In order to comprehend the temporal and spatial variations in the quantity of crop straw resources in the Yangtze River Economic Belt over the past decade, as well as the estimated carbon emission reduction potential from straw biochar, the straw coefficient method was employed to scientifically estimate the crop straw resources in the region from 2011 to 2020. The study analyzed the spatiotemporal distribution characteristics of straw resource density and per capita resource quantity. Furthermore, it estimated the carbon emission reduction potential of preparing biochar from straw. The results indicate that the total amount of crop straw in the Yangtze River Economic Belt increased by 0.22×10 8 t from 2011 to 2020. In 2020, the theoretical total amount of crop straw resources in the region was approximately 3.04×10 8 t. The overall net potential for greenhouse gas mitigation was an emission reduction of approximately 2.18×10 8 t of CO 2e . It is evident that converting crop straw into biochar holds significant potential and serves as an effective means to achieve carbon emission reduction.
为了解长江经济带近十年来农作物秸秆资源量的时空变化以及秸秆生物炭的碳减排潜力，采用秸秆系数法对该地区2011-2020年的农作物秸秆资源量进行了科学估算。研究分析了秸秆资源密度和人均资源量的时空分布特征。此外，研究还估算了利用秸秆制备生物炭的碳减排潜力。结果表明，从 2011 年到 2020 年，长江经济带农作物秸秆总量增加了 0.22×10 8 t。2020 年，该地区农作物秸秆资源理论总量约为 3.04×10 8 t，温室气体减排总净潜力约为 2.18×10 8 t CO 2e。由此可见，将农作物秸秆转化为生物炭潜力巨大，是实现碳减排的有效手段。

Drought, a significant abiotic stressor, exerts harmful effects on crop productivity on a global scale. Researchers have investigated various strategies aimed at mitigating the detrimental impacts of drought on crop productivity. Biogas slurry (BGS) improves soil fertility and water retention, leading to increased crop output. The study aims to assess how biogas slurry improves wheat crop development and yield during drought stress. A pot experiment was carried out at the agronomic research area of IUB Bahawalpur to investigate the effect of biogas slurry on wheat crop growth under restricted water availability. The present study employed four distinct treatments of biogas slurry, namely T 0 (control), T 1 (450 kg ha -1 ), T 2 (550 kg ha -1 ), and T 3 (650 kg ha -1 ), in conjunction with the imposition of drought conditions. The results of the study suggest that the presence of drought conditions during the grain-filling phase exerts a negative influence on the final yield outcome. Furthermore, it was observed that biogas slurry at a dosage of 650 kg ha -1 has a pronounced impact on both the growth and yield of the cultivated crop. Soil amendment of biogas slurry at a 650 kg ha -1 rate yielded notable improvements in multiple plant growth parameters. The experimental results indicate a remarkable (6.18%) elevation in plant height, a substantial (13.26%) augmentation in the count of fertile tillers, a significant (6.90%)
干旱是一种重要的非生物压力源，在全球范围内对作物生产力产生有害影响。研究人员调查了各种旨在减轻干旱对作物产量有害影响的策略。沼气浆（BGS）可提高土壤肥力和保水性，从而提高作物产量。这项研究旨在评估沼气浆如何在干旱胁迫下改善小麦的生长发育和产量。在 IUB Bahawalpur 的农艺研究区进行了一项盆栽实验，以研究沼气浆对水分供应受限情况下小麦作物生长的影响。本研究采用了四种不同的沼气浆处理，即 T 0（对照）、T 1（450 千克/公顷-1）、T 2（550 千克/公顷-1）和 T 3（650 千克/公顷-1），同时施加干旱条件。研究结果表明，在谷物灌浆期出现干旱条件会对最终产量产生负面影响。此外，研究还发现，沼气泥浆的用量为 650 千克/公顷-1，对种植作物的生长和产量都有显著影响。以每公顷 650 千克的用量添加沼气泥浆对土壤进行改良后，植物的多个生长参数都有明显改善。实验结果表明，植株高度明显提高（6.18%），肥沃分蘖数大幅增加（13.26%），茎秆粗壮程度显著提高（6.90%），茎秆粗壮程度显著提高（6.90%），茎秆粗壮程度显著提高（6.90%）。

Carbon xerogel is a nano-scale adsorption material with abundant mesopores and large adsorption capacity. A series of mesoporous carbon xerogels (MCX) were synthesized in the process of polycondensation of resorcinol and formaldehyde using different resorcinol/sodium carbonate catalyst molar ratios (R/C = 100~3000). And the adsorption behavior of the MCX for the azo dye reactive blue 13 (RB13) from dyeing wastewater was investigated in this study. Results showed that variations in both specific surface area and pore size distribution of MCX were closely related to the amount of catalyst. The MCX exhibited maximal surface area, abundant mesoporosity, and highest adsorption capacity for RB13 when the molar ratio of R/C was 1000. The adsorption of RB13 by MCX1000 proceeded rapidly in the first 50 min and reached equilibrium in 180 min. The adsorption process was exothermic, spontaneous, and can be well fitted by the pseudo-second-order and Temkin models, with the maximum sorption capacity of 184.36 mg·g -1 . The adsorption of RB13 onto MCX was attributed to physicochemical adsorption. The main adsorption mechanisms of the MCX for RB13 were the electrostatic interaction, hydrogen bonding and van der Waals forces between dye molecules and functional groups, such as -OH, and -C-O, etc.

Sesame is a historic oilseed crop cultivated globally. The crop harbors natural antioxidants in plant tissues, including leaves, stems, and seeds. Understanding flower development mechanisms is crucial for higher yield and quality. However, the physiological and molecular aspects of three-and single-capsule flower development in sesame remain unexplored. This study investigated the transcriptome during sesame flower development, focusing on three-capsule (Arslanbey) and single-capsule (Hatipoğlu) cultivars during 2017-2018. Physiological analyses (iron chelation, DPPH, FRAP) and qRT-PCR of APETALA1, APETALA2, SPL4, SOC1, AT4G37770, SILPT3, and beta-glucosidase genes were conducted. Metal-iron chelation, FRAP, and DPPH in leaf tissues indicated higher values in the single-capsule cultivar, while catalase and peroxidase activity were higher in the three-capsule cultivar. Expression analyses at different weeks post-flowering showed peak levels for AP1, AP2, SPL4, SILPT3, and beta-glucosidase at 8W-H (8th-Hatipoğlu) in the single-capsule cultivar, and for SOC1 and AT4G37770 at 9W-H (9th-Hatipoğlu). Capsule-related gene expression over 9 weeks revealed 8W-H (8 th -Hatipoğlu). As abundant for APETALA1, APETALA2, SPL4, SILPT3, and beta-glucosidase, while 9W-H (9 th -Hatipoğlu) was abundant for SOC1 and AT4G37770. In this study, which was carried out to examine the factors affecting the encapsulation status of single-capsule and three-capsule sesame varieties, evaluations were made based on the data obtained as a result of the observations and analysis. All analyses have shown that the single and triple encapsulation phenomena are quite complex and depend on multiple gene mechanisms and multiple biochemicals. In summary, our study unveils the intricate genetic and biochemical factors influencing capsule development in single-capsule and three-capsule sesame varieties. These findings offer valuable insights for future breeding strategies and molecular studies in sesame and related crops.

Grass-Planting Concrete (GPC) represents a novel eco-friendly concrete material with distinct physical and chemical differences compared to regular soil. The response of plant roots to the growth environment provided by GPC is poorly understood. This study explores the strategies plants employ in response to the stress imposed by GPC environments. Ryegrass is the focal point in this study, utilizing planting experiments. Geometric morphological parameters, fractal dimensions, and topological indices of root during three growth stages (elongation stage, heading stage, and fruiting stage) were measured and calculated. The study analyzes changes in the configuration characteristics of ryegrass root systems in GPC and soil media. Experimental results suggested that: 1) The morphological parameters of ryegrass root systems in GPC are greater than those in soil, particularly during the elongation stage, with a notably higher degree of branch expansion in GPC media. 2) Root system configuration parameters in both media are positively correlated with the total root surface area. The correlation between configuration parameters and branch density, number of branches, etc., is more robust in GPC media. 3) The total root length distribution decreases with depth in both media. In GPC media, the peak total root length occurs in the 2~4 cm range, with deeper rooting reaching up to 16 cm during the elongation stage. The stress effect of GPC was weakened over time. Plants enhance their adaptive capabilities by strategically altering their morphological and structural characteristics. The research findings provide theoretical and technical support for optimizing the structure and vegetative performance of GPC.

To analyze the global sensitivity of winter wheat parameters using the AquaCrop model on a global scale, the extended Fourier amplitude sensitivity test (EFAST) was utilized to identify parameter sensitivity differences in different regions and meteorological conditions represented by eight stations in Henan Province, including Zhengzhou, Anyang, Shangqiu, Luanchuan, Nanyang, Xuchang, Zhumadian, and Xinyang. The results showed that: (1) the sensitivity of crop parameters is little affected by meteorological conditions for biomass, and the sensitivity parameters of the eight regions were consistent; there were minimum growing degrees required for total biomass production ( stbio ), normalized water productivity ( wp ), maximum canopy cover in fraction soil cover ( mcc ), crop coefficient when the canopy was complete but prior to senescence ( kcb ), Growing degree-days (GDD)-from sowing to emergence ( eme ), and GGD-increase in canopy cover ( cgc ); (2) for canopy cover, the most sensitive parameters were mcc , cgc , soil surface covered by an individual seedling at 90% emergence ( ccs ), and other parameters were more sensitive in early growth stage of winter wheat; (3) for yield, GDD-from sowing to flowering ( flo ) was the most sensitive parameter. The results of this study will provide support for the use of the AquaCrop model to investigate crop management at the local level.

The government and academic community have widespread concerns about how China utilizes financial resources to direct credit allocation and achieve high-quality economic development, especially under the dual pressures of resource constraints and environmental challenges. Analyzing panel data from 30 Chinese provinces from 2008 to 2020, this paper constructs evaluation indicators of high-quality economic development and aims to explore the impact of green credit on such development. The study concludes that green credit significantly contributes to high-quality economic development. This effect varies based on regional location, bank competition levels, the development quality of intermediary organizations, and local government debt pressure. In terms of mechanisms, the advancement of green technology, industrial structure upgrading, and energy consumption structure adjustment emerge as key transmission mechanisms. The findings underscore the importance of actively promoting green credit, steadily increasing green finance initiatives, and skillfully directing capital flows toward resource-and technology-efficient, environmentally-friendly businesses. This approach is essential to accelerate the shift in the economic development model and foster the growth of a green economy.

Renewable energy is absolutely necessary in order to stop the deterioration of the environment and to guarantee reliable access to environmentally friendly energy sources. Based on the conformity theory, logistic regression, propensity score matching, and stepwise regression are all used in the current study to investigate the mediating role of green intentions in the conformity tendencies of Chinese farmers’ adoption of renewable energy sources. This research was motivated by the notion of the dissemination of innovations as well as the technological adoption model, and it aims to shed light on how individuals are socialized and how green intentions mediate their conformity tendencies to adopt renewable energy sources. The results revealed that the average age of the farmers was 42 years, and they were primary school graduates. More than 50% were male. Almost 26% of farmers reported that they use renewable energy sources on their farms. Generally, the farmers were green intended and would like to adopt renewable energy sources. The regression results disclosed a significant impact of socially inspired peer adoption (p<0.01) on the farmers’ adoption of renewable energy sources. Renewable energy adoption is impacted more by the adoption of strong connections than by the adoption of renewable energy by weak relations, which means that farmers are more likely to adopt renewable energy if their peers also do so. Nevertheless, the extent to which farmers have green intentions regarding the use of renewable energy technology had a significant influence on the farmers’ conformity tendencies, influenced by the different intensities of their social networks.

The treatment of municipal solid waste (MSW) in Peru and some parts of the world is still incipient, mainly due to the lack of technologies implemented to recover this waste; another important cause in Peru is the lack of studies for the treatment of the organic fraction of municipal solid waste (OFMSW). The objectives of this work were: (i) to determine the generation of OFMSW, (ii) to produce quality compost and (iii) to estimate the application rate for the recovery of degraded surfaces. Tools and instruments acquired from the Institute of Sanitary Engineering of FIUBA and the Ministry of the Environment were used to measure physicochemical parameters and environmental estimates. The results showed a per capita MSW generation of 0.472 kg/inhab/day, of which 42.87% was composed of OFMSW or organic fraction of MSW; a feasible availability of organic matter for composting of 6783.79 t/year was determined. The composting experiment was carried out with waste segregated at the MSW treatment plant, installing composting piles

While promoting economic development, the tourism industry has also significantly increased carbon emissions, causing certain environmental damage. Currently, the carbon emissions issue of rural tourism has gradually become a hot topic of concern. As one of the burgeoning rural tourism destinations in China, Songkou Town holds significant relevance and serves as a valuable reference point for examining carbon emissions in this sector. Consequently, this study leverages pertinent theoretical advancements in carbon emissions research to establish a comprehensive theoretical framework encompassing rural tourism carbon sources, carbon emissions systems, estimation methodologies, and proposes appropriate carbon compensation strategies. The study focuses on Songkou Town as the subject of empirical analysis and conducts a comprehensive examination of its carbon emissions sources. The findings revealed that among the various sources of carbon emissions in rural tourism within Songkou Town, the highest carbon emissions was attributed to tourism transportation, amounting to 9700.1 t. Conversely, the management department exhibited the lowest carbon emissions, with a recorded value of 11.455 t. The proportion of rural tourism transportation, tourism accommodation, tourism catering, shopping and entertainment, garbage disposal, management departments, and residents’ living in Songkou Town to the total carbon emissions was 55.60%, 0.35%, 1.56%, 3.93%, 13.59%, 0.07%, and 24.91%, respectively. This study conducted a comprehensive assessment of carbon emissions in Songkou Town and examined the carbon compensation mechanism of rural tourism from a micro-level perspective. The findings hold significant practical implications for local rural tourism planning and sustainable development. Moreover, the study also offers valuable insights and guidance for promoting regional development and ensuring the successful implementation of carbon compensation measures.
