Abstract：In order to explore the effects of different seeding rates on the growth stages of wheat,this experiment studied the influence of B1(seeding rate of 187.5 kg/ha),B2(seeding rate of 225.0 kg/ha)and B3(seeding rate of 262.5 kg/ha)on the agronomic traits and dry matter content of each growth stage of wheat through field experiments at the experimental demonstration base of the Zhumadian Academy of Agricultural Sciences.The results showed that with the increase of seeding rate,the dry matter content per plant,plant height from jointing stage to mature stage and leaf area per plant of wheat at each growth stage were the highest in B2,followed by B1 and the lowest in B3.B3 increased the height of overwintering wheat plants by 1.98 cm and reduced the leaf area per plant by 15.2 cm2 compared to B1.B3 also reduced the weight gain ratio of overwintering and jointing stage wheat by 0.95,0.55 g/cm.B3 significantly reduced wheat spike length and the number of fertile small spikes compared to B1 and B2.In general,an appropriate seeding rate could increase the leaf area per plant and dry matter content per plant,thereby improving the weight increase ratio and production of wheat.
