以千年桐1年生播种苗为研究对象，对其苗高、地径的生长规律和苗高、地径与气象因子的关系等进行研究。试验结果表明：Logistic方程可较好地反映1年生千年桐的苗高、地径生长规律；日平均气温是影响苗高生长的主要气象因子，气象因子与地径生长关系不大。
以韆年桐1年生播種苗為研究對象，對其苗高、地徑的生長規律和苗高、地徑與氣象因子的關繫等進行研究。試驗結果錶明：Logistic方程可較好地反映1年生韆年桐的苗高、地徑生長規律；日平均氣溫是影響苗高生長的主要氣象因子，氣象因子與地徑生長關繫不大。

Taking one-year-old Aleurites montana seedlings as the research object ,the growth law of seedling height& ground diameter ,the relations among seedling height ,ground diameter & weather factors were studied .Result shows that :Logistic equation can optimally reflect the growth law of seedling height ,ground diameter ;the average daily temperature is the main meteorological factors affecting height grow th of seedlings ;meteorological factors has little relationship with ground diameter .
