本论文采用梭罗树种子育苗为研究对象,研究其苗期生长规律,采用“三点法”估算梭罗树苗木的年生长量,用Logistic方程对苗木的年生长进程进行拟合,采用曲线拟合过程,梭罗树实生苗的年生长节律遵循Logistic曲线,通过拟合的方程可以模拟梭罗树一年生实生苗的年生长过程,可预测苗木生长期间的苗高和地径的生长量,有助于对苗木生长动态的跟踪和管理,有利于培育优质壮苗。 In this thesis, the seedling growth of Solon seedlings was studied to study its seedling growth regularity. The annual growth of seedlings of Solon was estimated by “three-point method ”, the annual growth process of seedlings was fitted by Logistic equation, Using curve fitting process, the annual growth rhythm of seedlings of Thunb tree follows the Logistic curve, and the fitting equation can simulate the annual growth of annual seedlings of Thoracic and can forecast the seedling height and diameter growth during seedling growth Quantity, contribute to the dynamic tracking and management of nursery stock growth, is conducive to nurturing high quality seedlings.
