| Abstract: | Objective] To select the best scheme of nitrogen fertilizer application after returning straw to fields.Method] Seven straw mulching plus nitrogen fertilizer treatments were conducted in the experiment,the effects of different treatments on soil nutrients,rice yield and structure were investigated.Result] The yield would be the highest and up to 9 600.90 kg/hm2 when pure nitrogen was applied at a concentration of 315 kg/hm2 after straw mulching.Conclusion] Application of 315 kg/hm2 nitrogen fertilizer after returning straw to fields can meet the needs of straw decomposition and rice growth. |
