Research in the Hongsibu District of Ningxia has shown that vineyards, specifically Vitis vinifera 'Cabernet Sauvignon', can effectively serve as a carbon sink, with most carbon being stored in the soil and perennial vine organs. This suggests that vineyards have the potential to capture and store carbon, contributing to overall efforts to reduce greenhouse gas emissions.
Given that the global winegrape planting area is 7.2 x 10(6) hm(2), the potential for winegrape crop-mediated carbon capture and storage as an approach to reducing greenhouse gas emissions warranted further research. Herein, we employed an allometric model of various winegrape organs to assess biomass distributions, and we evaluated the carbon storage distribution characteristics associated with vineyard ecosystems in the Hongsibu District of Ningxia. We found that the total carbon storage of the Vitis vinifera 'Cabernet Sauvignon' vineyard ecosystem was 55.35 t center dot hm(-2), of which 43.12 t center dot hm(-2) came from the soil, while the remaining 12.23 t center dot hm(-2) was attributable to various vine components including leaves (1.85 t center dot hm(-2)), fruit (2.16 t center dot hm(-2)), canes (1.83 t center dot hm(-2)), perennial branches (2.62 t center dot hm(-2)), and roots (3.78 t center dot hm(-2)). Together, these results suggested that vineyards can serve as an effective carbon sink, with the majority of carbon being sequestered at the soil surface. Within the grapevines themselves, most carbon was stored in perennial organs including perennial branches and roots. Allometric equations based on simple and practical biomass and biometric measurements offer a means whereby grape-growers and government entities responsible for ecological management can better understand carbon distribution patterns associated with vineyards.
