摘要: 青檀是我国特有的纤维树种，为国家一级重点保护植物，主要分布于安徽、福建、浙江、湖北等19个省区。青檀常生于石灰岩山区沟谷溪畔疏林中，是石灰岩、砂岩、山地、河岸造林的先锋树种。此外，青檀集造纸、木材、饲料、药用价值于一体，尤其是青檀韧皮纤维的独特性能，是制作宣纸不可替代的原料，具有重要的市场价值。查阅相关论文文献发现，国外对青檀的研究较少，而目前国内对青檀的研究相对较多，但多局限于种子繁育、开发利用、造林试验等试验研究方向。许多科研机构或企业正在研究林木种质创新的关键技术及商业化开发，但对青檀种质创新的研究较少。市面上仅有一本由南京林业大学编写的《中国青檀》一书，但尚未见有关青檀育种的研究。

Abstract: Pteris chinensis is a fiber tree species unique to my country and a national first-class protected plant. It is mainly distributed in 19 provinces and regions including Anhui, Fujian, Zhejiang, and Hubei. Pteris chinensis often grows in sparse forests along valleys and streams in limestone mountainous areas. It is a pioneer tree species for afforestation of limestone, sandstone, mountainous areas, and riverbanks. In addition, Pteris chinensis combines papermaking, wood, feed, and medicinal values. In particular, the unique properties of Pteris chinensis bast fiber are irreplaceable raw materials for making rice paper and have important market value. After consulting relevant papers and literature, it was found that there are few studies on Pteris chinensis abroad, while there are relatively more studies on Pteris chinensis in China, but most of them are limited to experimental research directions such as seed breeding, development and utilization, and afforestation experiments. Many scientific research institutions or enterprises are studying the key technologies and commercial development of forest germplasm innovation, but there are few studies on Pteris chinensis germplasm innovation. There is only one book on the market, "Chinese Pteris chinensis", compiled by Nanjing Forestry University, but no research on Pteris chinensis breeding has been seen.
