摘　　要：探讨不同播种期对鲜食糯玉米产量及相关性状的影响,为确定适宜播种期、制定栽培措施提供可靠依据。以春糯1和春糯10为试验材料,进行6个播期处理试验,播期设置分别为4月29日、5月9日、5月19日、5月29日、6月8日、6月18日。测定生育期、株高、穗位高、穗长、穗粗、秃尖长、单穗重、鲜整穗产量、鲜籽粒产量。结果表明,播期对鲜食糯玉米产量及相关性状均有显著的影响。随着播期的延迟,生育期缩短,播种至出苗期缩短,出苗至散粉的生理日期也缩短。株高、穗位高、穗长、单穗重、鲜整穗产量及鲜籽粒产量均呈先上升后下降的趋势,在5月29日处理达到最大值,5月19日处理次之,6月18日处理最小。穗粗各播期相差不大,前期比后期粗。秃尖长度随播期延迟逐渐增加。该试验在5月29日处理下获得最大产量,因此,长春及同积温地区糯玉米推荐适宜播期应在5月29日左右较为适宜。The effects of sowing date on yield and related characteristics of waxy corn were studied,to provide reliable basis for suitable sowing date and making cultivation measures of fresh-eating waxy corn.Taking Chunnuo 1 and Chunnuo 10 as research materials,we set up 6 sowing dates,which were April 29th,May 9th,May 19th,May 29th,June 8th and June 18th.We measured the growth period,plant height,ear height,ear length,ear thickness,bald tip length,weight per ear,fresh-ear yield and fresh grain yield.The results showed that the sowing date had a significant impact on yield and related characteristics of waxy corn in Jilin Province.As the sowing date was postponed,the growth periods were shortened,days from sowing to seedling,and from seedling to milling also were shortened.Plant height,ear height,ear length,weight per ear,fresh-ear yield and fresh grain yield increased firstly and then decreased with the sowing dates postponing,which reached the maximum at treatment May 29th,followed by treatment May 19th,and treatment June 18th took the last place.Ear thickness varied little and was thicker at the early stage than the late stage.Bald tip length increased with the delay of sowing date.The maximum yield was obtained under sowing date treatment May 29th,and the recommended suitable sowing date for Jilin waxy corn should be about May 29.
