The results indicate that annual total precipitation, 1 day 5 maximum extreme days over 95th 99th percentiles trended upward Spatially, stations experienced significant positive six indices are mostly distributed eastern basin, while those negative a few...

Downy mildew is a major threat to viticulture, leading severe yield loss. The use of traditional copper-based fungicides effective, but has adverse effects on the environment and human health, making it urgent develop an environmentally friendly disease management program. Multi-functional kaolin particle film (KPF) promising as effective safer treatment strategy, since this material lacks chemically active ingredients. In study, ability Kaolin pretreatment protect grapevine leaves from...

Due to the particularity of continental monsoon climate in China, more than 90% wine grape cultivation areas require vines be buried winter for a burial period that can extend half year. Additionally, traditional vine practices expose surface soil during winter, easily leading erosion. To meet restrictive factors viticulture Chinese cold zone, new sustainable strategy called crawled cordon mode (CCM) has been developed. CCM includes training (CCT), physical methods flower and fruit thinning,...

Kaolin particle film (KPF) is an aqueous formulation of chemically inert mineral particles that can be sprayed on the surface crops to form a protective film, resulting in increased fruit yield and quality. In this work, effects kaolin-based, foliar reflectant grape composition volatile compounds ‘Meili’ ( Vitis vinifera L.) grapes were investigated under different growth stages over two growing seasons. The 100-berry weight titratable acid content decreased, sugar soluble solid contents...

Land desertification is a global environmental problem, leading to the deterioration of ecological environment and an issue that threatens humans. Hongsibu, located in Ningxia, northwest China, semi-desert area with largest domestic single-site resettlement for poverty alleviation based on wine industry. Here, we quantified value ecosystem services industry Hongsibu used analytic hierarchy process (AHP) quantitatively evaluate comprehensive benefits resolving desertification. We found...

Given that the global winegrape planting area is 7.2 × 106 hm2, potential for crop-mediated carbon capture and storage as an approach to reducing greenhouse gas emissions warranted further research. Herein, we employed allometric model of various organs assess biomass distributions, evaluated distribution characteristics associated with vineyard ecosystems in Hongsibu District Ningxia. We found total Vitis vinifera ‘Cabernet Sauvignon’ ecosystem was 55.35 t·hm−2, which 43.12 t·hm−2 came from...

With the extreme changes of global climate, winter freezing injury has become an important limiting factor for development grape industry. Therefore, there is a significant need screening cold-resistant wine germplasms and cold regionalization breeding grapevine cultivation in regions. In this study, low-temperature half-lethal temperature (LT50) values were determined annual dormant branches 124 (V. vinifera) to evaluate their resistance. The LT50 tested ranged from −22.01 °C −13.18 °C,...

Abstract Soil organic nitrogen (SON) accounts for more than 90% of the total (TN) in black soil and is one most important indicators fertility. However, effect land‐use changes on SON fractions still unclear soil. Hence, natural grassland (uncultivated), farmland (converted from grassland), artificial forestland (grain plots converted into forests) region Northeast China were selected research. TN, available (AN) (ammonia (AMN), amino acid (AAN), hydrolysable unknown (HUN), insoluble (AIN))...

Challenges arise in global viticulture due to low temperatures. To ensure the sustainable and high-quality development of wine industry, it is essential breed grape varieties that are not only high quality but also possess cold hardiness. Intraspecific recurrent selection Vitis vinifera can enhance hardiness while maintaining fruit quality. In this study, we used 'Ecolly 'as an intermediary variety for crossing with 'Cabernet Sauvignon', 'Marselan', 'Dunkelfelder', including three reciprocal...

Most cultivars of Vitis vinifera L. are very sensitive to cold. As an exogenous protectant, Biodegradable Liquid Film (BLF) is considered protect winegrapes from low temperatures and dry winds for safe overwintering. This study aimed reveal the physiological biochemical mechanisms BLF regulating freezing tolerance wine grapes. Groups ten-year-old vines (Cabernet Sauvignon) were sprayed with in November 2020 2021, or left untreated as a control treatment, field plant mortality after...

Abstract The efficient etherification of 2,5‐bis(hydroxymethyl)furan (BHMF) to 2,5‐bis(propoxymethyl)furan (BPMF) was achieved by using low‐cost amorphous silica‐aluminas (ASA) catalysts in a fixed‐bed reactor. A considerable yield BPMF up 85.1 % obtained over ASA‐30 catalyst under the reaction conditions 140 °C, 2.0 MPa N 2 , and 0.015 h −1 WHSV. excellent performance could be attributed relatively stronger acidity (>375 °C) larger mesoporous size (6 nm), thereby facilitating conversion...

Winegrape cultivation has become increasingly common throughout northwest China over the past 20 years, and such viticulture can profoundly impact properties of utilized soil associated microbial communities. To explore these effects in present study, samples were collected from control desert vineyards planted different years: Cabernet Sauvignon (CS, 2014), Merlot (M, 2012), Italian Riesling (IR, 2008). The this communities therein assessed through a series physicochemical, enzymatic,...

The influence of interphase on the level and distribution thermal residual stress (TRS) in SiCp/6061Al composites was studied by using a three-dimensional (3D) interface-phase model. expansion coefficient elastic modulus components were main factors affecting TRS composites. formed SiC-MgO-6061Al has highly concentrated TRS, SiC-Si-6061Al had lowest level. With increase thickness, for most components, showed trend first decreased then increased. When thickness 1.2 μm, it SiC particle aspect...

Biodegradable liquid film (BLF) improves soil structure and increases plant freezing tolerance after spraying on the surface of plant. In this study, effects BLF grape composition volatile compounds in Cabernet sauvignon (Vitis vinifera L.) grapes were determined by during dormant periods over three years. The aim study was to evaluate potential impact as an overwintering protection measure fruit quality. 2020 2021, increased reducing sugar content 100-berry weight, decreased titratable acid...

The staking (elevating creeping vines above the ground with poles) of yam is practiced to optimize crop yield, but its effect on soil loss due harvesting (SLCH-soil adhering harvested tubers) and associated carbon has not been investigated globally. A 3-year field experiment was conducted study (Dioscorea rotundata) SLCH examine environmental loss. Staking reduced by 55.6% increased yield 33.3% when compared un-staking. Soil root hair weight per tuber decreased 47.7 58.4%, respectively,...
