Abstract

Abstract: 【Objective】 This study monitored emission regularity and loss of NH₃ and N₂O under different treatments in the summer maize fields on the long-term experiment platform, to explore effective ways to reduce gaseous nitrogen losses in summer maize field in the Huanghuaihai region, in order to provide a theoretical basis for improving the yield of summer maize and fertilizer use efficiency. 【Method】 The experiment was conducted with lysimeters in 2016-2017. The maize cultivar of Zhengdan 958 (ZD958) was used as experimented material. The venting method was used to monitor NH₃ volatilization, and the static box-gas chromatography method was used to monitor losses of N₂O under four fertilization modes, including organic manure (M₁), organic manure plus chemical N fertilizer (1/2 N from organic manure, 1/2 from urea; U₂M₂), Urea (U₁) and no N fertilizer (CK). The content of nitrogen in M₁, U₁ and U₂M₂ treatment were equal. 【Result】 Loss of gaseous nitrogen in maize field was dominated by NH₃ volatilization, accounting for 88.55%-96.42% of the total nitrogen gaseous loss and N₂O emissions was less. NH₃ volatilization was the highest under U₁ treatment, with an average of 38.19 kg·hm^-2of 2016 and 2017; the lowest treatment with M₁was 19.10 kg·hm^-2, indicating that single application of organic fertilizer or organic-inorganic combination application could significantly reduce NH₃ volatilization. N₂O emission was highest under M₁ treatment, which reached an average of 1.65 kg·hm^-2, and then 77.42% and 34.15% higher than those of U₁ and U₂M₂ treatment, respectively. Nitrogen use efficiency of U₂M₂ treatment was the highest, with an average of 58.20%; compared with M₁ and U₁ treatment, which increased 32.15% and 15.13%, respectively. The results showed that there was significant difference in yield among different fertilization treatments from 2016 to 2017, which showed U₂M₂> U₁> M₁> CK. Compared with the U₁ and M₁ treatment in 2016, the yield of U₂M₂ treatment was increased by 3.45% and 5.25%, respectively, and there was no significant difference in yield between U₁ and M₁ treatment. Compared with the U₁ and M₁ treatment in 2017, the yield of U₂M₂ treatment was increased by 5.83% and 12.53%, respectively, and the yield under U₁ treatment was significantly higher than that of M₁ treatment, increased of 6.33%. 【Conclusion】 Compared with single application of urea, organic-inorganic combination application could effectively reduce gaseous loss of nitrogen. Organic-inorganic combination application increased nitrogen use efficiency, dry matter and nitrogen accumulation, and maize grain yield, therefore, it was a reasonable way to increase yield and nitrogen utilization efficiency.
