摘 要:通过大棚播种床繁殖幼苗、容器培育商品苗是硃砂根规模化生产的重要方式。其中,育苗基质的选择、种子经温水浸种催芽、上盆后管理是提高硃砂根容器实生苗苗木质量的关键技术。以苗高、地径和侧枝数作为硃砂根2年生容器实生苗分级的质量指标,应用SPSS16.0统计软件中的快速聚类法K-Means进行聚类分析,按常规苗木分级等次,将硃砂根2年生容器实生苗分为3级,并制定相应的质量分级标准。It was an important way for large scale production of Ardisia crenata to breed seedlings by greenhouse sowing bed and container seedling.And choosing seedling substrates,soaking seed to hasten germination and management after potting were the key technologies to improve the quality of Ardisia crenata container seedling.The seedling height,ground diameter and lateral branch number were used as the quality index for grading seedlings of 2 year old Ardisia crenata container seedling.By the means of fast clustering method K-Means of the SPSS16.0 statistical software to cluster analysis,according to the conventional seedling grading grades,the 2 year old A.crenat container seedling was divided into 3 levels,and corresponding quality grading standards have been established.
