and yield showed unimodal curve changes,and reached the peak value in B2 treatment.In terms of yield,Neimi No.5,Gumi No.21,Shannmi No.1 and Tori No.1 were suitable for early sowing.The highest yield of Neimi No.5 could reach 3386.73 kg/hm^(2) at sowing date of mid-early May.
