Abstract:: Research on dry matter accumulation and transportation on the Changwu Tableland of China,the field experiments were conducted on the five different cultivation models,i.e.,Changwu134(T₁),Changhan58+top dressing 75kg/hm²(T₂),Changhan58+top dressing 75kg/hm²+organic fertilizer,organic fertilizer 4 500kg/hm²(T₃),Changhan58(T₄),and Changhan58+organic fertilizer,organic fertilizer 4 500kg/hm²(T₃).The results showed as following:dry matter accumulation amount gradually increased during grain-filling period.After anthesis period,dry matter accumulation and contribution rate to grain weight showed that T₄ was the highest,reached to 80.85%,T₁,T₂,T₅ reached to 77.97%,77.06%,77.65% respectively.And there were no significant difference among the three treatments.T₃ were promoted dry matter accumulation of grain filling stage and get the highest yield.
