| Abstract: | In this experiment,we conducted five different treatments of nitrogen ratio of base and topdressing to winter wheat,the topdressing proportion to the total amount of nitrogen was between 0 and 100%,the amplitude was 20%.The results indicated that winter wheat in the zhuanglang county as the representative of dry and cold areas of loessal soil,nitrogen optimal base fertilizer proportion to the total amount of nitrogen was 69.63%,namely 2/3. |
