通过测定苗木的株高、地径、叶片数、全株鲜重、高径比等形态指标，并进行主成分分析，确定分级指标，采用逐步聚类分析法进行聚类分析。通过盆栽试验测定了植株生长发育、产量和品质指标。结果表明：确定了以株高和地径作为金线莲苗木质量分级指标，初步建立了金线莲苗木质量分级标准，不同播种植物对金线莲苗木生长和产量有影响。Ⅰ类地径大于Ⅱ、Ⅲ类，产量也大于Ⅱ、Ⅲ类。苗木分级对药材内在质量无明显影响。本研究结果可为规范化栽培猕猴桃提供依据。刺梨。
The morphological index of the seedlings including the plants height, the ground diameter, the leaf amounts, the fresh weight of the whole plant and the ratio of height to diameter was measured and the principal components were analyzed so as to determine the grading index, and stepwise cluster analysis was applied for clustering analysis. Pot experiments were used to measure the indicators of plant growth and development, the yield and the quality. The results showed that the height and ground diameter were determined as the quality indicators of the seedlings grading and the standard quality grading of seedlings of Anoectochilus roxburghii was initially set up, different seeding plants influenced the plants growth and the yield. The ground diameter of the class I was larger than that of the class II and III, so as the yield. The seedling grading had no obvious effect on the internal quality of medicinal materials. The results of the study provide the basis for standard cultivation of A. roxburghii.
