What if we could fight farm weeds with a precise strike instead of blanket chemicals? This vision is now becoming a reality in the farmlands of China. The HG LaserWeederr, a new machine developed by Huagong Tech, marks a major breakthrough in precision agriculture by making targeted weed control a practical reality.
This advancement responds directly to the persistent problems associated with traditional farming. Decades of heavy reliance on chemical herbicides (除草剂) have caused significant environmental harm, including soil degradation and water pollution. For China, a nation with vast agricultural lands, finding a sustainable solution is a matter of particular urgency.
So, how does this “robot farmer” work? At its core, it combines artificial intelligence with advanced light technology. Its AI-powered visual system, trained on a vast database of plant images, acts as a smart “eye” that can distinguish weeds from crops in milliseconds. Once a weed is spotted, the robot delivers a precise laser beam (激光束) to each weed’s growth center, destroying key cells and causing the plant to die naturally, all without harming the surrounding crops or the soil.
The advantages of this approach are substantial. In terms of efficiency, an advanced model equipped with 32 laser heads can destroy up to 320,000 weeds per hour, which is four to eight times more efficient than traditional methods. Through continuous operation, it achieves a weed control rate of over 95%, far outperforming hand weeding and obviating the need for this back-breaking task. Ecologically, it significantly reduces the use of chemicals, thereby cutting off a primary source of agricultural pollution.
The introduction of this technology is part of a broader shift toward automated and sustainable agriculture in China and abroad. As farms worldwide seek to enhance efficiency while minimizing environmental impact, robotic solutions like the Hg LaserWeeder are likely to become increasingly common. This technology signals a move toward precision agriculture, where data-driven tools enable farmers to manage their crops with greater accuracy and less dependence on chemicals, pointing the way for a cleaner, more efficient future for farming.

【导语】本文主要介绍了华工科技研发的新型机器HG LaserWeeder，介绍了其研发背景、工作原理、优势以及该技术对国内外精准可持续农业发展的意义。
【第1题详解】细节理解题。根据第二段中的“Decades of heavy reliance on chemical herbicides (除草剂) have caused significant environmental harm, including soil degradation and water pollution. For China, a nation with vast agricultural lands, finding a sustainable solution is a matter of particular urgency.(几十年来，对化学除草剂的严重依赖已经对环境造成了重大危害，包括土壤退化和水污染。对于中国这个农业大国来说，找到一个可持续的解决方案尤为紧迫。)”可知，HG LaserWeeder研发的主要因素是化学物质造成的污染。
【第2题详解】细节理解题。根据第三段中的“Its AI-powered visual system, trained on a vast database of plant images, acts as a smart “eye” that can distinguish weeds from crops in milliseconds.(其人工智能视觉系统基于庞大的植物图像数据库进行训练，就像一只智能“眼睛”，能在毫秒内区分杂草和作物。)”可知，HG LaserWeeder视觉系统的主要作用是识别目标杂草。
【第3题详解】词句猜测题。根据第四段中的“Through continuous operation, it achieves a weed control rate of over 95%, far outperforming hand weeding and obviating the need for this back-breaking task.(经持续作业，其除草率超95%，效果远超人工除草，并且obviating了这项繁重劳作的需求。)” 可知，激光除草效率极高，不再需要人工除草，由此推断obviating 表示“消除、免去”，与Removing含义相近。
【第4题详解】推理判断题。根据最后一段中的“As farms worldwide seek to enhance efficiency while minimizing environmental impact, robotic solutions like the Hg LaserWeeder are likely to become increasingly common. This technology signals a move toward precision agriculture, where data-driven tools enable farmers to manage their crops with greater accuracy and less dependence on chemicals, pointing the way for a cleaner, more efficient future for farming.(随着全球农场寻求在提高效率的同时尽量减少对环境的影响，像Hg LaserWeeder这样的机器人解决方案可能会越来越普遍。这项技术标志着向精准农业的转变，数据驱动的工具使农民能够更精确地管理作物，减少对化学物质的依赖，为更清洁、更高效的农业未来指明了方向。)”可推知，未来的农业将更多地依赖智能机器人工具。

倘若我们能精准打击农田杂草，而非大面积喷洒化学药剂，结果会怎样？这一构想如今正在中国的农田里成为现实。由华工科技研发的新型设备——HG激光除草机，让靶向除草从概念走向实用，标志着精准农业领域的一项重大突破。
这一技术进步直击传统农业长期存在的痛点。数十年来，农业生产高度依赖化学除草剂，已造成严重的环境破坏，包括土壤退化和水体污染。对拥有广袤耕地的中国而言，寻找可持续的解决方案尤为迫切。
那么，这位“机器人农夫”是如何工作的？其核心是人工智能与先进光学技术的结合。它搭载的AI视觉系统经过海量植物图像数据训练，如同一双智能“眼睛”，能在毫秒间区分杂草与农作物。一旦发现杂草，机器人便会向其生长点发射精准激光束，破坏关键细胞，使其自然枯死，全程不会伤及周边作物与土壤。
这种除草方式的优势十分显著。
在效率方面，配备32个激光头的高端机型每小时可清除多达32万株杂草，效率是传统方式的4至8倍。通过持续作业，其除草率可达95%以上，远优于人工除草，也让这项繁重的体力劳动不再必要。
在生态方面，它大幅减少了化学药剂的使用，从源头切断了农业污染的主要来源之一。
这项技术的推广，是国内外农业向自动化、可持续化转型的重要一环。随着全球各地的农场都在追求提升效率、降低环境影响，HG激光除草机这类智能设备未来将愈发普及。该技术标志着精准农业的发展方向：依托数据化工具，农民能更精准地管理作物，减少对化学药剂的依赖，为农业开辟出更清洁、更高效的发展道路。
