| 为探究不同类型缓控释氮肥配方一次性侧深施用对水稻产量、氨挥发和温室气体排放的影响，本试验在两种土壤质地（砂土和黏土）中选用南粳5718为材料，并设置常规施肥对照（CK）和4种缓控释氮肥配方：硫包膜缓释掺混肥（T1）、树脂包膜控释尿素Ⅰ+普通尿素（T2）、树脂包膜控释尿素Ⅱ（T3）、树脂包膜控释尿素Ⅰ+普通尿素+硝化抑制剂（T4）。结果表明：与 CK处理相比，T1处理在砂土和黏土中的水稻产量有所降低，而T2~T4处理增加了水稻产量，分别增产了3.35%~18.33%和2.40%~9.64%，其中T3处理在砂土和黏土中的增产效果显著，产量分别提高了18.33%和9.64%；与T1处理相比，T2~T4处理在砂土和黏土中减少了氨挥发，分别减少了62.13%~69.97%和12.16%~47.76%，其中，添加硝化抑制剂处理（T4）增加氨挥发损失量，在砂土和黏土中较未添加处理（T2）分别提高了 26.11% 和 68.16%；与 T1 处理相比，T2~T4 处理在砂土和黏土中分别减少了 17.09%~45.60% 和 0.99%~31.24%的CH4排放，其中，添加硝化抑制剂处理（T4）能够减少稻田CH4和N2O排放，在砂土和黏土中较未添加处理（T2）分别减少了12.11%和0.99%的CH4排放，以及51.87%和42.50%的N2O排放。综上，在砂土和黏土中，T2~T4处理较CK处理能够实现水稻的平产或增产，并且与T1处理相比，在减少稻田氨挥发和温室气体排放方面表现出显著优势。T3处理在黏土中施用能够增加水稻产量，有效减少稻田氨挥发及CH4和N2O排放。 |

| To explore the effects of one-time side deep application of different types of slow/controlled-release fertilizer formulations on rice yield, ammonia volatilization and greenhouse gas emissions. A field experiment was conducted using rice cultivar Nangeng5718 in two types of soil texture（sandy and clay soil）, and set up a conventional fertilization as control（CK）and four slow/controlled-release fertilizer formulations：sulfur-coated slow-release blended urea（T1）, resin-coated controlled-release urea Ⅰ + ordinary urea（T2）, resin-coated controlled-release urea Ⅱ（T3）, resin-coated controlled-release urea Ⅰ + ordinary urea + nitrification inhibitor（T4）. Results showed that rice yield was decreased in sandy and clay soils under T1 treatment compared with that of CK treatment, whereas T2-T4 treatments increased rice yield by 3.35%-18.33% and 2.40%-9.64%, respectively. Specifically, rice yield increased the most under T3 treatment, which increased by 18.33% and 9.64% in sandy and clay soils, respectively. Compared with T1 treatment, T2-T4 treatments reduced ammonia volatilization by 62.13% - 69.97% and 12.16% - 47.76% in sandy and clay soils, respectively. Among them, the addition of nitrification inhibitor treatment（T4）increased ammonia volatilization loss by 26.11% and 68.16% in sandy and clay soils, respectively, compared with the unadded treatment（T2）. The T2-T4 treatments reduced CH4 emissions by 17.09%- 45.60% and 0.99%- 31.24% in sandy and clay soils, respectively, compared with T1 treatment. Among them, the addition of nitrification inhibitor treatment（T4）was able to reduce CH4 and N2O emissions from paddy fields by 12.11% and 0.99% for CH4 and 51.87% and 42.50% for N2O in sandy and clay soils, respectively, compared to the unadded treatment（T2）. In summary, T2-T4 treatments were able to achieve flat or increased rice yields compared to CK treatment in both sandy and clay soils and showed significant advantages in reducing ammonia volatilization and greenhouse gas emissions from paddy fields compared to T1 treatment. T3 treatment applied in clay soils was able to increase rice yields and effectively reduce ammonia volatilization, CH4 and N2O emissions from paddy fields. |
