摘要
应用统计分析的方法,通过在设施环境下的栽培试验,对人参根重增长的年变化规律进行了数学模拟,结果表明人参根重积累的变化规律符合S型自然生长曲线。S型自然生长曲线的常见方程式有4种,采用回归方程的F值和相关系数R来比较4个模型的好坏,得出最适宜的数学模型为模型4。通过研究根重积累变化曲线、根重积累速度、根重积累瞬时速度最大值,掌握人参生长过程中的数量规律和特点,为生产上制定科学的栽培管理措施提供依据。
By the cultivation experiment in the condition of installation and with the method of statistical analysis was employed, regulation of ginseng root weight changes were analyzed using mathematical simulation method. The results showed that incretion process of ginseng root weight presents an ＂S＂ natural growth curve. Usual equation of ＂S＂ natural growth curve havd four forms. Numerical value F and relevant coefficient R were employed to compare the model. It is obtained that the mathematical method suitable for ginseng growth was model 4. Increase process of ginseng root weight curve ,weight increase velocity of ginseng root and its extreme value point were analyzed. Quantity regulation and features during ginseng growth were studied. Scientific foundation of cultivation management was provided for ginseng growth.
