Effects of Tillage and Grass Intercropping on Soil Respiration in Citrus Reticulate Orchard

Abstract

Abstract: The soil respiration under the conditions of tillage and grass intercropping in Citrus reticulate Orchard in Fuzhou were measured continuously with LI-8100 automated soil CO2 flux system on October,2007.It could provide some references for researching agricultural greenhouse.The results showed that tillage significantly made soil respiration rate increase in citrus orchard ecosystem.Soil respiration increased by 49.0% in the field experiment.Although soil respiration increased by 26.24% by intercropping grass in orchard,but carbon storage of the ecosystem also increased by 3400.0kg·ha-1.

Key words: Orchard, Tillage, Grass intercropping, Soil respiration
