美国 再造林、苗圃和遗传资源（RNGR）计划 – 美国林务局种苗研究资源平台

计划背景与设立单位

RNGR（Reforestation, Nurseries, and Genetic Resources，再造林、苗圃和遗传资源计划）由美国农业部林务局（USDA Forest Service）下辖的州、私营与部落林业副署（State, Private, and Tribal Forestry deputy area）主持建设，定位是该副署面向公众发布林业育苗技术资料的核心门户。源站关于页明确写到，林务局是自然资源管理科学领域公认的领导者之一，州、私营与部落林业副署的使命之一正是与合作机构共同开发并发布技术信息，RNGR 就是为把这类信息集中放到一个站点上而建出来的；其服务对象是需要为造林或生态保护培育苗木的从业人员、研究人员与机构管理者，同时面向有兴趣参与其中的个人与志愿者。

文章数据库与历史出版物

源站 publications 页面明确写明，RNGR.net 维护着一个可检索的技术文章库，收录数量在 11000 篇以上，绝大部分可以下载 PDF，目前仍持续在增加条目。最早的一本核心期刊是《Tree Planters’ Notes 植物种植者笔记》，创办于 1950 年，定位是面向林业育苗与苗木上山（outplanting）一线操作的技术转移平台，涵盖树木、灌木以及用于再造林、保护与恢复的本土植物；1993 年起 RNGR 还另出一本姊妹刊《Forest Nursery Notes 苗圃笔记》，作为情报性季刊定期摘录与点评行业内的新书、新工具与新论文，这份摘要型季刊一直出版到 2015 年才停刊。此外还并入了一个跨度更长、收录最完整的《National Nursery Proceedings 全国苗圃年会论文集》系列，源站给出的最早条目是 1949 年，一直延续至今，与各届北美苗圃协会联合会的年会并行。

三本核心手册

源站 publications 子页把三本手册单列为一类。第一本是《The Container Tree Nursery Manual 容器育苗手册》，分卷详细讲解在容器中培育树木与木本灌木苗木的全流程，包括场地建设、基质选择、灌溉施肥、病虫害与苗木质量分级等；第二本是《Tropical Nursery Manual 热带苗圃手册》，专门面向热带地区的原生植物与传统作物苗圃编写，从苗圃选址到育苗、施肥、出圃、运苗都给出可操作指南；第三本是《The Woody Plant Seed Manual 木本植物种子手册》，按章节展开种子生物学、采收、处理、储藏、活力测定和苗圃实务等内容，被多家林业机构用作种苗工作者的案头书。三本手册都按章节开放下载，被源站重点标注为「永久免费提供」的核心技术资源。

国家种子实验室、目录与原生植物网络

RNGR 门户同时托管三类与苗圃实务紧密相关的公共资源。其一是 National Seed Laboratory 国家种子实验室，归美国农业部林务局直接运行，专门为森林与保护性苗圃提供种子质量检测、储藏方案与遗传鉴定咨询服务，该实验室成立于 1954 年，是北美同类设施中唯一由联邦机构运行的种子检测与研发基地；其二是 National Nursery and Seed Directory 全国苗圃与种子目录，是一个面向全美和加拿大地区、专门收录支持森林与本土植物材料繁育业务的在线企业目录，用户可按州、产品或业务类型检索供应商；其三是 Native Plant Network 原生植物网络，主要面向北美（加拿大、美国和墨西哥）的原生植物种植与保育人士，提供育苗协议数据库、技术培训资料与同行交流渠道，应用范围覆盖生态恢复、再造林、景观美化等多个方向。

About the RNGR Plan

RNGR (Reforestation, Nurseries, and Genetic Resources) is a technology-information portal built and maintained by the State, Private, and Tribal Forestry deputy area of the USDA Forest Service. The About page of the source site states that the Forest Service is widely recognized as a leader in the science of natural resource management, and that one of the missions of the deputy area is to develop and disseminate technical information in partnership with cooperating organizations; RNGR is the public face of that work, aimed at people who grow forest and conservation seedlings, the organizations and agencies that support them, and individuals who want to learn more about nursery production, tree improvement, seed handling and native plant restoration.

Article Database and Serial Publications

The Publications page of the source site describes RNGR.net as a searchable database of over 11,000 technical articles, the great majority available for download in PDF and continuously updated. Its longest-running serial is Tree Planters’ Notes, founded in 1950 as a technology-transfer venue for nursery production and outplanting of trees, shrubs and native plants used in reforestation, conservation and restoration. From 1993 the team also produced a companion abstract-and-newsletter, Forest Nursery Notes, which ran through 2015. In addition, RNGR hosts the National Nursery Proceedings, the conference paper series of the U.S. and Canadian forest and conservation nursery associations, whose earliest entries go back to 1949 and which still receives new proceedings every year.

Three Manuals at the Core

Three reference manuals sit at the centre of the site’s downloads. The Container Tree Nursery Manual is a multi-volume guide to producing tree and woody-shrub seedlings in containers, covering site layout, media, irrigation, fertilization, pest management and seedling quality grading. The Tropical Nursery Manual is written specifically for nurseries of native and traditional plants in tropical climates and walks the reader through site selection, propagation, fertilization, handling and shipping. The Woody Plant Seed Manual covers seed biology, collection, processing, storage, testing and nursery practice for a wide range of forest and conservation species. All three are organized by chapter and offered as free downloads from the source site.

National Seed Lab, Directory and Native Plant Network

Alongside the publications, RNGR hosts three further public resources. The National Seed Laboratory is operated by the USDA Forest Service as a national facility providing seed testing, storage research and genetic-identity services to forest and conservation nurseries; the lab was established in 1954 and remains the only federally run forest-seed laboratory in North America. The National Nursery and Seed Directory is an online directory of businesses in the United States and Canada that support the propagation of forest and native plant materials, searchable by state, product or business type. The Native Plant Network provides technical and practical information on growing and outplanting North American native plants (Canada, the United States and Mexico) for restoration, conservation, reforestation and landscaping work.
