In order to obtain high yield and high efficiency, four different cultivation and management modes [conventional management (T1), optimizing management (T2), super-high-yield management (T3), high yield and high efficiency mode(T4)] were conducted through field experiment at Yuzhou city of Henan province, and the effect of different fertilization and management modes on accumulation and translocation of dry matter and nitrogen after anthesis of winter wheat were investigated. The results showed that: compared with T1 treatment, the yield of T2, T3 and T4 treatments was increased by 15.9%, 31.5% and 25.4%, respectively; after anthesis, the amount of dry matter translocation was increased by 82.5%, 109.5% and 76.6%, respectively; and nitrogen transport capacity was increased by 50.9%, 49.1% and 41.2%, respectively. The results showed that the pre-anthesis nitrogen and dry matter accumulation could be improved through the optimization of fertilization management measure accompanied with increasing the post anthesis dry matter and nitrogen translocation amount and rate significantly, so as to improve the grain number and yield.Of the four modes,T3 had the highest yield,but T4 was most suitable for local promotion. |
