以混凝土百页片围墙作保护屏障,占地面积30.70亩,建成可保存2000份种质的“国家种质沅江苎麻圃”;采用“三圃制”繁殖入圃无病(根腐线虫病)无性系种质1027份,为妥善保存我国苎麻资源及提供利用打下了良好基础。对5种无性繁殖技术的应用表明,嫩枝扦插繁殖技术是适应大批量快速繁殖苎麻无病无性系种质以加速建圃进程与安全保种的最佳繁殖技术。
Covering an area of 30.70 acres with a hundred-piece wall made of concrete, a “national germplasm Yuanjiang ramie garden” that can preserve 2,000 germplasms was established; the “Three-nursery system” was used to breed nursery-free disease (root rot nematode disease) Clonal germplasm 1027, in order to properly preserve our ramie resources and provide a good foundation. The application of five kinds of asexual propagation technology showed that the softwood cuttage propagation technology is the best propagation technology to adapt to the rapid propagation of ramie disease-free clones germplasm in large quantities in order to speed up the process of construction and safe seed protection.
