 摘要： [Objectives] To explore the spatiotemporal evolution and development drivers for Taobao villages in Cao County. [Methods] This paper employs GIS spatial analysis methods such as standard deviation ellipse and kernel density to characterize the spatial distribution, agglomeration, and correlation features of Taobao villages in Cao County at the township scale. Additionally, geographic detectors are used to explore influencing factors. [Results] (i) The number of Taobao villages in Cao County exhibits phased characteristics, progressing through initial, rapid expansion, and stable development stages. (ii) Taobao villages are unevenly distributed, with significant clustering features, primarily concentrated in the southeastern part of the county. In recent years, they have expanded toward the central and northwestern regions, potentially forming a "multi-core" spatial pattern in the future. (iii) The number of garment industries and e-commerce industrial parks consistently remains the primary factor influencing the spatial distribution of Taobao villages. After 2020, the number of wood processing industries and specialty agricultural product processing industries also exerted considerable influence. The number of logistics parks began to have an impact after 2018, albeit a weak one. Other factors had minimal influence on the differentiation of Taobao villages. [Conclusions] The spatiotemporal evolution exhibited diffusion along the "northwest-southeast" axis, with strengthened regional clustering. Government policies and industries significantly influenced the differentiation of Taobao villages, with varying primary factors across different periods.

 摘要： Investigation and analysis of the current status of farmers’ livelihood capital and promptly discovering and solving problems in farmers’ livelihood development are of great practical significance for optimizing farmers’ livelihood strategies and enhancing farmers’ livelihood sustainable development capability. Based on the framework of sustainable livelihood analysis, taking Yangshan County as an example, this paper uses field surveys, questionnaires and interviews to summarize and analyze the current status and characteristics and main problems of local farmers’ livelihood capitals on the basis of the data of 628 farmer samples. It proposes countermeasures for future development of farmers’ livelihoods. Implementing these strategies will be helpful for improving the livelihoods capital structure of farmers’ and enhancing their sustainable development capability.

 摘要： Taking Zhejiang Province as an example, this paper explores the mechanisms and implementation pathways through which the low-altitude economy drives the transformation and upgrading of the tourism industry. It finds that the low-altitude economy can effectively promote the development of high-end and diversified tourism in Zhejiang by innovating tourism formats, optimizing resource allocation, and enhancing tourist experiences. Besides, it analyzes the current development status of the low-altitude economy in Zhejiang and its potential for integration with tourism, revealing specific enabling pathways for tourism transformation, including low-altitude sightseeing, aviation tourism, and low-altitude sports. Finally, it proposes policy recommendations such as strengthening policy support, enhancing infrastructure development, and cultivating market entities. The findings aim to provide theoretical references and practical guidance for the high-quality development of tourism in Zhejiang Province.

 摘要： The rapeseed, as the second oilseed crop in China, is an important source of edible oil. Reasonable planting density can improve rapeseed production efficiency, and indirectly increase farmers’ the production enthusiasm of planting rapeseed. To gain a more comprehensive understanding of the study on effect of rapeseed yield to planting density, this article reviews the effect on planting density to yield in rapeseed, including the influences of the interaction between cultivation factors (variety, sowing period, and fertilization), the impact of plant density to lodging resistance and growth and development (biological characteristics, agronomic characteristics, yield traits, and quality tracts), and planting density and the relationship between light and planting density, are reviewed. The lodging resistance of oilseed rape and population yield of different rape varieties can be improved by choosing the appropriate sowing date and fertilizer application, and give full play to the rational utilization of resources and the maximization of benefits. The oilseed rape can make rational use of light and nutrients, which is conducive to dry matter accumulation and yield improvement, with proper planting density. This review will provide a theoretical basis and practical support for rapeseed planting, management, and mechanized production.

 摘要： This paper reviews the research progress on mold detection technologies in milk and dairy products, including rapid test sheet methods, molecular biological detection techniques, metabolomics detection techniques, enzyme-linked immunosorbent assay (ELISA), and microbial rapid photoelectric detection systems, aiming to provide optimal choices for mold detection.

 摘要： [Objectives] To investigate the optimal extraction conditions for anthocyanins from defatted Lycium ruthenicum Murray using ultrasonic-assisted solvent extraction. [Methods] Anthocyanins were extracted from wild L. ruthenicum in Qinghai Province using ultrasonic-assisted ethanol extraction. Through single-factor and orthogonal experiments, the optimal extraction conditions were determined as follows: temperature 50 ℃, solid-liquid ratio 1：15 (g/mL), ethanol concentration 60% (v/v), and ultrasonic extraction time 25 min. Under these conditions, the anthocyanin content of L. ruthenicum was quantified by UV-Vis spectrophotometry at 280 nm. [Results] The extraction yield of anthocyanins from wild Qinghai L. ruthenicum was 17.0 mg/g, which is superior to the yield of 10.0 mg/g obtained by water solvent extraction, representing a 0.7% increase in extraction rate. The anthocyanin content in L. ruthenicum from different regions was determined, revealing that samples from the Chaidamu area in Qinghai had the highest content (17.3 mg/g), while samples from the Gansu area had the lowest (12.0 mg/g). [Conclusions] Ultrasonic-assisted ethanol extraction technology offers advantages including rapid operation, low energy consumption, high extraction yield, simple detection, and safety.

 摘要：  [Objectives] To explore the effects of mixed humus soil and straw ash substrate on rhizosphere bacterial community and growth of hot pepper. [Methods] In this pot experiment, high-throughput sequencing was conducted to analyze bacterial communities in the rhizosphere soil of pepper plants treated with four different HA proportions. [Results] Pepper seedlings exhibited optimal growth in the 6：4 (w/w) HA substrate. Bacterial structure and composition varied with the HA proportion. The relative abundance of the Proteobacteria phylum (ranging from 48.37% to 60.40%) was the highest across all treatments. Correlation analysis indicated that certain bacterial communities were closely related to the availability of soil nutrients and enzymatic activities. [Conclusions] This study elucidates the impact of HA proportion on rhizosphere bacterial communities and plant growth, laying a foundation for understanding the application of different mixed substrates and their effects on soil microbiology.

 摘要： [Objectives] To explore the antibacterial activity of Gouteng Foot Bath Concentrated Liquid. [Methods] The inhibitory activity against Staphylococcus aureus, Escherichia coli, Candida albicans, and Trichophyton rubrum was determined using the mycelial growth rate method. The inhibitory effects of different concentrations of Gouteng Concentrated Liquid on these four microbial strains were analyzed. [Results] Gouteng Foot Bath Concentrated Liquid showed certain antibacterial activity against the above bacteria, and the antibacterial activity against S. aureus, T. rubrum and C. albicans was more significant. [Conclusions] This study provides experimental evidence supporting the application of Gouteng (Uncariae Ramulus Cum Uncis) in antimicrobial foot care products.
