摘要: 为了探明适用于常山胡柚不同时期的专用肥配方及其对产量、品质、温室气体排放和土壤肥力的影响,本研究设置了4种施肥模式:CK,不施肥;FP,农户常规施肥;OPT,优化施肥;OPT50%N,在优化施肥的基础上施氮量减半。采用静态箱气相色谱法监测1年生育期内(2023年3月10日—2024年1月11日)的温室气体(N2O和CH4)排放。结果发现,与FP处理相比: OPT处理的果实产量未显著下降,果实品质提升,可滴定酸度显著(p<0.05)降低21.6%,固酸比和可食率分别显著提升27.7%、2.37百分点,CH4累积排放量和温室气体排放强度(GHGI)分别显著降低30.8%和33.3%,同时能够保证土壤有效养分的供给。OPT50%N处理虽然也能维持较高的果实品质和土壤有效养分的供给,且N2O累积排放量和CH4累积排放量较较FP处理分别显著降低30.9%、61.5%,但果实产量亦显著下降4.52%。综上,OPT处理既能保证果实产量,还能实现提质减排协同,可以开发为专用肥产品。该处理的化肥养分总投入量较FP减少24.4%,有效实现了化肥的减量增效。

Abstract:

To explore the special fertilizer formulas suitable for Citrus×aurantium L. Changshanhuyou at different growth stages and their effects on yield, quality, greenhouse gas emissions, and soil fertility, this study established four fertilization modes: CK (no fertilization), FP (farmers’ conventional fertilization), OPT (optimized fertilization) and OPT50%N (optimized fertilization with nitrogen application rate reduced by 50%). The static chamber-gas chromatography method was employed to monitor the emissions of greenhouse gases (N2O and CH4) throughout the growth period within one year (from March 30th, 2023 to January 11th, 2024). The results showed that compared with the FP treatment: the OPT treatment did not cause a significant decrease in fruit yield while improving fruit quality, with titratable acidity significantly (p<0.05) reduced by 21.6%, ratio of total soluble solids content to titratable acidity and edible rate significantly increased by 27.7% and 2.37 percentage points, respectively; cumulative CH4 emission and greenhouse gas intensity (GHGI) were significantly reduced by 30.8% and 33.3%, respectively; and the supply of soil nutrients in soil was guaranteed. Although the OPT50%N treatment also maintained fruit quality and the supply of available nutrients in soil, with cumulative N2O emission and CH4 emission significantly reduced by 30.9% and 61.5% than those of FP treatment, respectively, the fruit yield was significantly decreased by 4.52%. In conclusion, the OPT treatment could not only ensure fruit yield but also achieve the coordination of quality improvement and greenhouse gas emissions reduction, and thus could be developed into a special fertilizer product. The total nutrients input of chemical fertilizers in this treatment was reduced by 24.4% compared with FP, which effectively realized the usage reduction and efficiency improvement of chemical fertilizers.
