以往的研究表明，蔬菜种植增加土壤有机碳（SOC）储量。然而，如何稳定的SOC增量是，以及如何温室栽培贡献SOC增量的数量和稳定性，目前尚不清楚。土壤样品取自三种典型的蔬菜种植模式：露地（OF），季节性温室（SG），永久性温室（PG），以及相邻的非蔬菜领域。将有机碳库分为活性库（Ca）、慢活性库（Cs）和抗性库（Cr），以评价蔬菜种植中有机碳的固定及其稳定性。结果表明，蔬菜种植与更大的存储SOC相比，非蔬菜种植（SOC平均增加了57.9%）。以非蔬菜地为参照，蔬菜种植增加的土壤有机碳中Ca的比例（3.7-6.6%）高于参照地（1.0-2.0%），表明蔬菜种植增加的土壤有机碳容易分解。在三种蔬菜种植模式中，SG由于其相对稳定的SOC固存能力而被推荐，其中Cr的增加量较高。总体而言，蔬菜种植可以提高土壤有机碳的含量，但蔬菜种植方式影响土壤有机碳增量的稳定性。
Previous studies suggest that vegetable cultivation increases soil organic carbon (SOC) storage. However, how stable the SOC increment is, and how greenhouse cultivation contributes to the SOC increment in terms of quantity and stability, remains unclear. Soil samples were taken from three typical vegetable cultivation pattern fields: open field (OF), seasonal greenhouse (SG), and permanent greenhouse (PG), as well as adjacent non-vegetable fields. Three conceptual SOC pools, including active (Ca), slow (Cs), and resistant (Cr) pools were fractionated to evaluate SOC sequestration and its stability in vegetable cultivation. The results indicate that vegetable cultivation is associated with greater stored SOC compared with non-vegetable cultivation (SOC increased by 57.9% on average). Using non-vegetable fields as a reference, SOC increments by vegetable cultivation were associated with a higher proportion of Ca (3.7–6.6%) than the reference fields (1.0–2.0%), indicating that the SOC increments might be easily decomposed. Among the three vegetable cultivation patterns, SG, with a higher increase in Cr, is recommended due to its relatively more stable SOC sequestration. Overall, vegetable cultivation could enhance the quantity of SOC, but the stability of the SOC increment is affected by the vegetable cultivation pattern.
