摘    要:以八棱海棠1 a生播种苗为研究时象,对其苗高生长规律和苗高与地径、生态因子的关系等进行研究.试验结果证明:Logistic方程可较好地反映苗高生长规律,苗高生长呈现"慢-快-慢-快-慢"的节律,并以此将苗高年生长过程划分为6个生长期.通过苗高生长规律与气象因子的相关分析,证明日平均气温是影响苗高生长的主要气象因子.

关 键 词:八棱海棠  苗高  日平均气温  年生长规律

Abstract:This paper takes the One-year-old Seedlings of Malus robusta as the research material.The annual height growth rhythms,the relations between height growth and collar diameter of the seedlings and ecological factors were studied.The results showed that the height growth of Malus robusta seedings could be preferable described in rhythm of "slow-fast-slow-fast-slow"by the logistic equation during one year.Based on the rhythms six phases of height growth could be partitioned in one year.By the multivariate regression analysis between seeding height and ecological factors it was found that the daily average temperature was the main factor in influencing the growth of Malus robusta.
Keywords:Malus robusta  Seedling height growth  Daily average temperature  Logistic equation
