    Grazing in grassland ecosystems has substantial ecological repercussions. Overgrazing impedes vegetation growth and can result in its decline, leading to alterations in plant community composition and soil compaction, thereby elevating the risks of water and nutrient loss. Furthermore, livestock excrement impacts soil nutrient cycling, potentially contributing to soil erosion and degradation. Grazing also exerts an influence on grassland biodiversity. Ensuring the vitality of grasslands necessitates responsible grazing management. This encompasses regulating grazing intensity, adopting rotational grazing practices, and implementing effective grassland rotation methods. Ongoing monitoring and educational efforts are indispensable. Rotational grazing entails the division of grazing areas, seasonal animal rotation, and designated rest periods, all of which foster vegetation growth, soil health, and ecological stability. Mixed grazing, featuring different livestock species, can enhance operational efficiency and ecological benefits. The success of mixed grazing hinges on considerations of compatibility, dietary requirements, and vigilant monitoring.

    Effective detection of rice diseases is an important subject to improve the yield and quality of rice. Convolution neural network (CNN) is widely used in plant disease detection, but a large number of training samples are needed to build the model. In this paper, a biphasic method based on CNN is proposed, which can simplify training samples. This method takes into account a variety of rice diseases and a prediction accuracy of 88.9%. Using this method can effectively establish a rice disease dataset, accurate detection, and disease classification. There are three novelties in this paper: (1) a dual-phase approach capable of learning from a small rice grain disease dataset has been proposed; (2) a smart segmentation procedure has been proposed which is capable of handling heterogeneous backgrounds prevalent in plant disease image datasets collected in real-life scenarios; (3) experimental comparison has been provided with straightforward use of improved CNN architectures on the small rice grain dataset to show the effectiveness of the proposed approach.

    Now cross-border e-commerce has become an important trend in the development of international trade. In recent years, in the export mode of China’s foreign trade, the proportion of products relying on cross-border e-commerce is increasing year by year. During the epidemic of COVID-19, China’s cross-border e-commerce trade volume rose instead of falling and has become an important part of foreign trade. Qingdao has a good geographical advantage, opening up a new world of cross-border e-commerce and aquatic products export trade. However, there are still many problems in the export of aquatic products relying on cross-border e-commerce. Yu (2022, DOI: 10.50908/grb.1.0_71) makes an in-depth analysis of the current situation of Qingdao’s aquatic products export, finds out the bottleneck restricting the development of Qingdao’s cross-border e-commerce, and gives the corresponding countermeasures and suggestions.
