【摘要】 以16个欧榛品种为试材,用L og istic M odel、G om pertz M odel、R ichards M odel等数学模型对欧榛不同品种嫁接苗、插条苗、实生苗的年生长规律进行了模拟,利用CurveExpert等软件进行分析。结果发现3类苗木的各个指标的生长变化均呈现“慢-快-慢”的规律,生长曲线基本呈“S”形。更多还原

【Abstract】 Taken 16 cultivars of Corylus avellana L.as materials,the annual growth rhythm of grafted seedling,cutting and seedling were analyzed applying analysis software,such as Curve Expert,and simulated by Logistic Model,Gompertz Model,Richards Model.The results showed that all indexes of 3 types of nursery stock displayed slow-fast-slow growth rhythm,and the growth curves showed S-shaped basically.更多还原
