Effects of Sowing Date and Planting Density on Agronomic and Quality Characters of Zhenmai 168

In order to pursue suitable sowing date and planting density of high yield and quality cultivation for Zhenmai168,the effects of sowing date and planting density on yield and quality of Zhenmai168were investigated in this study.The experiment treatment applied the two factor randomized block design.The results showed that sowing time and planting density significantly affected the yield of Zhenmai168,which also had a strong influence on some agronomic and quality traits.With the delay of sowing,yield,dough formation time,dough stability time,content of wet gluten increased firstly and then decreased.Appropriate control of wheat planting density was able to increase the number of effective spikes,grain number per spike and thousand-grain weight,and finally increased yield,and which may also improve the dough stability time,grain protein content and wet gluten content.Under this experiment condition,both good quality and high yield were obtained with the suitable sowing date at October 31,and suitable planting density of 270×104 plants·hm-2 for Zhenmai168.
