| 中文摘要: |
| 为探讨不同施肥管理对西瓜产量、温室气体排放及土壤理化性质等的影响，确定适宜的施肥方式，以期达到西瓜高产、减排的目的。试验以大棚西瓜田为研究对象，根据底肥施用方式设置5种处理：不施用肥料（CK）、常规施肥（CT+OM）、测土配方施肥（ST+OM）、单施有机肥（OM）、单施化肥（UF）。采用静态箱-气相色谱法采集分析西瓜田温室气体排放通量，同时对土壤无机氮及有机质进行检测。结果表明：有机肥配施无机肥处理西瓜产量提升明显，其中ST+OM处理西瓜产量显著高于其他处理，相比于CK显著增加143.78%，在西瓜幼苗期，CT+OM、ST+OM及OM处理的土壤铵态氮含量及有机质含量显著高于其他处理；CT+OM处理相较于其他处理N2O及CO2的排放通量整体变化幅度最大，CH4排放通量呈正负交替波动变化；CT+OM处理温室气体排放强度显著高于UF，与其他处理无显著差异。研究表明，测土配方施肥处理相比于其他处理能够显著提高西瓜产量，且其温室气体排放强度与最低的单施化肥处理无显著差异，为综合效益最佳的施肥模式。 |

| To explore the effects of different fertilizer management on watermelon yield, greenhouse gas emission and soil physicochemical properties, etc., and to explore the determination of suitable fertilizer application methods, to achieve high watermelon yield and emission reduction. The experiment was conducted in a greenhouse watermelon field, and five treatments were set up according to the bottom fertilizer application method：no fertilizer（CK）, conventional fertilizer application（CT+OM）, soil testing and formulation（ST+OM）, single application of organic fertilizer（OM）, single application of chemical fertilizers（UF）, and the greenhouse gas emission fluxes in the watermelon field were collected and analyzed by static box-gas chromatography, and the fluxes of soil inorganic nitrogen and organic matter were detected. The results showed that the watermelon yield of organic fertilizer with inorganic fertilizer was significantly increased, among which the watermelon yield of ST + OM treatment was significantly higher than that of other treatments, with a significant increase of 143.78% compared with that of CK. In the seedling stage of watermelon, the ammonium nitrogen content of the soil and the content of organic matter of CT+OM, ST+OM, and OM treatments were significantly higher than that of other treatments; CT+OM had the largest overall change in NO2 and CO2 emission fluxes compared to the other treatments and CH4 emission fluxes showed positive and negative alternating fluctuations; the intensity of greenhouse gas emissions was significantly higher in the CT+OM treatment than in the UF, and there was no significant difference in the other treatments. Soil testing and formulated fertilization treatments were able to significantly increase watermelon yields compared to other treatments, and their greenhouse gas emission intensities were not significantly different from the lowest single fertilizer treatment, making them the best fertilizer application model in terms of overall benefits. |
