Abstract: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.
