- 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.
