Carbon Storage Distribution Characteristics of Vineyard Ecosystems in Hongsibu, Ningxia

Abstract

Given that the global winegrape planting area is 7.2×106 hm2, 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·hm−2, of which 43.12 t·hm−2 came from the soil, while the remaining 12.23 t·hm−2 was attributable to various vine components including leaves (1.85 t·hm−2), fruit (2.16 t·hm−2), canes (1.83 t·hm−2), perennial branches (2.62 t·hm−2), and roots (3.78 t·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.

Biochar from Grapevine-Pruning Residues Is Affected by Grapevine Rootstock and Pyrolysis Temperature

“…Increasing pyrolysis peak temperature significantly increased biochar TC content, probably due to volatilization losses of other elements, especially H and O, and confirmed results reported by Ippolito et al [46]. The average TC content in grapevine pruning residues was 44.5%, which is similar to other studies [49][50][51], where authors reported values from 44.1% to 47.8%. In biochar, the average TC content was 75.4%, which agrees with the results of other studies (73.5%) [50], while a recent study reported even lower TC content (69.4%) [52].…”

Effect of Solar Farms on Soil Erosion in Hilly Environments: A Modeling Study From the Perspective of Hydrological Connectivity

“…The site (37°61′N, 106°12′E; 1,350 m a.s.l.) is located in a hilly landscape (part of the Yellow River Basin, administratively belonging to Wuzhong, China) at an elevation of 1,240–1,450 m, in the Loess Plateau of China (Figure 3a) (Zhang et al., 2021). This area has a typical temperate continental arid climate with an annual average temperature of 9.2°C (maximum daily temperature of 29.7°C and minimum daily temperature of −14.2°C).…”

“…This study was carried out at the Hongsibu solar farm (37°61'N, 106°12'E; 1350 m a.s.l.) located in a hilly landscape (part of the Yellow River Basin, administratively belonging to Wuzhong, China) at an elevation of 1240-1450 m, in the Loess Plateau of China (Figure 1a) (Zhang et al, 2021). This area has a typical temperate continental arid climate with an annual average temperature of 9.2 °C (maximum daily temperature of 29.7 °C and minimum daily temperature of -14.2 °C).…”
