Abstract
Effects of nitrogen application on dry matter accumulation,translocation and its relationship with yield for two wheat cultivars were investigated through field experiment in the typical high-yielding wheat area under five nitrogen rates(0,90,180,270,360 kg·hm-2)for two years.The results showed that wheat dry matter accumulation was increasing from wintering to maturity stage,yet the highest increasing ratio was at joint-anthsis stage,and next was in anthesis-mature stage for Yumai 49-198 and Lankao Aizao 8.With nitrogen fertilizer rate increasing,accumulation,translocation and grain yield of wheat dry matter increased.Yumai 49-198 got the highest accumulation at 270 kg·hm-2 nitrogen rate,while Lankao Aizao 8 got the highest accumulation at 180 kg·hm-2 nitrogen rate.Dry matter accumulation ratio in stem and sheath of Yumai 49-198 was lower than that of Lankao Aizao 8,yet in rachis and glumes was higher than that of Lankao Aizao 8 during anthesis stage.After harvest,Dry matter accumulation ratio in leaves,stem and sheath,rachis and glume for Yumai 49-198 was lower than that of Lankao Aizao 8,but in grain was higher than that of Lankao Aizao 8.Dry matter accumulation ratio and dry matter contribution to grain at pre-anthesis for Yumai 49-198 was lower than that of Lankao Aizao 8.
