中国推出了首个开源大型语言模型——绿盾，用于提升作物保护。该模型由南京农业大学联合国家农业生物安全重点实验室及三十多家行业机构共同开发，旨在提供科学的农业指导，确保农药合理使用。

China has launched its first open-source large language model, Green Shield for better crop protection, developed by Nanjing Agricultural University in partnership with the National Key Laboratory of Agricultural Biosafety and over 30 industry institutions, the model is designed to offer scientific agricultural guidance and ensure proper pesticide use.

项目负责人董树猛表示，中国经常面临农作物病虫害频发和农药抗性问题。

Dong Shemeng, project leader, said that China faces frequent crop pest outbreaks and the issue of pesticide resistance.

董树猛同时也是南京农业大学植物保护学院的副院长，他表示，基层农民迫切需要专业的指导。

Dong, who is also vice dean of the College of Plant Protection at Nanjing Agricultural University, said that farmers urgently need professional guidance at the grassroots level.

然而，通用大型语言模型在回答植物保护问题时常常给出不准确的答案，更严重的是，它们提供的农药使用建议标准混乱，有时甚至存在风险。

However, general purpose large language models often provide inaccurate answers to plant protection questions and, more critically, give poorly standardized, sometimes risky advice on pesticide use to solve the problem.

团队构建了一个包含超过25亿个词元的专用语料库，来源包括学术论文、专利、国家标准和田间报告。

The team built a specialized corpus of over 2,500,000,000 tokens from academic papers, patents, national standards, and field reports.

这个语料库覆盖了水稻、小麦、大豆、蔬菜和果树等主要作物，整合了病虫害监测、绿色防控措施和农药登记信息。

The corpus covers major crops, including rice, wheat, soybeans, vegetables, and fruit trees, and integrates information on pest monitoring, green control measures, and pesticide registration.

南京农业大学信息管理学院的王东波教授表示，该模型能精准识别作物种类、生长阶段以及病害症状。

Wang Dongbo, a professor at the College of Information Management of Nanjing Agricultural University said the model can precisely identify crop types, growth stages, and symptoms of crop diseases.

随后，它会生成综合性的生长管理方案。

It then generates integrated growth control strategies.

王教授指出，经过针对性训练后，模型收敛效果很好，对病虫害的识别准确率很高。

Wong noted that with targeted training, the model converges well and recognizes pests with high precision.

在提出任何建议之前，模型会自动比对国家农药登记数据库，核实每种化学药剂是否在禁用名单上、是否适用于相关作物，以及剂量是否合规。

Before presenting any recommendation, the model automatically cross references the National Pesticide Registration Database to verify each chemical against banned lists, approved crops, and dosage limits.

任何不符合规定的建议都会被自动拦截并修正，从源头上防止农药滥用。

Any noncompliant suggestion is blocked and self corrected, preventing pesticide misuse at the source.

今年1月至4月，中国主要工业企业利润同比增长18.2%，高于第一季度15.5%的增幅。

Profits of China's major industrial firms increased 18.2% year on year during the January April period, surpassing a rise of 15.5% in the first quarter.

国家统计局数据显示，年主营业务收入达两亿元人民币（约合293万美元）以上的工业企业，今年前四个月累计利润达到2.44万亿元。

According to the National Bureau of Statistics, industrial firms with annual main business revenue of at least 20,000,000 yuan (about $2,930,000 ) saw their combined profits reach 2,440,000,000,000 yuan in the first four months.

国家统计局的数据显示，仅四月份，重点工业企业的利润就同比增长了24.7%。

Data from the National Bureau of Statistics shows that in April alone, profits of major industrial firms rose 24.7 compared to a year earlier.

中国科学院科技战略咨询研究院发布了《科技创新与未来产业发展蓝皮书》，为各行业把握前沿技术、谋划未来发展提供决策参考。

The Institutes of Science and Development under the Chinese Academy of Sciences has released a blue book on sci tech innovation and Development of Future Industries, providing decision making support for various sectors to grasp cutting edge technologies, and plan for future development.

这份蓝皮书系统梳理了人工智能、具身智能、量子信息、生物制造和聚变能源等12个重点领域的技术路线图、竞争格局和产业化路径。

The Blue Book outlines technological roadmaps, competitive landscapes, and industrialization pathways across 12 key areas, including general artificial intelligence, embodied intelligence, quantum information, biomanufacturing, and fusion energy.

报告还提出了推动中国未来产业高质量发展的总体框架。

It also proposes a general framework for promoting the high quality development of China's future industries.

研究团队指出，未来产业的发展具有非线性和涌现性特征，需要基础研究、技术突破、资本投入和制度创新协同推进。

According to the research team, the development of future industries is characterised by nonlinearity and emergent properties requiring coordinated progress in basic research, technological breakthroughs, capital support, and institutional innovation.

中国科学院科技战略咨询研究院院长潘教峰表示，新一轮科技革命和产业变革正在深入推进，全球科技创新正进入活跃密集期。

Pan Zhaofeng, President of the Institutes of Science and Development under the Chinese Academy of Sciences, said that a new wave of technological revolution and industrial transformation is deepening, with global scientific and technological innovation entering an active and intensive phase.
