摘要: 为给柑橘园的低碳发展提供科学依据,本文以浙江省衢州市柑橘园为研究对象,采用生命周期评价方法,针对投入品生产运输、田间施肥管理和果园固碳等建立柑橘园碳核算方法,并对衢州市柑橘园的碳排放和碳储量现状进行评价。结果表明:衢州市柑橘园以≥20年树龄为主,平均产量为43.35 t·hm-2;单位面积碳排放总量(以CO2当量计)为7.61 t ·hm-2,其中,氮肥生产运输排放的占比最大,为41.66%;单位面积碳储量为66.18 t·hm-2。0~30 cm土层的土壤碳储量是碳汇的主体,占87.43%。不同树龄柑橘园的碳排放和碳储量有所差异,主要与不同树龄果园的施肥和管理差异有关。未来,应进一步优化果园管理,通过减少化肥施用和增加有机肥替代比例,进一步提升柑橘园的减排固碳能力。

Abstract:

To provide a scientific basis for the low-carbon development of citrus orchards, the citrus orchards in Quzhou City, Zhejiang Province of China were selected as the research object, and the life cycle assessment method was adopted in the present study. A carbon accounting method for citrus orchards was established, which covered the production and transportation of input materials, field fertilization management, and orchard carbon sequestration. On this basis, the current status of carbon emissions and storage of citrus orchards in Quzhou City was evaluated. The results showed that: the citrus orchards in Quzhou City were mainly composed of citrus trees with an age of ≥20 years, and the average yield was 43.35 t·hm-2. The total carbon emissions per unit area (calculated as CO2 equivalent) was 7.61 t·hm-2, among which the emissions from the production and transportation of nitrogen fertilizer accounted for the largest proportion (41.66%). The carbon storage per unit area was 66.18 t·hm-2, and the soil carbon pool in the 0-30 cm soil layer was the main body of carbon sink, accounting for 87.43%. There were differences in carbon emissions and carbon storage among citrus orchards of different tree ages, which were mainly related to the differences in fertilization and management practices among orchards. In the future, orchard management should be further optimized by reducing chemical fertilizer application and increasing the proportion of organic fertilizer substitution, to further improve the carbon emissions reduction and carbon sequestration capacity of citrus orchards.
