【摘要】 为解决塔拉容器实生苗的质量问题,通过对塔拉容器实生苗木的株高、地径、叶片数、根长、地上部分鲜重、地下部分鲜重和全株鲜重指标进行相关分析,得出株高和地径2个指标即能作为塔拉苗木质量数量指标的评价指标。第1次利用株高、地径标准化值总和的一维图和SPSS聚类树状图,对塔拉苗木进行初级分级,尽可能剔除人为误差,再进行修正,达到最终分级。对云南省双柏县安龙堡信么朱不同单株种子培育2个月和3个月的苗子提出了不同的数量指标。更多还原

【Abstract】 In order to solve the problem of grading standards for tara container seedlings, we conducted correlation analysis based on the tara container seedling height, ground diameter, leaf number, root length,shoot fresh weight, underground fresh weight and total plant fresh weight index, and obtained the height and ground diameter as qualitative and quantitative evaluation indexes of tara seedling quality. This was the first time to use plant height, ground diameter standard value of a sum of graphs and SPSS clustering dendrogram for primary classification of tara seedlings, and to eliminate human error as far as possible, then by modification, to reach the final classification. The different indexes were presented for individual plant seed cultivation for 2 months and 3 months of seedling in Shuangbai County Anlongbao of Yunnan Province.更多还原
