运用数理统计方法对出圃前的艾纳香容器苗苗木质量进行抽样调查,在调查可靠性和精度为95%的基础上,采用逐步聚类分析,探讨了艾纳香苗木分级标准。以苗高、地径为分级标准得出艾纳香容器苗苗木分级标准,即Ⅰ级苗为H≥10.4cm、D≥0.34 cm,Ⅱ级苗为H≥7.85 cm、D≥0.23 cm,Ⅲ级苗为H<7.85 cm、D<0.23 cm。为近年大规模发展的艾纳香种植业,提供了苗木质量等级划分的科学依据。
Mathematical statistics was used to sample the quality of seedlings of Anemone container seedlings before the nursery. Based on the survey reliability and accuracy of 95%, stepwise cluster analysis was used to investigate the grading standards of Anemone seedlings. The seedlings of Anemia fragrant seedlings were graded according to the height of seedling and the diameter of ground, that is, Grade Ⅰ seedlings were H≥10.4cm, D≥0.34cm, Grade Ⅱ seedlings were H≥7.85cm, D≥0.23cm, Ⅲ Seedlings were H <7.85 cm and D <0.23 cm. For the large-scale development in recent years, Ainai planting industry, providing a scientific basis for the classification of seedling quality levels.
