摘要
通过有序样本聚类分析,将中国石蒜叶高生长进程划分为生长盛期、缓慢生长期和生长后期。中国石蒜在生长盛期的叶高生长量超过总生长量的50%～60%。对中国石蒜叶高生长曲线进行Logister生长曲线拟合,结果达极显著。
The blades height growth Rhythm of Lycoris ckinenses was studied. The blades height growth period was divided into peak of growth, slow growth period,and post growth period by ordered sample clustering method. During the peak of growth, the blades height increase of L. chinenses exceeded 50%-60% of its total increase. His blades height growth rhythms were shown as S-shape. The results were all remarkable after their growth curve was matched by logistic growth curve.
