摘　　要：豫丰11是河南省科学院同位素研究所选育的高产、优质中强筋小麦新品种。为明确不同种植模式对小麦生长发育及产量形成的影响,于2018~2019年小麦生长季节,采用二因素裂区试验设计,研究以播期和播量为主的不同种植模式对豫丰11生长发育及产量的影响。结果表明,播期和播量对豫丰11产量及构成要素的影响均达到极显著水平。随着播期的推迟,成穗数、穗粒数和产量表现等均出现先增后减的趋势,而千粒重则表现出递减趋势;随着播量的逐渐增大,成穗数表现为递增趋势,而穗粒数和千粒重表现为递减趋势,产量则表现为先增后减趋势。豫丰11在豫中部地区适宜播期为10月15~22日,播种密度为135~195 kg/hm2时可以获得较好的产量,同时根据生产实际情况,以具体播期定播量。通过不断协调提高豫丰11的产量构成要素,充分发挥该品种的高产潜力和最大经济效益,以促进农民增产增收。Yufeng 11 is a new wheat variety with high yield and good quality,which was bred by Isotope Institute Co.,Ltd.of Henan Academy of Sciences.In order to clarify the regulation mechanism of planting pattern on wheat growth and yield.In this paper,two-factor fracture zone test design was adopted mainly in sowing date,the planting densities was divided in 2018-2019.The effects of different sowing date and planting densities on growth and yield of new wheat variety Yufeng 11 were studied.The results of this experiment showed that sowing date and planting density significantly affected yield and its components of Yufeng 11.With the delay of sowing date,the spike number,the kernel number per spike and yield showed the trend of increasing first and then decreasing,while the 1000-grain weight showed the trend of decreasing.With the increase of planting density,the spike number showed the trend of increasing,while the kernel number per spike and 1000-grain weight showed the trend of decreasing,and the yield showed the trend of increasing first and then decreasing.The suitable sowing date of Yufeng 11 in central Henan is October 15-22,with the density of 135-195 kg/ha could reach a higher yield.At the same time,according to the actual production situation,the planting density is determined according to the specific sowing date.In conclusion,by continuously coordinating and improving the yield components of Yufeng 11,we can give full play to its high-yield potential and maximum economic benefits,so as to promote farmers to increase production and income.
