不同绿肥施用量对柑橘果园土壤有机碳矿化的影响

omparing with the blank treatment, both the SOC mineralization speed and the accumulative mineralization in the green manure treatments increase significantly. SOC potential to mineralize, SOC easy to mineralize, and the initial potential carbon mineralization speed obtained from the first-order kinetic model also increase significantly with the application amount of green manure. In the first 8 days, the differences among the treatments with different amount green manure are notable, and comparing with the blank treatment, the difference are notable too; The order of SOC accumulative mineralization is: fertilizing with full green manure > green manure and chemical fertilizer > single chemical fertilizer ≈ without fertilization; the proportion of potential carbon mineralization to TOC ranks in the order: without fertilization > fertilizing with single chemical fertilizer > green manure and chemical fertilizer > full green manure.
