目的为改变当前黄芩种苗质量标准模糊不清的问题,在陇西自然生态环境条件下,对当地黄芩种苗进行分级研究,为系统的黄芩标准化种植奠定基础。方法将黄芩种苗按照根粗、根长依次分为一级苗(根长>15 cm,直径3~5 cm)、二级苗(根长10~15 cm,直径3~5 cm)、三级苗(根长8~<10 cm、直径2~<3 cm)和未分级苗,观测不同种苗移栽后田间出苗率、生长状况及药用部位(根部)的亩产量、产籽量和根长、根质量、根粗情况,并对黄芩种苗分级移栽后的经济效益进行实效分析。结果不论是出苗率、根部分支数、田间株高、亩产量、产籽量还是根质量、根粗均表现为一级苗最好,其次为二级苗,未分级苗为第三,三级苗最差。结论本试验关于黄芩种苗的分级处理方案符合陇西黄芩生产实际,并能够带来良好的经济效益。建议将本研究种苗分级处理方案确定为陇西同类地区黄芩生产种苗分级标准。
Objective To change the obscure problem of the quality standard of Scutellaria baicalensis seedlings, to study the grading of Scutellaria baicalensis seedlings under the natural ecological environment of Longxi, which laid the foundation for systematic cultivation of Scutellaria baicalensis. Methods Scutellaria baicalensis seedlings were divided into primary seedlings (root length> 15 cm, diameter 3 ~ 5 cm), secondary seedlings (root length 10 ~ 15 cm, diameter 3 ~ 5 cm) Seedlings (root length of 8 ~ <10 cm, diameter of 2 ~ <3 cm) and unclassified seedlings were observed. The seedling emergence rate, growth status and medicinal parts (root) And root length, root quality, root diameter and rough conditions, and the economic benefits of skullcap seedlings after grading transplanting were analyzed. The results showed that no matter the seedling emergence rate, the root branch number, the field plant height, the mu yield, the seed yield or the root quality, the root diameter showed the best for the first grade seedlings, followed by the second grade seedlings, the unclassified seedlings for the third grade and the third grade The worst seedlings. Conclusion Scutellaria baicalensis seedling grading treatment program in line with the actual production of skullcap, and can bring good economic benefits. It is suggested that the seedling grading scheme should be determined as grading standard of baicalin production in similar areas in Longxi.
