不同播期对糯玉米石彩糯1号生长发育的影响

Effect of Different Sowing Date on Growth of Waxy Maize Shicainuo 1

[目的]研究石彩糯1号在河北石家庄地区的适宜播期。[方法]以糯玉米品种石彩糯1号为供试品种,研究不同播期对石彩糯1号鲜穗收获期、农艺性状、产量、品质和抗性的影响。[结果]石彩糯1号在河北石家庄地区适宜播种期为6月10日以前;在地温允许情况下,播种越早,鲜穗产量和1级穗率越高,种植收益越大。[结论]该研究为石彩糯1号在河北省大面积推广应用提供了科学依据。

[Objective]To study the appropriate sowing date of Shicainuo 1 in Shijiazhuang,Hebei.[Method]To study the effect of different sowing date on harvest time,agronomic traits,yield,quality and resistance by testing the waxy maize——Shicainuo 1.[Result]The appropriate sowing date for Shicainuo 1 in Shijiazhuang,Hebei Province is before June 1;with the permission of ground temperature,the earlier sowing date is,the higher yield and ear rate it returns and thereby the higher planting efficiency.[Conclusion] This study provides scientific reference for the application of Shicainuo 1 in a large area of Hebei Province.
