近日观测中心传出重要预警:昨日研究机构公开最新成果,“扦插BB技术：高效繁殖植物的新选择——视频详解”

在园艺和植物繁殖领域，扦插BB技术因其高效、便捷的特点而备受关注。BB扦插，全称为“植物细胞组织培养与生根”，是一种利用植物细胞分裂和再生能力，通过无性繁殖快速繁殖植物的方法。下面，我们就来详细了解一下扦插BB技术的优势，并通过视频学习如何操作。 ### 扦插BB技术的优势 1. **繁殖速度快**：相比传统的播种繁殖，扦插BB技术可以在短时间内大量繁殖植物，大大缩短了植物生长周期。 2. **繁殖成功率高**：通过控制培养环境，如温度、湿度、光照等，可以确保扦插的成功率。 3. **遗传稳定性好**：扦插繁殖的植物与母本具有相同的遗传特性，保证了品种的纯度。 4. **不受季节限制**：在室内可控环境下，扦插BB技术可以全年进行，不受季节影响。 5. **减少病虫害**：由于扦插繁殖的植物与母本相同，减少了病虫害的发生。 ### 扦插BB技术的操作步骤 1. **选择健康植株**：选择生长健壮、无病虫害的植株作为扦插材料。 2. **制备培养基**：根据植物种类和生长需求，制备适宜的培养基。 3. **切割扦插材料**：将植株切割成一定长度的枝条或叶片，注意切口要平滑。 4. **消毒处理**：对扦插材料进行消毒，防止细菌感染。 5. **接种培养**：将消毒后的扦插材料接种到培养基上，放入培养箱中。 6. **观察管理**：定期观察培养箱内的植物生长情况，调整培养条件。 7. **生根与移栽**：当扦插材料生根后，将其移栽到适宜的土壤中，继续培育。 ### 视频学习 为了更好地了解扦插BB技术，以下是一段视频教程，详细介绍了该技术的操作步骤： [视频链接] 通过观看视频，您可以直观地学习到扦插BB技术的操作方法，掌握这一高效繁殖植物的新技巧。 总之，扦插BB技术是一种高效、便捷的植物繁殖方法，具有繁殖速度快、成功率高等优点。掌握这一技术，可以帮助园艺爱好者快速繁殖心爱的植物，丰富自己的植物品种。同时，通过视频学习，相信您也能轻松掌握这一技术，为园艺事业贡献自己的力量。

TMTPOST --   Chinese telecommunications giant Huawei unveiled a sweeping expansion of its artificial intelligence computing ambitions on Thursday, announcing new supercomputing systems powered by its in-house Ascend chips. The move signals escalating competition with U.S. chipmaker Nvidia, the global leader in AI processors.AI-generated imageAt its annual Huawei Connect conference in Shanghai, the company introduced the forthcoming "Atlas 950 SuperCluster," which it said will begin rolling out as early as next year. The announcement underscores Huawei ’ s determination to challenge U.S. dominance in advanced AI hardware despite Washington ’ s tightening export controls on semiconductors."The competition has undeniably arrived and is gaining momentum," an Nvidia spokesperson said. "Customers will choose the best technology stack for running the world ’ s most popular commercial applications and open-source models."U.S. restrictions have cut China off from the most advanced chips needed to train large-scale AI models, forcing Chinese firms to rely on domestically developed processors or stockpiles of older foreign components. Huawei, long targeted by U.S. sanctions, has turned to large-scale clustering of its less powerful but increasingly refined Ascend processors. By combining vast numbers of these chips in interconnected networks, the company aims to match or surpass the performance of systems built on Nvidia ’ s hardware.Huawei said it plans to release three new versions of its Ascend chips through 2028, pledging to double computing power with each iteration. At the base level, its new Atlas 950 supernode will connect 8,192 Ascend chips. A full Atlas 950 SuperCluster would integrate more than 500,000 chips.A future upgrade, the Atlas 960 system slated for 2027, is projected to support nearly 15,500 chips per node and scale to more than 1 million Ascend processors across a full supercluster. Huawei claimed these would represent the world ’ s most powerful AI systems by raw computing power.Huawei did not shy away from comparisons with its American rival. Eric Xu, the company ’ s vice chairman and rotating chairman, said the Atlas 950 supernode would deliver 6.7 times more computing power than Nvidia ’ s upcoming NVL144 system. He went further, predicting Huawei would "be ahead on all fronts" compared with Nvidia ’ s 2027 offering — and claimed the Atlas 950 SuperCluster would even exceed the computing capacity of Elon Musk ’ s xAI Colossus project.While independent verification of Huawei ’ s claims is limited, industry experts said the company ’ s ambition is clear."Huawei ’ s announcement on its computing breakthrough is well timed with recent increasing emphasis by the Chinese government on self-reliance on China ’ s own chip technologies," said George Chen, partner and co-chair of the digital practice at The Asia Group. While noting that Huawei might be overstating its technical edge, he added, "the ambition to be a world AI leader cannot be underestimated."Research from SemiAnalysis earlier this year found that Huawei ’ s CloudMatrix system outperformed Nvidia ’ s equivalent despite each Ascend processor offering only about one-third the power of an Nvidia chip. The advantage came from scale: Huawei deployed roughly five times as many chips in its clusters."Computing power has and will continue to be the key for AI," Xu emphasized during his keynote speech in Shanghai.Huawei ’ s new announcements build on earlier efforts. Two years ago, it introduced the Atlas 900 SuperCluster, which it still markets with "thousands" of Ascend chips. On Thursday, the company said it had already deployed more than 300 Atlas 900 A3 supernodes to over 20 clients across telecoms, manufacturing, and other sectors.This momentum reflects a broader push within China to substitute foreign technology with homegrown alternatives. Beijing has increasingly pressed domestic firms to use local suppliers and invest in national semiconductor capabilities. Huawei ’ s breakthroughs are likely to be touted as proof of progress in these efforts.Huawei ’ s offensive comes as Nvidia faces growing headwinds in China, once one of its most important markets. Earlier this week, China extended an antitrust probe into the U.S. company over alleged monopolistic practices. On Wednesday, Nvidia ’ s shares fell more than 2% after the Financial Times reported that Beijing had ordered Chinese tech giants to halt testing and purchases of the RTX Pro 6000D, one of Nvidia ’ s new AI-focused chips.Nvidia Chief Executive Jensen Huang expressed frustration over the developments. "I am disappointed to hear this news," he told reporters, while reiterating that Huawei represents a "formidable" competitor.The geopolitical context adds another layer of complexity. The U.S. and China concluded trade talks in Spain this week that reportedly included discussions over the fate of TikTok, the video app owned by Beijing-based ByteDance. But technology co
